With permanent human presence onboard the International Space Station (ISS), and long duration space missions being planned for the moon and Mars, humans will be living and working in microgravity over increasingly long periods of time. In addition to weightlessness, the confined nature of a spacecraft environment results in ergonomic challenges such as limited visibility, and access to the activity area. These challenges can result in prolonged periods of unnatural postures for the crew, ultimately causing pain, injury, and loss of productivity. Determining the right set of human factors requirements and providing an ergonomically designed environment is crucial to mission success. While a number of general purpose restraints have been used on ISS (handrails, foot loops), experience has shown that these general purpose restraints may not be optimal, or even acceptable for some tasks that have unique requirements. For example, some onboard activities require extreme stability (e.g., glovebox microsurgery), and others involve the use of arm, torso and foot movements in order to perform the task (e-g. robotic teleoperation); standard restraint systems will not work in these situations. The Usability Testing and Analysis Facility (WAF) at the NASA Johnson Space Center began evaluations of crew restraints for these special situations by looking at NASAs Robonaut. Developed by the Robot Systems Technology Branch, Robonaut is a humanoid robot that can be remotely operated through a tetepresence control system by an operator. It was designed to perform work in hazardous environments (e.g., Extra Vehicular Activities). A Robonaut restraint was designed, modeled for the population, and ultimately tested onboard the KC-135 microgravity aircraft. While in microgravity, participants were asked to get in and out of the restraint from different locations, perform maximum reach exercises, and finally to teleoperate Robonaut while in the restraint. The sessions were videotaped

The current International Space Station configuration includes a Japanese Experiment Module which relies on a large manipulator and a smaller dexterous manipulator to operate outside the pressurized environment of the experiment module. The module's flight demonstration is a payload that will be mounted in the aft flight deck on STS-87 to evaluate a prototype of the dexterous manipulator. Since the payload operations entail two 8-hour scenarios on consecutive days, adequate operator restraint at the workstation will be critical to the perceived success or failure of the payload. Simulations in reduced gravity environment on the KC-135A were the only way to evaluate the restraint systems and workstation configuration. Two astronaut and two non-astronaut operators evaluated the Advanced Lower Body Extremities Restraint Test and a foot loop restraint system by performing representative tasks at the workstation in each of the two restraint systems; at the end of each flight they gave their impressions of each system and the workstation. Results indicated that access to the workstation switch panels was difficult and manipulation of the hand controllers forced operators too low for optimal viewing of the aft flight deck monitors. The workstation panel should be angled for better visibility, and infrequently used switches should be on the aft flight deck panel. Pitch angle and placement of the hand controllers should optimize the operator's eye position with respect to the monitors. The lower body restraint was preferred over the foot loops because it allowed operators to maintain a more relaxed posture during long-duration tasks, its height adjustability allowed better viewing of aft flight deck monitors, and it provided better restraint for reacting forces imparted on the operator at the workstation. The foot loops provide adequate restraint for the flight demonstration tasks identified. Since results will impact the design of the workstation, both restraints should be

Since 2000, numerous improvements have been made to the National Association for Stock Car Auto Racing, Incorporated (NASCAR®) driver restraint system, resulting in improved crash protection for motorsports drivers. Advancements have included seats, head and neck restraints (HNRs), seat belt restraint systems, driver helmets, and others. These enhancements have increased protection for drivers from severe crash loading. Extending protection to the driver's extremities remains challenging. Though the drivers' legs are well contained for lateral and vertical crashes, they remain largely unrestrained in frontal and frontal oblique crashes. Sled testing was conducted for the evaluation of an energy-absorbing (EA) toe board material to be used as a countermeasure for leg and foot injuries. Testing included baseline rigid toe boards, tests with EA material-covered toe boards, and pretest positioning of the 50th percentile male frontal Hybrid III anthropomorphic test device (ATD) lower extremities. ATD leg and foot instrumentation included foot acceleration and tibia forces and moments. The sled test data were evaluated using established injury criteria for tibial plateau fractures, leg shaft fractures, and calcaneus, talus, ankle, and midfoot fractures. A polyurethane EA foam was found to be effective in limiting axial tibia force and foot accelerations when subjected to frontal impacts using the NASCAR motorsport restraint system.

The effects of ventricular restraint level on left ventricular reverse remodeling are not known. We hypothesized that restraint level affects the degree of reverse remodeling and that restraint applied in an adjustable manner is superior to standard, nonadjustable restraint. This study was performed in 2 parts using a model of chronic heart failure in the sheep. In part I, restraint was applied at control (0 mm Hg, n = 3), low (1.5 mm Hg, n = 3), and high (3.0 mm Hg, n = 3) levels with an adjustable and measurable ventricular restraint (AMVR) device. Restraint level was not altered throughout the 2-month treatment period. Serial restraint level measurements and transthoracic echocardiography were performed. In part II, restraint was applied with the AMVR device set at 3.0 mm Hg (n = 6) and adjusted periodically to maintain that level. This was compared with restraint applied in a standard, nonadjustable manner using a mesh wrap (n = 6). All subjects were followed up for 2 months with serial magnetic resonance imaging. In part I, there was greater and earlier reverse remodeling in the high restraint group. In both groups, the rate of reverse remodeling peaked and then declined as the measured restraint level decreased with progression of reverse remodeling. In part II, adjustable restraint resulted in greater reverse remodeling than standard restraint. Left ventricular end diastolic volume decreased by 12.7% (P = .005) with adjustable restraint and by 5.7% (P = .032) with standard restraint. Left ventricular ejection fraction increased by 18.9% (P = .014) and 14.4% (P < .001) with adjustable and standard restraint, respectively. Restraint level affects the rate and degree of reverse remodeling and is an important determinant of therapy efficacy. Adjustable restraint is more effective than nonadjustable restraint in promoting reverse remodeling. Copyright © 2013 The American Association for Thoracic Surgery. Published by Mosby, Inc.

Corticotropin-releasing factor (CRF) is expressed in the paraventricular nucleus of the hypothalamus (PVN), and act centrally to provoke stress-like autonomic and behavioral responses. Urocortins 1-3 are additional ligands to the CRF receptors 1 and 2. Ucn 1 neurons are primarily concentrated in the Edinger-Westphal (EW) nucleus and also have been associated with stress responses. It is also known that UCN 1 respond in different ways depending on the stressor presented. Benzodiazepines can act via the CRF peptidergic system and chronic administration of alprazolam does not interfere with CRF mRNA expression in the PVN, but significantly increase Ucn 1 mRNA expression in the EW. The aim of our study was to investigate the relationship between different stressor stimuli, foot shock (FS) and restraint (R), and the mRNA expression of CRF and Ucn 1 in the PVN and EW using alprazolam (A). We employed fos activation and in situ hybridization. Restraint group presented increased fos-ir and CRF mRNA expression in the PVN compared to FS group. The stress responses of R group were prevented by A. In the EW, fos-ir was higher in the FS group than in the R group, whereas Ucn 1 mRNA expression was higher in the R group than in the FS group. Alprazolam significantly increased fos-ir and Ucn 1 mRNA expression in both groups. Our results show that PVN and EW respond in different ways to the same stressors. Furthermore, EW of stressed animals replies in a complementary way comparing to PVN with the use of Alprazolam. Copyright © 2010 Elsevier Inc. All rights reserved.

Self-restraint is often reported in individuals with mental retardation who show self-injurious behavior (SIB). In this study, the phenomenology and prevalence of self-restraint in individuals showing self-injury and wearing protective devices and those showing self-injury but not wearing protective devices were compared. A high prevalence of self-restraint in the whole sample of individuals showing self-injury was identified (67/88, 76.1%), and self-restraint was more prevalent in a group showing self-injury but not wearing protective devices (43/47, 91.5%) than in a group showing self-injury and wearing protective devices (24/41, 58.5%). Individuals not wearing protective devices showed a greater number of topographies of self-restraint than those who did wear them. Results are discussed with reference to the purely topographical definition of self-restraint employed and the potential equivalence of protective devices and self-restraint.

The economic cost of using restraint and the value added by restraint reduction or elimination.

Lebel, Janice; Goldstein, Robert

2005-09-01

The purpose of this study was to calculate the economic cost of using restraint on one adolescent inpatient service and to examine the effect of an initiative to reduce or eliminate the use of restraint after it was implemented. A detailed process-task analysis of mechanical, physical, and medication-based restraint was conducted in accordance with state and federal restraint requirements. Facility restraint data were collected, verified, and analyzed. A model was developed to determine the cost and duration of an average episode for each type of restraint. Staff time allocated to restraint activities and medication costs were computed. Calculation of the cost of restraint was restricted to staff and medication costs. Aggregate costs of restraint use and staff-related costs for one full year before the restraint reduction initiative (FY 2000) and one full year after the initiative (FY 2003) were calculated. Outcome, discharge, and recidivism data were analyzed. A comparison of the FY 2000 data with the FY 2003 data showed that the adolescent inpatient service's aggregate use of restraint decreased from 3,991 episodes to 373 episodes (91 percent), which was associated with a reduction in the cost of restraint from $1,446,740 to $117,036 (a 92 percent reduction). In addition, sick time, staff turnover and replacement costs, workers' compensation, injuries to adolescents and staff, and recidivism decreased. Adolescent Global Assessment of Functioning scores at discharge significantly improved. Implementation of a restraint reduction initiative was associated with a reduction in the use of restraint, staff time devoted to restraint, and staff-related costs. This shift appears to have contributed to better outcomes for adolescents, fewer injuries to adolescents and staff, and lower staff turnover. The initiative may have enhanced adolescent treatment and work conditions for staff.

2001-08-01

The objective of this study was to estimate the use of restraint techniques and evaluate restraint policies and training in Australasian emergency departments A survey of 116 Australasian emergency departments was conducted to determine the type, indications/contraindications, training, policies, documentation and audit requirements for restraint. The overall estimated rate of patient restraint is 3.3 episodes per 1000 presentations. The commonest indications for restraint are violence or threatened violence (52%), psychosis (32%) and acute brain syndrome (10%). Major contraindications are medical instability, risk of harm to staff in applying restraint and the availability of alternatives to restraint. Chemical restraint is used in all emergency departments surveyed. The commonest agents used are haloperidol (93%), midazolam (82%) and diazepam (59%). At least one benzodiazepine and one major tranquilliser are used in 97% of emergency departments. Manual restraint (87%) is frequently used as a prelude to chemical or, less frequently, mechanical restraint (69%). Seclusion restraint is used in 23% of Australasian emergency departments. Formal training is most commonly undertaken for chemical restraint, being used in 33% of departments surveyed. Less than half of the departments have written policies guiding the use of restraint, and only 11% audit their use of restraint. A specific form for restraint documentation is used in only one emergency department. Patient restraint is a common procedure in Australasian emergency departments. There is little formal training in, or documentation or audit of, restraint practices in Australasian emergency departments, despite the important clinical, occupational health and medical legal issues associated with the use of restraint.

Electric foot shock stress adaptation: Does it exist or not?

PubMed

Bali, Anjana; Jaggi, Amteshwar Singh

2015-06-01

Stress adaptation is a protective phenomenon against repeated stress exposure and is characterized by a decreased responsiveness to a repeated stress stimulus. The adaptation is associated with a complex cascade of events, including the changes in behavior, neurotransmitter and gene expression levels. The non-adaptation or maladaptation to stress may underlie the affective disorders, such as anxiety, depression and post-traumatic stress disorder (PTSD). Electric foot shock is a complex stressor, which includes both physical and emotional components. Unlike immobilization, restraint and cold immersion stress, the phenomenon of stress adaptation is not very well defined in response to electric foot shock. A number of preclinical studies have reported the development of adaptation to electric foot shock stress. However, evidence also reveals the non-adaptive behavior in response to foot shocks. The distinct adaptive/non-adaptive responses may be possibly influenced by the type, intensity, and duration of the stress. The present review discusses the existence or non-existence of adaptation to electric foot shock stress along with possible mechanism. Copyright © 2015 Elsevier Inc. All rights reserved.

The Crew Equipment Translation Aid (CETA) experiment is an extravehicular activity (EVA) Space Transportation System (STS) based flight experiment which will explore various modes of transporting astronauts and light equipment for Space Station Freedom (SSF). The basic elements of CETA are: (1) two 25 foot long sections of monorail, which will be EVA assembled in the STS cargo bay to become a single 50 ft. rail called the track; (2) a wheeled baseplate called the truck which rolls along the track and can accept three cart concepts; and (3) the three carts which are designated manual, electric, and mechanical. The three carts serve as the astronaut restraint and locomotive interfaces with the track. The manual cart is powered by the astronaut grasping the track's handrail and pulling himself along. The electric cart is operated by an astronaut turning a generator which powers the electric motor and drives the cart. The mechanical cart is driven by a Bendix type transmission and is similar in concept to a man-propelled railroad cart. During launch and landing, the truck is attached to the deployable track by means of EVA removable restraint bolts and held in position by a system of retractable shims. These shims are positioned on the exterior of the rail for launch and landing and rotate out of the way for the duration of the experiment. The shims are held in position by strips of Velcro nap, which rub against the sides of the shim and exert a tailored force. The amount of force required to rotate the shims was a major EVA concern, along with operational repeatability and extreme temperature effects. The restraint system was tested in a thermal-vac and vibration environment and was shown to meet all of the initial design requirements. Using design inputs from the astronauts who will perform the EVA, CETA evolved through an iterative design process and represented a cooperative effort.

The heterogeneous array of software tools used in the process of protein NMR structure determination presents organizational challenges in the structure determination and validation processes, and creates a learning curve that limits the broader use of protein NMR in biology. These challenges, including accurate use of data in different data formats required by software carrying out similar tasks, continue to confound the efforts of novices and experts alike. These important issues need to be addressed robustly in order to standardize protein NMR structure determination and validation. PDBStat is a C/C++ computer program originally developed as a universal coordinate and protein NMR restraint converter. Its primary function is to provide a user-friendly tool for interconverting between protein coordinate and protein NMR restraint data formats. It also provides an integrated set of computational methods for protein NMR restraint analysis and structure quality assessment, relabeling of prochiral atoms with correct IUPAC names, as well as multiple methods for analysis of the consistency of atomic positions indicated by their convergence across a protein NMR ensemble. In this paper we provide a detailed description of the PDBStat software, and highlight some of its valuable computational capabilities. As an example, we demonstrate the use of the PDBStat restraint converter for restrained CS-Rosetta structure generation calculations, and compare the resulting protein NMR structure models with those generated from the same NMR restraint data using more traditional structure determination methods. These results demonstrate the value of a universal restraint converter in allowing the use of multiple structure generation methods with the same restraint data for consensus analysis of protein NMR structures and the underlying restraint data.

Repeated handling, restraint, or chronic crowding impair the hypothalamic-pituitary-adrenocortical response to acute restraint stress.

PubMed

Gadek-Michalska, A; Bugajski, J

2003-09-01

The purpose of the present study was to assess whether, and to what extent prior handling, restraint or social crowding stress during 3-10 days affects the hypothalamic-pituitary-adrenocortical (HPA) response to an acute short-lasting restraint stress. Also the effect of a feedback inhibitory mechanism of corticosterone in the impairment of HPA axis by these stressors was investigated. Male Wistar rats were pretreated with handling 1 min/day for 3-10 days, restraint 2 times daily for 3-7 days and crowding stress for 7 days before exposure to acute restraint stress in metal tubes for 10 min. Some group of rats received exogenous s.c. corticosterone either once 25 mg/kg or 2 times daily 10 mg/kg for 3-10 days before restraint stress. After the last restraint the rats were decapitated and their trunk blood was collected for the measurement of plasma ACTH and serum corticosterone levels. Handling for 3-7 days, restraint for 3-7 days, and crowding for 7 days and a single pretreatment with corticosterone--all significantly and to a similar extent inhibited the restraint stress-induced increase in ACTH and corticosterone secretion. Chronic pretreatment with corticosterone blunted the restraint stress-induced increase in HPA axis activity. These results indicate that repeated short-lasting stress induced by handling, restraint, or crowding potently attenuates the acute restraint stress-induced stimulatory action of the HPA axis. They also indicate adaptive action of moderate stress on the HPA axis response to acute stress. The results also suggest that a short-lasting hypersecretion of corticosterone during psychological stress may induce a prolonged feedback inhibition of the HPA axis activity. The attenuation of HPA axis response by prior handling has also obvious methodological implications.

Foot switches operating with force sensitive resistors placed in the shoe sole were considered as an effective way for driving FES assisted walking systems in gait restoration. However, the reliability and durability of the foot switches run down after a certain number of steps. As an alternative for foot switches, a simple, portable, and easy to handle motion driven electrical stimulator (ES) is provided for drop foot treatment. The device is equipped with a single tri-axis accelerometer worn on the pelvis, a commercial dual channel electrical stimulator, and a controller unit. By monitoring the pelvic rotation and acceleration during a walking cycle, the events including heel strike and toe off of each step is thereby predicted by a post-processing neural network model.

The objective of this study was to identify factors that predict restraint use and optimal restraint use among children aged 0 to 13 years. The data set is a national sample of police-reported crashes for years 2010-2014 in which type of child restraint is recorded. The data set was supplemented with demographic census data linked by driver ZIP code, as well as a score for the state child restraint law during the year of the crash relative to best practice recommendations for protecting child occupants. Analysis used linear regression techniques. The main predictor of unrestrained child occupants was the presence of an unrestrained driver. Among restrained children, children had 1.66 (95% confidence interval, 1.27, 2.17) times higher odds of using the recommended type of restraint system if the state law at the time of the crash included requirements based on best practice recommendations. Children are more likely to ride in the recommended type of child restraint when their state's child restraint law includes wording that follows best practice recommendations for child occupant protection. However, state child restraint law requirements do not influence when caregivers fail to use an occupant restraint for their child passengers.

A prototype Crew Medical Restraint System (CMRS) for Space Station Freedom

Johnston, S. L.; Eichstadt, F. T.; Billica, R. D.

1992-01-01

The Crew Medical Restrain System (CMRS) is a prototype system designed and developed for use as a universally deployable medical restraint/workstation on Space Station Freedom (SSF), the Shuttle Transportation System (STS), and the Assured Crew Rescue Vehicle (ACRV) for support of an ill or injured crewmember requiring stabilization and transportation to Earth. The CMRS will support all medical capabilities of the Health Maintenance Facility (HMF) by providing a restraint/interface system for all equipment (advance life support packs, defibrillator, ventilator, portable oxygen supply, IV pump, transport monitor, transport aspirator, and intervenous fluids delivery system) and personnel (patient and crew medical officers). It must be functional within the STS, ACRV, and all SSF habitable volumes. The CMRS will allow for medical capabilities within CPR, ACLS and ATLS standards of care. This must all be accomplished for a worst case transport time scenario of 24 hours from SSF to a definitive medical care facility on Earth. A presentation of the above design prototype with its subsequent one year SSF/HMF and STS/ACRV high fidelity mock-up ground based simulation testing will be given. Also, parabolic flight and underwater Weightless Test Facility evaluations will be demonstrated for various medical contingencies. The final design configuration to date will be discussed with future space program impact considerations.

Performing a surgical procedure during spaceflight will become more likely with longer duration missions in the near future. Minimal surgical capability has been present on previous missions as the definitive medical care time was short and the likelihood of surgical events too low to justify surgical hardware availability. Early demonstrations of surgical procedures in the weightlessness of parabolic flight indicated the need for careful logistical planning and restraint of surgical hardware. The consideration of human ergonomics also has more impact in weightlessness than in the conventionall-g environment. Three methods of surgical instrument restraint - a Minor Surgical Kit (MSK), a Surgical Restraint Scrub Suit (SRSS), and a Surgical Tray (ST) were evaluated in parabolic flight surgical procedures. The Minor Surgical Kit was easily stored, easily deployed, and demonstrated the best ability to facilitate a surgical procedure in weightlessness. Important factors in this surgical restraint system include excellent organization of supplies, ability to maintain sterility, accessibility while providing secure restraint, ability to dispose of sharp items and biological trash, and ergonomical efficiency.

Microgravity Workstation and Restraint Evaluations

Chmielewski, C.; Whitmore, M.; Mount, F.

1999-01-01

Confined workstations, where the operator has limited visibility and physical access to the work area, may cause prolonged periods of unnatural posture. Impacts on performance, in terms of fatigue and posture, may occur especially if the task is tedious and repetitive or requires static muscle loading. The glovebox design is a good example of the confined workstation concept. Within the scope of the 'Microgravity Workstation and Restraint Evaluation' project, funded by the NASA Headquarters Life Sciences Division, it was proposed to conduct a series of evaluations in ground, KC-135 and Shuttle environments to investigate the human factors issues concerning confined/unique workstations, such as gloveboxes, and also including crew restraint requirements. As part of the proposed integrated evaluations, two Shuttle Detailed Supplementary Objectives (DSOs) were manifested; one on Space Transportation System (STS)-90 and one on STS-88. The DSO on STS-90 evaluated use of the General Purpose Workstation (GPWS). The STS-88 mission was planned to evaluate a restraint system at the Remote Manipulator System (RMS). In addition, KC- 1 35 flights were conducted to investigate user/workstation/restraint integration for long-duration microgravity use. The scope of these evaluations included workstations and restraints to be utilized in the ISS environment, but also incorporated other workstations/ restraints in an attempt to provide findings/requirements with broader applications across multiple programs (e.g., Shuttle, ISS, and future Lunar-Mars programs). In addition, a comprehensive electronic questionnaire has been prepared and is under review by the Astronaut Office which will compile crewmembers' lessons learned information concerning glovebox and restraint use following their missions. These evaluations were intended to be complementary and were coordinated with hardware developers, users (crewmembers), and researchers. This report is intended to provide a summary of the

Restraint and the question of validity.

PubMed

Paterson, Brodie; Duxbury, Joy

2007-07-01

Restraint as an intervention in the management of acute mental distress has a long history that predates the existence of psychiatry. However, it remains a source of controversy with an ongoing debate as to its role. This article critically explores what to date has seemingly been only implicit in the debate surrounding the role of restraint: how should the concept of validity be interpreted when applied to restraint as an intervention? The practice of restraint in mental health is critically examined using two post-positivist constructions of validity, the pragmatic and the psychopolitical, by means of a critical examination of the literature. The current literature provides only weak support for the pragmatic validity of restraint as an intervention and no support to date for its psychopolitical validity. Judgements regarding the validity of any intervention that is coercive must include reference to the psychopolitical dimensions of both practice and policy.

Long-term, sustained progress is necessary in drop foot rehabilitation. The necessary inconvenient body training movements, the return trips to the hospital and repetitive boring training using functional electrical stimulation (FES) often results in the patient suspending their training. The patient's drop foot rehabilitation will not progress if training is suspended. A fast spread, highly portable drop foot rehabilitation training device based on the smart phone is presented. This device is combined with a self-made football APP and feedback controlled FES. The drop foot patient can easily engage in long term rehabilitation training that is more convenient and interesting. An interactive game is established on the smart phone with the Android system using the originally built-in wireless communications. The ankle angle information is detected by an external portable device as the game input signal. The electrical stimulation command to the external device is supplemented with FES stimulation for inadequate ankle efforts. After six-weeks training using six cases, the results indicated that this training device showed significant performance improvement (p< 0.05) in the patient's ankle dorsiflexion strength, ankle dorsiflexion angle, control timing and Timed Up and Go. Preliminary results show that this training device provides significant positive help to drop foot patients. Moreover, this device is based on existing and universally popular mobile processing, which can be rapidly promoted. The responses of clinical cases also show this system is easy to operate, convenient and entertaining. All of these features can improve the patient's willingness to engage in long term rehabilitation.

Manual restraint techniques are associated with the management of violence in psychiatric settings. Restraint effectiveness and acceptability are under scrutiny, yet the nature and frequency of who or what were involved in restraint episodes have not previously been fully described or understood. The aim of this study was to describe the nature and frequency of manual restraint-related events and their components. This study was carried out using content analyses of nurses' post-incident reports from a psychiatric unit situated within a general hospital, and from its associated medium-secure unit. Requests for restraint occurred at the rate of about once per day, and the majority related to patients' ill-directed frustration, resistance to containment and their desire to leave the ward. Only half of responses to conflicts resulted in restraint implementation. The majority of restraint activities occurred during the afternoon and night. Male patients and detained patients were more frequent participants in restraint interventions. To a lesser extent, police, ambulance, fire services, hospital security, visitors and ex-patients were also involved in restraint episodes. Injuries were rare. In conclusion, training in restraint skills, clinical audit of adverse incidents, and research into psychiatric aggression all need to take into account the association of restraint with the enforcement of detention and treatment of acutely ill patients. The coupling of restraint with medication requires examination of its safety and efficacy. Interagency training may enable the essential services involved to coordinate restraint activities more effectively.

An extension is proposed to the rigid-bond description of atomic thermal motion in crystals. The rigid-bond model [Hirshfeld (1976 ▶). Acta Cryst. A32, 239–244] states that the mean-square displacements of two atoms are equal in the direction of the bond joining them. This criterion is widely used for verification (as intended by Hirshfeld) and also as a restraint in structure refinement as suggested by Rollett [Crystallographic Computing (1970 ▶), edited by F. R. Ahmed et al., pp. 167–181. Copenhagen: Munksgaard]. By reformulating this condition, so that the relative motion of the two atoms is required to be perpendicular to themore » bond, the number of restraints that can be applied per anisotropic atom is increased from about one to about three. Application of this condition to 1,3-distances in addition to the 1,2-distances means that on average just over six restraints can be applied to the six anisotropic displacement parameters of each atom. This concept is tested against very high resolution data of a small peptide and employed as a restraint for protein refinement at more modest resolution (e.g. 1.7 Å)« less

Low speed vehicle passenger ejection restraint effectiveness.

PubMed

Seluga, Kristopher J; Ojalvo, Irving U; Obert, Richard M

2005-07-01

Current golf carts and LSV's (Low Speed Vehicles) produce a significant number of passenger ejections during sharp turns. These LSV's do not typically possess seatbelts, but do provide outboard bench seat hip restraints that also serve as handholds. However, many current restraint designs appear incapable of preventing passenger ejections due to their low height and inefficient handhold position. Alternative handhold and hip restraint designs may improve passenger safety. Accordingly, this paper examines minimum size requirements for hip restraints to prevent passenger ejection during sharp turns and evaluates the effectiveness of a handhold mounted at the center of the bench seat. In this study, a simulation of a turning cart supplies the dynamic input to a biomechanical model of an adult male seated in a golf cart. Various restraint combinations are considered, both with and without the central handhold, to determine the likelihood of passenger ejection. It is shown that only the largest restraint geometries prevent passenger ejection. Adequate hip restraints should be much larger than current designs and a central handhold should be provided. In this way, golf cart and LSV manufacturers could reduce passenger ejections and improve fleet safety by incorporating recommendations provided herein.

Vegetarianism, dietary restraint and feminist identity.

PubMed

Curtis, Morgan J; Comer, Lisa K

2006-05-01

Research examining the relationship between dietary restraint and vegetarianism has yielded inconsistent results due to differing definitions of vegetarianism and the possible modifying role of feminist identity. The current study sought to further clarify these relationships by examining three levels of vegetarianism, motivation for vegetarianism, and feminist identity (using an updated measure). Participants were 90 female undergraduate students and community members (mean age=24.34 years). Dietary restraint was measured using the TFEQ; feminism was assessed using the LFAIS. Weight-motivated semi-vegetarians reported higher levels of dietary restraint than those not motivated by weight. This effect did not appear among full-vegetarians. Lowest levels of dietary restraint were found among full-vegetarians with no difference between non- and semi-vegetarians. Contrary to previous research, feminist identity did not moderate the relationship between dietary restraint and vegetarianism. Limitations resulting from a scale with a narrow definition of feminism and the use of multiple sources of recruitment are discussed. Directions for future research are highlighted.

Evaluation of a Human Modeling Software Tool in the Prediction of Extra Vehicular Activity Tasks for an International Space Station Assembly Mission

Dischinger, H. Charles; Loughead, Tomas E.

The difficulty of accomplishing work in extravehicular activity (EVA) is well documented. It arises as a result of motion constraints imposed by a pressurized spacesuit in a near-vacuum and of the frictionless environment induced in microgravity. The appropriate placement of foot restraints is crucial to ensuring that astronauts can remove and drive bolts, mate and demate connectors, and actuate levers. The location on structural members of the foot restraint sockets, to which the portable foot restraint is attached, must provide for an orientation of the restraint that affords the astronaut adequate visual and reach envelopes. Previously, the initial location of these sockets was dependent upon the experienced designer's ability to estimate placement. The design was tested in a simulated zero-gravity environment; spacesuited astronauts performed the tasks with mockups while submerged in water. Crew evaluation of the tasks based on these designs often indicated the bolt or other structure to which force needed to be applied was not within an acceptable work envelope, resulting in redesign. The development of improved methods for location of crew aids prior to testing would result in savings to the design effort for EVA hardware. Such an effort to streamline EVA design is especially relevant to International Space Station construction and maintenance. Assembly operations alone are expected to require in excess of four hundred hours of EVA. Thus, techniques which conserve design resources for assembly missions can have significant impact. We describe an effort to implement a human modelling application in the design effort for an International Space Station Assembly Mission. On Assembly Flight 6A, the Canadian-built Space Station Remote Manipulator System will be delivered to the U.S. Laboratory. It will be released from its launch restraints by astronauts in EVA. The design of the placement of foot restraint sockets was carried out using the human model Jack, and

The red-footed booby ( Sula sula) is a widely distributed sulid native to the Galápagos archipelago. Hematology and blood chemistry parameters have been published for this species, but not from the San Cristóbal rookery. Analyses were run on blood samples drawn from 31 manually restrained red-footed boobies that were captured by hand from their nests at Punta Pitt on San Cristóbal Island. A portable blood analyzer (iSTAT) was used to obtain near immediate field results for pH, partial pressure of oxygen, partial pressure of carbon dioxide, bicarbonate, hematocrit, hemoglobin, sodium, potassium, ionized calcium, and glucose. Blood lactate was measured using a portable Lactate Plus™ analyzer. Average heart rate, respiratory rate, body weight, body temperature, and biochemistry and hematology parameters were comparable to those of healthy individuals of other sulids. The reported results provide baseline data that can be used for comparisons among populations and in detecting changes in health status among Galápagos red-footed boobies.

Introduction Foot disorders are common among older adults and may lead to outcomes such as falls and functional limitation. However, the associations of foot posture and foot function to specific foot disorders at the population level remain poorly understood. The purpose of this study was to assess the relation between specific foot disorders, foot posture, and foot function. Methods Participants were from the population-based Framingham Foot Study. Quintiles of the modified arch index and center of pressure excursion index from plantar pressure scans were used to create foot posture and function subgroups. Adjusted odds ratios of having each specific disorder were calculated for foot posture and function subgroups relative to a referent 3 quintiles. Results Pes planus foot posture was associated with increased odds of hammer toes and overlapping toes. Cavus foot posture was not associated with the foot disorders evaluated. Odds of having hallux valgus and overlapping toes were significantly increased in those with pronated foot function, while odds of hallux valgus and hallux rigidus were significantly decreased in those with supinated function. Conclusions Foot posture and foot function were associated with the presence of specific foot disorders. PMID:24040231

To determine the prevalence, types, frequency, and duration of restraint use in older adults receiving home nursing care and to determine factors involved in the decision-making process for restraint use and application. Cross-sectional survey of restraint use in older adults receiving home care completed by primary care nurses. Homes of older adults receiving care from a home nursing organization in Belgium. Randomized sample of older adults receiving home care (N = 6,397; mean age 80.6; 66.8% female). For each participant, nurses completed an investigator-constructed and -validated questionnaire collecting information demographic, clinical, and behavioral characteristics and aspects of restraint use. A broad definition of restraint was used that includes a range of restrictive actions. Restraints were used in 24.7% of the participants, mostly on a daily basis (85%) and often for a long period (54.5%, 24 h/d). The most common reason for restraint use was safety (50.2%). Other reasons were that the individual wanted to remain at home longer, which necessitated the use of restraints (18.2%) and to provide respite for the informal caregiver (8.6%). The latter played an important role in the decision and application process. The physician was less involved in the process. In 64.5% of cases, there was no evaluation after restraint use was initiated. Use of restraints is common in older adults receiving home care nursing in Belgium. These results contribute to a better understanding of the complexity of use of restraints in home care, a situation that may be even more complex than in nursing homes and acute hospital settings. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Positional asphyxia without active restraint following an assault.

Deaths due to positional asphyxia are most often accidental, associated with alcohol and/or drug intoxication. A 19-year-old male is reported who was assaulted and placed in a head-down position in the back of a car were he was later found dead. Brush abrasions indicated that he had been dragged to the vehicle. The head and right shoulder were wedged into the foot well with the body uppermost. At autopsy, there was marked congestion of the face, neck, and upper chest with conjunctival ecchymoses, bruising of the face and scalp, focal subarachnoid hemorrhage, minor cerebral contusion, and diffuse cerebral swelling with early hypoxic ischemic encephalopathy (HIE). Toxicology was negative. Death was attributed to HIE resulting from the unusual positioning of the body. Cases of positional asphyxia involving others may not always include restraint, and when encountered should initiate a careful evaluation of the possible events and lethal pathophysiological processes. © 2013 American Academy of Forensic Sciences.

Williamson, Donald A.; Martin, Corby K.; York-Crowe, Emily; Anton, Stephen D.; Redman, Leanne M.; Han, Hongmei; Ravussin, Eric

2007-01-01

This study tested the validity of four measures of dietary restraint: Dutch Eating Behavior Questionnaire, Eating Inventory (EI), Revised Restraint Scale (RS), and the Current Dieting Questionnaire. Dietary restraint has been implicated as a determinant of overeating and binge eating. Conflicting findings have been attributed to different methods for measuring dietary restraint. The validity of four self-report measures of dietary restraint and dieting behavior was tested using: 1) factor analysis, 2) changes in dietary restraint in a randomized controlled trial of different methods to achieve calorie restriction, and 3) correlation of changes in dietary restraint with an objective measure of energy balance, calculated from the changes in fat mass and fat-free mass over a six-month dietary intervention. Scores from all four questionnaires, measured at baseline, formed a dietary restraint factor, but the RS also loaded on a binge eating factor. Based on change scores, the EI Restraint scale was the only measure that correlated significantly with energy balance expressed as a percentage of energy require d for weight maintenance. These findings suggest that that, of the four questionnaires tested, the EI Restraint scale was the most valid measure of the intent to diet and actual caloric restriction. PMID:17101191

International Space Station Crew Restraint Design

Whitmore, M.; Norris, L.; Holden, K.

2005-01-01

With permanent human presence onboard the International Space Station (ISS), crews will be living and working in microgravity, dealing with the challenges of a weightless environment. In addition, the confined nature of the spacecraft environment results in ergonomic challenges such as limited visibility and access to the activity areas, as well as prolonged periods of unnatural postures. Without optimum restraints, crewmembers may be handicapped for performing some of the on-orbit tasks. Currently, many of the tasks on ISS are performed with the crew restrained merely by hooking their arms or toes around handrails to steady themselves. This is adequate for some tasks, but not all. There have been some reports of discomfort/calluses on the top of the toes. In addition, this type of restraint is simply insufficient for tasks that require a large degree of stability. Glovebox design is a good example of a confined workstation concept requiring stability for successful use. They are widely used in industry, university, and government laboratories, as well as in the space environment, and are known to cause postural limitations and visual restrictions. Although there are numerous guidelines pertaining to ventilation, seals, and glove attachment, most of the data have been gathered in a 1-g environment, or are from studies that were conducted prior to the early 1980 s. Little is known about how best to restrain a crewmember using a glovebox in microgravity. In 2004, The Usability Testing and Analysis Facility (UTAF) at the NASA Johnson Space Center completed development/evaluation of several design concepts for crew restraints to meet the various needs outlined above. Restraints were designed for general purpose use, for teleoperation (Robonaut) and for use with the Life Sciences Glovebox. All design efforts followed a human factors engineering design lifecycle, beginning with identification of requirements followed by an iterative prototype/test cycle. Anthropometric

Child safety restraints are effective measures in protecting children from an injury while traveling in a car. However, the rate of child restraint use is extremely low in Chinese cities. Parent drivers could play an important role in promoting child safety restraint use, but not all of them take active responsibility. This study used a qualitative approach and included 14 in-depth interviews among parents with a child, under the age of 6, living in Shantou City (7 child safety restraint users and 7 non-users). Purposive sampling was used to recruit eligible parent drivers who participated in a previous observation study. Interview data were collected from March to April 2013. The audio taped and transcribed data were coded and analyzed to identify key themes. Four key themes on child safety restraint emerged from the in-depth interviews with parents. These included 1) Having a child safety restraint installed in the rear seat with an adult sitting next to the restrained child is ideal, and child safety restraint is seen as an alternative when adult accompaniment is not available; 2) Having effective parental education strategies could help make a difference in child safety restraint use; 3) Inadequate promotion and parents' poor safety awareness contribute to the low rate of child safety restraint in China; 4) Mandatory legislation on child safety restraint use could be an effective approach. Inadequate promotion and low awareness of safe traveling by parents were closely linked to low child safety seat usage under the circumstance of no mandatory legislation. Future intervention efforts need to focus on increasing parents' safe travel awareness combined with CSS product promotion before the laws are enacted.

The wobble board enables a therapy strategy for rehabilitation of the ankle foot complex. Quantification of therapy, such as through the use of a wobble board, can facilitate a therapist's acuity for advancing and optimizing the overall therapy strategy. The portable media device, such as an iPod, can be equipped with a software application to function as a wireless gyroscope platform. Integration of the wobble board with the portable media device functioning as a wireless gyroscope enables the potential for patient to therapist interaction through connectivity to the Internet. A patient can conduct wobble board therapy for the ankle foot complex from the convenient vantage point of a homebound setting with therapy data transmitted wirelessly as email attachments. The gyroscope signal of the wobble board therapy can be consolidated into a feature set for machine learning classification. Using a multilayer perceptron neural network considerable classification accuracy has been achieved for differentiating between a hemiplegic affected ankle and unaffected ankle while using a wobble board. The combination of machine learning, wireless systems, such as a portable media device functioning as a wireless gyroscope, and a conventional therapy device, such as a wobble board, are envisioned to advance the capability to optimally impact the rehabilitation experience.

Nurses' perceptions and practice of physical restraint in China.

There is controversy concerning the use of physical restraint. Despite this controversy, some nurses still consider the application of physical restraint unavoidable for some of their clients. Identify the perceptions and practice of physical restraint in China. This was a descriptive study that combined qualitative interviews with a quantitative cross-sectional survey. A total of 18 nurses were interviewed and 330 nurses were surveyed. Approval of the study was obtained from the hospital ethics committee. Permission to conduct the study was obtained from the director of nursing. Participants were assured that their participation is voluntary. Physical restraint was commonly used to protect patients' safety. Naturally, intensive care unit nurses used physical restraint much more frequently than general medical/surgical ward nurses (p < 0.01). In addition, night shift nurses tended to use physical restraint more frequently. Nursing managers should be aware of the role nurses play in the use of physical restraint. In-service training regarding the proper use of physical restraint should be strengthened and nurse staffing levels should be improved in order to minimize the use of physical restraint in China. © The Author(s) 2014.

With permanent human presence onboard the International Space Station (ISS), a crew will be living and working in microgravity, interfacing with their physical environment. Without optimum restraints and mobility aids (R&MA' s), the crewmembers may be handicapped for perfonning some of the on-orbit tasks. In addition to weightlessness, the confined nature of a spacecraft environment results in ergonomic challenges such as limited visibility and access to the activity area and may cause prolonged periods of unnatural postures. Thus, determining the right set of human factors requirements and providing an ergonomically designed environment are crucial to astronauts' well-being and productivity. The purpose of this project is to develop requirements and guidelines, and conceptual designs, for an ergonomically designed multi-purpose crew restraint. In order to achieve this goal, the project would involve development of functional and human factors requirements, design concept prototype development, analytical and computer modeling evaluations of concepts, two sets of micro gravity evaluations and preparation of an implementation plan. It is anticipated that developing functional and design requirements for a multi-purpose restraint would facilitate development of ergonomically designed restraints to accommodate the off-nominal but repetitive tasks, and minimize the performance degradation due to lack of optimum setup for onboard task performance. In addition, development of an ergonomically designed restraint concept prototype would allow verification and validation of the requirements defined. To date, we have identified "unique" tasks and areas of need, determine characteristics of "ideal" restraints, and solicit ideas for restraint and mobility aid concepts. Focus group meetings with representatives from training, safety, crew, human factors, engineering, payload developers, and analog environment representatives were key to assist in the development of a restraint

Current ventricular restraint devices do not allow for either the measurement or adjustment of ventricular restraint level. Periodic adjustment of restraint level post-device implantation may improve therapeutic efficacy. We evaluated the feasibility of an adjustable quantitative ventricular restraint (QVR) technique utilizing a fluid-filled polyurethane epicardial balloon to measure and adjust restraint level post-implantation guided by physiologic parameters. QVR balloons were implanted in nine ovine with post-infarction dilated heart failure. Restraint level was defined by the maximum restraint pressure applied by the balloon to the epicardium at end-diastole. An access line connected the balloon lumen to a subcutaneous portacath to allow percutaneous access. Restraint level was adjusted while left ventricular (LV) end-diastolic volume (EDV) and cardiac output was assessed with simultaneous transthoracic echocardiography. All nine ovine successfully underwent QVR balloon implantation. Post-implantation, restraint level could be measured percutaneously in real-time and dynamically adjusted by instillation and withdrawal of fluid from the balloon lumen. Using simultaneous echocardiography, restraint level could be adjusted based on LV EDV and cardiac output. After QVR therapy for 21 days, LV EDV decreased from 133+/-15 ml to 113+/-17 ml (p<0.05). QVR permits real-time measurement and physiologic adjustment of ventricular restraint therapy after device implantation.

We investigated the characteristics of multiple episodes of mechanical restraint versus a single episode in a psychiatric ward of a public general hospital. The following characteristics were associated with multiple restraints: young age, length of hospital stay, not being readmitted within 30 days from previous discharge, and admission in the previous year before the implementation of an intervention program to reduce mechanical restraint. The study suggests that both organizational factors and patients' disturbed behaviour are associated with the risk of being mechanically restrained several times.

Motor vehicle crashes are the leading cause of death for U.S. Latinos aged 1 to 35 years. Restraint use is an effective means of prevention of motor vehicle crash injury. Effective interventions to raise restraint use include the following: legislation, law enforcement, education, and equipment distribution. The effects of law enforcement interventions in Latino immigrant communities are understudied. We measured the community-level effect of a combined intervention that included warnings and citations phase enforcement in Latino communities. We designed and implemented in two of three Latino-majority communities a multicomponent intervention consisting of a community awareness campaign, restraint use education with equipment distribution, and a two-staged law enforcement intervention. Restraint use observations were conducted in all three communities at baseline, after the warnings phase and again after the citations phase of the intervention were completed. The combined intervention of community awareness, education, child passenger restraint distribution, and law enforcement focused on educational traffic stops with incentives and warnings was associated with a significant increase in both driver and child passenger restraint use in one intervention community, but only driver restraint increased to a level of significance in the other intervention community; significant increase was also noted among nonintervention drivers. The citations phase of the intervention did not result in a significant increase in restraint use and was complicated by interruptions due to unlicensed drivers. The combined effort of community awareness, education, equipment distribution and law enforcement intervention that included incentives and warnings may be effective at increasing seat belt use in Latino communities without the need for citations.

Relatively high rates of child restraint inappropriate use and misuse and faults in the installation of restraints have suggested a crucial need for public education messages to raise parental awareness of the need to use restraints correctly. This project involved the devising and pilot testing of message concepts, filming of a television advertisement (the TVC), and the evaluation of the TVC. This article focuses specifically upon the evaluation of the TVC. The development and evaluation of the TVC were guided by an extended theory of planned behavior that included the standard constructs of attitudes, subjective norms, and perceived behavioral control as well as the additional constructs of group norms and descriptive norms. The study also explored the extent to which parents with low and high intentions to self-check restraints differed on salient beliefs regarding the behavior. An online survey of parents (N = 384) was conducted where parents were randomly assigned to either the intervention group (n = 161), and therefore viewed the advertisement within the survey, or the control group (n = 223), and therefore did not view the advertisement. Following a one-off exposure to the TVC, the results indicated that, although not a significant difference, parents in the intervention group reported stronger intentions (M = 4.43, SD = 0.74) to self-check restraints than parents in the control group (M = 4.18, SD = 0.86). In addition, parents in the intervention group (M = 4.59, SD = 0.47) reported significantly higher levels of perceived behavioral control than parents in the control group (M = 4.40, SD = 0.73). The regression results revealed that, for parents in the intervention group, attitudes and group norms were significant predictors of parental intentions to self-check their child restraint. Finally, the exploratory analyses of parental beliefs suggested that those parents with low intentions to self-check child restraints were significantly more likely than

Physical restraint: perceptions of nurse managers, registered nurses and healthcare assistants.

To examine the perceptions of nurse managers, registered nurses and healthcare assistants of physical restraint use on older people in a long-term care setting in the Republic of Ireland. The use of physical restraint, although controversial, persists in long-term care settings, despite recommendations for restraint-free environments. Perception and attitude of staff can influence use of physical restraint. A descriptive cross-sectional design was used. A total of 250 nursing and healthcare assistant staff were recruited. A questionnaire incorporating demographics and the Perceptions of Restraint Use Questionnaire was used. Descriptive and inferential statistical analyses were conducted. Mean age of respondents (n = 156) was 41 years, and the majority were female. Overall, a low level of importance was attached to the use of restraint. Nurse managers and registered nurses compared favourably with healthcare assistants who attached a higher importance to use of restraint. Across all three staff groups, greatest importance was attached to the use of physical restraint for reducing falls, followed by prevention of treatment interference. Restraint was least favoured as a means of impairment management. Education was not an explanatory factor in perceived importance of physical restraint use. Nurse managers and registered nurses are unlikely to use physical restraint. However, there is concern regarding perception of healthcare assistants on use of restraint. Results from this study compare favourably with those in countries that have no policy on physical restraint use. Educational programmes alone are insufficient to address use of physical restraint. Attention to skill mix with adequate support for healthcare assistants in long-term care settings is recommended. © 2018 International Council of Nurses.

2018-03-01

To get insight into restraint use in older adults receiving home care and, more specifically, into the definition, prevalence and types of restraint, as well as the reasons for restraint use and the people involved in the decision-making process. Systematic review. Four databases (i.e. Pubmed, CINAHL, Embase, Cochrane Library) were systematically searched from inception to end of April 2017. The study encompassed qualitative and quantitative research on restraint use in older adults receiving home care that reported definitions of restraint, prevalence of use, types of restraint, reasons for use or the people involved. We considered publications written in English, French, Dutch and German. One reviewer performed the search and made the initial selection based on titles and abstracts. The final selection was made by two reviewers working independently; they also assessed study quality. We used an integrated design to synthesise the findings. Eight studies were reviewed (one qualitative, seven quantitative) ranging in quality from moderate to high. The review indicated there was no single, clear definition of restraint. The prevalence of restraint use ranged from 5% to 24.7%, with various types of restraint being used. Families played an important role in the decision-making process and application of restraints; general practitioners were less involved. Specific reasons, other than safety for using restraints in home care were noted (e.g. delay to nursing home admission; to provide respite for an informal caregiver). Contrary to the current socio demographical evolutions resulting in an increasing demand of restraint use in home care, research on this subject is still scarce and recent. The limited evidence however points to the challenging complexity and specificity of home care regarding restraint use. Given these serious challenges for clinical practice, more research about restraint use in home care is urgently needed. Copyright © 2017. Published by Elsevier

Visalli, H; McNasser, G

2000-07-01

The Mohawk Valley Psychiatric Center has experienced a major reduction in the use of seclusion and restraint in the past five years. It has used the traditional quality improvement (QI) tools like the Plan Do Check Act, Flowcharts, Fishbone diagrams, and Parieto Charts as suggested in the QI literature. The original work to reduce seclusion and restraint are described in two previous articles by Visalli and McNasser. This article describes the additional work since that time. The seclusion/restraint rate in adult service per 1,000 patient days is 0.13 for restraint and 0.15 for seclusion for calendar year 1998. Children and youth service also has comparatively minimal use of seclusion and restraint. The success of this program is attributed to the organizational leadership and the interdisciplinary approach taken to provide individualized treatment. Many of the initiatives stem from a working relationship with patients on how to improve customer service.

Moderation: an alternative to restraint as a mode of weight self-regulation.

PubMed

Stotland, S

2012-12-01

This study considered two types of eating and weight self-regulation, in five groups, including four types of weight controllers and one non-dieting group. New scales were developed to measure eating moderation and restraint. Moderation was largely uncorrelated with restraint in 4 groups and had a fairly strong positive relation in 1 group. The moderation scale was unrelated to the Dutch Eating Behavior Questionnaire (DEBQ) restraint scale and the Three Factor Eating Questionnaire (TFEQ) rigid restraint subscale and weakly positively related to TFEQ flexible restraint. The restraint scale was strongly correlated to the DEBQ restraint scale, and to both flexible and rigid restraint subscales of the TFEQ. Across the five groups, moderation had exclusively positive relationships with attitude, behavior and emotion variables, while restraint had primarily negative relationships. The study supports moderation as a new dimension of weight self-regulation, independent of restraint. The new measures of moderation and restraint can be used together in research on the processes of change in weight management. Copyright © 2012 Elsevier Ltd. All rights reserved.

2013-12-01

Restraint of older persons in inpatient and residential care is used to control aggression, and prevent falls and other adverse outcomes. Initiatives to reduce these practices are being implemented worldwide. However, there has been little examination of restraint practice in psychiatric services for older persons. This paper reports a retrospective comparative analysis of restraint use in three acute and two extended care psychiatric inpatient wards in Australia. The analysis involved examination of restraint incidents and comparison of restrained and non-restrained patients. There was significant variation in restraint use between wards. On one acute ward, 12.74% of patients were restrained, although restraint use declined during the data collection period. Patients with dementia were restrained at higher rates than patients with other diagnoses, and restrained patients stayed in hospital for a longer duration. Restraint occurred early in admission, and few differences emerged between those restrained once or multiple times. Mechanical restraint was more prevalent than physical restraint, with restraint predominantly used to manage aggression and falls. Findings provide new data on restraint in older persons' psychiatric services. Greater conceptual understandings of behaviours associated with dementia and the unique needs of patients with these disorders may assist in reducing restraint use in these settings. © 2012 The Authors; International Journal of Mental Health Nursing © 2012 Australian College of Mental Health Nurses Inc.

1994-04-01

To reduce physical restraint use in a nursing home and increase employee support for the restraint-reduction program. A one-group pretest-posttest design with repeated measures was used to determine changes in restraint use with participants over a 14-month interval. All individuals employed at the nursing home were surveyed at two time periods to determine their opinions on restraint use. A 265-bed private, non-profit nursing home in Dallas, Texas. A restrained cohort of 170 residents with a mean age of 84 years; 84% were female. A total of 182 employees participated in the first survey and 209 in the second. Formation of a project team that planned and supervised restraint removal. Inservice training on restraint use was conducted for all employees. Type and frequency of restraint use among the restrained cohort at four evaluation points within a 14-month interval. The frequency of restraint use in the nursing home population was also recorded. Survey measures included employee responses to a 16-item closed-end questionnaire before and after training. The mean number of restraints used with each resident in the restrained cohort decreased from 1.56 to 0.67. The number of residents on restraints in the nursing home was reduced during the course of the study (67.5% vs. 36.7%, P < 0.0001). Changes in employee opinions about restraint use were found after training. On the second survey, more than twice as many employees indicated that restraints should be removed from almost all residents who have them (15.2% vs 36.3%, P < 0.0001). A restraint-reduction program in a nursing home can produce positive results in terms of decreased restraint use and supportive employee attitudes. More practical alternatives to restraints need to be developed for application in the training of nursing home employees. Future studies on resident, employee, and family attitudes about restraint use are suggested.

To examine changes in child car restraint practices in low socioeconomic areas following the introduction of mandatory child car restraint legislation in New South Wales (NSW), Australia. Data from two cross-sectional studies of child car restraint use at pre-schools, early childhood centres and primary schools before and after the introduction of legislating mandatory age-appropriate car restraint use for children up to the age of seven years was used in this analysis. All included observations were from local government areas with socioeconomic status in the lowest 30% of urban Sydney. Children aged 2-5 years were observed in their vehicles as they arrived at observation sites (107 pre-legislation, 360 post-legislation). Multilevel logistic regression was used to examine changes in observed age-appropriate and correct use of car restraints. Age-appropriate car restraint use was higher post-legislation than pre-legislation. After controlling for child's age, parental income, language spoken at home and adjusting for clustering, the odds of children being appropriately restrained post-legislation were 2.3 times higher than in the pre-legislation sample, and the odds of them being correctly restrained were 1.6 times greater. Results indicate an improvement in car restraint practices among children aged 2-5 in low socioeconomic areas after introduction of child restraint laws. Implications : Despite improvements observed with enhanced legislation, further efforts are required to increase optimal child car restraint use. © 2013 The Authors.

Planus Foot Posture and Pronated Foot Function are Associated with Foot Pain: The Framingham Foot Study

PubMed Central

Menz, Hylton B.; Dufour, Alyssa B.; Riskowski, Jody L.; Hillstrom, Howard J.; Hannan, Marian T.

2014-01-01

Objective To examine the associations of foot posture and foot function to foot pain. Methods Data were collected on 3,378 members of the Framingham Study who completed foot examinations in 2002–2008. Foot pain (generalized and at six locations) was based on the response to the question “On most days, do you have pain, aching or stiffness in either foot?” Foot posture was categorized as normal, planus or cavus using static pressure measurements of the arch index. Foot function was categorized as normal, pronated or supinated using the center of pressure excursion index from dynamic pressure measurements. Sex-specific multivariate logistic regression models were used to examine the effect of foot posture and function on generalized and location-specific foot pain, adjusting for age and weight. Results Planus foot posture was significantly associated with an increased likelihood of arch pain in men (odds ratio [OR] 1.38, 95% confidence interval [CI] 1.01 – 1.90), while cavus foot posture was protective against ball of foot pain (OR 0.74, 95% CI 0.55 – 1.00) and arch pain (OR 0.64, 95% CI 0.48 – 0.85) in women. Pronated foot function was significantly associated with an increased likelihood of generalized foot pain (OR 1.28, 95% CI 1.04 – 1.56) and heel pain (OR 1.54, 95% CI 1.04 – 2.27) in men, while supinated foot function was protective against hindfoot pain in women (OR 0.74, 95% CI 0.55 – 1.00). Conclusion Planus foot posture and pronated foot function are associated with foot symptoms. Interventions that modify abnormal foot posture and function may therefore have a role in the prevention and treatment of foot pain. PMID:23861176

2018-03-01

The practice of mechanically restraining psychiatric patients is constantly under debate, and staff attitudes are considered a central factor influencing restraining practices. The aim of this study was to explore associations between psychiatric staff members' presence and participation in incidences of restraint and attitudes towards mechanical restraints. Staff members (psychiatrists, nurses, paramedical staff; N = 143 working in a government psychiatric hospital in Israel) completed a questionnaire including personal information, participation in incidents of restraint and attitudes towards mechanical restraints. Items were categorized into the following categories: security and care; humiliation and offending; control; order; education and punishment. Compared to those who were not present during restraint, staff members who were present agreed significantly less with statements indicating that restraints are humiliating and offending and agreed more with statements indicating that restraints are used primarily for security and care (p < .05). Among those present in incidences of restraint, staff members who physically participated in restraint agreed significantly more with statements indicating that restraints are a means for security, care and order, and less with statements indicating restraints are humiliating and offending, compared to those present but not physically participating in restraint (p < .05). These findings highlight the importance of proximity of staff members to incidences of restraints. This may have implications in understanding the professional and social discourse concerning mechanical restraints.

Improvements in structural biology methods, in particular crystallography and cryo-electron microscopy, have created an increased demand for the refinement of atomic models against low-resolution experimental data. One way to compensate for the lack of high-resolution experimental data is to use a priori information about model geometry that can be utilized in refinement in the form of stereochemical restraints or constraints. Here, the definition and calculation of the restraints that can be imposed on planar atomic groups, in particular the angle between such groups, are described. Detailed derivations of the restraint targets and their gradients are provided so that they canmore » be readily implemented in other contexts.

Optimizations of Human Restraint Systems for Short-Period Acceleration

NASA Technical Reports Server (NTRS)

Payne, P. R.

1963-01-01

A restraint system's main function is to restrain its occupant when his vehicle is subjected to acceleration. If the restraint system is rigid and well-fitting (to eliminate slack) then it will transmit the vehicle acceleration to its occupant without modifying it in any way. Few present-day restraint systems are stiff enough to give this one-to-one transmission characteristic, and depending upon their dynamic characteristics and the nature of the vehicle's acceleration-time history, they will either magnify or attenuate the acceleration. Obviously an optimum restraint system will give maximum attenuation of an input acceleration. In the general case of an arbitrary acceleration input, a computer must be used to determine the optimum dynamic characteristics for the restraint system. Analytical solutions can be obtained for certain simple cases, however, and these cases are considered in this paper, after the concept of dynamic models of the human body is introduced. The paper concludes with a description of an analog computer specially developed for the Air Force to handle completely general mechanical restraint optimization programs of this type, where the acceleration input may be any arbitrary function of time.

Legislating child restraint usage -Its effect on self-reported child restraint use rates in a central city.

2010-02-01

To assess the effect of the newly enacted child passenger safety law, Wisconsin Act 106, on self-report of proper restraint usage of children in Milwaukee's central city population. A prospective, non-randomized study design was used. The settings used were (a) a pediatric urban health center, and (b) two Women, Infants and Children offices in Milwaukee, Wisconsin. Participants included 11,566 surveys collected over 18 months that spanned the pre-legislation and post-legislation time periods from February 2006 through August 2008. The study set out to assess appropriate child passenger restraint. The results showed that the changes in adjusted proper restraint usage rates for infants between the pre-law, grace period, and post-fine periods were 94%, 94%, and 94% respectively. For children 1-3years old, the adjusted proper usage rates were 65%, 63%, and 59%, respectively. And for children 4-7years old, the rates were 43%, 44% and 42%, respectively. There was a significant increase in premature booster seat use in children who should have been restrained in a rear- or forward-facing car seat (10% pre-law, 12% grace period, 20% post-fine; p<0.0005). There was no statistically significant change over time in unrestrained children (2.1%, 1.7%, 1.7%, p=0.7, respectively). The passage of a strengthened child passenger safety law with fines did not significantly improve appropriate restraint use for 0-7year olds, and appropriate use in 1-7year olds remained suboptimal with a majority of urban children inappropriately restrained. Although the number of unrestrained children decreased, we identified an unintended consequence of the legislation - a significant increase in the rate of premature belt-positioning booster seat use among poor, urban children. The design of child restraint systems maximizes protection of the child. Increasing reports of misuse is a call to those who manufacture these child passenger restraints to improve advertising and marketing to the correct age

Safety and efficacy of physical restraints for the elderly. Review of the evidence.

PubMed Central

Frank, C.; Hodgetts, G.; Puxty, J.

1996-01-01

OBJECTIVE: To critically review evidence on the safety and efficacy of physical restraints for the elderly and to provide family physicians with guidelines for rational use of restraints. DATA SOURCES: Articles cited on MEDLINE (from 1989 to November 1994) and Cinahl (from 1982 to 1994) under the MeSH heading "physical restraints." STUDY SELECTION: Articles that specifically dealt with the safety and efficacy of restraints and current patterns of use, including prevalence, risk factors, and indications, were selected. Eight original research articles were identified and critically appraised. DATA EXTRACTION: Data extracted concerned the negative sequelae of restraints and the association between restraint use and fall and injury rates. General data about current patterns of restraint use were related to safety and efficacy findings. DATA SYNTHESIS: No randomized, controlled trials of physical restraint use were found in the literature. A variety of study design, including retrospective chart review, prospective cohort studies, and case reports, found little evidence that restraints prevent injury. Some evidence suggested that restraints might increase risk of falls and injury. Restraint-reduction programs have not been shown to increase fall or injury rates. Numerous case reports document injuries or deaths resulting from restraint use or misuse. CONCLUSIONS: Although current evidence does not support the belief that restraints prevent falls and injuries and questions their safety, further prospective and controlled studies are needed to clarify these issues. Information from review and research articles was synthesized in this paper to produce guidelines for the safe and rational use of restraints. PMID:8969858

Use of physical restraint in nursing homes: clinical‐ethical considerations

PubMed Central

Gastmans, C; Milisen, K

2006-01-01

This article gives a brief overview of the state of the art concerning physical restraint use among older persons in nursing homes. Within this context we identify some essential values and norms that must be observed in an ethical evaluation of physical restraint. These values and norms provide the ethical foundation for a number of concrete recommendations that could give clinical and ethical support to caregivers when they make decisions about physical restraint. Respect for the autonomy and overall wellbeing of older persons, a proportional assessment of the advantages and disadvantages, a priority focus on the alternatives to physical restraint, individualised care, interdisciplinary decision making, and an institutional policy are the central points that make it possible to deal responsibly with the use of physical restraint for older persons in nursing homes.

Backbone-only restraints for fast determination of the protein fold: The role of paramagnetism-based restraints. Cytochrome b562 as an example

NASA Astrophysics Data System (ADS)

Banci, Lucia; Bertini, Ivano; Felli, Isabella C.; Sarrou, Josephine

2005-02-01

CH α residual dipolar couplings (Δ rdc's) were measured for the oxidized cytochrome b562 from Escherichia coli as a result of its partial self-orientation in high magnetic fields due to the anisotropy of the overall magnetic susceptibility tensor. Both the low spin iron (III) heme and the four-helix bundle fold contribute to the magnetic anisotropy tensor. CH α Δ rdc's, which span a larger range than the analogous NH values (already available in the literature) sample large space variations at variance with NH Δ rdc's, which are largely isooriented within α helices. The whole structure is now significantly refined with the chemical shift index and CH α Δ rdc's. The latter are particularly useful also in defining the molecular magnetic anisotropy parameters. It is shown here that the backbone folding can be conveniently and accurately determined using backbone restraints only, which include NOEs, hydrogen bonds, residual dipolar couplings, pseudocontact shifts, and chemical shift index. All these restraints are easily and quickly determined from the backbone assignment. The calculated backbone structure is comparable to that obtained by using also side chain restraint. Furthermore, the structure obtained with backbone only restraints is, in its whole, very similar to that obtained with the complete set of restraints. The paramagnetism based restraints are shown to be absolutely relevant, especially for Δ rdc's.

In mice, previously, we showed that restraint stress reduces the number of embryo implantation sites in the endometrium. Here, we hypothesized that the uterine microenvironment is altered by restraint stress and consequently is suboptimal for embryo implantation. On embryonic day 1 (E1), 60 of 154 pregnant CD1 mice underwent restraint stress (4 h), repeated daily to E3, E5 or E7 (n = 10 mice per group). Restraint stress decreased food intake and suppressed body weight gain on E3, E5 and E7. Restraint stress decreased the actual and relative weight (percent body weight) of uterus and ovary on E5 (by 14.9%, p = 0.03; 16.1%, p = 0.004) and E7 (by 16.8%, p = 0.03; 20.0%, p = 0.01). Morphologically, restraint stress decreased relative endometrial area (by 8.94-18.8%, p = 0.003-0.021) and uterine gland area (by 30.6%, p < 0.01 on E3 and 44.5%, p < 0.01 on E5). Immunohistochemistry showed that restraint stress decreased microvessel density (by 12.9-70.5%, p < 0.01) and vascular endothelial growth factor expression (by 14.6-45.9%, p = 0.007-0.02). Restraint stress decreased by 32.4-39.8% (p = 0.002-0.01) the mean optical density ratio for proliferating cell nuclear antigen/terminal deoxynucleotidyl transferase dUTP nick end labeling. Methyl thiazolyl tetrazolium assay showed a dose-dependent decrease in proliferative activity of endometrial stromal cells (from 52 of 154 pregnant E5 control mice) incubated with H2O2 (100-1000 μM) in vitro. These findings supported the hypothesis that restraint stress negatively influences endometrial adaptive remodeling via an oxidative stress pathway, which resulted in fewer implantation sites.

IIHS head restraint ratings and insurance injury claim rates.

PubMed

Trempel, Rebecca E; Zuby, David S; Edwards, Marcy A

2016-08-17

The Insurance Institute for Highway Safety (IIHS) rates front seat/head restraint designs using a combination of static and dynamic measurements following RCAR-IIWPG procedures. The purpose of this study was to determine whether vehicles with better IIHS-rated seats/head restraints had lower injury risk in rear-end collisions and how the effect of better rated seats interacted with driver gender and age. The presence of an associated insurance injury claim was determined for rear-impact crashes using 2001-2014 model year cars and SUVs. Logistic regression was used to compare injury risk for vehicles with good, acceptable, and marginal IIHS-rated seats/head restraints with poor-rated seats/head restraints. Analyses were run by gender and driver age and also by the rate of more severe injury claims. Injury rates were 11.2% lower for vehicles with seats/head restraints rated good compared to vehicles with seats/head restraints rated poor. The percentage reduction for good- versus poor-rated seats was greater for females (12.7%) than males (8.9%). Comparing good- with poor-rated seats, driver ages 15-24 had the largest reduction at 19.8%, followed by 10.7% for driver ages 45-64 and 10.4% for driver ages 25-44. Seats/head restraints with better IIHS ratings are associated with lower injury rates in rear-impact collisions than seats rated poor. The reductions in injury rates were strongest for females and for young-to-middle-age drivers. The strong reductions in injury rates for these groups are encouraging given their high initial injury rates.

Background Although foot pain has been linked to fall risk, contributions of pain severity, foot posture or foot function are unclear. These factors were examined in a cohort of older adults. Objective The purpose of this study was to examine the associations of foot pain, severity of foot pain and measures of foot posture and dynamic foot function with reported falls in a large, well-described cohort of older adults from the Framingham Foot Study. Methods Foot pain, posture and function were collected from Framingham Foot Study participants who were queried about falls over the past year (0, 1, 2+ falls). Logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CI) for the relation of falls with foot pain, pain severity, foot posture, and foot function adjusting for covariates. Results Of 1375 participants, mean age was 69y; 57% were female; 21% reported foot pain (40% mild pain, 47% moderate, 13% severe pain). One-third reported falls in past year (1 fall: n=263, 2+ falls: n=152). Foot pain was associated with a 62% increased odds of recurrent falls. Those with moderate and severe foot pain showed increased odds of 2+ falls (OR=1.78, CI 1.06–2.99, and OR = 3.25, CI 1.65–7.48, respectively) compared to no foot pain. Foot function was not associated with falls. Compared to normal foot posture, those with planus foot posture had 78% higher odds of 2+ falls. Conclusion Higher odds of recurrent falls were observed in individuals with foot pain, especially severe foot pain, as well as individuals with planus foot posture, indicating that both foot pain and foot posture may play a role in increasing the risk of falls among older adults.

Serotonin (5-HT) modulates the hypothalamic-pituitary-adrenal (HPA) axis response to stress. We examined the effect of chronic restraint stress (CRS; 20 min/day) as compared to control (CTRL) conditions for 14 days, on: 1) restraint-induced ACTH and corticosterone (CORT) secretion in rats pretreated with vehicle or SB-656104 (a 5-HT7 receptor antagonist); 2) 5-HT7 receptor-like immunoreactivity (5-HT7-LI) and protein in the hypothalamic paraventricular nucleus (PVN) and adrenal glands (AG); 3) baseline levels of 5-HT and 5-hydroxyindolacetic acid (5-HIAA), and 5-HIAA/5-HT ratio in PVN and AG; and 4) 5-HT-like immunoreactivity (5-HT-LI) in AG and tryptophan hydroxylase (TPH) protein in PVN and AG. On day 15, animals were subdivided into Treatment and No treatment groups. Treatment animals received an i.p. injection of vehicle or SB-656104; No Treatment animals received no injection. Sixty min later, Treatment animals were either decapitated with no further stress (0 min) or submitted to acute restraint (10, 30, 60 or 120 min); hormone serum levels were measured. No Treatment animals were employed for the rest of measurements. CRS decreased body weight gain and increased adrenal weight. In CTRL animals, acute restraint increased ACTH and CORT secretion in a time of restraint-dependent manner; both responses were inhibited by SB-656104. Exposure to CRS abolished ACTH but magnified CORT responses to restraint as compared to CTRL conditions; SB-656104 had no effect on ACTH levels but significantly inhibited sensitized CORT responses. In CTRL animals, 5-HT7-LI was detected in magnocellular and parvocellular subdivisions of PVN and sparsely in adrenal cortex. Exposure to CRS decreased 5-HT7-LI and protein in the PVN, but increased 5-HT7-LI in the adrenal cortex and protein in whole AG. Higher 5-HT and 5-HIAA levels were detected in PVN and AG from CRS animals but 5-HIAA/5-HT ratio increased in AG only. Finally, whereas 5-HT-LI was sparsely observed in the adrenal cortex

The objective of this research was to describe the use and incorrect use of child restraint systems in Manitoba, Canada. In 2004, a team of inspectors made up of Royal Canadian Mounted Police officers and trained car seat technicians from the Manitoba child seat coalition conducted a descriptive survey of types and frequency of child restraint systems' incorrect use. The setting was 10 roadside inspection sites located around the city of Winnipeg, Manitoba. The subjects were parents and primary caregivers of children using child restraint systems. The main outcome measured was the reported appropriate use rate as determined by the compliance to safety standards for correct installation and use of child restraints. A total of 340 child restraint systems were assessed. The overall rate of incorrect use was 70%. The errors present in stage III systems (booster seats) are much lower than the errors present in stage I systems (rear-facing child safety seats) and stage II systems (forward-facing child safety seats). The data presented illustrate that incorrect use of child restraint systems in the province of Manitoba is a large problem and must be dealt with immediately in order to ensure child safety now and in the future. Community-wide information and enhanced enforcement campaigns, consisting of activities such as mass media, information and publicity, child restraint systems displays and special enforcement strategies (check points, dedicated law enforcement officials, alternative penalties) should be used to increase the correct use of child restraint systems. Failure to use child restraint systems properly can contribute to serious injury or death of a child.

Anxiolytic-like effects of restraint during the dark cycle in adolescent mice.

Stress during developmental stage may cause psychological morbidities, and then the studies on stress are important in adolescent rodents. Restraint is used as a common stressor in rodents and the effects of restraint during the light cycle have been studied, but those of restraint during the dark cycle have not. The present study examined the effects of restraint during the light and dark cycles on anxiety behaviors in adolescent mice. Restraint for 3h during either the light or dark cycle impaired memory function in the fear conditioning test, but did not affect locomotor activity. In the elevated plus-maze test, restraint during the dark cycle reduced anxiety-like behaviors in mice. Repeated exposure to a 3-h period dark cycle restraint for 2 weeks had a similar anxiolytic-like effect. In contrast, restraint for 3h during the light cycle produced anxiety behavior in adolescent, but not adult, mice. The light cycle stress increased plasma corticosterone levels, and elevated c-Fos expression in the prefrontal cortex, paraventricular hypothalamic nucleus, basolateral amygdala and dentate gyrus, and enhanced serotonin turnover in the hippocampus and striatum, while the dark cycle stress did not. There was no difference in the stress-mediated reduction in pentobarbital-induced sleeping time between dark and light cycle restraint. These findings suggest that the anxiolytic effect of dark cycle restraint is mediated by corticosterone, serotonin or γ-aminobutyric acid-independent mechanisms, although the anxiogenic effect of light cycle restraint is associated with changes in plasma corticosterone levels and serotonin turnover in specific brain regions.

To investigate the knowledge, attitude, intention and practice of nurses towards physical restraint and factors influencing these variables. A literature review showed a lack of studies focused on the intention of nurses regarding physical restraint throughout the world. Considering that very little research on physical restraint use has been carried out in Malaysia, assessment of nurses' knowledge, attitude, intention and practice is necessary before developing a minimising programme in hospitals. A cross-sectional study was used. A questionnaire to assess the knowledge, attitude, intention and practice was completed by all nurses (n = 309) in twelve wards of a teaching hospital in Kuala Lumpur. Moderate knowledge and attitude with strong intention to use physical restraint were found among the nurses. Less than half of nurses considered alternatives to physical restraint and most of them did not understand the reasons for the physical restraint. Nurses' academic qualification, read any information source during past year and nurses' work unit showed a significant association with nurses' knowledge. Multiple linear regression analysis found knowledge, attitude and intention were significantly associated with nurses' practice to use physical restraint. This study showed some important misunderstandings of nurses about using physical restraint and strong intention regarding using physical restraint. Findings of this study serve as a supporting reason for importance of educating nurses about the use of physical restraint. Exploring the knowledge, attitude, intention and current practice of nurses towards physical restraint is important so that an effective strategy can be formulated to minimise the use of physical restraints in hospitals. © 2017 John Wiley & Sons Ltd.

Vehicle interior interactions and kinematics of rear facing child restraints in frontal crashes.

PubMed

Sherwood, C P; Gopalan, S; Abdelilah, Y; Marshall, R J; Crandall, J R

2005-01-01

The performance of rear facing child restraints in frontal crashes can be determined by controlling a) the child's kinematics and b) interactions with vehicle structures. Twelve sled tests were performed to analyze the effect of the location and structural properties of vehicle interior components. The role of restraint kinematics was studied by developing computational models which underwent idealized motions. Stiff structures originally offset from the restraint, but which contact the restraint late in the test, cause increased injury values. Attachment methods which reduce child restraint rotation and more rigidly couple the restraint to the vehicle result in the best safety performance.

Geometry of rear seats and child restraints compared to child anthropometry.

Bilston, Lynne E; Sagar, Nipun

2007-10-01

The objective of this study was to evaluate the geometry of a wide range of restraints (child restraints, booster seats and rear seats) used by children, and how these match their anthropometry, and to determine limitations to restraint size for the population of children using them. The study is motivated by the widespread premature graduation from one restraint type to another, which parents often attribute to children outgrowing their previous restraint. Currently, recommended transitions are based on a small sample of vehicles and children. Outboard rear seat and seat belt geometry (anchorage locations, sash belt angles) from 50 current model vehicles were measured using a custom-developed measuring jig. For 17 child restraints, a 3-dimensional measuring arm was used to measure the geometry of the restraint including interior size and strap slot locations (where relevant). These measurements were compared to anthropometric measurements, to determine the suitability of a given restraint for children of particular ages. The results for the rear seat geometry indicate that all seat cushions were too deep for a child whose upper leg length is at the 50th percentile until approximately 11.5 years, and half of vehicle seat cushions were too deep for a 15 year old child whose upper leg length is at the 50th percentile. Sash belt geometry was more variable, with approximately a third of vehicles accommodating 6-8 year olds who approximate the shoulder geometry measurements at the 50th percentile. Dedicated child restraints accommodated most children within recommended age groups, with two exceptions. Several high back booster seats were not tall enough for a child whose seated height is at the 50th percentile for 8 year olds (who is still too short for an adult belt according to current guidelines and the results from the rear seat geometry study), and a small number of forward facing restraints and high back boosters were too narrow for children at the upper end of

2015-01-01

Physical and pharmacological restraints are a controversial issue in the context of geriatric care due to their moral, ethical, social and legal repercussions and, despite this fact, no specific legislation exists at a national level. The use of restraints is being questioned with growing frequency, as there are studies that demonstrate that restraints do not reduce the number of falls or their consequences, but rather can increase them, cause complications, injuries and potentially fatal accidents. Restraints are not always used rationally, despite compromising a fundamental human right, that is, freedom, protected in the Constitution, as well as values and principles, such as dignity and personal self-esteem. There are centers where restraints are applied to more than 50% of patients, and in some cases without the consent of their legal representatives. On some occasions, restraints are used for attaining organizational or environmental objectives, such as complying with tight schedules, and for reducing or avoiding the supervision of patients who walk erratically and, at times, are used indefinitely. Even greater confusion exists with respect to the emerging concept of chemical or pharmacological restraints, since no conceptual framework exists based on scientific evidence, and with sufficient consensus for guiding healthcare workers. In this context, the Sociedad Española de Geriatría y Gerontología (SEGG--Spanish Geriatrics and Gerontology Society), aware of the significance and transcendence of the issue, and in an attempt to preserve and guarantee maximum freedom, dignity and self-esteem, on the one hand, and to ensure the maximum integrity and legal certainty of the persons cared for in geriatric and gerontology services and centers, on the other, decided to create an "Interdisciplinary Committee on Restraints" made up by members from different disciplines and members of SEGG Working Groups or Committees, external health care workers, groups

Despite the reported harms and ethical concerns about physical restraint use in the critical care settings, nurses' intention to apply them is unequal across countries. According to the theory of planned behaviour, eliciting nurses' beliefs regarding the use of physical restraints would provide additional social information about nurses' intention to perform this practice. To explore the salient behavioural, normative and control beliefs underlying the intention of critical care nurses to use physical restraints from the theory of planned behaviour. A belief elicitation study was conducted. Participants and research context: Twenty-six critical care nurses were purposively sampled across gender, work-shift patterns and professional experience in five intensive care units of three hospitals in Spain. Data were obtained from a nine-item open-ended questionnaire and a focus group. Deductive content analysis was performed. Ethical considerations: Ethical approval was obtained from the hospital ethics committee. Participants were assured their participation was voluntary. Nurses framed the use of restraints as a way of prioritising patients' physical safety. They referred to contextual factors as the main reasons to justify their application. Nurses perceived that their decision is approved by other colleagues and the patients' relatives. Some nurses started advocating against their use, but felt powerless to change this unsafe practice within an unfavourable climate. Control beliefs were linked to patients' medical condition, availability of alternative solutions, analgo-sedation policies and work organisation. Safety arguments based on the surrounding work environment were discussed. Nurses' behavioural and control beliefs were related. Nurses should be trained in alternatives to physical restraint use. The impact of analgo-sedation protocols, relatives' involvement, leadership support and intensive care unit restraint policies on physical restraint practices need to

Airbags & children: making correct choices in child passenger restraints.

Countless numbers of young lives are lost each year due to motor vehicle crashes. One of the most effective means of reducing the number of children killed and injured as occupants in motor vehicles is through the use of child passenger restraints. Seat belts and child safety seats save lives and reduce the severity of injuries sustained by occupants in motor vehicle crashes. Nurses are in a unique position to educate and influence families on the proper way to safely transport all motor vehicle passengers. Therefore, nurses working with infants, children, and families have a moral and professional obligation to understand the basics of child passenger safety. At the very least, nurses should be able to direct families appropriately for specifics related to child passenger restraints. The intent of this article is to provide an overview of child passenger safety through a historical, theoretical, and clinical approach. Proper child restraint use is reviewed based on current recommendations for age and size. The potential hazards of child restraint misuse, with an in-depth discussion on airbags, is presented. The discussion on airbags serves to dispel any misconceptions that may be held about airbags. The article includes two case studies that illustrate the injury potential of relatively common misuse patterns. The clinical implications for maternal-child nurses include the recognition that child passenger deaths are primarily due to child restraint nonuse and misuse and the realization of nursing's role in the promotion of proper child passenger restraint.

Male Wistar rats were starved for 12 hr and then subjected to either 2 hr of wire mesh "envelope" restraint at room temperature; 2 hr of supine restraint in a specially constructed harness at room temperature or were not restrained. Eight brain regions were examined for NA level and the level of its major metabolite, MHPG-SO4. Plasma corticosterone and gastric ulcer incidence were also measured. All restrained rats displayed marked elevations in MHPG-SO4 levels in most brain regions. In addition, several brain regions in restrained animals showed a reduction in NA level. All restrained rats showed elevated plasma corticosterone levels and evidence of gastric lesions. In general, supine restraint produced greater alterations in regional brain NA turnover, greater evidence of ulcer disease, and higher plasma corticosterone levels than did wire mesh restraint. These data suggest that acute but intense stress in the form of restraint causes markedly altered brain NA activity--a possible neurochemical mechanism underlying the phenomenon of stress-induced disease.

Quantifying the relationship between vehicle interior geometry and child restraint systems.

The prevention of interactions of children or child restraints with other vehicle structures is critical to child passenger safety. Fifteen current vehicles and seven rear and forward facing child restraint systems were measured in an attempt to quantify the available distance between child restraints and these vehicle structures. Rear facing child restraints exhibited such small amounts of clearance that contact would be expected in the majority of frontal crashes. Upper tethers are critical in the prevention of head contact, while head contact is likely when the upper tether is not used.

Human sensory systems are limited in many different regards, yet they are great sources of inspiration for development of technologies that help humans to overcome their restraints. This paper signifies the capability of our developed electronic nose in rapid lard identification. The developed device, known as E-Nose, mimics human’s olfactory system’s technique to identify a particular substance. Lard is a common pig derivative which is often used as a food additive, emulsion or shortening. It’s also commonly used as an adulterant or as an alternative for cooking oils, margarine and butter. This substance is prohibited to be consumed by Muslims and Orthodox Jews for religious reasons. A portable reliable device with an ability to identify lard rapidly can be convenient to users concerned about lard adulteration. The prototype was examined using K-Nearest Neighbors algorithm (KNN), Support Vector Machine (SVM), Bagged Trees and Simple Tree, and can identify lard with the highest accuracy of 95.6% among three types of fat (lard, chicken and beef) in liquid form over a certain range of temperature using KNN.

Di Lorenzo, Rosaria; Baraldi, Sara; Ferrara, Maria; Mimmi, Stefano; Rigatelli, Marco

2012-04-01

To analyze physical restraint use in an Italian acute psychiatric ward, where mechanical restraint by belt is highly discouraged but allowed. Data were retrospectively collected from medical and nursing charts, from January 1, 2005, to December 31, 2008. Physical restraint rate and relationships between restraints and selected variables were statistically analyzed. Restraints were statistically significantly more frequent in compulsory or voluntary admissions of patients with an altered state of consciousness, at night, to control aggressive behavior, and in patients with "Schizophrenia and other Psychotic Disorders" during the first 72 hr of hospitalization. Analysis of clinical and organizational factors conditioning restraints may limit its use. © 2011 Wiley Periodicals, Inc.

Vehicle Interior Interactions and Kinematics of Rear Facing Child Restraints in Frontal Crashes

PubMed Central

Sherwood, C. P.; Gopalan, S.; Abdelilah, Y.; Marshall, R. J.; Crandall, J. R.

2005-01-01

The performance of rear facing child restraints in frontal crashes can be determined by controlling a) the child’s kinematics and b) interactions with vehicle structures. Twelve sled tests were performed to analyze the effect of the location and structural properties of vehicle interior components. The role of restraint kinematics was studied by developing computational models which underwent idealized motions. Stiff structures originally offset from the restraint, but which contact the restraint late in the test, cause increased injury values. Attachment methods which reduce child restraint rotation and more rigidly couple the restraint to the vehicle result in the best safety performance. PMID:16179150

Environmental restraints and life strategies: a habitat templet matrix.

Holm, E

1988-02-01

Four basic environmental restraints on life are deduced from the requirements of life's inherent order laws. Possible life strategies to contend with these restraints are listed. The various combinations of the restraints are subsequently investigated, and appropriate combinations of life strategies are fitted. This model is finally tested against insect case histories in various environments, and is demonstrated to explain some combinations of characteristics of insects in ecosystems not covered by the r-K or r-K-A continua. The role of heterochrony in achieving appropriate life strategies is briefly discussed.

Torsional Restraint Problem of Steel Cold-Formed Beams Restrained By Planar Members

NASA Astrophysics Data System (ADS)

Balázs, Ivan; Melcher, Jindřich; Pešek, Ondřej

2017-10-01

The effect of continuous or discrete lateral and torsional restraints of metal thinwalled members along their spans can positively influence their buckling resistance and thus contribute to more economical structural design. The prevention of displacement and rotation of the cross-section results in stabilization of the member. The restraints can practically be provided e.g. by planar members of cladding supported by metal members (purlins, girts). The rate of stabilization of a member can be quantified using values of shear and rotational stiffness provided by the adjacent planar members. While the lateral restraint effected by certain shear stiffness can be often considered as sufficient, the complete torsional restraint can be safely considered in some practical cases only. Otherwise the values of the appropriate rotational stiffness provided by adjacent planar members may not be satisfactory to ensure full torsional restraint and only incomplete restraint is available. Its verification should be performed using theoretical and experimental analyses. The paper focuses on problem of steel thin-walled coldformed beams stabilized by planar members and investigates the effect of the magnitude of the rotational stiffness provided by the planar members on the resistance of the steel members. Cold-formed steel beams supporting planar members of cladding are considered. Full lateral restraint and incomplete torsional restraint are assumed. Numerical analyses performed using a finite element method software indicate considerable influence of the torsional restraint on the buckling resistance of a steel thin-walled member. Utilization of the torsional restraint in the frame of sizing of a stabilized beam can result in more efficient structural design. The paper quantifies this effect for some selected cases and summarizes results of numerical analysis.

Behavioral and physiological adaptation to repeated chair restraint in rhesus macaques.

Ruys, J D; Mendoza, S P; Capitanio, J P; Mason, W A

Physical restraint is a commonly used procedure when working closely with nonhuman primates. Nonhuman primates show rapid behavioral changes when learning the restraint procedure, and these changes have been taken to reflect behavioral and physiological habituation to the procedure. This study examined the behavioral and adrenocortical responses to repeated physical restraint in a large sample of adult male rhesus monkeys. Subjects showed a decline in behavioral agitation and cortisol concentrations across seven consecutive days of restraint. The changes in adrenocortical responsiveness were also coincident with an increased sensitivity to dexamethasone and a change in early morning basal cortisol secretion. The subjects were restrained for a single session 6 months later, and while the reduction in behavioral agitation was still present, the majority of changes in adrenocortical responsiveness were no longer present. These data show that behavior is not necessarily an indicator of underlying physiological processes and that the reduction of hypothalamic-pituitary-adrenal (HPA) activity with repeated restraint is due to physiological adaptation to high glucocorticoid concentrations and not to psychological habituation to the restraint procedures.

Lateral restraint assembly for reactor core

DOEpatents

Gorholt, Wilhelm; Luci, Raymond K.

1986-01-01

A restraint assembly for use in restraining lateral movement of a reactor core relative to a reactor vessel wherein a plurality of restraint assemblies are interposed between the reactor core and the reactor vessel in circumferentially spaced relation about the core. Each lateral restraint assembly includes a face plate urged against the outer periphery of the core by a plurality of compression springs which enable radial preloading of outer reflector blocks about the core and resist low-level lateral motion of the core. A fixed radial key member cooperates with each face plate in a manner enabling vertical movement of the face plate relative to the key member but restraining movement of the face plate transverse to the key member in a plane transverse to the center axis of the core. In this manner, the key members which have their axes transverse to or subtending acute angles with the direction of a high energy force tending to move the core laterally relative to the reactor vessel restrain such lateral movement.

Ensemble models of proteins and protein domains based on distance distribution restraints.

PubMed

Jeschke, Gunnar

2016-04-01

Conformational ensembles of intrinsically disordered peptide chains are not fully determined by experimental observations. Uncertainty due to lack of experimental restraints and due to intrinsic disorder can be distinguished if distance distributions restraints are available. Such restraints can be obtained from pulsed dipolar electron paramagnetic resonance (EPR) spectroscopy applied to pairs of spin labels. Here, we introduce a Monte Carlo approach for generating conformational ensembles that are consistent with a set of distance distribution restraints, backbone dihedral angle statistics in known protein structures, and optionally, secondary structure propensities or membrane immersion depths. The approach is tested with simulated restraints for a terminal and an internal loop and for a protein with 69 residues by using sets of sparse restraints for underlying well-defined conformations and for published ensembles of a premolten globule-like and a coil-like intrinsically disordered protein. © 2016 Wiley Periodicals, Inc.

Behavioral Effects of Acclimatization To Restraint Protocol Used for Awake Animal Imaging

PubMed Central

Reed, Michael D.; Pira, Ashley S.; Febo, Marcelo

2013-01-01

Functional MRI of awake rats involves acclimatization to restraint to minimize motion. We designed a study to examine the effects of an acclimatization protocol (5 days of restraint, 60 minutes per day) on the emission of 22-kHz ultrasonic vocalizations and performance on a forced swim test (FST). Our results show that USV calls are reduced significantly by day 3, 4 and 5 of acclimatization. Although rats show less climbing activity (and more immobility) in FST on day 5 compared to the 1st day of restraint acclimatization, the difference is gone once animals are given a 2 week hiatus. Overall, we show that animals adapt to the restraint over the five day period, however, restraint may introduce confounding behavioral outcomes that may hinder the interpretation of results derived from awake rat imaging. The present data warrant further testing of the effects of MRI restraint on behavior. PMID:23562621

2013-01-01

Objective. Abnormal foot posture and function have been proposed as possible risk factors for low back pain, but this has not been examined in detail. The objective of this study was to explore the associations of foot posture and foot function with low back pain in 1930 members of the Framingham Study (2002–05). Methods. Low back pain, aching or stiffness on most days was documented on a body chart. Foot posture was categorized as normal, planus or cavus using static weight-bearing measurements of the arch index. Foot function was categorized as normal, pronated or supinated using the centre of pressure excursion index derived from dynamic foot pressure measurements. Sex-specific multivariate logistic regression models were used to examine the associations of foot posture, foot function and asymmetry with low back pain, adjusting for confounding variables. Results. Foot posture showed no association with low back pain. However, pronated foot function was associated with low back pain in women [odds ratio (OR) = 1.51, 95% CI 1.1, 2.07, P = 0.011] and this remained significant after adjusting for age, weight, smoking and depressive symptoms (OR = 1.48, 95% CI 1.07, 2.05, P = 0.018). Conclusion. These findings suggest that pronated foot function may contribute to low back symptoms in women. Interventions that modify foot function, such as orthoses, may therefore have a role in the prevention and treatment of low back pain. PMID:24049103

Observations of child travel were made in Knoxville and Nashville, Tennessee, and Lexington and Louisville, Kentucky about two and one-half years after the Tennessee child restraint law went into force. Use of child restraints anchored by seat belts increased in Tennessee from 8 per cent prior to the law to 29 per cent, compared to a change from 11 to 14 per cent in Kentucky, which does not have a child restraint law. Travel in arms, a hazardous practice permitted by the law, was at the same level in Tennessee and Kentucky as prior to passage of the law. PMID:7457685

Do head-restraints protect the neck from whiplash injuries?

1989-01-01

Over an 11-month period a study was made of all patients presenting to an accident and emergency department who had sustained whiplash as a result of rear-bumper impacts. The patients were analysed with respect to the presence of head-restraints in their vehicles. A significant increase in the incidence of whiplash was found in patients whose vehicles did not have head-restraints fitted. Legislation requiring all passenger cars to have head-restraints fitted as standard would have a major impact in reducing the number of whiplash injuries sustained in rear bumper impacts.

The use of physical and pharmacological restraint is controversial but is currently accepted as inevitable. It is indicated for controlling behavioral disorders and psychomotor agitation that put patients and third parties at risk. Its indication should be medical, and we should opt for the least restrictive measure. Restraints represent a possible infringement of patients' fundamental rights and require understanding and strict respect for the medical-legal precepts by physicians and other practitioners involved in its application. This article reviews the current legal framework, as well as the medical-legal premises and aspects of applying restraints, with the objective of ensuring maximum respect for patients' rights and the appropriate legal safety in the activity of practitioners.

2008-08-01

The application of foot anthropometry to design good-fitting footwear has been difficult due to the lack of generalised models. This study seeks to model foot dimensions so that the characteristic shapes of feet, especially in the midfoot region, can be understood. Fifty Hong Kong Chinese adults (26 males and 24 females) participated in this study. Their foot lengths, foot widths, ball girths and foot heights were measured and then evaluated using mathematical models. The results showed that there were no significant allometry (p > 0.05) effects of foot length on ball girth and foot width. Foot height showed no direct relationship with foot length. However, a normalisation with respect to foot length and foot height resulted in a significant relationship for both males and females with R(2) greater than 0.97. Due to the lack of a direct relationship between foot height and foot length, the current practice of grading shoes with a constant increase in height or proportionate scaling in response to foot length is less than ideal. The results when validated with other populations can be a significant way forward in the design of footwear that has an improved fit in the height dimension.

The Indian Mental Health Care Act 2017 (MHCA -2017) advocates the duty to provide treatment in the least coercive manner. Little data exists on how Indian patients perceive coercion in medical settings. To study the prevalence of restraint in a Indian psychiatric inpatient unit, and to examine the level of perceived coercion correlating to various forms of restraint. This is a hospital based prospective observational study. Two hundred patients were recruited through computer generated random number sampling. In eligible subjects, demographic and clinical data, restraints used and assessments related to perceived coercion were completed within 3 days of admission. Perceived coercion was reassessed at the time or within 3 days before discharge. In 66.5% one or more restraint measures were used, physical restraints in 20%, chemical restraints in 58%, seclusion in 18%, and involuntary medication in 32%. ECT is associated with the lowest level of perceived coercion followed by isolation/seclusion, chemical restraint, involuntary medication and physical restraint. Male gender, being married, rural background, low socioeconomic status, having a mood disorder, and alcohol or drug dependence was associated with an increased risk of physical or chemical restraint. Having a mood disorder, being from a rural area and a lower socioeconomic status was associated with being subjected to more than one form of coercion. Restraint measures are more prevalent in psychiatric hospital care in India than in Europe. Physical restraint is particularly associted with higher perceived coercion. Copyright © 2018 Elsevier B.V.

Hagedorn, Thomas J.; Dufour, Alyssa B.; Hannan, Marian T.

2015-01-01

Background. Specific regions of the foot are responsible for the gait tasks of weight acceptance, single-limb support, and forward propulsion. With region foot pain, gait abnormalities may arise and affect the plantar pressure and force pattern utilized. Therefore, this study’s purpose was to evaluate plantar pressure and force pattern differences between adults with and without region-specific foot pain. Methods. Plantar pressure and force data were collected on Framingham Foot Study members while walking barefoot at a self-selected pace. Foot pain was evaluated by self-report and grouped by foot region (toe, forefoot, midfoot, or rearfoot) or regions (two or three or more regions) of pain. Unadjusted and adjusted linear regression with generalized estimating equations was used to determine associations between feet with and without foot pain. Results. Individuals with distal foot (forefoot or toes) pain had similar maximum vertical forces under the pain region, while those with proximal foot (rearfoot or midfoot) pain had different maximum vertical forces compared to those without regional foot pain (referent). During walking, there were significant differences in plantar loading and propulsion ranging from 2% to 4% between those with and without regional foot pain. Significant differences in normalized maximum vertical force and plantar pressure ranged from 5.3% to 12.4% and 3.4% to 24.1%, respectively, between those with and without regional foot pain. Conclusions. Associations of regional foot pain with plantar pressure and force were different by regions of pain. Region-specific foot pain was not uniformly associated with an increase or decrease in loading and pressure patterns regions of pain. PMID:25995291

When responders are dealing with an agitated patient in the field, safety for all involved may sometimes only be accomplished with physical or chemical restraints. While experiences using chemical restraint in the prehospital setting are found in the medical literature, the use of this by law enforcement as a first-response restraint has not previously been described. We report a case of successful law enforcement-administered sedation of a noncommunicative, autistic, and violent minor using intramuscular droperidol and diphenhydramine. Although this case has some unique characteristics that allowed chemical restraint to be given by the law enforcement agency, it calls attention to some specific prehospital issues that need to be addressed when dealing with autistic patients with extreme agitation.

Occupant restraint in the rear seat: ATD responses to standard and pre-tensioning, force-limiting belt restraints.

2008-10-01

Recent studies have shown that restrained occupants over the age of 50 in frontal crashes have a higher risk of injury in the rear seat than in the front, and have hypothesized that the incorporation of technology such as belt pre-tensioning and force limiting preferentially in the front seat is at least partially responsible for this trend. This study investigates the potential benefits and trade-offs of seat belt pretensioners and force-limiters in the rear seat using a series of frontal impact sled tests at two speeds (48 km/h and 29 km/h DeltaV) with a buck representing the interior of the reat seat occupant compartment of a contemporary mid-sized sedan. Four different dummies were tested: the Hybrid III six year old (in a booster seat, H3 6YO), the Hybrid III 5(th) percentile female (H3 AF05), the Hybrid III 50(th) percentile male (H3 AM50), and the THOR-NT. The restraints consisted of either a standard three point belt, or a 3-point belt with a retractor pretensioner and a progressive force-limiter (FL+PT). Each test condition was repeated in triplicate. The FL+PT restraints (compared to the standard restraints) resulted in a significant (p < or = 0.05) decrease in peak internal chest deflection for each of the Hybrid III dummies at both test speeds (48 km/h: 29% decrease for H3 6YO, 38% decrease for H3 AF05, 30% decrease for H3 AM50), and for the THOR-NT at a DeltaV of 29 km/h. At 48 km/h, the FL+PT restraint qualitatively decreased the average peak internal chest deflection of the THOR-NT, however this decrease was not statistically significant (p=0.06). Furthermore, the FL+PT system allowed little or no increase in forward head excursion, and improved whole-body kinematics for all dummies by restricting pelvic excursion and slightly increasing torso pitch. The results suggest that the FL+PT system studied here may provide injury-reducing benefit to rear seat occupants in moderate to high severity frontal crashes, although more study is needed to evaluate

We retrospectively reviewed medical records, nursing logs and quality assurance data for all adult patient encounters in a PES over a 12-month period (June 1, 2011-May 31, 2012). Descriptors included demographic characteristics, diagnoses, laboratory values, and clinician ratings of symptom severity. χ(2) and multivariate logistic regression analyses were performed. Restraint/seclusion occurred in 14% of 5335 patient encounters. The following characteristics were associated with restraint/seclusion: arrival to the PES in restraints; referral not initiated by the patient; arrival between 1900 and 0059 hours; bipolar mania or mixed episode; and clinician rating of severe disruptiveness, psychosis or insight impairment. Severe suicidality and a depression diagnosis were associated with less risk of restraint or seclusion. Acute symptomatology and characteristics of the encounter were more likely to be associated with restraint/seclusion than patient demographics or diagnoses. These findings support recent guidelines for the treatment of agitation and can help clinicians identify patients at risk of behavioral decompensation. © 2014.

Use of physical restraints in adult critical care: a bicultural study.

PubMed

Martin, Beth; Mathisen, Lars

2005-03-01

Although controversial, physical restraints are commonly used in adult critical care units in the United States to prevent treatment interference and self-inflicted harm. Use of physical restraints in Norwegian hospitals is very limited. In the United States, an experimental design for research on use of restraints has not seemed feasible. However, international research provides an opportunity to compare and contrast practices. To describe the relationship between patients' characteristics, environment, and use of physical restraints in the United States and Norway. Observations of patients and chart data were collected from 2 intensive care units (n = 50 patients) in Norway and 3 (n = 50 patients) in the United States. Sedation was measured by using the Sedation-Agitation Scale. The Nine Equivalents of Nursing Manpower Use Score was used to indicate patients' acuity level. Restraints were in use in 39 of 100 observations in the United States and not at all in Norway (P = .001). Categories of patients were balanced. In the Norwegian sample, the median Nine Equivalents of Nursing Manpower Use Score was higher (37 vs 27 points, P < .001), patients were more sedated (P < .001), and nurse-to-patient ratios were higher (1.05:1 vs 0.65:1, P < .001). Seven incidents of unplanned device removal were reported in the US sample. Critical care units with similar technology and characteristics of patients vary between nations in restraint practices, levels of sedation, and nurse-to-patient ratios. Restraint-free care was, in this sample, safe in terms of treatment interference.

The Influence of Restraint Systems on Panel Behavior

NASA Technical Reports Server (NTRS)

Jegley, Dawn C.

2011-01-01

When a panel is tested in uniaxial compression in a test machine, the boundary conditions are not quite the same as they would be if it were part of a complete structure. A restraint system may be used to simulate conditions found in a complete vehicle. Quantifying the quality of the restraint with only point-measurement devices can leave an inadequate characterization of the out-of-plane behavior. However, today s full-field displacement monitoring techniques allow for much more accurate views of the global panel deformation and strain, and therefore allow for a better understanding of panel behavior. In the current study, the behavior of a hat-stiffened and two rod-stiffened carbon-epoxy panels is considered. Panels were approximately 2 meters tall and 0.76 to 1.06 m wide. Unloaded edges were supported by knife edges and stiffeners were attached to a support structure at selected locations to restrain out-of-plane motion. A comparison is made between test results based on full-field measurements and analyses based on assumptions of boundary conditions of a completely rigid edge restraint and the absence of any edge restraint. Results indicate that motion at the restrained edges must be considered to obtain accurate test-analysis correlation.

Predatory Functional Morphology in Raptors: Interdigital Variation in Talon Size Is Related to Prey Restraint and Immobilisation Technique

Fowler, Denver W.; Freedman, Elizabeth A.; Scannella, John B.

Despite the ubiquity of raptors in terrestrial ecosystems, many aspects of their predatory behaviour remain poorly understood. Surprisingly little is known about the morphology of raptor talons and how they are employed during feeding behaviour. Talon size variation among digits can be used to distinguish families of raptors and is related to different techniques of prey restraint and immobilisation. The hypertrophied talons on digits (D) I and II in Accipitridae have evolved primarily to restrain large struggling prey while they are immobilised by dismemberment. Falconidae have only modest talons on each digit and only slightly enlarged D-I and II. For immobilisation, Falconini rely more strongly on strike impact and breaking the necks of their prey, having evolved a ‘tooth’ on the beak to aid in doing so. Pandionidae have enlarged, highly recurved talons on each digit, an adaptation for piscivory, convergently seen to a lesser extent in fishing eagles. Strigiformes bear enlarged talons with comparatively low curvature on each digit, part of a suite of adaptations to increase constriction efficiency by maximising grip strength, indicative of specialisation on small prey. Restraint and immobilisation strategy change as prey increase in size. Small prey are restrained by containment within the foot and immobilised by constriction and beak attacks. Large prey are restrained by pinning under the bodyweight of the raptor, maintaining grip with the talons, and immobilised by dismemberment (Accipitridae), or severing the spinal cord (Falconini). Within all raptors, physical attributes of the feet trade off against each other to attain great strength, but it is the variable means by which this is achieved that distinguishes them ecologically. Our findings show that interdigital talon morphology varies consistently among raptor families, and that this is directly correlative with variation in their typical prey capture and restraint strategy.

Physical restraint in psychiatric units is a common practice but extremely controversial and poorly evaluated by methodologically appropriate investigations. The cultural issues and professionals' perceptions and attitudes are substantial contributors to the frequency of restraint that tend to be elevated. Aim In this qualitative study, we aimed to understand the experiences and perceptions of nursing staff regarding physical restraint in psychiatric units. Through theoretical sampling, 29 nurses from two Brazilian psychiatric units participated in the study. Data were collected from 2014 to 2016 from individual interviews and analyzed through thematic analysis, employing theoretical presuppositions of symbolic interactionism. Physical restraint was considered unpleasant, challenging, risky, and associated with dilemmas and conflicts. The nursing staff was often exposed to the risks and injuries related to restraint. Professionals sought strategies to reduce restraint-related damages, but still considered it necessary due to the lack of effective options to control aggressive behavior. This study provides additional perspectives about physical restraint and reveals the need for safer, humanized and appropriate methods for the care of aggressive patients that consider the real needs and rights of these patients.

Reference governors for controlled belt restraint systems

Today's restraint systems typically include a number of airbags, and a three-point seat belt with load limiter and pretensioner. For the class of real-time controlled restraint systems, the restraint actuator settings are continuously manipulated during the crash. This paper presents a novel control strategy for these systems. The control strategy developed here is based on a combination of model predictive control and reference management, in which a non-linear device - a reference governor (RG) - is added to a primal closed-loop controlled system. This RG determines an optimal setpoint in terms of injury reduction and constraint satisfaction by solving a constrained optimisation problem. Prediction of the vehicle motion, required to predict future constraint violation, is included in the design and is based on past crash data, using linear regression techniques. Simulation results with MADYMO models show that, with ideal sensors and actuators, a significant reduction (45%) of the peak chest acceleration can be achieved, without prior knowledge of the crash. Furthermore, it is shown that the algorithms are sufficiently fast to be implemented online.

Parent driver characteristics associated with sub-optimal restraint of child passengers.

2006-12-01

To identify parent driver demographic and socioeconomic characteristics associated with the use of sub-optimal restraints for child passengers under nine years. Cross-sectional study using in-depth, validated telephone interviews with parent drivers in a probability sample of 3,818 vehicle crashes involving 5,146 children. Sub-optimal restraint was defined as use of forward-facing child safety seats for infants under one or weighing under 20 lbs, and any seat-belt use for children under 9. Sub-optimal restraint was more common among children under one and between four and eight years than among children aged one to three years (18%, 65%, and 5%, respectively). For children under nine, independent risk factors for sub-optimal restraint were: non-Hispanic black parent drivers (with non-Hispanic white parents as reference, adjusted relative risk, adjusted RR = 1.24, 95% CI: 1.09-1.41); less educated parents (with college graduate or above as reference: high school, adjusted RR = 1.27, 95% CI: 1.12-1.44; less than high school graduate, adjusted RR = 1.36, 95% CI: 1.13-1.63); and lower family income (with $50,000 or more as reference: <$20,000, adjusted RR = 1.23, 95% CI: 1.07-1.40). Multivariate analysis revealed the following independent risk factors for sub-optimal restraint among four-to-eight-year-olds: older parent age, limited education, black race, and income below $20,000. Parents with low educational levels or of non-Hispanic black background may require additional anticipatory guidance regarding child passenger safety. The importance of poverty in predicting sub-optimal restraint underscores the importance of child restraint and booster seat disbursement and education programs, potentially through Medicaid.

With long-standing and widespread high rates of errors in child restraint use, there is a need to identify effective methods to address this problem. Information supplied with products at the point of sale may be a potentially efficient delivery point for such a countermeasure. The aim of this study is to establish whether product materials developed using a consumer-driven approach reduce errors in restraint use among purchasers of new child restraint systems. A cluster randomised controlled trial (cRCT) will be conducted. Retail stores (n=22) in the greater Sydney area will be randomised into intervention sites (n=11) and control sites (n=11), stratified by geographical and socioeconomic indicators. Participants (n=836) will enter the study on purchase of a restraint. Outcome measures are errors in installation of the restraint as observed by a trained researcher during a 6-month follow-up home assessment, and adjustment checks made by the parent when the child is placed into the restraint (observed using naturalistic methods). Process evaluation measures will also be collected during the home visit. An intention-to-treat approach will be used for all analyses. Correct use and adjustment checks made by the parent will be compared between control and intervention groups using a logistic regression model. The number of installation errors between groups will be compared using Poisson regression. This cRCT will determine the effectiveness of targeted, consumer-driven information on actual error rates in use of restraints. More broadly, it may provide a best practice model for developing safety product information.

Minimizing Restraint and Seclusion in Schools: A Response to Beaudoin and Moore.

PubMed

Walker, Virginia L; Pinkelman, Sarah E

2018-06-01

Increasing efforts have been made in the field of special education to identify positive, evidence-based practices (EBPs) to meet the needs of students who engage in problem behavior, with a major goal being to eliminate or limit the use of reactive measures such as restraint and seclusion ( Snell & Walker, 2014 ). Various stakeholders, including families and self-advocates, have voiced concerns about the dangers of restraint and seclusion and the lack of protection afforded to students who engage in severe problem behavior. In the previous article in this issue of Intellectual and Developmental Disabilities, Beaudoin and Moore (2018) echo these concerns in their account of a family's experience with restraint as told from the perspective of a father whose son was subjected to restraint, resulting in a number of adverse short- and long-term consequences that affected the entire family. In response to Beaudoin and Moore, we provide readers with a brief review of the current status of restraint and seclusion in school settings and evidence-based strategies that can be used to address severe problem behavior and reduce the need for restraint and seclusion. For readers interested in exploring restraint and seclusion in greater depth, we suggest recent work by Trader and colleagues (2017) . We also have outlined guidelines for behavior support planning that should be considered by various stakeholders as educators work toward establishing safe and supportive school environments that address a wide range of student behavioral needs.

To identify nursing experience on physical restraint management in Critical Care Units. To analyse similarities and differences in nursing experience on physical restraint management according to the clinical context that they are involved in. A multicentre phenomenological study was carried out including 14 Critical Care Units in Madrid, classified according to physical restraint use: Common/systematic use, lacking/personalised use, and mixed use. Five focus groups (23 participants were selected following purposeful sampling) were convened, concluding in data saturation. Data analysis was focused on thematic content analysis following Colaizzi's method. Six main themes: Physical restraint meaning in Critical Care Units, safety (self-retreat vital devices), contribution factors, feelings, alternatives, and pending issues. Although some themes are common to the 3 Critical Care Unit types, discourse differences are found as regards to indication, feelings, systematic use of pain and sedation measurement tools. In order to achieve real physical restraint reduction in Critical Care Units, it is necessary to have a deep understanding of restraints use in the specific clinical context. As self-retreat vital devices emerge as central concept, some interventions proposed in other settings could not be effective, requiring alternatives for critical care patients. Discourse variations laid out in the different Critical Care Unit types could highlight key items that determine the use and different attitudes towards physical restraint.

Dietary restraint, anxiety, and the relative reinforcing value of snack food in non-obese women.

PubMed

Goldfield, Gary S; Legg, Christine

2006-11-01

This study tested the independent and interactive effects of anxiety and dietary restraint on the relative reinforcing value of snack food. Thirty non-obese, female university students were assigned to one of four groups based on median split scores on measures of dietary restraint and state-anxiety: low-restraint/low-anxiety (n=7), low-restraint/high-anxiety (n=7), high-restraint/low-anxiety (n=9), and high-restraint/high-anxiety (n=7). Participants were provided the choice to earn points for palatable snack foods or fruits and vegetables using a computerized concurrent schedules choice task. The behavioural cost to gain access to snack foods increased across trials, whereas the cost to gain access to fruits and vegetables was held constant across trials. The relative reinforcing value of palatable snack food in relation to fruits and vegetables was defined as the total amount of points earned for snack food. Two-way analysis of covariance, with hunger and hedonic snack food ratings as covariates, showed that dietary restraint and anxiety had a significant interactive effect on the relative reinforcing value of snack food, indicating that the effect of anxiety on snack food reinforcement is moderated by dietary restraint. Specifically, the high-anxiety/low-restraint women found snack food significantly less reinforcing than low-anxiety/low-restraint women, but no differences emerged between high- and low-anxiety women with high-restraint. Neither restraint nor anxiety had an independent effect on the relative reinforcing value of snack food. These findings indicate that anxiety may have a suppressive effect on the relative reinforcing value of snack food in low-restrained eaters, but not an enhancing effect on snack food reinforcement in high-restrained eaters. Clinical implications of these findings are discussed.

2005-11-01

We sought to estimate motor vehicle passenger restraint use among Northwest American Indian children 8 years old or younger and to determine factors associated with using proper (i.e., age and weight appropriate) passenger restraint systems. We surveyed vehicles driven by members of 6 tribes in Idaho, Oregon, and Washington. Associations between proper restraint and child, driver, and vehicle characteristics were analyzed using logistic regression for clustered data. We observed 775 children traveling in 574 vehicles; 41% were unrestrained. Proper restraint ranged from 63% among infant seat-eligible children to 11% among booster seat-eligible children and was associated with younger child's age (odds ratio (OR) per year = 0.60; 95% confidence interval (CI) = 0.48, 0.75), seating location (OR front vs rear=0.27; 95% CI=0.16, 0.44), driver seat belt use (OR=2.39; 95% CI=1.51, 3.80), and relationship (OR for nonparent vs parent=0.28; 95% CI=0.14, 0.58). More than half of drivers felt children could use an adult seat belt earlier than recommended guidelines, and 63% did not correctly identify whether their tribe had child safety seat laws. Children in these communities are inadequately restrained. Restraint use was exceedingly low among booster-eligible children and children riding with unrestrained adults. Interventions emphasizing appropriate restraint use and enforcement of passenger safety laws could reduce the risk of injury or death in motor vehicle accidents.

Relationship between static foot posture and foot mobility

PubMed Central

2011-01-01

Background It is not uncommon for a person's foot posture and/or mobility to be assessed during a clinical examination. The exact relationship, however, between static posture and mobility is not known. Objective The purpose of this study was to determine the degree of association between static foot posture and mobility. Method The static foot posture and foot mobility of 203 healthy individuals was assessed and then analyzed to determine if low arched or "pronated" feet are more mobile than high arched or "supinated" feet. Results The study demonstrated that those individuals with a lower standing dorsal arch height and/or a wider standing midfoot width had greater mobility in their foot. In addition, those individuals with higher Foot Posture Index (FPI) values demonstrated greater mobility and those with lower FPI values demonstrated less mobility. Finally, the amount of foot mobility that an individual has can be predicted reasonably well using either a 3 or 4 variable linear regression model. Conclusions Because of the relationship between static foot posture and mobility, it is recommended that both be assessed as part of a comprehensive evaluation of a individual with foot problems.

Wearable electronic devices have experienced increasing development with the advances in the semiconductor industry and have received more attention during the last decades. This paper presents the development and implementation of a novel inertial sensor-based foot-mounted wearable electronic device for a brand new application: game playing. The main objective of the introduced system is to monitor and identify the human foot stepping direction in real time, and coordinate these motions to control the player operation in games. This proposed system extends the utilized field of currently available wearable devices and introduces a convenient and portable medium to perform exercise in a more compelling way in the near future. This paper provides an overview of the previously-developed system platforms, introduces the main idea behind this novel application, and describes the implemented human foot moving direction identification algorithm. Practical experiment results demonstrate that the proposed system is capable of recognizing five foot motions, jump, step left, step right, step forward, and step backward, and has achieved an over 97% accuracy performance for different users. The functionality of the system for real-time application has also been verified through the practical experiments.

Reward Improves Cancellation and Restraint Inhibition Across Childhood and Adolescence

PubMed Central

Sinopoli, Katia J.; Schachar, Russell; Dennis, Maureen

2011-01-01

Inhibitory control allows for the regulation of thought and action, and interacts with motivational variables, such as reward, to modify behavior adaptively as environments change. We examined the effects of reward on two distinct forms of inhibitory control, cancellation and restraint. Typically developing children and adolescents completed two versions of the stop signal task (cancellation and restraint) under three reward conditions (neutral, low reward, and high reward), where rewards were earned for successful inhibitory control. Rewards improved both cancellation and restraint inhibition, with similar effects of reward on each form of inhibitory control. Rewards did not alter the speed of response execution in either task, suggesting that rewards specifically altered inhibition processes without influencing processes related to response execution. Adolescents were faster and less variable than children when executing and inhibiting their responses. There were similar developmental effects of reward on the speed of inhibitory control, but group differences were found in terms of accuracy of inhibition in the restraint task. These results clarify how reward modulates two different forms of regulatory behavior in children and adolescents. PMID:21744952

Do organisational constraints explain the use of restraint? A comparative ethnographic study from three nursing homes in Norway.

To investigate (1) what kind of restraint is used in three nursing homes in Norway and (2) how staff use restraint under what organisational conditions. Restraint use in residents living with dementia in nursing homes is controversial, and at odds with fundamental human rights. Restraint is a matter of hindering residents' free movement and will by applying either interactional, physical, medical, surveillance or environmental restraint. Previous research has identified use of restraint related to individual resident characteristics such as agitation, aggressiveness and wandering. This model is embedded in an overall mixed-method education intervention design study called Modelling and evaluating evidence-based continuing education program in dementia care (MEDCED), applying ethnography postintervention to examine the use of restraint in 24 nursing homes in Norway. Based on restraint diversity measured in the trial, ethnographic investigation was carried out in three different nursing homes in Norway over a 10-month period to examine restraint use in relation to organisational constraints. Several forms of restraint were observed; among them, interactional restraint was used most frequently. We identified that use of restraint relates to the characteristics of individual residents, such as agitation, aggressiveness and wandering. However, restraint use should also be explained in relation to organisational conditions such as resident mix, staff culture and available human resources. A fluctuating and dynamic interplay between different individual and contextual factors determines whether restraint is used - or not in particular situations with residents living with dementia. Educational initiatives targeting staff to reduce restraint must be sensitive towards fluctuating organisational constraints. © 2016 John Wiley & Sons Ltd.

In this photograph, the Orbital Workshop shower compartment was unfolded by technicians for inspection. The shower compartment was a cylindrical cloth enclosure that was folded flat when not in use. The bottom ring of the shower was fastened to the floor and contained foot restraints. The upper ring contained the shower head and hose. To use the shower, the astronaut filled a pressurized portable bottle with heated water and attached the bottle to the ceiling. A flexible hose cornected the water bottle to a handheld shower head. The astronaut pulled the cylindrical shower wall up into position and bathed, using liquid soap. Both soap and water were carefully rationed, having been premeasured for economical use.

Observed child restraint use in automobiles

PubMed Central

Williams, A.

1998-01-01

Visual observations were made on restraint use in occupants of 5050 automobiles containing at least one passenger less than 10 years of age, and short interviews were conducted with the drivers. Ninety three per cent of passengers less than 10 years old were not restrained. Eighty nine per cent of passengers 10 or older and 78% of the drivers were not restrained. Sixteen per cent of child motor vehicle restraint devices observed were not used, and 73% of those in use were not used correctly. Use of such devices declined sharply after age one. Although child passengers were more likely to be restrained if the driver was restrained, more than 75% of the children were not restrained when the driver was, even if the driver was the child's parent.

Mental health inpatients' and staff members' suggestions for reducing physical restraint: A qualitative study.

PubMed

Wilson, C; Rouse, L; Rae, S; Kar Ray, M

2018-04-01

WHAT IS KNOWN ON THE SUBJECT?: Restraint has negative psychological, physical and relational consequences for mental health patients and staff. Restraint reduction interventions have been developed (e.g., "Safewards"). Limited qualitative research has explored suggestions on how to reduce physical restraint (and feasibility issues with implementing interventions) from those directly involved. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: This paper explores mental health patients' and staff members' suggestions for reducing physical restraint, whilst addressing barriers to implementing these. Findings centred on four themes: improving communication and relationships; staffing factors; environment and space; and activities and distraction. Not all suggestions are addressed by currently available interventions. Barriers to implementation were identified, centring on a lack of time and/or resources; with the provision of more time for staff to spend with patients and implement interventions seen as essential to reducing physical restraint. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Improving communication and relationships between staff/patients, making staffing-related changes, improving ward environments and providing patient activities are central to restraint reduction in mental healthcare. Fundamental issues related to understaffing, high staff turnover, and lack of time and resources need addressing in order for suggestions to be successfully implemented. Introduction Physical restraint has negative consequences for all involved, and international calls for its reduction have emerged. Some restraint reduction interventions have been developed, but limited qualitative research explores suggestions on how to reduce physical restraint (and feasibility issues with implementation) from those directly involved. Aims To explore mental health patients' and staff members' suggestions for reducing physical restraint. Methods Interviews were conducted with 13 inpatients

Dynamics of column stability with partial end restraints

NASA Technical Reports Server (NTRS)

Gregory, Peyton B.

1990-01-01

The dynamic behavior of columns with partial end restraints and loads consisting of a dead load and a pulsating load are investigated. The differential equation is solved using a lumped impulse recurrence formula relative to time coupled with a finite difference discretization along the member length. A computer program is written from which the first critical frequencies are found as a function of end stiffness. The case of a pinned ended column compares very well with the exact solution. Also, the natural frequency and buckling load formulas are derived for equal and unequal end restraints.

New devices for measuring forces on the kayak foot bar and on the seat during flat-water kayak paddling: a technical report.

PubMed

Nilsson, Johnny E; Rosdahl, Hans G

2014-03-01

The purpose was to develop and validate portable force-measurement devices for recording push and pull forces applied by each foot to the foot bar of a kayak and the horizontal force at the seat. A foot plate on a single-point force transducer mounted on the kayak foot bar underneath each foot allowed the push and pull forces to be recorded. Two metal frames interconnected with 4 linear ball bearings, and a force transducer allowed recording of horizontal seat force. The foot-bar-force device was calibrated by loading each foot plate with weights in the push-pull direction perpendicular to the foot plate surface, while the seat-force device was calibrated to horizontal forces with and without weights on the seat. A strong linearity (r2 = .99-1.0) was found between transducer output signal and load force in the push and pull directions for both foot-bar transducers perpendicular to the foot plate and the seat-force-measuring device. Reliability of both devices was tested by means of a test-retest design. The coefficient of variation (CV) for foot-bar push and pull forces ranged from 0.1% to 1.1%, and the CV for the seat forces varied from 0.6% to 2.2%. The current study opens up a field for new investigations of the forces generated in the kayak and ways to optimize kayak-paddling performance.

2016-11-01

To develop an internationally accepted research definition of physical restraint. Comprehensive literature search followed by a web-based, three-round, modified Delphi technique comprising reviews and feedback. Clinical care settings. An international group of 48 experts consisting of researchers and clinicians from 14 countries who have made sustained contribution to research and clinical application in the field of physical restraint in clinical care. Data were collected using an online survey program and one in-person meeting. Results of the online survey and the in-person meeting were used for distribution in subsequent rounds until consensus on a definition was reached. Consensus was defined as 90% of the participating experts agreeing with the proposed definition of physical restraint. Thirty-four different definitions were identified during the literature search and served as a starting point for the modified Delphi technique. After three rounds, 45 (95.7%) of 47 remaining experts agreed with the newly proposed definition: "Physical restraint is defined as any action or procedure that prevents a person's free body movement to a position of choice and/or normal access to his/her body by the use of any method, attached or adjacent to a person's body that he/she cannot control or remove easily." A multidisciplinary, internationally representative panel of experts reached consensus on a research definition for physical restraints in older persons. This is a necessary step toward improved comparisons of the prevalence of physical restraint use across studies and countries. This definition can further guide research interventions aimed at reducing use of physical restraints. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Physical Restraint Use With Elderly Patients: Perceptions of Nurses and Nursing Assistants in Spanish Acute Care Hospitals.

PubMed

Fariña-López, Emilio; Estévez-Guerra, Gabriel J; Polo-Luque, M Luz; Hanzeliková Pogrányivá, Alica; Penelo, Eva

Physical restraint is often used during the hospitalization of elderly people. However, this procedure is associated with adverse outcomes; therefore, it is necessary to be aware of the circumstances that promote restraint use, such as the perceptions of professionals who use it. The purpose of the research was to determine the situations in which nursing staff considered the use of physical restraint as most important and to evaluate the possible associations with the sociodemographic and professional variables. A descriptive cross-sectional multicenter study was carried out in 52 units of eight Spanish acute hospitals. A survey of registered nurses and nursing assistants was used to collect data related to sociodemographic characteristics, experience, training in restraint use, and the Perception of Restraint Use Questionnaire (PRUQ)-which assesses the perceived importance of reasons frequently given for the use of physical restraint. The sample comprised 508 registered nurses and 347 nursing assistants. Almost all (98%) had used physical restraint, and 82% thought their training in the use of physical restraint was insufficient. Nursing assistants scored higher than registered nurses (p < .005, d = .68) on PRUQ total score and individual item scores, suggesting they thought the factors were more important in restraint use. Both registered nurses and nursing assistants considered restraint as most important in the prevention of falls and in the removal of medical devices such as intravenous lines and urinary catheters. Associations between PRUQ total score and other variables (unit type, sociodemographic factors, hospital) were nonsignificant. The professionals considered restraint as very important in preventing safety problems. In order to improve the quality of care, it is essential to identify the factors that can have an effect on the application of physical restraint. Educational programs are of fundamental importance, but to be more effective in reducing

To study the internal structure and measurement invariance of the Physical Restraint Use Questionnaire and to compare perceptions, experience and training, regarding use of physical restraint on the older people between nursing staff working in hospitals and nursing homes. Physical restraint of patients is still common in many countries, and thus, it is important to study the attitudes of nursing staff. One of the most common tools used to assess perceptions regarding its use is the Physical Restraint Use Questionnaire. However, gaps exist in its internal structure and measurement invariance across different groups of respondents. Cross-sectional multicentre survey. Data were collected from nurses working in eight Spanish hospitals and 19 nursing homes. All registered nurses and nurse assistants (N = 3,838) were contacted, of whom 1,635 agreed to participate. Confirmatory factor analysis was performed to determine internal structure and measurement invariance of Physical Restraint Use Questionnaire, after which scale scores and other measures of experience and training were compared between hospital-based (n = 855) and nursing homes-based (n = 780) nurses. The Physical Restraint Use Questionnaire showed three invariant factors across type of facility, and also professional category and sex. Nursing staff working in both types of facility scored similarly; prevention of therapy disruption and prevention of falls were rated more important. Nurses working in nursing homes reported using restraint "many times" more frequently (52.9% vs. 38.6%), less severe lack of training (18.2% vs. 58.7%) being perceived as more adequate (33.4% vs. 17.7%), than hospital-based nurses. These findings support Physical Restraint Use Questionnaire as a valid and reliable tool for assessing the importance given to the use of physical restraint in the older people by nursing professionals, regardless of the setting being studied. The information would help design more specifically the

Tethered-restraint system for blood collection from ferrets

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jackson, R.K.; Kieffer, V.A.; Sauber, J.S.

The laboratory ferret, Mustela putorius furo, recently has come into prominence as a laboratory animal for use in biomedical research. This laboratory has adopted the use of this species because the ferret's emetic response to radiation occurs at a lower dose and has a more rapid onset than that of dogs. One approach for determining the physiological basis of this response is to measure serum levels of various circulating substances before and after irradiation. However, blood collection from the ferret can be difficult because the lack of easily accessible veins and seasonal accumulation of subcutaneous body fat. This report describesmore » a method of tethered-restraint for the ferret in which an in-dwelling venous jugular catheter is implanted for withdrawing blood samples. No interference with the animal's normal activities occurs during the sampling procedure. Each animal is conditioned to the tethered-restraint prior to surgical placement of the catheter. The technique provides a minimally stressful method of restraint. A similar tethering system has been used successfully on several other animal species, such as non-human primates and rats.« less

2011-12-01

The Individual Differences Model posits that individual differences in physiological and psychological factors explain eating behaviors in response to stress. The purpose was to determine the effects of individual differences in adiposity, dietary restraint and stress reactivity on children's energy intake and food choices. A total of 40 boys and girls, age 8-12 years, with wide ranges of dietary restraint, adiposity, and stress reactivity were measured for total energy intake and choice of energy dense 'comfort' and lower density 'healthy' foods following reading and speech stressor manipulations. When exploring the interaction of dietary restraint and stress reactivity, lower restraint/lower reactivity and lower restraint/higher reactivity were associated with reductions in energy intake (37-62 kcal) and comfort food (33-89 kcal). Higher restraint/lower reactivity was associated with consuming 86 fewer total kcal and 45 fewer kcal of comfort food. Only higher restraint/higher reactivity predicted increased energy intake (104 kcal) and comfort food (131 kcal). The interaction of dietary restraint and percentage body fat revealed that lower restraint/lower adiposity was associated with consuming 123 fewer kcal after being stressed with the entire reduction due to a decrease in comfort food. Lower restraint/higher adiposity was associated with consuming 116 kcal more after being stressed with 70% (81 kcal) of the increase in the form of comfort foods. Higher restraint/lower adiposity and higher restraint/higher adiposity were associated with smaller changes in total energy intake of 22 kcal and 1 kcal; respectively. Both restraint and adiposity moderated the effect of stress on energy intake and food choice. Children with greater adiposity may be at risk for stress-induced eating to contribute to their obesity.

2013-01-01

This study was carried out to determine knowledge, attitudes, and practices of intern nurses who completed the nursing internship program on the use of physical restraints. This research was conducted using descriptive and cross-sectional research design. The study sample comprises 91 fourth-grade students who took an integrated curriculum and completed the nursing internship program. The data were collected with the Demographic Characteristics Questionnaire and the Levels of Knowledge, Attitudes and Practices of Staff Regarding Physical Restraints Questionnaire. For the assessment of the data, percentages, the arithmetic mean, and t test were used. The findings indicated that, of the intern nurses, 95.6% observed the use of physical restraints during their education, and 69.2% applied physical restraints. The mean knowledge, attitude, and practice scores of the nurses for physical restraint were 9.38 ± 1.19 (0-11 points), 34.70 ± 5.62 (12-48 points), and 37.95 ± 2.32 (14-42 points), respectively. Intern nurses' knowledge about how to use physical restraints was at a very good level; they displayed positive attitudes, and they used their knowledge and attitudes in their practices to a great extent. Although there are studies on the knowledge, attitudes, and practices of nurses working in the fields of elderly care, rehabilitation, and psychiatry in acute care units, there are no studies investigating intern nurses and other nursing students. However, intern nurses about to begin their careers should make accurate decisions regarding the use of physical restrains if they are to ensure patient safety and to fulfill this application effectively in their professional lives.

For Croatian student population the scatter data of the individual foot variables were interpolated by multivariate statistics. Foot morphometric descriptors are influenced by many factors, such as life style, climate, and things of great importance in human society. Dominant descriptors related to fit and comfort are determined by the use 3D foot shape and advanced foot biomechanics. Some practical recommendations and conclusions for medical, sportswear and footwear practice are highlighted.

This study is an attempt to show how a "standard" foot can be parameterized using foot length, foot width, foot height, and a measure of foot curvature so that foot shape can be predicted using these simple anthropometric measures. The prediction model was generated using 40 Hong Kong Chinese men, and the model was validated using a different group of 25 Hong Kong Chinese men. The results show that each individual foot shape may be predicted to a mean accuracy of 2.1 mm for the left foot and 2.4 mm for the right foot. Application of this research includes the potential design and development of custom footwear without the necessity of expensive 3-D scanning of feet.

Use of monkeys in research has often required that they be restrained in a chair. However, chair restraint can elicit an initial neuroendocrine stress response. Also, inactivity associated with restraint can induce muscular atrophy. We proposed that prior habituation of monkeys to chair restraint would attenuate these neuroendocrine responses without causing substantial muscle wasting. Four rhesus monkeys (Macaca mulatta) were trained and habituated to a restraint chair specifically designed for spaceflight. During the study, monkeys were placed in metabolic cages for 7 days (prerestraint, Phase I), placed in a chair restraint for 18 days (Phase II), and then returned to their metabolic cages for 5 days (postrestraint, Phase III). Urine was collected between 0700-1100 daily, and measurements of cortisol, creatinine, and electrolyte concentrations were adjusted for hourly excretion rates. Body weights of the monkeys did not change between start of the prerestraint and postrestraint phases (10.3 +/- 0.8 vs. 10.3 +/- 0.9 kg, respectively). During the 3 phases, mean excretion rate of cortisol did not change (24.1 +/- 10.3, 26.7 +/- 7.7, and 19.3 +/- 5.8 microg/h, respectively). Mean excretion rate of creatinine (37.3 +/- 7.5, 37.5 +/- 12.2, and 36.9 +/- 17.1 mg/h, respectively), Na+ (3.3 +/- 1.2, 3.2 +/- 1.2, 2.2 +/- 1.8 mmol/h, respectively), and K+ (5.3 +/- 1.8, 5.4 +/- 1.6, and 4.3 +/- 2.8 mmol/h, respectively) were also not altered. Lack of an increase in excreted urinary cortisol suggested that prior habituation to chair restraint attenuated neuroendocrine responses reported previously. Also, the chair restraint method used appeared to allow adequate activity, because the monkeys did not have indices of muscle wasting.

Effects of dietary restraint and body mass index on the relative reinforcing value of snack food.

PubMed

Goldfield, Gary S; Lumb, Andrew

2009-01-01

The present study examined the independent and interactive association between dietary restraint, body mass index (BMI) and the relative reinforcing value of food. Four hundred and three introductory psychology students completed questionnaires assessing age, gender, BMI, hunger, smoking status, nicotine dependence, dietary restraint, hedonic ratings for snack food and fruits and vegetables and the relative reinforcing value of snack food and fruits and vegetables. In the overall sample, results indicated a dietary restraint x BMI interaction after controlling for age, hunger, nicotine dependence, and hedonics. However, when regression models were separated by gender, the BMI x restraint interaction emerged only for females and not for males. Findings suggest that BMI moderates the relationship between dietary restraint and snack food reinforcement in females only, such that restraint and snack food reinforcement are inversely correlated in females with lower BMI, but restraint is positively correlated with snack food reinforcement in females with higher BMI. Theoretical and clinical implications of these findings are discussed.

This study was conducted to verify the effects of an education program of restraints use on nurses' knowledge, attitude and nursing performance related to restraints use. A quasi experimental study with a pre and post non-equivalent design was used. The subjects were nurses who met the selection criteria and worked in intensive care units of two university hospitals located at K-city, Gyeongbuk. Twenty nurses in A hospital were designated as the experimental group and 20 nurses in B hospital as the control group. The first hypothesis which assumed that the experimental group would have higher scores of knowledge than the control group was supported(F=62.66, p=0.000). The second hypothesis which assumed that the experimental group would have lower scores of attitude toward using restraints than the control group was supported(F=23.77, p=0.000). The third hypothesis which assumed that the experimental group would have higher scores of nursing performance than the control group was supported(F=3.28, p=0.032). An education program for nurses' on the use of restraints needs to be introduced to decrease inappropriate use of restraints.

The STAFF-project investigates in what way 'smart technology' can offer an alternative for physical restraints in nursing homes. A survey is realized aimed at gaining more insight into the vision on and the use of physical restraints and 'smart technology'. Two partly overlapping structured questionnaires were developed and sent to nursing home staff in Flanders (Belgium). One hundred fifty six administrators (managers or assistant-managers) and 238 caregiving staff (nurses, nursing aids, paramedical staff and other) completed the online questionnaire. In general there is a low acceptability of physical restraint use, however, a more nuanced picture of acceptability is present depending on the specific motivation for using physical restraints and on the specific means of physical restraints. About half of the administrators say they use smart technology in the nursing home. The two main reasons for not applying (yet) smart technology are 'too high price for smart technology' and 'inadequate infrastructure of the nursing home'. All respondents underscore the importance of multiple strategies to diminish the use of physical restraints in nursing homes. Physical restraint use is a complex theme and needs a nuanced analysis and management. This study shows that there is still room for improvement in diminishing the use of physical restraints and that nursing homes in Flanders are open to use smart technology.

Functional analyses produced inconclusive results regarding variables that maintained problem behavior for 2 students with developmental disabilities. Procedures were modified to include a contingent physical restraint condition based on in-class observations. Results indicated that tinder conditions in which physical restraint (i.e., basket-hold timeout) was applied contingent on problem behavior, rates of these behaviors increased across sessions for both subjects. Implications for the use of physical restraint in the classroom are discussed.

Research study on neck injury lessening with active head restraint using human body FE model.

The objective of this study is to examine the effectiveness of the active head restraint system in reducing neck injury risk of car occupants in low-speed rear impacts. A human body FE model "THUMS" was used to simulate head and neck kinematics of the occupant and to evaluate loading to the neck. Joint capsule strain was calculated to predict neck injury risk as well as NIC. The validity of the model was confirmed comparing its mechanical responses to those in human subjects in the literatures. Seat FE models were also prepared representing one with a fixed head restraint and the other one with an active head restraint system. The active head restraint system was designed to move the head restraint forward and upward when the lower unit was lower unit was loaded by the pelvis. Rear impact simulations were performed assuming a triangular acceleration pulse at a delta-V of 25 km/h. The model reproduced similar head and neck motions to those measured in the human volunteer test, except for active muscular responses. The calculated joint capsule strain also showed a good match with those of PMHS tests in the literature. A rear-impact simulation was conducted using the model with the fixed head restraint. The result revealed that NIC was strongly correlated with the relative acceleration between the head and the torso and that its maximum peak appeared when the head contacted the head restraint. It was also found that joint capsule strain grew in later timing synchronizing with the relative displacement. Another simulation with the active head restraint system showed that both NIC and joint capsule strain were lowered owing to the forward and upward motion of the head restraint. A close investigation of the vertebral motion indicated that the active head restraint reduced the magnitude of shear deformation in the facet joint, which contributed to the strain growth in the fixed head restraint case. Rear-impact simulations were conducted using a human body FE model, THUMS

To evaluate the effectiveness of a multifactorial intervention to reduce the use of physical restraints in residents of nursing homes. Cluster-randomized controlled trial. Forty-five nursing homes in Germany. Three hundred thirty-three residents who were being restrained at the start of the intervention. Persons responsible for the intervention in the nursing homes attended a 6-hour training course that included education about the reasons restraints are used, the adverse effects, and alternatives to their use. Technical aids, such as hip protectors and sensor mats, were provided. The training was designed to give the change agents tools for problem-solving to prevent behavioral symptoms and injuries from falls without using physical restraints. The main outcome was the complete cessation of physical restraint use on 3 consecutive days 3 months after the start of the intervention. Secondary outcomes were partial reductions in restraint use, percentage of fallers, number of psychoactive drugs, and occurrence of behavioral symptoms. The probability of being unrestrained in the intervention group (IG) was more than twice that in the control group (CG) at the end of the study (odds ratio=2.16, 95% confidence interval=1.05-4.46). A partial reduction of restraint use was also about twice as often achieved in the IG as in the CG. No negative effect was observed regarding medication or behavioral symptoms. The percentage of fallers was higher in the IG. The intervention reduced restraint use without a significant increase in falling, behavioral symptoms, or medication. © 2011, Copyright the Authors.

Design and optimization for the occupant restraint system of vehicle based on a single freedom model

Zhang, Junyuan; Ma, Yue; Chen, Chao; Zhang, Yan

2013-05-01

Throughout the vehicle crash event, the interactions between vehicle, occupant, restraint system (VOR) are complicated and highly non-linear. CAE and physical tests are the most widely used in vehicle passive safety development, but they can only be done with the detailed 3D model or physical samples. Often some design errors and imperfections are difficult to correct at that time, and a large amount of time will be needed. A restraint system concept design approach which based on single-degree-of-freedom occupant-vehicle model (SDOF) is proposed in this paper. The interactions between the restraint system parameters and the occupant responses in a crash are studied from the view of mechanics and energy. The discrete input and the iterative algorithm method are applied to the SDOF model to get the occupant responses quickly for arbitrary excitations (impact pulse) by MATLAB. By studying the relationships between the ridedown efficiency, the restraint stiffness, and the occupant response, the design principle of the restraint stiffness aiming to reduce occupant injury level during conceptual design is represented. Higher ridedown efficiency means more occupant energy absorbed by the vehicle, but the research result shows that higher ridedown efficiency does not mean lower occupant injury level. A proper restraint system design principle depends on two aspects. On one hand, the restraint system should lead to as high ridedown efficiency as possible, and at the same time, the restraint system should maximize use of the survival space to reduce the occupant deceleration level. As an example, an optimization of a passenger vehicle restraint system is designed by the concept design method above, and the final results are validated by MADYMO, which is the most widely used software in restraint system design, and the sled test. Consequently, a guideline and method for the occupant restraint system concept design is established in this paper.

Foot Pain and Pronated Foot Type are Associated with Self-Reported Mobility Limitations in Older Adults: the Framingham Foot Study

Background The foot plays an important role in supporting the body when undertaking weight bearing activities. Aging is associated with an increased prevalence of foot pain and a lowering of the arch of the foot, both of which may impair mobility. Objective To examine the associations of foot pain, foot posture and dynamic foot function with self-reported mobility limitations in community-dwelling older adults. Methods Foot examinations were conducted on 1,860 members of the Framingham Study in 2002–2005. Foot posture was categorized as normal, planus or cavus using static pressure measurements, and foot function was categorized as normal, pronated or supinated using dynamic pressure measurements. Participants were asked whether they had foot pain and any difficulty performing a list of nine weight bearing tasks. Multivariate logistic regression and linear regression models were used to examine the associations of foot pain, posture, function and ability to perform these activities. Results After adjusting for age, sex, height and weight, foot pain was significantly associated with difficulty performing all nine weight bearing activities. Compared to those with normal foot posture and function, participants with planus foot posture were more likely to report difficulty remaining balanced (odds ratio [OR] = 1.40, 95% confidence interval [CI] 1.06 to 1.85; p=0.018) and individuals with pronated foot function were more likely to report difficulty walking across a small room (OR = 2.07, 95% CI 1.02 to 4.22; p=0.045). Foot pain and planus foot posture were associated with an overall mobility limitation score combining performances on each measure. Conclusion Foot pain, planus foot posture and pronated foot function are associated with self-reported difficulty undertaking common weight bearing tasks. Interventions to reduce foot pain and improve foot posture and function may therefore have a role in improving mobility in older adults. PMID:26645379

Ventricular restraint is a nontransplantation surgical treatment for heart failure. The effect of varying restraint level on left ventricular (LV) mechanics and remodeling is not known. We hypothesized that restraint level may affect therapy efficacy. We studied the immediate effect of varying restraint levels in an ovine heart failure model. We then studied the long-term effect of restraint applied over a 2-month period. Restraint level was quantified by use of fluid-filled epicardial balloons placed around the ventricles and measurement of balloon luminal pressure at end diastole. At 4 different restraint levels (0, 3, 5, and 8 mm Hg), transmural myocardial pressure (P(tm)) and indices of myocardial oxygen consumption (MVO2) were determined in control (n=5) and ovine heart failure (n=5). Ventricular restraint therapy decreased P(tm) and MVO2, and improved mechanical efficiency. An optimal physiological restraint level of 3 mm Hg was identified to maximize improvement without an adverse affect on systemic hemodynamics. At this optimal level, end-diastolic P(tm) and MVO2 indices decreased by 27% and 20%, respectively. The serial longitudinal effects of optimized ventricular restraint were then evaluated in ovine heart failure with (n=3) and without (n=3) restraint over 2 months. Optimized ventricular restraint prevented and reversed pathological LV dilatation (130+/-22 mL to 91+/-18 mL) and improved LV ejection fraction (27+/-3% to 43+/-5%). Measured restraint level decreased over time as the LV became smaller, and reverse remodeling slowed. Ventricular restraint level affects the degree of decrease in P(tm), the degree of decrease in MVO2, and the rate of LV reverse remodeling. Periodic physiological adjustments of restraint level may be required for optimal restraint therapy efficacy.

We used an organizational behavior management (OBM) approach to increase behavior intervention plans and decrease the use of mechanical restraint. First, recipients were tracked as a member of the priority group if they engaged in frequent self-injurious behavior or physical aggression toward others and/or if they had been placed in mechanical restraint as a result of the problem behaviors. Second, a behavior data monitoring and feedback system was put in place. Third, organizational contingencies for the use of mechanical restraint or the occurrence of frequent self-injurious behavior or physical aggression toward others were initiated. Over the course of 17 months, behavior intervention plans were more than doubled to 124 and mechanical restraints decreased by almost 80%. This study represents the first to use an organizational behavior management (OBM) to reduce restraint with people who have intellectual disabilities. Copyright © 2011 Elsevier Ltd.

Diffraction-Based Density Restraints for Membrane and Membrane-Peptide Molecular Dynamics Simulations

2006-01-01

We have recently shown that current molecular dynamics (MD) atomic force fields are not yet able to produce lipid bilayer structures that agree with experimentally-determined structures within experimental errors. Because of the many advantages offered by experimentally validated simulations, we have developed a novel restraint method for membrane MD simulations that uses experimental diffraction data. The restraints, introduced into the MD force field, act upon specified groups of atoms to restrain their mean positions and widths to values determined experimentally. The method was first tested using a simple liquid argon system, and then applied to a neat dioleoylphosphatidylcholine (DOPC) bilayer at 66% relative humidity and to the same bilayer containing the peptide melittin. Application of experiment-based restraints to the transbilayer double-bond and water distributions of neat DOPC bilayers led to distributions that agreed with the experimental values. Based upon the experimental structure, the restraints improved the simulated structure in some regions while introducing larger differences in others, as might be expected from imperfect force fields. For the DOPC-melittin system, the experimental transbilayer distribution of melittin was used as a restraint. The addition of the peptide caused perturbations of the simulated bilayer structure, but which were larger than observed experimentally. The melittin distribution of the simulation could be fit accurately to a Gaussian with parameters close to the observed ones, indicating that the restraints can be used to produce an ensemble of membrane-bound peptide conformations that are consistent with experiments. Such ensembles pave the way for understanding peptide-bilayer interactions at the atomic level. PMID:16950837

Common foot problems in diabetic foot clinic.

To study common foot problems presented in diabetic foot clinic. A retrospectively review of out patient department records and diabetic foot evaluation forms of patients who visited the diabetic foot clinic at King Chulalongkorn Memorial Hospital between 2004 and 2006. Of all diabetic patients, 70 men and 80 women with the average age of 63.8 years were included in this study. About 32% of all reported cases had lower extremity amputation in which the toe was the most common level. Foot problems were evaluated and categorized in four aspects, dermatological, neurological, musculoskeletal, and vascular, which were 67.30%, 79.3%, 74.0%, and 39.3% respectively. More than half of the patients had skin dryness, nail problem and callus formation. Fifty six percent had the abnormal plantar pressure area, which was presented as callus. The great toe was the most common site of callus formation, which was correlated with gait cycle. The current ulcer was 18.8%, which was presented mostly at heel and great toe. Three-fourth of the patients (75.3%) had lost protective sensation, measured by the 5.07 monofilament testing. The most common problem found in musculoskeletal system was limited motion of the joint (44.0%). Claw toe or hammer toe were reported as 32.0% whereas the other deformities were bunnion (12.0%), charcot joint (6.0%) and flat feet (5.3%). The authors classified patients based on category risk to further lower extremity amputation into four groups. Forty-seven percent had highest risk for having further amputation because they had lost protective sensation from monofilament testing, previous current ulcer, or history of amputation. Only half of the patients had previous foot care education. Multidisciplinary diabetic foot care including patient education (proper foot care and footwear), early detection, effective management of foot problems, and scheduled follow-up must be emphasized to prevent diabetes-related lower extremities amputation.

Use of top tethers with forward-facing child restraints: observations and driver interviews.

Despite the safety benefits, many parents do not use top tethers with forward-facing child restraints. Detailed information was collected about why parents are not using tethers. The sample included 479 drivers who had forward-facing child restraints installed in passenger vehicles equipped with tether anchors. The survey was conducted primarily at shopping centers, recreation facilities, child care facilities, car seat check events, and health care facilities in mostly suburban areas surrounding Philadelphia, Washington, DC, Fredericksburg (VA), and Seattle. Drivers were surveyed about their knowledge and use of tethers and experience with child restraints. Tether use was observed to verify whether tethers were being used correctly. Fifty-six percent of forward-facing child restraints were installed with the tether; 39% were installed with the tether used correctly. The tether was used with 71% of LATCH lower anchor installations and 33% of seat belt installations. Drivers who installed child restraints without tethers most often said they did not know about the tether or how to use it. Although the tether use rate was slightly higher in the current research than in previous studies, many parents and caregivers still use forward-facing child restraints without attaching the tether. Because the main problem is lack of awareness of the tether or how to use it, public education should focus specifically on the safety benefits of tethers and how to use them. Information about why caregivers fail to use top tethers is potentially useful to child restraint manufacturers, child passenger safety technicians, and others who work with parents to improve motor vehicle safety.

We hypothesized that acute stress would induce endothelial dysfunction. Male Wistar rats were restrained for 2 h within wire mesh. Functional and biochemical analyses were conducted 24 h after the 2-h period of restraint. Stressed rats showed decreased exploration on the open arms of an elevated-plus maze (EPM) and increased plasma corticosterone concentration. Acute restraint stress did not alter systolic blood pressure, whereas it increased the in vitro contractile response to phenylephrine and serotonin in endothelium-intact rat aortas. NG-nitro-l-arginine methyl ester (l-NAME; nitric oxide synthase, NOS, inhibitor) did not alter the contraction induced by phenylephrine in aortic rings from stressed rats. Tiron, indomethacin and SQ29548 reversed the increase in the contractile response to phenylephrine induced by restraint stress. Increased systemic and vascular oxidative stress was evident in stressed rats. Restraint stress decreased plasma and vascular nitrate/nitrite (NOx) concentration and increased aortic expression of inducible (i) NOS, but not endothelial (e) NOS. Reduced expression of cyclooxygenase (COX)-1, but not COX-2, was observed in aortas from stressed rats. Restraint stress increased thromboxane (TX)B(2) (stable TXA(2) metabolite) concentration but did not affect prostaglandin (PG)F2α concentration in the aorta. Restraint reduced superoxide dismutase (SOD) activity, whereas concentrations of hydrogen peroxide (H(2)O(2)) and reduced glutathione (GSH) were not affected. The major new finding of our study is that restraint stress increases vascular contraction by an endothelium-dependent mechanism that involves increased oxidative stress and the generation of COX-derived vasoconstrictor prostanoids. Such stress-induced endothelial dysfunction could predispose to the development of cardiovascular diseases.

Head restraint backset during routine automobile driving: drivers usually exceed the recommended guidelines.

Although several previous studies have evaluated horizontal head restraint backset distances, few studies have evaluated them during driving. The purpose of this study was to measure this backset during routine automobile driving and to specifically evaluate the backset during individual driving tasks such as turning, stopping, starting, and lane changes. Fourteen subjects drove around a specified route through the city of Guelph, Ontario, Canada, that included residential, thruway, and highway driving; additional minor driving tasks, such as lane changes, were evaluated. The distance of head restraint to posterior aspect of the head was measured continuously throughout the drive using an ultrasonic measurement system. The timing of specific tasks was documented using a video camera. The average head-to-restraint distance throughout the driving route was 78.1 mm (standard deviation [SD] 24.8 mm); this distance did not vary significantly between the global measures during various driving areas (residential, thruway, and highway). We observed that the head restraint backsets during right turns (93.6 mm; SD 34.8 mm) were significantly larger compared to the other driving tasks (p < .001). The 7 males and 7 females showed similar backset distances: 84.52 mm (SD 12.08) and 71.68 mm (SD 5.53), respectively (p = .0785). We observed that most subjects maintain a relatively consistent head-to-restraint distance throughout their driving route; 2 subjects adopted very large head restraint backset distances throughout their drive and 2 others adopted very small head restraint backset distances-this appears to reflect driver posture. Twelve of 14 subjects had average backset distances that exceed the National Highway Traffic Safety Administration and the Federal Motor Vehicle Safety Standard guidelines, indicating that most drivers may be at risk for whiplash-like disorders if exposed to a rear impact while driving. Of the monitored driving tasks, turning, especially right

Despite improvements in child passenger safety legislation and equipment, motor vehicle crashes (MVCs) continue to be the leading cause of death in children younger than 10 years. The objective of this study was to describe factors associated with restraint use in fatal MVC in children 0 year to 9 years old. The Fatality Analysis Reporting System, maintained by the National Highway Transportation Safety Administration, was used to obtain data on MVC fatalities from 2001 to 2010 in children 0 year to 9 years old. The main outcome was restraint use. Demographic information (age, sex, and race) and crash characteristics including vehicle type (sedan, van, truck, sports utility vehicle) and seat position in the vehicle were analyzed with the χ statistic to evaluate these factors for any restraint use compared with no restraint use in MVC fatalities. There were 7,625 MVC fatalities in children 0 year to 9 years old from 2001 to 2010.Among these fatalities, 4,041 (53%) had any restraint use. Front seat passengers accounted for 20.9% (1,595 of 7,625) of the fatalities. Children 0 year to 3 years old had a higher proportion of restraint use than children 4 years to 9 years old (p < 0.001). White children compared with black children had higher use of restraints (p < 0.001). Children riding in sedans/vans compared with sport utility vehicles/trucks and those riding in the rear seats of the vehicle compared with those in front seats were significantly more likely to use restraints (p < 0.001). Overall, only half of children 0 year to 9 years old who died in an MVC were wearing any child restraint in the vehicle, and 20% were sitting in the front seat. Continued efforts must be made to enforce legislation and educate the public about best practices regarding child passenger safety to improve proper restraint use and to decrease MVC fatalities in children.

Agmatine is an endogenous amine derived from decarboxylation of arginine catalysed by arginine decarboxylase. Agmatine is considered a novel neuromodulator and possesses neuroprotective properties in the central nervous system. The present study examined whether agmatine has neuroprotective effects against repeated restraint stress-induced morphological changes in rat medial prefrontal cortex and hippocampus. Sprague-Dawley rats were subjected to 6 h of restraint stress daily for 21 days. Immunohistochemical staining with β-tubulin III showed that repeated restraint stress caused marked morphological alterations in the medial prefrontal cortex and hippocampus. Stress-induced alterations were prevented by simultaneous treatment with agmatine (50 mg/kg/day, i.p.). Interestingly, endogenous agmatine levels, as measured by high-performance liquid chromatography, in the prefrontal cortex and hippocampus as well as in the striatum and hypothalamus of repeated restraint rats were significantly reduced as compared with the controls. Reduced endogenous agmatine levels in repeated restraint animals were accompanied by a significant increase of arginine decarboxylase protein levels in the same regions. Moreover, administration of exogenous agmatine to restrained rats abolished increases of arginine decarboxylase protein levels. Taken together, these results demonstrate that exogenously administered agmatine has neuroprotective effects against repeated restraint-induced structural changes in the medial prefrontal cortex and hippocampus. These findings indicate that stress-induced reductions in endogenous agmatine levels in the rat brain may play a permissive role in neuronal pathology induced by repeated restraint stress.

Castle, Nicholas G; Engberg, John

2009-11-01

Using a national longitudinal sample of nursing homes residents (N = 264,068), we examine whether physical restraint use contributes to subsequent physical or psychological health decline. The minimum data set, the on-line survey certification and recording system, and the area resource file were the data sources used. This data represented the period of 2004 and 2005. To control for the difference in characteristics between residents who were subsequently physically restrained and who were not, we use a propensity score matching method. For all outcomes examined (except depression), that is, behavior issues, cognitive performance, falls, walking dependence, activities of daily living, pressure ulcers, and contractures, were all significantly worse for restrained residents compared with matched residents who were not restrained. Physical restraint use represents poor clinical practice, and the benefits to residents of further reducing physical restraint use in nursing homes are substantial.

Obese older adults suffer foot pain and foot-related functional limitation.

PubMed

Mickle, Karen J; Steele, Julie R

2015-10-01

There is evidence to suggest being overweight or obese places adults at greater risk of developing foot complications such as osteoarthritis, tendonitis and plantar fasciitis. However, no research has comprehensively examined the effects of overweight or obesity on the feet of individuals older than 60 years of age. Therefore we investigated whether foot pain, foot structure, and/or foot function is affected by obesity in older adults. Three hundred and twelve Australian men and women, aged over 60 years, completed validated questionnaires to establish the presence of foot pain and health related quality of life. Foot structure (anthropometrics and soft tissue thickness) and foot function (ankle dorsiflexion strength and flexibility, toe flexor strength, plantar pressures and spatiotemporal gait parameters) were also measured. Obese participants (BMI >30) were compared to those who were overweight (BMI=25-30) and not overweight (BMI <25). Obese participants were found to have a significantly higher prevalence of foot pain and scored significantly lower on the SF-36. Obesity was also associated with foot-related functional limitation whereby ankle dorsiflexion strength, hallux and lesser toe strength, stride/step length and walking speed were significantly reduced in obese participants compared to their leaner counterparts. Therefore, disabling foot pain and altered foot structure and foot function are consequences of obesity for older adults, and impact upon their quality of life. Interventions designed to reduce excess fat mass may relieve loading of the foot structures and, in turn, improve foot pain and quality of life for older obese individuals.

Frontal sled tests comparing rear and forward facing child restraints with 1-3 year old dummies.

PubMed

Sherwood, C P; Crandall, J R

2007-01-01

Although most countries recommend transitioning children from rear facing (RF) to forward facing (FF) child restraints at one year of age, Swedish data suggests that RF restraints are more effective. The objective of this study was to compare RF and FF orientations in frontal sled tests. Four dummies (CRABI 12 mo, Q1.5, Hybrid III 3 yr, and Q3) were used to represent children from 1 to 3 years of age. Restraint systems tested included both 1) LATCH and 2) rigid ISOFIX with support leg designs. Rear facing restraints with support legs provided the best results for all injury measures, while RF restraints in general provided the lowest chest displacements and neck loads.

Sudden death due to sickle cell crisis during law enforcement restraint.

PubMed

Channa Perera, S D; Pollanen, Michael S

2007-07-01

We report a case of vaso-occlusive sickle cell crisis in a young schizophrenic man with undiagnosed sickle cell trait who was restrained. Prior to being restrained he had locked himself in his apartment for two days without food or water. He was subsequently restrained, and transferred to hospital while handcuffed to the stretcher. He died suddenly during restraint. At autopsy, there was acute vaso-occlusive sickle cell crisis associated with hypernatremic dehydration. There were no injuries present. We conclude that the death was due to vaso-occlusive sickle cell crisis secondary to dehydration. It is important for the forensic pathologist to remember that death may occur suddenly during restraint from an unexpected mechanism other than excited delirium leading to cardiac arrhythmia or restraint asphyxia.

Motivating drivers to correctly adjust head restraints: assessing effectiveness of three different interventions.

PubMed

Fockler, S K; Vavrik, J; Kristiansen, L

1998-11-01

Three types of driver educational strategies were tested to determine the most effective approach for motivating drivers to adjust their head restraints to the correct vertical position: (1) a human interactive personal contact with a member of an ICBC-trained head restraint adjustment team, (2) a passive video presentation of the consequences of correct and incorrect head restraint adjustment, and (3) an interactive three-dimensional kinetic model showing the consequences of correct and incorrect head restraint adjustment. An experimental pretest-posttest control group design was used. A different educational treatment was used in each of three lanes of a vehicle emissions testing facility, with a fourth lane with no intervention serving as a control group. Observational and self-reported data were obtained from a total of 1,974 vehicles entering and exiting the facility. The human intervention led to significantly more drivers actually adjusting their head restraints immediately after the intervention than the passive video or interactive kinetic model approaches, which were both no different from the control group. The human intervention was recommended as the most effective and was implemented successfully on a limited basis during 3 months of 1995 and again during 3 months of 1996.

Background Differences in foot structure are thought to be associated with differences in foot function during movement. Many foot pathologies are of a biomechanical nature and often associated with foot type. Fundamental to the understanding of foot pathomechanics is the question: do different foot types have distinctly different structure and function? Aim To determine if objective measures of foot structure and function differ between planus, rectus and cavus foot types in asymptomatic individuals. Methods Sixty-one asymptomatic healthy adults between 18 and 77 years old, that had the same foot type bilaterally (44 planus feet, 54 rectus feet, and 24 cavus feet), were recruited. Structural and functional measurements were taken using custom equipment, an emed-x plantar pressure measuring device, a GaitMatII gait pattern measurement system, and a goniometer. Generalized Estimation Equation modeling was employed to determine if each dependent variable of foot structure and function was significantly different across foot type while accounting for potential dependencies between sides. Post hoc testing was performed to assess pairwise comparisons. Results Several measures of foot structure (malleolar valgus index and arch height index) were significantly different between foot types. Gait pattern parameters were invariant across foot types. Peak pressure, maximum force, pressure-time-integral, force-time-integral and contact area were significantly different in several medial forefoot and arch locations between foot types. Planus feet exhibited significantly different center of pressure excursion indices compared to rectus and cavus feet. Conclusions Planus, rectus and cavus feet exhibited significantly different measures of foot structure and function. PMID:23107625

2018-04-03

In this study, we sought to accomplish the following objectives: to (1) calculate the percentage of children considered appropriately restrained across 8 criteria of increasing restrictiveness; (2) examine agreement between age- and size-based appropriateness criteria; (3) assess for changes in the percentage of children considered appropriately restrained by the 8 criteria between 2011 (shortly after updates to U.S. guidelines) and 2015. Data from 2 cross-sectional surveys of 928 parents of children younger than 12 years old (n = 591 in 2011, n = 337 in 2015) were analyzed in 2017. Child age, weight, and height were measured at an emergency department visit and used to determine whether the parent-reported child passenger restraint was considered appropriate according to 8 criteria. Age-based criteria were derived from Michigan law and U.S. Weight, height, and size-based criteria were derived from typical restraints available in the United States in 2007 and 2011. The percentage appropriate restraint use was calculated for each criterion. The kappa statistic was used to measure agreement between criteria. Change in appropriateness from 2011 to 2015 was assessed with chi-square statistics. Percentage appropriate restraint use varied from a low of 19% for higher weight limits in 2011 to a high of 91% for Michigan law in 2015. Agreement between criteria was slight to moderate. The lowest kappa was for Michigan law and higher weight limits in 2011 (κ = 0.06) and highest for U.S. guidelines and lower weight limits in 2011 (κ = 0.60). Percentage appropriate restraint use was higher in 2015 than 2011 for the following criteria: U.S. guidelines (74 vs. 58%, P < .001), lower weight (57 vs. 47%, P = .005), higher weight (25 vs. 19%, P = .03), greater height (39 vs. 26%, P < .001), and greater size (42 vs. 30%, P = .001). The percentage of children considered to be using an appropriate restraint varied substantially across criteria. Aligning the definition of

Algorithm for selection of optimized EPR distance restraints for de novo protein structure determination

PubMed Central

Kazmier, Kelli; Alexander, Nathan S.; Meiler, Jens; Mchaourab, Hassane S.

2010-01-01

A hybrid protein structure determination approach combining sparse Electron Paramagnetic Resonance (EPR) distance restraints and Rosetta de novo protein folding has been previously demonstrated to yield high quality models (Alexander et al., 2008). However, widespread application of this methodology to proteins of unknown structures is hindered by the lack of a general strategy to place spin label pairs in the primary sequence. In this work, we report the development of an algorithm that optimally selects spin labeling positions for the purpose of distance measurements by EPR. For the α-helical subdomain of T4 lysozyme (T4L), simulated restraints that maximize sequence separation between the two spin labels while simultaneously ensuring pairwise connectivity of secondary structure elements yielded vastly improved models by Rosetta folding. 50% of all these models have the correct fold compared to only 21% and 8% correctly folded models when randomly placed restraints or no restraints are used, respectively. Moreover, the improvements in model quality require a limited number of optimized restraints, the number of which is determined by the pairwise connectivities of T4L α-helices. The predicted improvement in Rosetta model quality was verified by experimental determination of distances between spin labels pairs selected by the algorithm. Overall, our results reinforce the rationale for the combined use of sparse EPR distance restraints and de novo folding. By alleviating the experimental bottleneck associated with restraint selection, this algorithm sets the stage for extending computational structure determination to larger, traditionally elusive protein topologies of critical structural and biochemical importance.

Foot Placement Modulation Diminishes for Perturbations Near Foot Contact.

PubMed

Vlutters, Mark; Van Asseldonk, Edwin H F; van der Kooij, Herman

2018-01-01

Whenever a perturbation occurs during walking we have to maintain our balance using the recovery strategies that are available to us. Foot placement adjustment is often considered an important recovery strategy. However, because this strategy takes time it is likely a poor option if the foot is close to contact at the instant a perturbation occurs. The main goal of this study is to gain a better understanding of how humans deal with balance perturbations during walking if foot placement adjustments are constrained by time. Ten healthy subjects walked on an instrumented treadmill and received mediolateral and anteroposterior pelvis perturbations at various instances during the single support phase. The results show that foot placement modulation in the first recovery step following anteroposterior perturbations is fairly invariant of the perturbation magnitude and direction, regardless of the onset instance. For mediolateral perturbations, foot placement adjustments strongly modulate with the perturbation magnitude and direction, but these effects diminish when the perturbation onset is closer to the instant of foot contact. For most perturbations the first recovery step was consistent across subjects for all onset instances. However, in the second step various strategies arose that were not consistent across subjects, nor within subjects, especially for perturbations applied close to foot contact. Despite these different strategies, the COP location following foot contact strongly related to the COM velocity throughout these strategies. The results show that humans have various ways to compensate for limited availability of a foot placement strategy, with strategy selection highly dependent on the instant during the gait phase at which the perturbation is applied.

The psychiatric emergency room is a dynamic and sometimes volatile environment. Its design may be an important variable in patient care, but most design decisions are based on models of thought and treatment with a minimal evidence base. The concept of open design, increasing access of patients to nursing staff, for inpatient psychiatric units has recently gained widespread acceptance, despite a dearth of empirical data. We examined rates of seclusion and restraint before and after a design change that reduced the openness of the unit in a dedicated emergency psychiatric service in a general university hospital. Quality assurance data regarding the census, occurrence of assaults, and the use of seclusion and restraint were queried. Two independent analyses utilizing a test of proportional data were performed to replicate the findings. After placement of a door to restrict patients' access to the waiting area of the unit, the rate of the use of seclusion and restraint went from 0.03 (44/777) to 0.0185 (27/1,514; z = 2.02, p < .04). Replication over a separate time period saw reduction from 0.029 (67/2,277) to 0.018 (44/2,431), z = 2.44, p < .02). A design change that reduced the openness of the unit resulted in the reduction of seclusion and restraint. © The Author(s) 2015.

Optimising product advice based on age when design criteria are based on weight: child restraints in vehicles.

PubMed

Anderson, R W G; Hutchinson, T P

2009-03-01

The motivation for this paper is the high rate of inappropriate child restraint selection in cars that is apparent in published surveys of child restraint use and how the public health messages promoting child restraints might respond. Advice has increasingly been given solely according to the child's weight, while many parents do not know the weight of their children. A common objection to promoting restraint use based on the age of the child is the imprecision of such advice, given the variation in the size of children, but the magnitude of the misclassification such advice would produce has never been estimated. This paper presents a method for estimating the misclassification of children by weight, when advice is posed in terms of age, and applies it to detailed child growth data published by the Centers for Disease Control and Prevention. In Australia, guidelines instructing all parents to promote their children from an infant restraint to a forward-facing child seat at 6 months, and then to a belt-positioning booster at 4 years, would mean that 5% of all children under the age of 6 years would be using a restraint not suited to their weight. Coordination of aged-based advice and the weight ranges chosen for the Australian Standard on child restraints could reduce this level of misclassification to less than 1%. The general method developed may also be applied to other aspects of restraint design that are more directly relevant to good restraint fit.

Modern super agile fighter aircraft are capable of producing an increasing multiaxial acceleration environment which can adversely affect the pilot. An evaluation of the performance of the restraint system during flight maneuvers will benefit restraint designs and, thus, the safety of pilots. A finite element model of a mannequin with PCU-15/P harness restraint was used in this study to investigate how the factors, such as strap material stiffness, friction, and belt tension, affect the performance of restraint systems during impact along the -Gx, -Gy, and -Gz directions. The corresponding maximum displacement of the mannequin's torso was computed. The mannequin moved beyond 74 mm sideways. The change in friction coefficient (FC) from 0.1 to 0.4 decreased the displacement of the lower torso by less than 6.7%. The displacement of the torso decreased as the stiffness of the strap or tension increased. Displacement decreased by 9.3%, 6.0%, and 2.7% for the lower torso under the Gx impact, as the tightening force increased from 20 N to 80 N gradually. However, this changed slightly when the stiffness arrived at 1 E or the tension increased to 60 N. PCU-15/P harness has the poorest performance during side impact and friction plays an unimportant role in affecting its performance. The stiffness of the webbing used in the PCU-15/P harness is sufficiently high. The lap belt has more effect on limiting the movement of the pilot than the shoulder straps, and a tension of 60 N during the adjustment may be enough for conventional flight maneuvers.

Adrenocortical response in rats subjected to a stress of restraint by immobilization whether accompanied by hypothermia or not

Buchel, L.; Prioux-Guyonneau, M.; Libian, L.

1980-01-01

The restraint associated with hypothermia which increases the adrenal activity in rats was investigated. In rats with nomothermia or light hypothermia, the plasma and adrenal corticosterone levels increase at least threefold whatever the duration of restraint. Their return to normal values depends on the duration of the restraint. Exposure to cold produces in free rats a light hypothermia with an increase of the plasma and adrenal corticosterone levels, and in restraint animals an important hypothermia which does not potentiate the stimulation of adrenocortical activity induced by the restraint alone.

Negative affect and dietary restraint are key predictors of binge eating, yet less is known about the impact of social factors on binge eating. The study sought to replicate and extend research on the relationships between negative affect, dietary restraint, perceived social isolation and binge eating using a daily diary methodology. College women (N = 54) completed measures of dietary restraint, negative affect, perceived social isolation, and binge eating daily for 14 days. Participants completed the measures nightly each day. A series of generalized estimating equations showed that dietary restraint was associated with less binge eating while controlling for negative affect and for perceived social isolation separately. Negative affect and perceived social isolation were associated with greater binge eating while controlling for restraint in separate analyses, but only perceived social isolation was significant when modeled simultaneously. All two-way interactions between negative affect, dietary restraint, and perceived social isolation predicting binge eating were nonsignificant. This study furthers our understanding of predictors of binge eating in a nonclinical sample. Specifically, these data suggest perceived social isolation, negative affect, and dietary restraint are important variables associated with binge eating in daily life and warrant further research.

Physical restraints are used to enhance the safety of patients and to avoid injury. However, physical restraints may cause injuries if improperly used or if they are used in the absence of continuous monitoring. Nursing staff who use physical restraints often lack sufficient related knowledge, which may increase the risk to patient safety. This study investigates the impact of an in-service education program for nursing staff that is designed to improve physical-restraint-related knowledge, attitudes, behaviors, and techniques. A pretest-posttest design and a quasi-experimental method were employed to evaluate the effectiveness of the in-service education program. One hundred thirty-six nursing staff from four adult intensive care units (ICUs), including two medical ICUs and two surgical ICUs, in a medical center in central Taiwan were enrolled as participants. The experimental group (EG) and the control group (CG) were composed of patients from one randomly assigned medical ICU and one randomly assigned surgical ICU each. The pretest data on physical-restraint-related knowledge, attitudes, behaviors, and techniques were collected before the in-service education program. The EG received 2 hours of classroom education on guidelines and techniques related to physical restraints. The posttest data for the two groups were collected a month after implementation of the in-service education program. General Estimation Equation was used to measure and analyze the data repeatedly. The posttest scores of the EG for knowledge and technique were significantly higher than the pretest scores (p < .0001). However, the posttest scores of the EG for attitudes and behaviors did not significantly differ from the pretest scores. In-service education for physical restraints enhances relevant knowledge and techniques but does not significantly affect attitudes or behaviors. Correct implementation of physical restraints not only promotes the quality of nursing care for patients in the

Pasireotide is a new-generation somatostatin analog that acts through binding to multiple somatostatin receptor subtypes. Studies have shown that pasireotide induces hyperglycemia, reduces glucocorticoid secretion, alters neurotransmission, and potentially affects stress responses typically manifested as hyperglycemia and increased corticosterone secretion. This study specifically aimed to evaluate whether pasireotide treatment modifies glucose and costicosterone secretion in response to acute restraint stress. Male Holtzman rats of 150-200 g were treated with pasireotide (10 µg/kg/day) twice-daily for two weeks or vehicle for the same period. Blood samples were collected at baseline and after 5, 10, 30, and 60 min of restraint stress. The three experimental groups comprised of vehicle + restraint (VEHR), pasireotide + restraint (PASR), and pasireotide + saline (PASNR). Following pasireotide treatment, no significant differences in baseline glucose and corticosterone levels were observed among the three groups. During restraint, hyperglycemia was observed at 10 min (p < .01 for both comparisons), peaked at 30 min (p < .01 for both comparisons) and showed higher 60 min areas under glucose curves in the VEHR and PASR stressed groups when compared to the non-stressed PASNR group (p < .05 for both comparisons). Restraint also increased corticosterone secretion in the VEHR and PASR stressed groups at 5 min (p < .01 for both comparisons), and peaked at 30 min (p < .01 for both comparisons) with corresponding higher 60 min areas under corticosterone curves when compared to the non-stressed PASNR group (p < .01 for both comparisons). In conclusion, pasireotide treatment does not modify hyperglycemic- and corticosterone-restraint stress responses, thus preserving acute stress regulation.

SKITTER foot design

1987-01-01

A mechanical design team was formed to design a foot for the lunar utility vehicle SKITTER. The primary design was constrained to be a ski pole design compatible with the existing femur-tibia design legs. The lunar environment had several important effects on the foot design. Three materials were investigated for the SKITTER foot: aluminum alloys, cold worked stainless steel alloys, and titanium alloys. Thin film coatings were investigated as a method of wear reduction for the foot. The performance of the foot is dependent on the action of the legs. The range of motion for the legs was determined to be vertical to 15 degrees above horizontal. An impact analysis was performed for the foot movement, but the results were determined to be inconclusive due to unknown soil parameters. The initial foot design configuration consisted of an annulus attached to the pointed pole. The annulus was designed to prevent excess sinkage. Later designs call for a conical shaped foot with a disk at the point of the tibia attachment. The conical design was analyzed for strength and deflection by two different approaches. A deformable body analysis was performed for the foot under crane load in crane position, and also under actuator load in the vertical position. In both cases, the deflection of the foot was insignificant and the stresses well below the strength of the titanium alloy.

A national approach to diabetes foot risk stratification and foot care.

PubMed

Leese, G P; Stang, D; Pearson, D W

2011-08-01

The Scottish Diabetes Foot Action Group (SDG) has developed and introduced a national strategy plan for diabetic foot care across Scotland. This has involved the implementation of an evidence-based national foot screening and risk stratification programme that has already covered 61% of the population in just the first two years. Nationally agreed patient information foot leaflets and professional education material have been introduced, and a consensus for antibiotic use in the diabetic foot has been published. Information on multidisciplinary specialist foot services has been collected, indicating that 58% of Health Board areas have consultants with dedicated sessions in their job plan to a foot clinic, and 42% had integrated orthotic involvement. The SDG aims to increase these figures. Work has been undertaken to support local podiatry networks and improve communication between the specialist centre and the community. At a national level the SDG is working with Foot in Diabetes UK (FDUK) to recognize key podiatry skills by developing core competencies and a competency framework for the diabetes podiatrist and diabetes orthotist. The annual Scottish Diabetes Survey indicates some improvement in amputation rates with prevalence decreasing from 0.8% to 0.5%, and improved recording of foot ulceration at a national level. This national strategy has helped highlight the importance and difficulties facing diabetes foot care and should help to continue to improve the quality of care of people with diabetes who have foot-related problems.

The aim of this study was to explore nurses' and physicians' perspectives on and reasoning about the use of restraint during medical procedures on newly admitted preschoolers in somatic hospital care. We analysed qualitative data from individual interviews with a video recall session at the end with seven physicians and eight nurses. They had earlier participated in video recorded peripheral vein cannulations on preschool children. The data were collected between May 2012 and May 2013 at a paediatric hospital unit in Norway. The analysis resulted in three main themes: (1) disparate views on the concept of restraint and restraint use (2), ways to limit the use of physical restraint and its negative consequences, and (3) experience with the role of parents and their influence on restraint. Perspectives from both healthcare professions were represented in all the main themes and had many similarities. The results of this study may facilitate more informed and reflective discussions of restraint and contribute to higher awareness of restraint in clinical practice. Lack of guidance and scientific attention to restraint combined with conflicting interests and values among healthcare providers may result in insecurity, individual dogmatism, and a lack of shared discussions, language, and terminology.

The Effect of Manual Restraint on Physiological Parameters in Barred Owls ( Strix varia ).

Manual restraint is commonly necessary when working with avian species in medical, laboratory, and field settings. Despite their prevalence, little is known about the stress response in raptorial bird species. To further understand the effect of restraint on the stress response in birds of prey, 12 barred owls ( Strix varia ) were manually restrained for 15 minutes. Physiological parameters (cloacal temperature, respiratory rate, heart rate) were followed over time and recorded at defined points during the restraint period. Heart rate decreased significantly over the restraint period by a mean ± SD of -73 ± 46 beats/min. Respiratory rate also decreased significantly (median: -11 breaths/min, interquartile range: -8 to -18). Cloacal temperature increased significantly over time in manually restrained owls (median: +1.5°C [+2.7°F], interquartile range: 1.3°C-2.1°C [2.3°F-3.8°F]). This study is the first to document stress hyperthermia in an owl species. Similar to another raptorial bird, the red-tailed hawk ( Buteo jamaicensis ), both heart rate and respiratory rate decreased and cloacal temperature increased over time in restrained barred owls. Barred owls appear to cope differently to restraint stress when compared to psittacine species.

Maximum-likelihood X-ray macromolecular structure refinement in BUSTER has been extended with restraints facilitating the exploitation of structural similarity. The similarity can be between two or more chains within the structure being refined, thus favouring NCS, or to a distinct 'target' structure that remains fixed during refinement. The local structural similarity restraints (LSSR) approach considers all distances less than 5.5 Å between pairs of atoms in the chain to be restrained. For each, the difference from the distance between the corresponding atoms in the related chain is found. LSSR applies a restraint penalty on each difference. A functional form that reaches a plateau for large differences is used to avoid the restraints distorting parts of the structure that are not similar. Because LSSR are local, there is no need to separate out domains. Some restraint pruning is still necessary, but this has been automated. LSSR have been available to academic users of BUSTER since 2009 with the easy-to-use -autoncs and -target target.pdb options. The use of LSSR is illustrated in the re-refinement of PDB entries 5rnt, where -target enables the correct ligand-binding structure to be found, and 1osg, where -autoncs contributes to the location of an additional copy of the cyclic peptide ligand.

Most trauma centers incorporate mechanistic criteria (MC) into their algorithm for trauma team activation (TTA). We hypothesized that characteristics of the crash are less reliable than restraint status in predicting significant injury and the need for TTA. We identified 271 patients (age, <15 y) admitted with a diagnosis of motor vehicle crash. Mechanistic criteria and restraint status of each patient were recorded. Both MC and MC plus restraint status were evaluated as separate measures for appropriately predicting TTA based on treatment outcomes and injury scores. Improper restraint alone predicted a need for TTA with an odds ratios of 2.69 (P = .002). MC plus improper restraint predicted the need for TTA with an odds ratio of 2.52 (P = .002). In contrast, the odds ratio when using MC alone was 1.65 (P = .16). When the 5 MC were evaluated individually as predictive of TTA, ejection, death of occupant, and intrusion more than 18 inches were statistically significant. Improper restraint is an independent predictor of necessitating TTA in this single-institution study. Copyright © 2012 Elsevier Inc. All rights reserved.

Coercion remains a central aspect of many people’s mental healthcare. It can include the use of legislation to restrict freedoms, the use of physical restraint, the restriction of freedom of movement and/or association, and the forced or covert administration of medication. There is good evidence that the use of such measures can traumatise service users. This article reports the findings of a survey of service users regarding their experiences of coercion and restraint and embeds this in the wider international and institutional environment.

The relationship between dietary restraint and binge eating: Examining eating-related self-efficacy as a moderator.

PubMed

Linardon, Jake

2018-05-01

Although dietary restraint has been shown to be a robust predictor of binge eating among women, many women report elevated levels of dietary restraint but do not concurrently exhibit symptoms of binge eating. Moderating variables could therefore interact with dietary restraint to affect its relation to binge eating. One potential factor that may attenuate this relationship is eating-related self-efficacy, defined as the tendency to feel confident in the ability to control eating behaviour under a diverse set of circumstances (e.g., under negative affect, social conflicts). This cross-sectional study examined whether eating-related self-efficacy moderated the relationship between flexible (i.e., a graded approach to dieting, defined by behaviour such as taking smaller servings to regulate body weight, yet still enjoying a variety of foods) and rigid restraint (i.e., an all-or-none approach to eating, characterised by inflexible diet rules) and binge eating. Data were analysed from 237 women. Greater levels of rigid restraint, flexible restraint, and a poorer self-efficacy were shown to predict unique variance in binge eating severity. A significant interaction effect was observed between flexible (but not rigid) restraint and self-efficacy scores on binge eating. Contrary to expectations, however, the flexible restraint-binge eating relationship was largest for those with moderate to strong self-efficacy, and was non-significant for those with poor self-efficacy. Overall, findings suggest that different mechanisms may be operating to maintain binge eating in those with varying levels of eating-related self-efficacy. Copyright © 2018 Elsevier Ltd.

In a clinical setting, patients have been observed to complain of discomfort and to discontinue treatment because of chemotherapy-induced peripheral neuropathy (CIPN), but few data exist regarding the quality of life in these patients in Korea. The purpose of this quasi-experimental study was to analyze the effects of foot bathing and massage in patients with CIPN. Subjects included 48 patients with CIPN, who were hospitalized in C University Hospital. The subjects were alternately assigned to 1 of 2 groups according to their registration order. The interventions consisted of 8 treatments of foot bathing or massage over a period of 2 weeks, at 30 minutes per session, every other day. The foot skin temperature increased significantly in the foot bathing group, whereas it decreased significantly in the massage group. Quality of life was significantly increased in the foot bathing group, whereas it was significantly decreased in the massage group. Although foot bathing and foot massage are both supportive care techniques for CIPN patients, foot bathing was more effective than foot massage on skin temperature, grade of neurotoxicity, and quality of life. Additional well-designed studies are recommended, so that the effectiveness of foot bathing and foot massage is confirmed. Foot bathing is more useful as supportive care with respect to nonpharmacologic interventions for alleviating CIPN and promoting the quality of life in cancer patients.

Weight loss in rats exposed to repeated acute restraint stress is independent of energy or leptin status.

Acute release of corticotropin-releasing factor (CRF) during repeated restraint (3-h restraint on each of 3 days) causes temporary hypophagia but chronic suppression of body weight in rats. Here we demonstrated that a second bout of repeated restraint caused additional weight loss, but continuing restraint daily for 10 days did not increase weight loss because the rats adapted to the stress. In these two studies serum leptin, which suppresses the endocrine response to stress, was reduced in restrained rats. Peripheral infusion of leptin before and during restraint did not prevent stress-induced weight loss, although stress-induced corticosterone release was suppressed. Restrained rats were hyperthermic during restraint, but there was no evidence that fever or elevated free interleukin-6 caused the sustained reduction in weight. Restraining food-restricted rats caused a small but significant weight loss. Food-restricted rats fed ad libitum after the end of restraint showed a blunted hyperphagia and slower rate of weight regain than their controls. These results indicate that repeated acute stress induces a chronic change in weight independent of stress-induced hypophagia and may represent a change in homeostasis initiated by repeated acute activation of the central CRF system.

Cervical spine injuries sustained in rear-end crashes cost at least $7 billion in insurance claims annually in the United States alone. When positioned correctly, head restraint systems have been proven effective in reducing the risk of whiplash associated disorders. Chiropractors should be knowledgeable about the correct use of head restraint systems to educate their patients and thereby prevent or minimize such injuries. The primary objective of this study was to determine the prevalence of correct positioning of car seat head restraints among the interns at our institution. The secondary objective was to determine the same chiropractic interns' knowledge of the correct positioning of car seat head restraints. It was hypothesized that 100 percent of interns would have their head restraint correctly positioned within an acceptable range and that all interns would possess the knowledge to instruct patients in the correct positioning of head restraints. Cross-sectional study of a convenient sample of 30 chiropractic interns from one institution. Interns driving into the parking lot of our health center were asked to volunteer to have measurements taken and to complete a survey. Vertical and horizontal positions of the head restraint were measured using a beam compass. A survey was administered to determine knowledge of correct head restraint position. The results were recorded, entered into a spreadsheet, and analyzed. 13.3 percent of subjects knew the recommended vertical distance and only 20 percent of subjects knew the recommended horizontal distance. Chi Square analyses substantiated that the majority of subjects were unaware of guidelines set forth by the National Highway Traffic Safety Administration (NHTSA) for the correct positioning of the head restraint (chi(2) (vertical) = 16.13, chi(2) (horizontal) = 10.80, p <.05). Only 6.7 percent of the subjects positioned their head restraint at the vertical distance of 6 cm or less (p <.05). However, 60 percent of

Portable Bladder Ultrasound

2006-01-01

Executive Summary Objective The aim of this review was to assess the clinical utility of portable bladder ultrasound. Clinical Need: Target Population and Condition Data from the National Population Health Survey indicate prevalence rates of urinary incontinence are 2.5% in women and 1.4 % in men in the general population. Prevalence of urinary incontinence is higher in women than men and prevalence increases with age. Identified risk factors for urinary incontinence include female gender, increasing age, urinary tract infections (UTI), poor mobility, dementia, smoking, obesity, consuming alcohol and caffeine beverages, physical activity, pregnancy, childbirth, forceps and vacuum-assisted births, episiotomy, abdominal resection for colorectal cancer, and hormone replacement therapy. For the purposes of this review, incontinence populations will be stratified into the following; the elderly, urology patients, postoperative patients, rehabilitation settings, and neurogenic bladder populations. Urinary incontinence is defined as any involuntary leakage of urine. Incontinence can be classified into diagnostic clinical types that are useful in planning evaluation and treatment. The major types of incontinence are stress (physical exertion), urge (overactive bladder), mixed (combined urge and stress urinary incontinence), reflex (neurological impairment of the central nervous system), overflow (leakage due to full bladder), continuous (urinary tract abnormalities), congenital incontinence, and transient incontinence (temporary incontinence). Postvoid residual (PVR) urine volume, which is the amount of urine in the bladder immediately after urination, represents an important component in continence assessment and bladder management to provide quantitative feedback to the patient and continence care team regarding the effectiveness of the voiding technique. Although there is no standardized definition of normal PVR urine volume, measurements greater than 100 mL to 150 m

Bupleurum falcatum prevents depression and anxiety-like behaviors in rats exposed to repeated restraint stress.

2012-03-01

Previous studies have demonstrated that repeated restraint stress in rodents produces increases in depression and anxietylike behaviors and alters the expression of corticotrophinreleasing factor (CRF) in the hypothalamus. The current study focused on the impact of Bupleurum falcatum (BF) extract administration on repeated restraint stress-induced behavioral responses using the forced swimming test (FST) and elevated plus maze (EPM) test. Immunohistochemical examinations of tyrosine hydroxylase (TH) expression in rat brain were also conducted. Male rats received daily doses of 20, 50, or 100 mg/kg (i.p.) BF extract for 15 days, 30 min prior to restraint stress (4 h/day). Hypothalamicpituitary- adrenal axis activation in response to repeated restraint stress was confirmed base on serum corticosterone levels and CRF expression in the hypothalamus. Animals that were pre-treated with BF extract displayed significantly reduced immobility in the FST and increased open-arm exploration in the EPM test in comparison with controls. BF also blocked the increase in TH expression in the locus coeruleus of treated rats that experienced restraint stress. Together, these results demonstrate that BF extract administration prior to restraint stress significantly reduces depression and anxiety-like behaviors, possibly through central adrenergic mechanisms, and they suggest a role for BF extract in the treatment of depression and anxiety disorders.

Attitudes of nurses towards the use of physical restraints in geriatric care: a systematic review of qualitative and quantitative studies.

To examine nurses' attitudes towards the use of physical restraints in geriatric care. Systematic review and synthesis of qualitative and quantitative studies. The following databases were searched: Medline, CINAHL, EMBASE, Psyndex, PsychInfo, Social SciSearch, SciSearch, Forum Qualitative Social Research (1/1990 to 8/2013). We performed backward and forward citation tracking to all of the included studies. We included in the present review all qualitative and quantitative studies in English and German that investigated nurses' attitudes towards the use of physical restraints in geriatric care. Two independent reviewers selected the studies for inclusion and assessed the study quality. We performed a thematic synthesis for the qualitative studies and a content analysis of the questionnaires' items as well as a narrative synthesis for the quantitative surveys. We included 31 publications in the review: 20 quantitative surveys, 10 qualitative and 1 mixed-method study. In the qualitative studies, nurses' attitudes towards the use of physical restraints in geriatric care were predominately characterised by negative feelings towards the use of restraints; however, the nurses also described a perceived need for using restraints in clinical practice. This discrepancy led to moral conflicts, and nurses described several strategies for coping with these conflicts when restraints were used. When nurses were in doubt regarding the use of restraints, they decided predominantly in favour of using restraints. The results of the quantitative surveys were inconsistent regarding nurses' feelings towards the use of restraints in geriatric care. Prevention of falls was identified as a primary reason for using restraints. However, the items of the questionnaires focussed primarily on the reasons for the use of restraints rather than on the attitudes of nurses. Despite the lack of evidence regarding the benefits of restraints and the evidence on the adverse effects, nurses often

Indoor Pedestrian Navigation Using Foot-Mounted IMU and Portable Ultrasound Range Sensors

Many solutions have been proposed for indoor pedestrian navigation. Some rely on pre-installed sensor networks, which offer good accuracy but are limited to areas that have been prepared for that purpose, thus requiring an expensive and possibly time-consuming process. Such methods are therefore inappropriate for navigation in emergency situations since the power supply may be disturbed. Other types of solutions track the user without requiring a prepared environment. However, they may have low accuracy. Offline tracking has been proposed to increase accuracy, however this prevents users from knowing their position in real time. This paper describes a real time indoor navigation system that does not require prepared building environments and provides tracking accuracy superior to previously described tracking methods. The system uses a combination of four techniques: foot-mounted IMU (Inertial Motion Unit), ultrasonic ranging, particle filtering and model-based navigation. The very purpose of the project is to combine these four well-known techniques in a novel way to provide better indoor tracking results for pedestrians. PMID:22164034

Restraint stress and social defeat: What they have in common.

Motta, Simone Cristina; Canteras, Newton Sabino

2015-07-01

Bob Blanchard was a great inspiration for our studies on the neural basis of social defense. In the present study, we compared the hypothalamic pattern of activation between social defeat and restraint stress. As important stress situations, both defeated and immobilized animals displayed a substantial increase in Fos in the parvicellular part of the paraventricular nucleus,mostly in the region that contains the CRH neurons. In addition, socially defeated animals, but not restrained animals, recruited elements of the medial hypothalamic conspecific-responsive circuit, a region also engaged in other forms of social behavior. Of particular interest, both defeated and immobilized animals presented a robust increase in Fos expression in specific regions of the lateral hypothalamic area (i.e., juxtaparaventricular and juxtadorsomedial regions) likely to convey septo-hippocampal information encoding the environmental boundary restriction observed in both forms of stress, and in the dorsomedial part of the dorsal premammillary nucleus which seems to work as a key player for the expression of, at least, part of the behavioral responses during both restraint and social defeat. These results indicate interesting commonalities between social defeat and restraint stress, suggesting, for the first time, a septo-hippocampal–hypothalamic path likely to respond to the environmental boundary restriction that may act as common stressor component for both types of stress. Moreover, the comparison of the neural circuits mediating physical restraint and social defense revealed a possible path for encoding the entrapment component during social confrontation.

Restraint use for children in automobiles is mandated in every state, but injury patterns are unknown. Although use of pediatric retraints is associated with reducing morbidity and mortality, the injury distribution for specific anatomic sites may be altered in restrained vs unrestrained children. Review of trauma registry data, medical records, and autopsy findings. Urban level I trauma center and tertiary care children's hospital. All children aged 6 years or younger who were in motor vehicle collisions from June 1, 1990, through March 31, 1997. Age, weight, restraint use and type, collision data, Injury Severity Score (ISS), injury type, and outcome. We included 600 children. The restrained group showed a reduction in severe injuries for every anatomic site and had a lower mean ISS, fewer injuries, and more uninjured children. The restrained group also had a reduction in the incidence of hollow- and solid-organ abdominal injuries. Age-appropriate restraint devices decrease mortality and reduce the incidence of significant injury in motor vehicle collisions for all anatomic sites in young children. In contrast to injuries attributed to restraint use in adults, specific restraint-related injury patterns were not seen in children.

Conformation-dependent restraints for polynucleotides: I. Clustering of the geometry of the phosphodiester group

2016-01-01

The refinement of macromolecular structures is usually aided by prior stereochemical knowledge in the form of geometrical restraints. Such restraints are also used for the flexible sugar-phosphate backbones of nucleic acids. However, recent highly accurate structural studies of DNA suggest that the phosphate bond angles may have inadequate description in the existing stereochemical dictionaries. In this paper, we analyze the bonding deformations of the phosphodiester groups in the Cambridge Structural Database, cluster the studied fragments into six conformation-related categories and propose a revised set of restraints for the O-P-O bond angles and distances. The proposed restraints have been positively validated against data from the Nucleic Acid Database and an ultrahigh-resolution Z-DNA structure in the Protein Data Bank. Additionally, the manual classification of PO4 geometry is compared with geometrical clusters automatically discovered by machine learning methods. The machine learning cluster analysis provides useful insights and a practical example for general applications of clustering algorithms for automatic discovery of hidden patterns of molecular geometry. Finally, we describe the implementation and application of a public-domain web server for automatic generation of the proposed restraints. PMID:27521371

Using Child Age or Weight in Selecting Type of In-Vehicle Restraint: Implications For Promotion And Design

PubMed Central

Anderson, Robert W. G.; Hutchinson, T. Paul; Edwards, Sally A.

2007-01-01

A survey of motor vehicle child restraint use found around 28% of children under the age of six using weight-inappropriate restraints. Many parents did not know when a child was likely to outgrow a booster seat nor the weight of their child, but they did know the child’s age. Anthropometric data show that, if advice on restraint transition, given solely in terms of age (6 months, 4 years, 8 years) were followed in Australia, incorrect restraint selection would occur in 5% of children under the age of six. Further analysis suggests how rewriting the Standard could reduce this number. We present an argument for placing age-based transitions at the heart of the strategy to improve child restraint compliance. This may be superior to one based on the child’s weight or other anthropometric measurement. Our argument may be summarized as follows: 1 Age-based rules for selecting child restraints are simple, require less information to be retained, and might be more natural criteria for parents. They might have a greater chance of being adopted as norms, and of encouraging good peer cues. Anthropometric rules, on the other hand, assume that parents know the current dimensions of their children and have the tools at their disposal to measure these dimensions. 2 The consequences of age-based promotion for the proportion of children in a restraint suitable for their weight can be estimated for alternative regulatory frameworks. We will report such Calculations below and show that this rate can potentially be very high. The rate would be even higher if child restraint design standards were drafted with age-based transitions in mind. Age-based transitions imply restraint specifications (weight and height limits) that can be determined from anthropometric survey data. 3 Such standards would necessarily imply overlapping anthropometric ranges for the different types of restraint. However, we emphasize that these overlaps would exist to facilitate age-based transitions, not to

the purpose of this project was to evaluate two systems for restraining the movement of 345kV high-pressure oil-filled (HPOF) cable joints during load cycling. Problems with joints and adjacent cables due to thermomechanical bending (TMB) experienced by the Consolidated Edison Company of New York and Public Service Electric Gas Company of New Jersey are reviewed. Some approaches to reducing or preventing TMB induced damage to HPOF pipe type cable joints are discussed. The design and operation of a special test apparatus for simulating TMB effects under laboratory conditions is described. One of the two joint restraint systems evaluated under thismore » project was developed by PSE G and employed wedging devices, which could be retrofitted into existing installations, that limited the longitudinal movement of the joints during load cycling. The other system developed by Pirelli Cable Corporation applied the restraining force to the cylindrical portion of the hand applied joint insulation by means of support spiders and steel rods attached to the reducer faces. The test results show that the PSE G restraint system can effectively limit joint longitudinal movement while causing a minimal amount of mechanical disturbance to the joint stress cones. The test results obtained with the PCC system are inconclusive and indicate that further refinement and testing are required to demonstrate the effectiveness of this promising joint restraint system.« less

Highly Portable, Sensor-Based System for Human Fall Monitoring.

Falls are a very dangerous situation especially among elderly people, because they may lead to fractures, concussion, and other injuries. Without timely rescue, falls may even endanger their lives. The existing optical sensor-based fall monitoring systems have some disadvantages, such as limited monitoring range and inconvenience to carry for users. Furthermore, the fall detection system based only on an accelerometer often mistakenly determines some activities of daily living (ADL) as falls, leading to low accuracy in fall detection. We propose a human fall monitoring system consisting of a highly portable sensor unit including a triaxis accelerometer, a triaxis gyroscope, and a triaxis magnetometer, and a mobile phone. With the data from these sensors, we obtain the acceleration and Euler angle (yaw, pitch, and roll), which represents the orientation of the user's body. Then, a proposed fall detection algorithm was used to detect falls based on the acceleration and Euler angle. With this monitoring system, we design a series of simulated falls and ADL and conduct the experiment by placing the sensors on the shoulder, waist, and foot of the subjects. Through the experiment, we re-identify the threshold of acceleration for accurate fall detection and verify the best body location to place the sensors by comparing the detection performance on different body segments. We also compared this monitoring system with other similar works and found that better fall detection accuracy and portability can be achieved by our system.

Furthermore, the fall detection system based only on an accelerometer often mistakenly determines some activities of daily living (ADL) as falls, leading to low accuracy in fall detection. We propose a human fall monitoring system consisting of a highly portable sensor unit including a triaxis accelerometer, a triaxis gyroscope, and a triaxis magnetometer, and a mobile phone. With the data from these sensors, we obtain the acceleration and Euler angle (yaw, pitch, and roll), which represents the orientation of the user’s body. Then, a proposed fall detection algorithm was used to detect falls based on the acceleration and Euler angle. With this monitoring system, we design a series of simulated falls and ADL and conduct the experiment by placing the sensors on the shoulder, waist, and foot of the subjects. Through the experiment, we re-identify the threshold of acceleration for accurate fall detection and verify the best body location to place the sensors by comparing the detection performance on different body segments. We also compared this monitoring system with other similar works and found that better fall detection accuracy and portability can be achieved by our system. PMID:28902149

"Physical restraint" formerly used as a measure of protection for psychiatric patients is now widely used. However, existing studies showed that physical restraint not only has inadequate effect of protection but also has negative effects on residents. To analyzes the impact of educational program on the physical restraint use in long-term care facilities. A systematic review with meta-analysis and meta-regression. Eight databases, including Cochrane Library, ProQuest, PubMed, EMBASE, EBSCO, Web of Science, Ovid Medline and Physiotherapy Evidence Database (PEDro), were searched up to January 2017. Eligible studies were classified by intervention and accessed for quality using the Quality Assessment Tool for quantitative studies. Sixteen research articles were eligible in the final review; 10 randomize control trail studies were included in the analysis. The meta-analysis revealed that the use of physical restraint was significantly less often in the experimental (education) group (OR = 0.55, 95% CI: 0.39 to 0.78, p < 0.001) compared to the control group. Meta-regression revealed the period of post education would have decreased the effect of the restraint educational program (β: 0.08, p = 0.002); instead, the longer education period and more times of education would have a stronger effect of reducing the use of physical restraint (β: -0.07, p < 0.001; β: -0.04, p = 0.056). The educational program had an effect on the reduced use of physical restraint. The results of meta-regression suggest that long-term care facilities should provide a continuous education program of physical restraint for caregivers. Copyright © 2017.

For years ophthalmic photographs have been used to track the progression of many ocular diseases such as macular degeneration and glaucoma as well as the ocular manifestations of diabetes, hypertension, and hypoxia. In 1987 a project was initiated at the Johnson Space Center (JSC) to develop a means of monitoring retinal vascular caliber and intracranial pressure during space flight. To conduct telemedicine during space flight operations, retinal images would require real-time transmissions from space. Film-based images would not be useful during in-flight operations. Video technology is beneficial in flight because the images may be acquired, recorded, and transmitted to the ground for rapid computer digital image processing and analysis. The computer analysis techniques developed for this project detected vessel caliber changes as small as 3 percent. In the field of telemedicine, the Portable Dynamic Fundus Instrument demonstrates the concept and utility of a small, self-contained video funduscope. It was used to record retinal images during the Gulf War and to transmit retinal images from the Space Shuttle Columbia during STS-50. There are plans to utilize this device to provide a mobile ophthalmic screening service in rural Texas. In the fall of 1993 a medical team in Boulder, Colorado, will transmit real-time images of the retina during remote consultation and diagnosis. The research applications of this device include the capability of operating in remote locations or small, confined test areas. There has been interest shown utilizing retinal imaging during high-G centrifuge tests, high-altitude chamber tests, and aircraft flight tests. A new design plan has been developed to incorporate the video instrumentation into face-mounted goggle. This design would eliminate head restraint devices, thus allowing full maneuverability to the subjects. Further development of software programs will broaden the application of the Portable Dynamic Fundus Instrument in

Mixed selection. Effects of body images, dietary restraint, and persuasive messages on females' orientations towards chocolate.

Durkin, Kevin; Hendry, Alana; Stritzke, Werner G K

Many women experience ambivalent reactions to chocolate: craving it but also wary of its impact on weight and health. Chocolate advertisements often use thin ideal models and previous research indicates that this exacerbates ambivalence. This experiment compared attitudes to, and consumption of, chocolate following exposure to images containing thin or overweight models together with written messages that were either positive or negative about eating chocolate. Participants (all female) were categorised as either low- or high-restraint. Approach, avoidance and guilt motives towards chocolate were measured and the participants had an opportunity to consume chocolate. Exposure to thin ideal models led to higher approach motives and this effect was most marked among the high restraint participants. Avoidance and guilt scores did not vary as a function of model size or message, but there were clear differences between the restraint groups, with the high restraint participants scoring substantially higher than low restraint participants on both of these measures. When the participants were provided with an opportunity to eat some chocolate, those with high restraint who had been exposed to the thin models consumed the most. Copyright © 2012 Elsevier Ltd.

Maximum-likelihood X-ray macromolecular structure refinement in BUSTER has been extended with restraints facilitating the exploitation of structural similarity. The similarity can be between two or more chains within the structure being refined, thus favouring NCS, or to a distinct ‘target’ structure that remains fixed during refinement. The local structural similarity restraints (LSSR) approach considers all distances less than 5.5 Å between pairs of atoms in the chain to be restrained. For each, the difference from the distance between the corresponding atoms in the related chain is found. LSSR applies a restraint penalty on each difference. A functional form that reaches a plateau for large differences is used to avoid the restraints distorting parts of the structure that are not similar. Because LSSR are local, there is no need to separate out domains. Some restraint pruning is still necessary, but this has been automated. LSSR have been available to academic users of BUSTER since 2009 with the easy-to-use -autoncs and -­target target.pdb options. The use of LSSR is illustrated in the re-refinement of PDB entries 5rnt, where -target enables the correct ligand-binding structure to be found, and 1osg, where -autoncs contributes to the location of an additional copy of the cyclic peptide ligand.

Ledoux, William R; Rohr, Eric S; Ching, Randal P; Sangeorzan, Bruce J

2006-12-01

To eliminate some of the ambiguity in describing foot shape, we developed three-dimensional (3D), objective measures of foot type based on computerized tomography (CT) scans. Feet were classified via clinical examination as pes cavus (high arch), neutrally aligned (normal arch), asymptomatic pes planus (flat arch with no pain), or symptomatic pes planus (flat arch with pain). We enrolled 10 subjects of each foot type; if both feet were of the same foot type, then each foot was scanned (n=65 total). Partial weightbearing (20% body weight) CT scans were performed. We generated embedded coordinate systems for each foot bone by assuming uniform density and calculating the inertial matrix. Cardan angles were used to describe five bone-to-bone relationships, resulting in 15 angular measurements. Significant differences were found among foot types for 12 of the angles. The angles were also used to develop a classification tree analysis, which determined the correct foot type for 64 of the 65 feet. Our measure provides insight into how foot bone architecture differs between foot types. The classification tree analysis demonstrated that objective measures can be used to discriminate between feet with high, normal, and low arches. Copyright (c) 2006 Orthopaedic Research Society.

Effects of ankle-foot orthoses on mediolateral foot-placement ability during post-stroke gait.

PubMed

Zissimopoulos, Angelika; Fatone, Stefania; Gard, Steven

2015-10-01

Accurate and precise mediolateral foot placement is important for balance during gait, but is impaired post stroke. Mediolateral foot placement may be improved with ankle-foot orthosis use. The purpose of this study was to determine whether an ankle-foot orthosis improves mediolateral foot-placement ability during post-stroke ambulation. Crossover trial with randomized order of conditions tested. The accuracy and precision of mediolateral foot placement was quantified while subjects targeted four different randomized step widths. Subjects were tested with and without their regular non-rigid ankle-foot orthosis in two separate visits (order randomized). While ankle-foot orthosis use corrected foot and ankle alignment (i.e. significantly decreased mid-swing plantar flexion, p = 0.000), effects of ankle-foot orthosis use on hip hiking (p = 0.545), circumduction (p = 0.179), coronal plane hip range of motion (p = 0.06), and mediolateral foot-placement ability (p = 0.537) were not significant. While ankle-foot orthosis-mediated equinovarus correction of the affected foot and ankle was not associated with improved biomechanics of walking (i.e. proximal ipsilateral hip kinematics or mediolateral foot-placement ability), it may affect other aspects of balance that were not tested in this study (e.g. proprioception, cerebellar, vestibular, and cognitive mechanisms). Studies that investigate the effect of ankle-foot orthosis on gait can help advance stroke rehabilitation by documenting the specific gait benefits of ankle-foot orthosis use. In this study, we investigated the effect of ankle-foot orthosis use on mediolateral foot-placement ability, an aspect of gait important for maintaining balance. © The International Society for Prosthetics and Orthotics 2014.

The foot core system: a new paradigm for understanding intrinsic foot muscle function.

PubMed

McKeon, Patrick O; Hertel, Jay; Bramble, Dennis; Davis, Irene

2015-03-01

The foot is a complex structure with many articulations and multiple degrees of freedom that play an important role in static posture and dynamic activities. The evolutionary development of the arch of the foot was coincident with the greater demands placed on the foot as humans began to run. The movement and stability of the arch is controlled by intrinsic and extrinsic muscles. However, the intrinsic muscles are largely ignored by clinicians and researchers. As such, these muscles are seldom addressed in rehabilitation programmes. Interventions for foot-related problems are more often directed at externally supporting the foot rather than training these muscles to function as they are designed. In this paper, we propose a novel paradigm for understanding the function of the foot. We begin with an overview of the evolution of the human foot with a focus on the development of the arch. This is followed by a description of the foot intrinsic muscles and their relationship to the extrinsic muscles. We draw the parallels between the small muscles of the trunk region that make up the lumbopelvic core and the intrinsic foot muscles, introducing the concept of the foot core. We then integrate the concept of the foot core into the assessment and treatment of the foot. Finally, we call for an increased awareness of the importance of the foot core stability to normal foot and lower extremity function. Published by the BMJ Publishing Group Limited.

Foot roll-over is commonly analyzed to evaluate gait pathologies. The current study utilized a dynamic foot scanner (DFS) to analyze foot roll-over. The right feet of ten healthy subjects were assessed during gait trials with a DFS system integrated into a walkway. A foot sole picture was computed by vertically projecting points from the 3D foot shape which were lower than a threshold height of 15 mm. A 'height' value of these projected points was determined; corresponding to the initial vertical coordinates prior to projection. Similar to pedobarographic analysis, the foot sole picture was segmented into anatomical regions of interest (ROIs) to process mean height (average of height data by ROI) and projected surface (area of the projected foot sole by ROI). Results showed that these variables evolved differently to plantar pressure data previously reported in the literature, mainly due to the specificity of each physical quantity (millimeters vs Pascals). Compared to plantar pressure data arising from surface contact by the foot, the current method takes into account the whole plantar aspect of the foot, including the parts that do not make contact with the support surface. The current approach using height data could contribute to a better understanding of specific aspects of foot motion during walking, such as plantar arch height and the windlass mechanism. Results of this study show the underlying method is reliable. Further investigation is required to validate the DFS measurements within a clinical context, prior to implementation into clinical practice. Copyright © 2013 Elsevier B.V. All rights reserved.

To analyse the results of removing physical restraints from elderly patients with dementia living in nursing homes. This objective is part of a wider process of change in residential care. Quasi-experimental study conducted in two residences from May 2010 to May 2012. Information was collected at 7 time points and longitudinal analyses were performed. After training staff, the physical restraints in El Puig centre were phased out, while in the Conarda centre, restraints were still applied to elderly people. The main variables studied were: falls, psychotropic medication prescriptions, different indicators of mental impairment, and degree of dependence (Norton, NPI, Mini-mental, Tinetti, Barthel). In the El Puig centre all the physical restraints were removed. A slight improvement was seen in the number of falls, and their consequences. The ANOVA showed significant improvements in the centre that removed restraints in prescribing psychotropic medications, cognitive impairment, and behavioural changes. It is shown that removing physical restraints do not cause negative effects as regards the number of falls, and also positively affects the welfare and independence of elderly people (through changes in behaviour and mental impairment). Furthermore, it is demonstrated that this program must be accompanied by the reduction and control of medicines (withdrawal of the number of psychotropic prescriptions). Copyright © 2014 SEGG.

Angin, Salih; Mickle, Karen J; Nester, Christopher J

2018-03-01

The plantar foot muscles and plantar fascia differ between different foot postures. However, how each individual plantar structure contribute to foot posture has not been explored. The purpose of this study was to investigate the associations between static foot posture and morphology of plantar foot muscles and plantar fascia and thus the contributions of these structures to static foot posture. A total of 111 participants were recruited, 43 were classified as having pes planus and 68 as having normal foot posture using Foot Posture Index assessment tool. Images from the flexor digitorum longus (FDL), flexor hallucis longus (FHL), peroneus longus and brevis (PER), flexor hallucis brevis (FHB), flexor digitorum brevis (FDB) and abductor hallucis (AbH) muscles, and the calcaneal (PF1), middle (PF2) and metatarsal (PF3) regions of the plantar fascia were obtained using a Venue 40 ultrasound system with a 5-13 MHz transducer. In order of decreasing contribution, PF3 > FHB > FHL > PER > FDB were all associated with FPI and able to explain 69% of the change in FPI scores. PF3 was the highest contributor explaining 52% of increases in FPI score. Decreased thickness was associated with increased FPI score. Smaller cross sectional area (CSA) in FHB and PER muscles explained 20% and 8% of increase in FPI score. Larger CSA of FDB and FHL muscles explained 4% and 14% increase in FPI score respectively. The medial plantar structures and the plantar fascia appear to be the major contributors to static foot posture. Elucidating the individual contribution of multiple muscles of the foot could provide insight about their role in the foot posture. Copyright © 2018. Published by Elsevier B.V.

SUMMARY Objectives This study compares inter- and intra-country differences in the prevalence of physical restraints and antipsychotic medications in nursing homes, and examines aggregated resident conditions and organizational characteristics correlated with these treatments. Methods Population-based, cross-sectional data were collected using a standardized Resident Assessment Instrument (RAI) from 14,504 long-term care facilities providing nursing home level services in five countries participating in the interRAI consortium, including Canada, Finland, Hong Kong (Special Administrative Region, China), Switzerland, and the United States. Facility-level prevalence rates of physical restraints and antipsychotic use were examined both between and within the study countries. Results The prevalence of physical restraint use varied more than five-fold across the study countries, from an average 6% in Switzerland, 9% in the US, 20% in Hong Kong, 28% in Finland, and over 31% in Canada. The prevalence of antipsychotic use ranged from 11% in Hong Kong, between 26–27% in Canada and the US, 34% in Switzerland, and nearly 38% in Finland. Within each country, substantial variations existed across facilities in both physical restraint and antipsychotic use rates. In all countries, neither facility case mix nor organizational characteristics were particularly predictive of the prevalence of either treatment. Conclusions There exists large, unexplained variability in the prevalence of physical restraint and antipsychotic use in nursing home facilities both between and within countries. Since restraints and antipsychotics are associated with adverse outcomes, it is important to understand the idiosyncratic factors specific to each country that contribute to variation in use rates.

Motor rehabilitation using brain-computer interface (BCI) systems may facilitate functional recovery in individuals after stroke or spinal cord injury. Nevertheless, these systems are typically ill-suited for widespread adoption due to their size, cost, and complexity. In this paper, a small, portable, and extremely cost-efficient (<;$200) BCI system has been developed using a custom electroencephalographic (EEG) amplifier array, and a commercial microcontroller and touchscreen. The system's performance was tested using a movement-related BCI task in 3 able-bodied subjects with minimal previous BCI experience. Specifically, subjects were instructed to alternate between relaxing and dorsiflexing their right foot, while their EEG was acquired and analyzed in real-time by the BCI system to decode their underlying movement state. The EEG signals acquired by the custom amplifier array were similar to those acquired by a commercial amplifier (maximum correlation coefficient ρ=0.85). During real-time BCI operation, the average correlation between instructional cues and decoded BCI states across all subjects (ρ=0.70) was comparable to that of full-size BCI systems. Small, portable, and inexpensive BCI systems such as the one reported here may promote a widespread adoption of BCI-based movement rehabilitation devices in stroke and spinal cord injury populations.

Foot shape and size are important for footwear design and production. Information about important foot characteristics helps not only to improve shoe comfort but to maintain the proper physiological development of the feet. What's more, plenty of studies have suggested that the shape of the shoe must closely resemble the shape of the foot to create a properly fitted shoe. This means that the differences between various populations should be considered and that footwear should be designed according to the measurements of users. Childhood and adolescent are important periods of human growth. During these periods, foot shape changes with human growth and can be influenced by extrinsic factors. Therefore, the foot shape characteristics of children and adolescents should be investigated. The results from these investigations can contribute to developing appropriate shoe for children and adolescents, improving perceived comfort of children shoes and preventing pedopathy among children and adolescents. This review aims to discuss measuring methods of foot shape, types of foot shape, and factors influencing foot shape. The results of the review can provide recommendations for investigating growth development of foot shape and useful information for consumers and shoe manufacturers.

Restraint stress alters neutrophil and macrophage phenotypes during wound healing

Previous studies reported that stress delays wound healing, impairs bacterial clearance, and elevates the risk for opportunistic infection. Neutrophils and macrophages are responsible for the removal of bacteria present at the wound site. The appropriate recruitment and functions of these cells are necessary for efficient bacterial clearance. In our current study we found that restraint stress induced an excessive recruitment of neutrophils extending the inflammatory phase of healing, and the gene expression of neutrophil attracting chemokines MIP-2 and KC. However, restraint stress did not affect macrophage infiltration. Stress decreased the phagocytic abilities of phagocytic cells ex vivo, yet it did not affect superoxide production. The cell surface expression of adhesion molecules CD11b and TLR4 were decreased in peripheral blood monocytes in stressed mice. The phenotype of macrophages present at the wound site was also altered. Gene expression of markers of pro-inflammatory classically activated macrophages, CXCL10 and CCL5, were down-regulated; as were markers associated with wound healing macrophages, CCL22, IGF-1, RELMα; and the regulatory macrophage marker, chemokine CCL1. Restraint stress also induced up-regulation of IL10 gene expression. In summary, our study has shown that restraint stress suppresses the phenotype shift of the macrophage population, as compared to the changes observed during normal wound healing, while the number of macrophages remains constant. We also observed a general suppression of chemokine gene expression. Modulation of the macrophage phenotype could provide a new therapeutic approach in the treatment of wounds under stress conditions in the clinical setting. PMID:22884902

2010-01-01

Introduction The leading cause of injury and death among children in the United States is motor vehicle crashes. Even though restraint laws are in place and public awareness campaigns and educational interventions have increased, many children are still improperly restrained or not restrained at all. When correctly used, child restraints significantly reduce risk of injury or death. Methods The purpose of the study was to elicit caregiver baseline knowledge of car seat installation and regulation before receiving car seat education from certified technicians at Inspection Station events. Inspection Station is a program whereby staff assists parents in correctly positioning car seats in participants’ vehicles. Over an 8-week period, Safe Kids Cobb County Car Seat Technicians distributed a 16-item survey, with 10 knowledge-based questions and six demographic questions to Inspection Station participants. Descriptive statistics and t-tests were conducted to assess relationships between participant age, ethnicity, and gender with overall knowledge scores. Regression analysis was run to determine the association between participant education level and total child restraint knowledge. Results One hundred sixty-nine surveys were completed. Participant knowledge of vehicular child restraint ranged from 0% to 90% on all items. Only 29.6% of caregivers understood the proper tightness of the harness system. Less than half of the caregivers (43.8%) were aware of the Georgia law requiring children aged 6 years and younger to be in some type of child restraint. Only 43.2% of caregivers surveyed knew that children need to ride in a rear-facing child restraint until 1 year of age and 20 pounds. No significant correlations between participant knowledge and age were found. Statistically significant associations were found between total knowledge scores and education level, ethnicity, and gender. Discussion The results from this study describe baseline knowledge among a sample of

Cellular resolution functional imaging in behaving rats using voluntary head restraint

2013-01-01

SUMMARY High-throughput operant conditioning systems for rodents provide efficient training on sophisticated behavioral tasks. Combining these systems with technologies for cellular resolution functional imaging would provide a powerful approach to study neural dynamics during behavior. Here we describe an integrated two-photon microscope and behavioral apparatus that allows cellular resolution functional imaging of cortical regions during epochs of voluntary head restraint. Rats were trained to initiate periods of restraint up to 8 seconds in duration, which provided the mechanical stability necessary for in vivo imaging while allowing free movement between behavioral trials. A mechanical registration system repositioned the head to within a few microns, allowing the same neuronal populations to be imaged on each trial. In proof-of-principle experiments, calcium dependent fluorescence transients were recorded from GCaMP-labeled cortical neurons. In contrast to previous methods for head restraint, this system can also be incorporated into high-throughput operant conditioning systems. PMID:24055015

Cicchino, Jessica B; Jermakian, Jessica S

2015-06-01

The objective of this study was to determine if vehicle features associated with LATCH ease-of-use in laboratory studies with volunteers predict LATCH use and misuse in real-world child restraint installations. Vehicle characteristics were extracted from prior surveys of more than 100 top-selling 2010-13 vehicles. Use and correct use of LATCH was determined from records of more than 14,000 child restraint installations in these vehicles that were inspected by child passenger safety technicians at Safe Kids car seat checkup events during 2010-12. Logistic regression was used to examine the association between vehicle features and use and correct use of lower anchors and top tethers, controlling for other relevant installation features. Lower anchors were more likely to be used and correctly used when the clearance angle around them was greater than 54°, the force required to attach them to the lower anchors was less than 178N, and their depth within the seat bight was less than 4cm. Restraints were more likely to be attached correctly when installed with the lower anchors than with the seat belt. After controlling for lower anchor use and other installation features, the likelihood of tether use and correct use in installations of forward-facing restraints was significantly higher when there was no hardware present that could potentially be confused with the tether anchor or when the tether anchor was located on the rear deck, which is typical in sedans. There is converging evidence from laboratory studies with volunteers and real-world child restraint installations that vehicle features are associated with correct LATCH use. Vehicle designs that improve the ease of installing child restraints with LATCH could improve LATCH use rates and reduce child restraint misuse.

Effects and costs of requiring child-restraint systems for young children traveling on commercial airplanes.

PubMed

Newman, Thomas B; Johnston, Brian D; Grossman, David C

2003-10-01

The US Federal Aviation Administration is planning a new regulation requiring children younger than 2 years to ride in approved child-restraint seats on airplanes. To estimate the annual number of child air crash deaths that might be prevented by the proposed regulation, the threshold proportion of families switching from air to car travel above which the risks of the policy would exceed its benefits, and the cost per death prevented. Risk and economic analyses. Child-restraint seat use could prevent about 0.4 child air crash deaths per year in the United States. Increased deaths as a result of car travel could exceed deaths prevented by restraint seat use if the proportion of families switching from air to car travel exceeded about 5% to 10%. The estimate for this proportion varied with assumptions about trip distance, driver characteristics, and the effectiveness of child-restraint seats but is unlikely to exceed 15%. Assuming no increase in car travel, for each dollar increase in the cost of implementing the regulation per round trip per family, the cost per death prevented would increase by about $6.4 million. Unless space for young children in restraint seats can be provided at low cost to families, with little or no diversion to automobile travel, a policy requiring restraint seat use could cause a net increase in deaths. Even excluding this possibility, the cost of the proposed policy per death prevented is high.

Success importance and urge magnitude as determinants of cardiovascular response to a behavioral restraint challenge.

2016-04-01

Decades of research have investigated a conceptual analysis concerned with determinants and cardiovascular correlates of effort in people confronted with performance challenges, that is, opportunities to alter some course of events by acting. One suggestion is that effort and associated cardiovascular responses should be determined jointly by the difficulty of meeting a challenge and the importance of doing so. The present experiment tested this in a context involving behavioral restraint, that is, effortful resistance against a behavioral impulse or urge. Participants were presented a mildly evocative violent film clip (restraint difficulty low) or a strongly evocative violent film clip (restraint difficulty high) with instructions to refrain from showing any facial response. Success was made more or less important through coordinated manipulations of outcome expectancy, ego-involvement and social evaluation. As expected, SBP responses assessed during the work period were proportional to clip evocativeness - i.e., the difficulty of the restraint challenge - when importance was high, but low regardless of clip evocativeness when importance was low. Findings conceptually replicate previous cardiovascular results and support extension of the guiding analysis to the behavioral restraint realm. Copyright © 2016 Elsevier B.V. All rights reserved.

Nurses are more likely to face the dilemma of whether to resort to physical restraints or not and have a hard time making that decision. This is a descriptive study. A total of 55 nurses participated in the research. For data collection, a question form developed by researchers to determine perceptions of ethical dilemmas by nurses in the application of physical restraint was used. A descriptive analysis was made by calculating the mean, standard deviation, and maximum and minimum values. The nurses expressed (36.4%) having difficulty in deciding to use physical restraint. Nurses reported that they experience ethical dilemmas mainly in relation to the ethic principles of nonmaleficence, beneficence, and convenience. We have concluded that majority of nurses working in critical care units apply physical restraint to patients, although they are facing ethical dilemmas concerning harm and benefit principles during the application.

Effect of using poles on foot-ground kinetics during stance phase in trail running.

Daviaux, Yannick; Hintzy, Frédérique; Samozino, Pierre; Horvais, Nicolas

2013-01-01

The aim of this study was to investigate the effect of using poles on foot-ground interaction during trail running with slopes of varying incline. Ten runners ran on a loop track representative of a trail running field situation with uphill (+9°), level and downhill (-6°) sections at fixed speed (3.2 m.s(-1)). Experimental conditions included running with (WP) and without (NP) the use of poles for each of the three slopes. Several quantitative and temporal foot-ground interaction parameters were calculated from plantar pressure data measured with a portable device. Using poles induced a decrease in plantar pressure intensity even when the running velocity stayed constant. However, the localisation and the magnitude of this decrease depended on the slope situations. During WP level running, regional analysis of the foot highlighted a decrease of the force time integral (FTI) for absolute (FTIabs; -12.6%; P<0.05) and relative values (FTIrel; -14.3%; P<0.05) in the medial forefoot region. FTIabs (-14.2%; P<0.05) and duration of force application (Δt; -13.5%; P<0.05) also decreased in the medial heel region when WP downhill running. These results support a facilitating effect of pole use for propulsion during level running and for the absorption phase during downhill running.

Nursing staff members' intentions to use physical restraints with older people: testing the theory of reasoned action.

PubMed

Werner, P; Mendelsson, G

2001-09-01

To examine nursing staff members' attitudes, subjective norms, moral obligations and intentions to use physical restraints, using the Theory of Reasoned Action (TRA). During the last two decades an extensive body of research has examined nurses' attitudes as one of the main factors affecting the decision to use or not to use physical restraints with older persons. However, no studies have examined empirically the antecedents to nurses' intentions to use physical restraints within a theoretically based framework. A correlational design was used with 303 nursing staff members from an 800-bed elder care hospital in central Israel. Participants completed a questionnaire including questions based on the TRA as well as socio-demographic and professional characteristics. Regression analyses found attitudes, subjective norms and moral considerations to be significantly associated to intention to use physical restraints with older people. The TRA explained 48% of the variance in nurses' intentions. The TRA proved to be a useful framework for examining nurses' intentions to use physical restraints. Nurses' attitudes, beliefs and expectations of significant others should be examined before implementing educational programmes regarding the use of physical restraints.

Prospectively Predicting Dietary Restraint: The Role of Interpersonal Self-Efficacy, Weight/Shape Self-Efficacy, and Interpersonal Stress

Cain, A.S.; Bardone-Cone, A.M.; Abramson, L.Y.; Vohs, K.D.; Joiner, T.E.

2009-01-01

Objective This study investigated how the precursors of interpersonal self-efficacy and weight/shape self-efficacy would interact in the face of interpersonal stress to prospectively predict dietary restraint. Three models were explored, each with a different type of interpersonal stress: stress from same sex friendships, opposite sex friendships, or romantic relationships. Method At Time 1 (T1), participants (N = 406) reported on their typical levels of interpersonal self-efficacy and weight/shape self-efficacy, and recent (past 28 days) dietary restraint. At Time 2 (T2), 11 weeks after T1, participants reported on their recent (past 28 days) levels of dietary restraint at that time. Between T1 and T2, participants completed inventories weekly on the previous week’s interpersonal stressors. Results Consistent with prediction, low interpersonal self-efficacy and high weight/shape self-efficacy combined with high interpersonal stress (whether from same sex friendships, opposite sex friendships, or romantic relationships) to predict the highest levels of T2 dietary restraint after controlling for T1 levels. Conclusion These results further link the interpersonal domain with dietary restraint and elucidate characteristics of women particularly apt to increase dietary restraint in response to interpersonal stress.

Crosslinking Mass Spectrometry generates restraints that can be used to model proteins and protein complexes. Previously, we have developed two methods, to help users achieve better modelling performance from their crosslinking restraints: Jwalk, to estimate solvent accessible distances between crosslinked residues and MNXL, to assess the quality of the models based on these distances. Here we present the Jwalk and MNXL webservers, which streamline the process of validating monomeric protein models using restraints from crosslinks. We demonstrate this by using the MNXL server to filter models made of varying quality, selecting the most native-like. The webserver and source code are freely available from jwalk.ismb.lon.ac.uk and mnxl.ismb.lon.ac.uk. m.topf@cryst.bbk.ac.uk, j.bullock@cryst.bbk.ac.uk.

2016-01-01

Orthopedic insole was important for partial foot amputation (PFA) to achieve foot balance and avoid foot deformity. The inapposite insole orthosis was thought to be one of the risk factors of reamputation for foot valgus patient, but biomechanical effects of internal tissues on valgus foot had not been clearly addressed. In this study, plantar pressure on heel and metatarsal regions of PFA was measured using F-Scan. The three-dimensional finite element (FE) model of partial foot evaluated different medial wedge angles (MWAs) (0.0°-10.0°) of orthopedic insole on valgus foot. The effect of orthopedic insole on the internal bone stress, the medial ligament tension of ankle, plantar fascia tension, and plantar pressure was investigated. Plantar pressure on medial heel region was about 2.5 times higher than that of lateral region based on the F-Scan measurements. FE-predicted results showed that the tension of medial ankle ligaments was the lowest, and the plantar pressure was redistributed around the heel, the first metatarsal, and the lateral longitudinal arch regions when MWA of orthopedic insole ranged from 7.5° to 8.0°. The plantar fascias maintained about 3.5% of the total load bearing on foot. However, the internal stresses from foot bones increased. The simulation in this study would provide the suggestion of guiding optimal design of orthopedic insole and therapeutic planning to pedorthist.

Is the foot elevation the optimal position for wound healing of a diabetic foot?

PubMed

Park, D J; Han, S K; Kim, W K

2010-03-01

In managing diabetic foot ulcers, foot elevation has generally been recommended to reduce oedema and prevent other sequential problems. However, foot elevation may decrease tissue oxygenation of the foot more than the dependent position since the dependent position is known to increase blood flow within the arterial system. In addition, diabetic foot ulcers, which have peripheral vascular insufficiency, generally have less oedema than other wounds. Therefore, we argue that foot elevation may not be helpful for healing of vascularly compromised diabetic foot ulcers since adequate tissue oxygenation is an essential factor in diabetic wound healing. The purpose of this study was to evaluate the influence of foot height on tissue oxygenation and to determine the optimal foot position to accelerate wound healing of diabetic foot ulcers. This study included 122 cases (73 males and 47 females; two males had bilateral disease) of diabetic foot ulcer patients aged 40-93 years. Trans-cutaneous partial oxygen tension (TcpO(2)) values of diabetic feet were measured before and after foot elevation (n=21). Elevation was achieved by placing a foot over four cushions. We also measured foot TcpO(2) values before and after lowering the feet (n=122). Feet were lowered to the patient's tibial height, approximately 30-35 cm, beside a bed handrail. Due to the large number of lowering measurements, we divided them into five sub-groups according to initial TcpO(2.) Tissue oxygenation values were compared. Foot-elevation-lowered TcpO(2) values before and after elevation were 32.5+/-22.2 and 23.8+/-23.1 mmHg (p<0.01), respectively. Foot-lowering-augmented TcpO(2) values before and after lowering were 44.6+/-23.8 and 58.0+/-25.9 mmHg (p<0.01), respectively. The lower the initial TcpO(2) level, the more the TcpO(2) level increased. The foot lowering, rather than elevation, significantly augments TcpO(2) and may stimulate healing of diabetic foot ulcers.

Effects of chronic restraint stress on body weight, food intake, and hypothalamic gene expressions in mice.

PubMed

Jeong, Joo Yeon; Lee, Dong Hoon; Kang, Sang Soo

2013-12-01

Stress affects body weight and food intake, but the underlying mechanisms are not well understood. We evaluated the changes in body weight and food intake of ICR male mice subjected to daily 2 hours restraint stress for 15 days. Hypothalamic gene expression profiling was analyzed by cDNA microarray. Daily body weight and food intake measurements revealed that both parameters decreased rapidly after initiating daily restraint stress. Body weights of stressed mice then remained significantly lower than the control body weights, even though food intake slowly recovered to 90% of the control intake at the end of the experiment. cDNA microarray analysis revealed that chronic restraint stress affects the expression of hypothalamic genes possibly related to body weight control. Since decreases of daily food intake and body weight were remarkable in days 1 to 4 of restraint, we examined the expression of food intake-related genes in the hypothalamus. During these periods, the expressions of ghrelin and pro-opiomelanocortin mRNA were significantly changed in mice undergoing restraint stress. Moreover, daily serum corticosterone levels gradually increased, while leptin levels significantly decreased. The present study demonstrates that restraint stress affects body weight and food intake by initially modifying canonical food intake-related genes and then later modifying other genes involved in energy metabolism. These genetic changes appear to be mediated, at least in part, by corticosterone.

2010-02-25

The use of physical restraints still is common practice in the nursing home care. Since physical restraints have been shown to be an ineffective and sometimes even hazardous measure, interventions are needed to reduce their usage. Several attempts have been made to reduce the use of physical restraints. Most studies used educational approaches and introduced a nurse specialist as a consultant. However, the success rate of these interventions has been inconsistent. We developed a new multi-component intervention (EXBELT) comprising an educational intervention for nursing home staff in combination with a policy change (belt use is prohibited by the nursing home management), availability of a nurse specialist and nursing home manager as consultants, and availability of alternative interventions. The first aim of this study is to further develop and test the effectiveness of EXBELT on belt restraint reduction in Dutch psychogeriatric nursing homes. However, the reduction of belts should not result in an increase of other restrictive restraints (such as a chair with locked tray table) or psychoactive drug use. The overall aim is an effective and feasible intervention that can be employed on a large scale in Dutch nursing homes. Effects of EXBELT will be studied in a quasi-experimental longitudinal study design. Alongside the effect evaluation, a process evaluation will be carried out in order to further develop EXBELT. Data regarding age, gender, use of physical restraints, the number of falls and fall related injuries, psychoactive drug use, and the use of alternative interventions will be collected at baseline and after four and eight months of follow-up. Data regarding the process evaluation will be gathered in a period of eight months between baseline and the last measurement. Furthermore, changing attitudes will become an important addition to the educational part of EXBELT. A quasi-experimental study is presented to investigate the effects of EXBELT on the use of

Outdoor dynamic subject-specific evaluation of internal stresses in the residual limb: hydraulic energy-stored prosthetic foot compared to conventional energy-stored prosthetic feet.

The prosthetic foot plays an important role in propelling, breaking, balancing and supporting body loads while the amputee ambulates on different grounds. It is therefore important to quantify the effect of the prosthetic foot mechanism on biomechanical parameters, in order to prevent pressure ulcers and deep tissue injury. Our aim was to monitor the internal stresses in the residuum of transtibial amputation (TTA) prosthetic-users ambulating on different terrains, which the amputees encounter during their daily activities, i.e. paved floor, grass, ascending and descending stairs and slope. We specifically aimed to compare between the internal stresses in the TTA residuum of amputees ambulating with a novel hydraulic prosthetic foot compared to conventional energy storage and return (ESR) prosthetic feet. Monitoring of internal stresses was accomplished using a portable subject-specific real-time internal stress monitor. We found significant decrease (p<0.01) in peak internal stresses and in the loading rate of the amputated limb, while walking with the hydraulic foot, compared to walking with ESR feet. The loading rate calculated while ambulating with the hydraulic foot was at least three times lower than the loading rate calculated while ambulating with the ESR foot. Although the average decrease in internal stresses was ≈ 2-fold larger when replacing single-toe ESR feet with the hydraulic foot than when replacing split-toed ESR feet with the hydraulic foot, the differences were statistically insignificant. Our findings suggest that using a hydraulic prosthetic foot may protect the distal tibial end of the TTA residuum from high stresses, therefore preventing pressure-related injury and pain.

Crew Restraint Design for the International Space Station

NASA Technical Reports Server (NTRS)

Norris, Lena; Holden, Kritina; Whitmore, Mihriban

2006-01-01

With permanent human presence onboard the International Space Station (ISS), crews will be living and working in microgravity, dealing with the challenges of a weightless environment. In addition, the confined nature of the spacecraft environment results in ergonomic challenges such as limited visibility and access to the activity areas, as well as prolonged periods of unnatural postures. Without optimum restraints, crewmembers may be handicapped for performing some of the on-orbit tasks. Currently, many of the tasks on ISS are performed with the crew restrained merely by hooking their arms or toes around handrails to steady themselves. This is adequate for some tasks, but not all. There have been some reports of discomfort/calluses on the top of the toes. In addition, this type of restraint is simply insufficient for tasks that require a large degree of stability. Glovebox design is a good example of a confined workstation concept requiring stability for successful use. They are widely used in industry, university, and government laboratories, as well as in the space environment, and are known to cause postural limitations and visual restrictions. Although there are numerous guidelines pertaining to ventilation, seals, and glove attachment, most of the data have been gathered in a 1-g environment, or are from studies that were conducted prior to the early 1980 s. Little is known about how best to restrain a crewmember using a glovebox in microgravity. Another ISS task that requires special consideration with respect to restraints is robotic teleoperation. The Robot Systems Technology Branch at the NASA Johnson Space Center is developing a humanoid robot astronaut, or Robonaut. It is being designed to perform extravehicular activities (EVAs) in the hazardous environment of space. An astronaut located inside the ISS will remotely operate Robonaut through a telepresence control system. Essentially, the robot mimics every move the operator makes. This requires the

The return of restraint in psychiatry raises many ethical issues for caregivers. However their experience is little explored in literature. Our objective was to study the feelings of caregivers facing restraint with regard to an ethical perspective and to identify areas for improvement. Between November 2011 and February 2012 a descriptive cross-sectional epidemiological study was performed in two psychiatric emergency services and two closed units in which doctors and nurses were individually interviewed using semi-structured questionnaires. Five topics were explored: indications and contexts, impact on the patient, caregiver-patient relationship, perspective on the practice and feelings of caregivers on which we insist particularly. Results were presented in tables with percentages and possibly diagrams. The notable responses of caregivers were also cited. Twenty nurses and nine psychiatrists, mostly female, were recruited. They all had participated in experiments of restraint. The self-aggressiveness, the aggressiveness against other persons and agitation were the most frequent indications. In the patients, caregivers identified misunderstanding (79.3%) and anger (75.9%). The majority of nurses (75%) felt that there was an improvement in the caregiver-patient relationship after the episode of restraint compared to what it had been in the moments preceding this measure. The emotional experience of caregivers was rich, intense and predominantly negative type of frustration (35% of nurses; 66.7% of doctors), anger (30 and 33.3%) and lack of feeling (35 and 44.4%). The feelings of doctors and nurses were not completely similar. For caregivers it was "a difficult but necessary experience" (82.75%), "an act of care and safety" (68.9%). All psychiatrists and almost half of the nurses (45%) said they did not feel the same when they used seclusion. In their opinion, seclusion entailed a less painful experience because of its therapeutic properties. More than half of the

The objective was to investigate the association of pregravid weight status, dietary restraint and psychosocial factors during pregnancy. We used data from the Pregnancy, Infection and Nutrition study, that recruited 2,006 women at prenatal clinics before 20 weeks’ gestation who were >16 years and English speaking. Institute of Medicine BMI cutpoints of underweight (<19.8), normal weight (19.8–26.0), overweight (>26.0–29.0), obese (>29.0–34.9) and an additional category morbidly obese (≥ 35.0), were used to categorize weight status. Eight psychosocial measures and dietary restraint were assessed with regard to BMI; perceived stress, trait anxiety, depression symptoms, and internal locus of control (LOC), chance LOC, powerful others LOC, self-esteem and mastery. Linear regression was used to estimate associations, controlling for potential confounders. A significant test for trend was found between increasing pregravid weight categories and perceived stress, trait anxiety, depression symptoms, powerful others LOC, self-esteem, mastery and dietary restraint. In adjusted models, pregravid obesity was independently associated with perceived stress, trait anxiety and depression. Morbidly obese status was independently associated with all measures except internal LOC. A strong linear association was found between increasing weight categories and dietary restraint. A consistent association was found between pregravid weight status, psychosocial factors and dietary restraint. If corroborated, these findings suggest that with increasing pregravid weight, pregnant women are at greater risk for experiencing negative psychological states, are less likely to experience positive personal dispositions, and may need additional support to prevent adverse maternal complications and pregnancy outcomes.

This study examined the importance of body image evaluation and investment to predict dietary restraint in men (N = 272). Measures of physical activity, evaluation, investment and dietary restraint were completed. A hierarchical regression was conducted to predict dietary restraint from physical activity and body mass index (entered on the first step), body image evaluation (entered on the second step) and investment (entered on the final step). The overall regression was significant, F(4, 271) = 15.12, p < .001, R (2) adj = .17). Body mass index, physical activity and body image investment were significant positive predictors of dietary restraint. The present findings emphasize measuring body image investment. © The Author(s) 2015.

This study explored psychiatric inpatients' experiences of, and their suggestions for, improvement of seclusion/restraint, and alternatives to their use in Finland. The data were collected by focused interviews (n= 30) and were analyzed with inductive content analysis. Patients' perspectives received insufficient attention during seclusion/restraint processes. Improvements (e.g., humane treatment) and alternatives (e.g., empathetic patient-staff interaction) to seclusion/restraint, as suggested by the patients, focused on essential parts of nursing practice but have not been largely adopted. Patients' basic needs have to be met, and patient-staff interaction has to also continue during seclusion/restraint. Providing patients with meaningful activities, planning beforehand, documenting the patients' wishes, and making patient-staff agreements reduce the need for restrictions and offer alternatives for seclusion/restraint. Service users must be involved in all practical development. © 2011 Wiley Periodicals, Inc.

Repeated Neck Restraint Stress Bidirectionally Modulates Excitatory Transmission in the Dentate Gyrus and Performance in a Hippocampus-dependent Memory Task.

PubMed

Spyrka, Jadwiga; Hess, Grzegorz

2018-05-21

The consequences of stress depend on characteristics of the stressor, including the duration of exposure, severity, and predictability. Exposure of mice to repeated neck restraint has been shown to bidirectionally modulate the potential for long-term potentiation (LTP) in the dentate gyrus (DG) in a manner dependent on the number of restraint repetitions, but the influence of repeated brief neck restraint on electrophysiology of single DG neurons has not yet been investigated. Here, we aimed at finding the effects of 1, 3, 7, 14, or 21 daily neck restraint sessions lasting 10 min on electrophysiological characteristics of DG granule cells as well as excitatory and inhibitory synaptic inputs to these neurons. While the excitability of DG granule cells and inhibitory synaptic transmission were unchanged, neck restraint decreased the frequency of spontaneous excitatory currents after three repetitions but enhanced it after 14 and 21 repetitions. The consequences of repeated neck restraint on hippocampus-dependent memory were investigated using the object location test (OLT). Neck restraint stress impaired cognitive performance in the OLT after three repetitions but improved it after 14 and 21 repetitions. Mice subjected to three neck restraint sessions displayed an increase in the measures of depressive and anxiety-like behaviors, however, prolongation of the exposure to neck restraint resulted in a gradual decline in the intensity of these measures. These data indicate that stress imposed by an increasing number of repeated neck restraint episodes bidirectionally modulates both excitatory synaptic transmission in the DG and cognitive performance in the object location memory task.

A prior study examined the policies of U.S. air carriers with regard to the use of infant restraint systems on board commercial aircraft. This study expands on that earlier study by examining the policies of commuter air carriers in the United States regarding the use of infant restraint systems. The management policy of the commuter air carriers has been investigated and officials of the commuter air carriers were surveyed to determine how the carriage of infants onboard their aircraft varied among commuter airlines. The topics investigated included seat space for infants, restraint systems for infants, and amenities for infant passengers. The results of this study have been analyzed to ascertain if any recommendations can be made to the commuter airlines regarding the carriage of infants onboard their aircraft.

Clinical training in managing conflicts and preventing violence seldom contains sensory modulation (SM) as a method to de-escalate and prevent restraint and seclusion. Sensory-based interventions promote adaptive regulation of arousal and emotion. SM is a complementary approach that is associated with reduced rates of seclusion and restraint in mental healthcare, but there is need for more research in this area. Using SM to reduce restraint and seclusion in inpatient mental health care. The study included two similar psychiatric units where one unit implemented SM and one unit served as the control group. In the very beginning of the study, a staff-training program in the use of SM including assessment tools and intervention strategies was established. Data on restraint and forced medicine were sampled post the course of the year of implementation and compared with the control group. The use of belts decreased with 38% compared to the control group. The use of forced medication decreased with 46% compared to the control group. Altogether the use of physical restraint and forced medication decreased significantly with 42% (p < .05). Implementing a SM approach in mental healthcare facilities has a significant effect on the reduction of restraint and seclusion. As a part of the implementation, staff training and education in SM are crucial.

[Effects of an educational program for the reduction of physical restraint use by caregivers in geriatric hospitals].

Choi, Keumbong; Kim, Jinsun

2009-12-01

The purposes of this study were to develop an educational program to reduce the use of physical restraints for caregivers in geriatric hospitals and to evaluate the effects of the program on caregivers' knowledge, attitude and nursing practice related to the use of physical restraints. A quasi experimental study with a non-equivalent control group pretest-posttest design was used. Participants were recruited from two geriatric hospitals. Eighteen caregivers were assigned to the experimental group and 20 to the control group. The data were collected prior to the intervention and at 6 weeks after the intervention through the use of self-administered questionnaires. Descriptive statistics, X(2) test, Fisher's exact probability test, and Mann-Whitney U test were used to analyze the data. After the intervention, knowledge about physical restraints increased significantly in experimental group compared to the control group. However, there were no statistically significant differences between the groups for attitude and nursing practice involving physical restraints. Findings indicate that it is necessary to apply knowledge acquired through educational programs to nursing practice to reduce the use of physical restraints. User friendly guidelines for physical restraints, administrative support of institutions, and multidisciplinary approaches are required to achieve this goal.

Combined Ankle-Foot Energetics are Conserved When Distal Foot Energy Absorption is Minimized.

PubMed

Arch, Elisa S; Fylstra, Bretta L

2016-12-01

The large, late-stance energy generated by the ankle is believed to be critical during gait. However, the distal foot absorbs/dissipates a considerable amount of energy during the same phase. Thus, the energy generated by the combined ankle-foot system is more modest, which raises questions regarding the necessity of such a large ankle power and the interplay between foot and ankle energetics. This study aimed to evaluate our conservation of energy hypothesis, which predicted if distal foot energy absorption/dissipation was reduced, then less energy would be generated at the ankle and thus the same combined ankle-foot energetics would be achieved. Motion analysis data were collected as healthy subjects walked under 2 conditions (Shoes, Footplate). In the Footplate condition, the shoe was replaced with a customized, rigid footplate with a rocker profile. In support of the hypothesis, there was significantly less positive ankle and less negative distal foot work with footplate use, resulting in very similar combined ankle-foot work between conditions. These findings suggest that there is an interplay between the energy generated by the ankle and absorbed by the foot. This interplay should be considered when designing orthotic and prosthetic ankle-foot systems and rehabilitation programs for individuals with weakened ankle muscles.

Library faculty participation on the School of Medicine Curriculum Steering Committee led to a unique opportunity to partner technology and teaching utilizing the library's portable wireless classroom. The pathology lab course master expressed a desire to revise the curriculum using patient cases and direct access to the Web and library resources. Since the pathology lab lacked computers, the library's portable wireless classroom provided a solution. Originally developed to provide maximum portability and flexibility, the wireless classroom consists of ten laptop computers configured with wireless cards and an access point. While the portable wireless classroom led to a partnership with the School of Medicine, there were additional benefits and positive consequences for the library.

Silymarin Prevents Restraint Stress-Induced Acute Liver Injury by Ameliorating Oxidative Stress and Reducing Inflammatory Response.

PubMed

Kim, Sou Hyun; Oh, Dal-Seok; Oh, Ji Youn; Son, Tae Gen; Yuk, Dong Yeon; Jung, Young-Suk

2016-04-01

Silymarin is a flavonoid extracted from the milk thistle Silybum marianum. It has been reported to prevent liver injuries induced by various chemicals or toxins. Our recent study suggested that silymarin induces hepatic synthesis of glutathione by increasing cysteine availability, which may consequently contribute to increased antioxidant capacity of the liver. In the present study, we investigated the effects of silymarin on acute liver injury induced by restraint stress. Silymarin (100 mg/kg) was orally administered to BALB/c mice every 12 h (3 times in total). After the last dose, mice were subjected to restraint stress for 6 h, and serum levels of aspartate and alanine aminotransferases, and hepatic levels of lipid peroxidation were determined. Hepatic levels of sulfur-containing metabolites such as methionine, S-adenosylmethionine, cysteine, and glutathione were also measured. The level of pro-inflammatory mediators in both liver and serum was determined. To study the mechanism of the effects of silymarin, we assessed Jun N-terminal kinase (JNK) activation and apoptotic signaling. Restraint stress induced severe oxidative stress and increased mRNA levels of pro-inflammatory mediators; both effects of restraint stress were significantly inhibited by silymarin. Moreover, administration of silymarin significantly prevented acute liver injury induced by restraint stress by blocking JNK activation and subsequently apoptotic signaling. In conclusion, these results suggest that the inhibition of restraint stress-induced liver injury by silymarin is due at least in part to its anti-oxidant activity and its ability to suppress the inflammatory response.

Trunk restraint to promote upper extremity recovery in stroke patients: a systematic review and meta-analysis.

PubMed

Wee, Seng Kwee; Hughes, Ann-Marie; Warner, Martin; Burridge, Jane H

2014-09-01

Many stroke patients exhibit excessive compensatory trunk movements during reaching. Compensatory movement behaviors may improve upper extremity function in the short-term but be detrimental to long-term recovery. To evaluate the evidence that trunk restraint limits compensatory trunk movement and/or promotes better upper extremity recovery in stroke patients. A search was conducted through electronic databases from January 1980 to June 2013. Only randomized controlled trials (RCTs) comparing upper extremity training with and without trunk restraint were selected for review. Three review authors independently assessed the methodological quality and extracted data from the studies. Meta-analysis was conducted when there was sufficient homogenous data. Six RCTs involving 187 chronic stroke patients were identified. Meta-analysis of key outcome measures showed that trunk restraint has a moderate statistically significant effect on improving Fugl-Meyer Upper Extremity (FMA-UE) score, active shoulder flexion, and reduction in trunk displacement during reaching. There was a small, nonsignificant effect of trunk restraint on upper extremity function. Trunk restraint has a moderate effect on reduction of upper extremity impairment in chronic stroke patients, in terms of FMA-UE score, increased shoulder flexion, and reduction in excessive trunk movement during reaching. There is insufficient evidence to demonstrate that trunk restraint improves upper extremity function and reaching trajectory smoothness and straightness in chronic stroke patients. Future research on stroke patients at different phases of recovery and with different levels of upper extremity impairment is recommended. © The Author(s) 2014.

Coercive Restraint Therapies: A Dangerous Alternative Mental Health Intervention

PubMed Central

Mercer, Jean

2005-01-01

Abstract and Introduction Abstract Physicians caring for adopted or foster children should be aware of the use of coercive restraint therapy (CRT) practices by parents and mental health practitioners. CRT is defined as a mental health intervention involving physical restraint and is used in adoptive or foster families with the intention of increasing emotional attachment to parents. Coercive restraint therapy parenting (CRTP) is a set of child care practices adjuvant to CRT. CRT and CRTP have been associated with child deaths and poor growth. Examination of the CRT literature shows a conflict with accepted practice, an unusual theoretic basis, and an absence of empirical support. Nevertheless, CRT appears to be increasing in popularity. This article discusses possible reasons for the increase, and offers suggestions for professional responses to the CRT problem. Introduction The term coercive restraint therapy (CRT) describes a category of alternative mental health interventions that are generally directed at adopted or foster children, that are claimed to cause alterations in emotional attachment, and that employ physically intrusive techniques. Other names for such treatments are attachment therapy, corrective attachment therapy, dyadic synchronous bonding, holding therapy, rage reduction therapy, and Z-therapy. CRT may be carried out by practitioners trained in extracurricular workshops, or such practitioners may instruct parents who perform all or part of the treatment. CRT practices involve the use of restraint as a tool of treatment rather than simply as a safety device. While restraining the child, CRT practitioners may also exert physical pressure in the form of tickling or intense prodding of the torso, grab the child's face, and command the child to kick the legs rhythmically. Some CRT practitioners lie prone with their body weight on the child, a practice they call compression therapy. Most practitioners restrain the child in a supine position, but some

2015-02-01

Deflectometry is a powerful metrology technique that uses off-the-shelf equipment to achieve nanometer-level accuracy surface measurements. However, there is no portable device to quickly measure eyeglasses, lenses, or mirrors. We present an entirely portable new deflectometry technique that runs on any Android™ smartphone with a front-facing camera. Our technique overcomes some specific issues of portable devices like screen nonlinearity and automatic gain control. We demonstrate our application by measuring an amateur telescope mirror and simulating a measurement of the faulty Hubble Space Telescope primary mirror. Our technique can, in less than 1 min, measure surface errors with accuracy up to 50 nm RMS, simply using a smartphone.

2017-10-01

Today, due to technology development and aversive events of daily life, Human exposure to both radiofrequency and stress is unavoidable. This study investigated the co-exposure to repeated restraint stress and WiFi signal on cognitive function and oxidative stress in brain of male rats. Animals were divided into four groups: Control, WiFi-exposed, restrained and both WiFi-exposed and restrained groups. Each of WiFi exposure and restraint stress occurred 2 h (h)/day during 20 days. Subsequently, various tests were carried out for each group, such as anxiety in elevated plus maze, spatial learning abilities in the water maze, cerebral oxidative stress response and cholinesterase activity in brain and serum. Results showed that WiFi exposure and restraint stress, alone and especially if combined, induced an anxiety-like behavior without impairing spatial learning and memory abilities in rats. At cerebral level, we found an oxidative stress response triggered by WiFi and restraint, per se and especially when combined as well as WiFi-induced increase in acetylcholinesterase activity. Our results reveal that there is an impact of WiFi signal and restraint stress on the brain and cognitive processes especially in elevated plus maze task. In contrast, there are no synergistic effects between WiFi signal and restraint stress on the brain.

Pérez, Miguel Ángel; Pérez-Valenzuela, Catherine; Rojas-Thomas, Felipe; Ahumada, Juan; Fuenzalida, Marco; Dagnino-Subiabre, Alexies

2013-08-29

Chronic stress induces dendritic atrophy in the rat primary auditory cortex (A1), a key brain area for auditory attention. The aim of this study was to determine whether repeated restraint stress affects auditory attention and synaptic transmission in A1. Male Sprague-Dawley rats were trained in a two-alternative choice task (2-ACT), a behavioral paradigm to study auditory attention in rats. Trained animals that reached a performance over 80% of correct trials in the 2-ACT were randomly assigned to control and restraint stress experimental groups. To analyze the effects of restraint stress on the auditory attention, trained rats of both groups were subjected to 50 2-ACT trials one day before and one day after of the stress period. A difference score was determined by subtracting the number of correct trials after from those before the stress protocol. Another set of rats was used to study the synaptic transmission in A1. Restraint stress decreased the number of correct trials by 28% compared to the performance of control animals (p < 0.001). Furthermore, stress reduced the frequency of spontaneous inhibitory postsynaptic currents (sIPSC) and miniature IPSC in A1, whereas glutamatergic efficacy was not affected. Our results demonstrate that restraint stress decreased auditory attention and GABAergic synaptic efficacy in A1. Copyright © 2013 IBRO. Published by Elsevier Ltd. All rights reserved.

Dietary restraint in college women: fear of an imperfect fat self is stronger than hope of a perfect thin self.

2012-09-01

We predicted that the perceived likelihood of acquiring a hoped-for thin self would mediate perfectionistic strivings on dietary restraint, and that the perceived likelihood of acquiring a feared fat self would mediate perfectionistic concerns on dietary restraint. We also predicted that the mediation pathway from perfectionistic concerns to dietary restraint would have a greater impact than that from perfectionistic strivings. Participants were 222 female college students who reported their height and weight and completed measures of perfectionism, the likelihood of acquiring the feared fat and hoped-for thin selves, and dietary restraint. Statistical analyses revealed that the perceived likelihood of acquiring the feared fat self mediated both perfectionistic concerns and perfectionistic strivings on dietary restraint, and that the mediating pathway from perfectionistic concerns to dietary restraint was greater than that from perfectionistic strivings. Implications for future research and eating pathology interventions are discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

The effect of physical restraints on fall rates in older adults who are institutionalized.

PubMed

Dunn, K S

2001-10-01

Since the Omnibus Budget Reconciliation Act (OBRA) of 1987, there has been a significant reduction in the use of physical restraints to prevent falls in older adults who are institutionalized because of the developing awareness of the physical and psychological problems associated with them. The purpose of this ex post facto descriptive study was to determine if there is a difference in falls when physical restraints are allowed or prohibited in one older adult population. Data from incident reports from a purposive sample of 97 older adults in one long-term care facility were analyzed before and after the implementation of a restraint-free policy. The results indicated no significant difference in the number of falls before and after the policy change. However, there was a significantly lower number of falls with injuries and a significantly higher number of falls without injuries. These findings suggest older adults will continue to fall with or without the use of physical restraints because of changes associated with the aging process and risk factors. Removing physical barriers from older adults and allowing freedom of movement may decrease the severity of injury sustained in a fall.

Satellite sound broadcasting system, portable reception

NASA Technical Reports Server (NTRS)

Golshan, Nasser; Vaisnys, Arvydas

1990-01-01

Studies are underway at JPL in the emerging area of Satellite Sound Broadcast Service (SSBS) for direct reception by low cost portable, semi portable, mobile and fixed radio receivers. This paper addresses the portable reception of digital broadcasting of monophonic audio with source material band limited to 5 KHz (source audio comparable to commercial AM broadcasting). The proposed system provides transmission robustness, uniformity of performance over the coverage area and excellent frequency reuse. Propagation problems associated with indoor portable reception are considered in detail and innovative antenna concepts are suggested to mitigate these problems. It is shown that, with the marriage of proper technologies a single medium power satellite can provide substantial direct satellite audio broadcast capability to CONUS in UHF or L Bands, for high quality portable indoor reception by low cost radio receivers.

Prevention of foot blisters.

Knapik, Joseph J

2014-01-01

Foot blisters are the most common medical problem faced by Soldiers during foot march operations and, if untreated, they can lead to infection. Foot blisters are caused by boots rubbing on the foot (frictional forces), which separates skin layers and allows fluid to seep in. Blisters can be prevented by wearing properly sized boots, conditioning feet through regular road marching, wearing socks that reduce reduce friction and moisture, and possibly applying antiperspirants to the feet. 2014.

Acute restraint stress decreases c-fos immunoreactivity in hilar mossy cells of the adult dentate gyrus

PubMed Central

Moretto, Jillian N.; Duffy, Áine M.

2017-01-01

Although a great deal of information is available about the circuitry of the mossy cells (MCs) of the dentate gyrus (DG) hilus, their activity in vivo is not clear. The immediate early gene c-fos can be used to gain insight into the activity of MCs in vivo, because c-fos protein expression reflects increased neuronal activity. In prior work, it was identified that control rats that were perfusion-fixed after removal from their home cage exhibited c-fos immunoreactivity (ir) in the DG in a spatially stereotyped pattern: ventral MCs and dorsal granule cells (GCs) expressed c-fos protein (Duffy et al., Hippocampus 23:649–655, 2013). In this study, we hypothesized that restraint stress would alter c-fos-ir, because MCs express glucocorticoid type 2 receptors and the DG is considered to be involved in behaviors related to stress or anxiety. We show that acute restraint using a transparent nose cone for just 10 min led to reduced c-fos-ir in ventral MCs compared to control rats. In these comparisons, c-fos-ir was evaluated 30 min after the 10 min-long period of restraint, and if evaluation was later than 30 min c-fos-ir was no longer suppressed. Granule cells (GCs) also showed suppressed c-fos-ir after acute restraint, but it was different than MCs, because the suppression persisted for over 30 min after the restraint. We conclude that c-fos protein expression is rapidly and transiently reduced in ventral hilar MCs after a brief period of restraint, and suppressed longer in dorsal GCs. PMID:28190104

A rear-seat air bag restraint device is disclosed that prevents an individual, or individuals, from continuing violent actions while being transported in a patrol vehicle`s rear seat without requiring immediate physical contact by the law enforcement officer. The air bag is activated by a control switch in the front seat and inflates to independently restrict the amount of physical activity occurring in the rear seat of the vehicle while allowing the officer to safely stop the vehicle. The air bag can also provide the officer additional time to get backup personnel to aid him if the situation warrants it. The bag is inflated and maintains a constant pressure by an air pump. 8 figs.

As physical restraints should only be used in exceptional cases, there is an urgent need for alternatives to restraint use. Surveillance technology could be such an alternative. This study explored whether nursing-home residents with dementia subjected to surveillance technology had better quality of life scores for mood, behavioral and societal dimensions than residents with physical restraints. Quality of life was assessed longitudinally, with three measurements in six psychogeriatric nursing homes of residents with surveillance technology (n = 170) and residents with physical restraints (n = 22). QUALIDEM subscales were used to measure five dimensions of quality of life. Multilevel longitudinal univariate and multivariate regression techniques were used to analyze the data. Because physical restraints were almost exclusively used in residents with low activities of daily living (ADL) independency (18 of the 22), we restricted the regression analyses to residents with a Barthel Index score ≤ 5 (overall n = 53). Univariate results showed that highly ADL-dependent residents with surveillance technology had significantly more positive affect than highly ADL-dependent residents with physical restraints. However, this difference proved to be no longer significant after adjustment for the confounders: age, sex and stage of dementia. Quality of life of highly ADL-dependent nursing-home residents with dementia seems to be unrelated to the use of surveillance technology as opposed to physical restraints.

Riskowski, JL; Dufour, AB; Hagedorn, TJ; Hillstrom, Howard; Casey, VA; Hannan, MT

2014-01-01

Objective Studies have implicated foot posture and foot function as risk factors for lower extremity pain. Empirical population-based evidence for this assertion is lacking; therefore, the purpose of this study was to evaluate cross-sectional associations of foot posture and foot function to lower extremity joint pain in a population-based study of adults. Methods Participants were members of the Framingham Foot Study. lower extremity joint pain was determined by the response to the NHANES-type question, “On most days do you have pain, aching or stiffness in your [hips, knees, ankles, or feet]?” Modified Arch Index (MAI) classified participants as having planus, rectus (referent) or cavus foot posture. Center of Pressure Excursion Index (CPEI) classified participants as having over-pronated, normal (referent) or over-supinated foot function. Crude and adjusted (age, gender, BMI) logistic regression determined associations of foot posture and function to lower extremity pain. Results Participants with planus structure had higher odds of knee (1.57, 95% CI: 1.24– 1.99) or ankle (1.47, 95% CI: 1.05–2.06) pain, whereas those with a cavus foot structure had increased odds of ankle pain only (7.56, 95% CI: 1.99–28.8) and pain at one lower extremity site (1.37, 95% CI: 1.04–1.80). Associations between foot function and lower extremity joint pain were not statistically significant, except for a reduced risk of hip pain in those with an over-supinated foot function (0.69, 95% CI: 0.51–0.93). Conclusions These findings offer a link between foot posture and lower extremity pain, highlighting the need for longitudinal or intervention studies. PMID:24591410

Few published studies have examined child passenger safety practices across countries. This study compared the prevalence and associated factors of child passenger restraint use among children, aged 0 to 17 in the state of Iowa in the United States, and the city of Shantou in China. Child restraint use observations were conducted in Iowa and in Shantou in 2012, respectively, among child passengers. Observations in Iowa were conducted at randomly selected gas stations, while in Shantou observations were completed at randomly selected schools or medical clinics. Research observers approached the driver, observed restraint use, and collected brief survey data. A total of 3049 children from Iowa and 3333 children aged 0 to 17 years from Shantou were observed. For children aged 0 to 3 years, only 0.1% were compliantly restrained in Shantou as compared to 95.9% in Iowa. The proportion of children who were compliantly restrained in Shantou increased with age, but generally decreased with age in Iowa. In Shantou, 36.0% of children aged 0 to 3 were sitting in the front seat as compared to only 1.7% of children of the same age in Iowa. Driver seat belt use was significantly associated with child restraint in both Iowa and Shantou; the association was stronger in Iowa than Shantou for all age groups. A significantly higher prevalence of children who were not appropriately restrained was observed in Shantou than in Iowa. Our findings support the need of mandatory child safety restraint use legislation in China.

1972-01-01

A description is given of a three dimensional hand force capability model for the seated operator and a biomechanical model for analysis of symmetric sagittal plane activities. The models are used to simulate and study human strengths for one and two handed tasks in zero gravity. Specific conditions considered include: (1) one hand active, (2) both hands active but with different force directions on each, (3) body bracing situations provided by portable foot restraint when standing and lap belt when seated, (4) static or slow movement tasks with maximum length of 4 seconds and a minimum rest of 5 minutes between exertions, and (5) wide range of hand positions relative to either the feet or bisection of a line connecting the hip centers. Simulations were also made for shirt sleeved individuals and for the male population strengths with anthropometry matching that of astronauts.

Diabetic neuropathy and foot complications.

PubMed

Boulton, Andrew J M

2014-01-01

Foot ulceration and Charcot neuroarthropathy (CN) are well recognized and documented late sequelae of diabetic peripheral, somatic, and sympathetic autonomic neuropathy. The neuropathic foot, however, does not ulcerate spontaneously: it is a combination of loss of sensation due to neuropathy together with other factors such as foot deformity and external trauma that results in ulceration and indeed CN. The commonest trauma leading to foot ulcers in the neuropathic foot in Western countries is from inappropriate footwear. Much of the management of the insensate foot in diabetes has been learned from leprosy which similarly gives rise to insensitive foot ulceration. No expensive equipment is required to identify the high risk foot and recently developed tests such as the Ipswich Touch Test and the Vibratip have been shown to be useful in identifying the high risk foot. A comprehensive screening program, together with education of high risk patients, should help to reduce the all too high incidence of ulceration in diabetes. More recently another very high risk group has been identified, namely patients on dialysis, who are at extremely high risk of developing foot ulceration; this should be preventable. The most important feature in management of neuropathic foot ulceration is offloading as patients can easily walk on active foot ulcers due to the loss of pain sensation. Infection should be treated aggressively and if there is any evidence of peripheral vascular disease, arteriography and appropriate surgical management is also indicated. CN often presents with a unilateral hot, swollen foot and any patient presenting with these features known to have neuropathy should be treated as a Charcot until this is proven otherwise. Most important in the management of acute CN is offloading, often in a total contact cast.

Depressed Affect and Dietary Restraint in Adolescent Boys’ and Girls’ Eating in the Absence of Hunger

Data suggest that depressed affect and dietary restraint are related to disinhibited eating patterns in children and adults. Yet, experimental research has not determined to what extent depressed affect acutely affects eating in the absence of physiological hunger (EAH) in adolescents. In the current between-subjects experimental study, we measured EAH in 182 adolescent (13-17y) girls (65%) and boys as ad libitum palatable snack food intake after youth ate to satiety from a buffet meal. Just prior to EAH, participants were randomly assigned to view either a sad or neutral film clip. Dietary restraint was measured with the Eating Disorder Examination. Adolescents who viewed the sad film clip reported small but significant increases in state depressed affect relative to adolescents who viewed the neutral film clip (p < .001). Yet, there was no main effect of film condition on EAH (p = .26). Instead, dietary restraint predicted greater EAH among girls, but not boys (p < .001). These findings provide evidence that adolescent girls’ propensity to report restrained eating is associated with their greater disinhibited eating in the laboratory. Additional experimental research, perhaps utilizing a more potent laboratory stressor and manipulating both affective state and dietary restraint, is required to elucidate how state affect may interact with dietary restraint to influence EAH during adolescence.

The capsular ligaments provide more hip rotational restraint than the acetabular labrum and the ligamentum teres

In this in vitro study of the hip joint we examined which soft tissues act as primary and secondary passive rotational restraints when the hip joint is functionally loaded. A total of nine cadaveric left hips were mounted in a testing rig that allowed the application of forces, torques and rotations in all six degrees of freedom. The hip was rotated throughout a complete range of movement (ROM) and the contributions of the iliofemoral (medial and lateral arms), pubofemoral and ischiofemoral ligaments and the ligamentum teres to rotational restraint was determined by resecting a ligament and measuring the reduced torque required to achieve the same angular position as before resection. The contribution from the acetabular labrum was also measured. Each of the capsular ligaments acted as the primary hip rotation restraint somewhere within the complete ROM, and the ligamentum teres acted as a secondary restraint in high flexion, adduction and external rotation. The iliofemoral lateral arm and the ischiofemoral ligaments were primary restraints in two-thirds of the positions tested. Appreciation of the importance of these structures in preventing excessive hip rotation and subsequent impingement/instability may be relevant for surgeons undertaking both hip joint preserving surgery and hip arthroplasty.

2015-11-01

Despite alarming prevalence rates, surprisingly little is known about neural mechanisms underlying eating behavior in juveniles with obesity. To simulate reactivity to modern food environments, event-related potentials (ERP) to appetizing food images (relative to control images) were recorded in adolescents with obesity and healthy adolescents. Thirty-four adolescents with obesity (patients) and 24 matched healthy control adolescents watched and rated standardized food and object images during ERP recording. Personality (impulsivity) and eating styles (trait craving and dietary restraint) were assessed as potential moderators. Food relative to object images triggered larger early (P100) and late (P300) ERPs. More impulsive individuals had considerably larger food-specific P100 amplitudes in both groups. Controls with higher restraint scores showed reduced food-specific P300 amplitudes and subjective palatability ratings whereas patients with higher restraint scores showed increased P300 and palatability ratings. This first ERP study in adolescents with obesity and controls revealed impulsivity as a general risk factor in the current obesogenic environment by increasing food-cue salience. Dietary restraint showed paradoxical effects in patients, making them more vulnerable to visual food-cues. Salutogenic therapeutic approaches that deemphasize strict dietary restraint and foster healthy food choice might reduce such paradoxical effects. © 2015 The Obesity Society.

Child restraint use in low socio-economic areas of urban Sydney during transition to new legislation.

Child restraints protect a young child against injury in crashes but best practice child restraint use is low in Australia, particularly among lower socio-economic groups. We investigated factors associated with restraint use to inform the development of education and distribution programmes to support new Australian legislation on child passengers among families in low socio-economic areas of metropolitan Sydney. We interviewed a parent or carer of 1160 children aged 2-5 years enrolled at one of 28 early childhood centres in low socio-economic areas of urban Sydney. Appropriate child restraint use was defined as a forward facing child restraint (FFCR) for 2-3 year olds and a FFCR or booster seat for children aged 4 years or more. Predictors of self-reported appropriate use were explored using logistic regression. Analysis was conducted on one child from each family in the target age range (2-5 years): 586 (51%) were male and the mean age was 3.5 (Standard Deviation 0.8) years. There were 432 (45%) families with annual income below $60,000, 248 (22%) spoke a language other than English at home and 360 (33%) had 3 or more children. Fifty-four percent of carers indicated that their 2-3 year old children travelled in a FFCR. Inappropriate use among children in this age group was more likely when the carer was <36 years (odds ratio (OR) 1.62, 95% confidence interval (CI) 1.08-2.45), in families with ≥3 children (OR 1.64, 95% CI 1.10-2.44) and when the carer believed that a booster seat was just as safe as a FFCR (OR 2.98, 2.05-4.32). Eight-eight percent of carers of 4-5 year olds reported use of a booster seat or FFCR. Non-use was associated with low household income (OR 3.10, 95% CI 1.67-5.75), in families with ≥3 children (OR 2.03, 95% CI 1.09-3.76) and families where a language other than English is spoken at home (OR 2.39, 95% CI 1.10-5.21). Non-English speaking families had less awareness of the new law and poorer knowledge of safety benefits of child

Distension-Induced Gastric Contraction is Attenuated in an Experimental Model of Gastric Restraint

PubMed Central

Lu, Xiao; Guo, Xiaomei; Mattar, Samer G.; Navia, Jose A.

2010-01-01

Background Gastric distension has important implications for motility and satiety. The hypothesis of this study was that distension affects the amplitude and duration of gastric contraction and that these parameters are largely mediated by efferent vagus stimulation. Methods A novel isovolumic myograph was introduced to test these hypotheses. The isovolumic myograph isolates the stomach and records the pressure generated by the gastric contraction under isovolumic conditions. Accordingly, the phasic changes of gastric contractility can be documented. A group of 12 rats were used under in vivo conditions and isolated ex vivo conditions and with two different gastric restraints (small and large) to determine the effect of degree of restraint. Results The comparison of the in vivo and ex vivo contractility provided information on the efferent vagus mediation of gastric contraction, i.e., the in vivo amplitude and duration reached maximum of 12.6 ± 2.7 mmHg and 19.8 ± 5.6 s in contrast to maximum of 5.7 ± 0.9 mmHg and 7.3 ± 1.3 s in ex vivo amplitude and duration, respectively. The comparison of gastric restraint and control groups highlights the role of distension on in vivo gastric contractility. The limitation of gastric distension by restraint drastically reduced the maximal amplitude to below 2.9 ± 0.2 mmHg. Conclusions The results show that distension-induced gastric contractility is regulated by both central nervous system and local mechanisms with the former being more substantial. Furthermore, the gastric restraint significantly attenuates gastric contractility (decreased amplitude and shortened duration of contraction) which is mediated by the efferent vagus activation. These findings have important implications for gastric motility and physiology and may improve our understanding of satiety. PMID:20706803

Various gloveboxes (GBXs) have been used aboard the Shuttle and ISS. Though the overall technical specifications are similar, each GBX's crew interface is unique. JSC conducted a series of ergonomic evaluations of the various glovebox designs to identify human factors requirements for new designs to provide operator commonality across different designs. We conducted 2 0g evaluations aboard the Shuttle to evaluate the material sciences GBX and the General Purpose Workstation (GPWS), and a KC-135 evaluation to compare combinations of arm hole interfaces and foot restraints (flexible arm holes were better than rigid ports for repetitive fine manipulation tasks). Posture analysis revealed that the smallest and tallest subjects assumed similar postures at all four configurations, suggesting that problematic postures are not necessarily a function of the operator s height but a function of the task characteristics. There was concern that the subjects were using the restrictive nature of the GBX s cuffs as an upper-body restraint to achieve such high forces, which might lead to neck/shoulder discomfort. EMG data revealed more consistent muscle performance at the GBX; the variability in the EMG profiles observed at the GPWS was attributed to the subjects attempts to provide more stabilization for themselves in the loose, flexible gauntlets. Tests revealed that the GBX should be designed for a 95 percentile American male to accommodate a neutral working posture. In addition, the foot restraint with knee support appeared beneficial for GBX operations. Crew comments were to provide 2 foot restraint mechanical modes, loose and lock-down, to accommodate a wide range of tasks without egressing the restraint system. Thus far, we have developed preliminary design guidelines for GBXs and foot.

Understanding socio-cultural factors associated with the development of dieting tendencies is important for preventing future disordered eating. We explored individual and socio-cultural factors associated with weight-focussed dietary restraint tendencies (described as dietary restraint) in 5-year-old girls. Participants were 111 5-year-old girls and 109 of their mothers. Girls were interviewed about their dietary restraint, body image, appearance ideals, positive weight bias (attributing positive characteristics to thinner figures), and peer conversations. Mothers completed self-report questionnaires assessing dietary restraint and appearance ideals, as well as measures reporting on their daughter's media exposure and peer appearance interest. Thirty-four percent of girls reported at least a moderate level of dietary restraint. While most girls were satisfied with their body size, half showed some internalization of the thin ideal. Girls' dietary restraint was correlated with weight bias favoring thinner bodies, and greater internalization of the thin ideal, media exposure, and appearance conversations with peers. Media exposure and appearance conversations were the strongest predictors of dietary restraint. These cross-sectional findings suggest that the socio-cultural environment of young girls may be important in the very early development of unhealthy dieting tendencies. Longitudinal research is necessary to identify whether these are prospective risk factors. © 2015 Wiley Periodicals, Inc.

The aim of this study was to investigate the role of foot morphology, related with respect to diabetes and peripheral neuropathy in altering foot kinematics and plantar pressure during gait. Healthy and diabetic subjects with or without neuropathy with different foot types were analyzed. Three dimensional multisegment foot kinematics and plantar pressures were assessed on 120 feet: 40 feet (24 cavus, 20 with valgus heel and 11 with hallux valgus) in the control group, 80 feet in the diabetic (25 cavus 13 with valgus heel and 13 with hallux valgus) and the neuropathic groups (28 cavus, 24 with valgus heel and 18 with hallux valgus). Subjects were classified according to their foot morphology allowing further comparisons among the subgroups with the same foot morphology. When comparing neuropathic subjects with cavus foot, valgus heel with controls with the same foot morphology, important differences were noticed: increased dorsiflexion and peak plantar pressure on the forefoot (P<0.05), decreased contact surface on the hindfoot (P<0.03). While results indicated the important role of foot morphology in altering both kinematics and plantar pressure in diabetic subjects, diabetes appeared to further contribute in altering foot biomechanics. Surprisingly, all the diabetic subjects with normal foot arch or with valgus hallux were no more likely to display significant differences in biomechanics parameters than controls. This data could be considered a valuable support for future research on diabetic foot function, and in planning preventive interventions. Copyright © 2012 Elsevier B.V. All rights reserved.

The purpose of this article was to synthesize the evidence regarding the reduction of physical restraint, and to seek some practical recommendations based on the current situation in China. Nine databases were retrieved; these were PubMed, CINAHL, MEDLINE, Trip Database, PsysINFO, Cochrane Library, CNKI (Chinese database), Wanfang (Chinese database) and CBM (Chinese database) respectively. The selected articles were screened manually, and the identified researches were appraised through Review manager 5.3. Eight studies (four randomized controlled trials and four quasi-experimental studies) published between June 2013 and May 2017 were selected. Risk ratios (RRs) with 95% confidence intervals (CIs) were used as the effect index for dichotomous variables. The standardized mean differences (SMDs) with 95% CIs were calculated as the pooled continuous effect. The outcome of meta-analysis suggested staff training reduced the duration (IV=-0.88; 95% CIs=-1.65 to -0.10; Z=2.22; p=0.03) and adverse effect (RR, 0.16; 95% CIs=0.09 to 0.30; Z=5.96; p<0.00001) of physical restraint, but there were no statistical change in the frequency of physical restraint (RR, 0.74; 95% CIs=0.43 to 1.28; Z=1.07; p=0.28). Noticeably, the result of pooled estimates from 3 RCTs suggested staff training had no effects on the incidence of physical restraint. (RR, 1.01; 95% CIs=0.45 to 2.24; Z=0.02; p=0.99) CONCLUSION: Staff training was an effective measure to minimize the duration and adverse effects of physical restraint. More studies are needed to examine the effectiveness of staff training in relation to reduce the prevalence of physical restraint. Furthermore, considering the nurse's education background in China, it is recommended to conduct a compulsory training program to reduce the unnecessary restraint. Copyright © 2017 Elsevier Inc.
