Individuals with cognitive disabilities have challenges personal navigation and wayfinding, especially when traveling on public transportation. The purpose of this case study is to describe the structure implementation Personal Navigation for Disabilities (PNID) education training program, which based a socio-technical architecture individuals within fixed-route bus system. A methodology was used preliminary findings skills, attributes, experiences three as it relates transportation systems...

Introduction: The wheelchair service delivery process (SDP) is a large complex system and therefore has many potential points of failure; determining priorities for improvement challenging. complexities introduce several barriers to accessing maintaining wheelchairs individuals with mobility impairments. Given the breadth depth barriers, it important know in which areas focus future policy reform efforts.

Wheelchair part failures and repairs have significantly increased over the last decade, leading to severe consequences for wheelchair users. Servicing these devices by repair technicians has reduced failures. However, no tools or technologies been developed support servicing in practice. To inform events, risk factors affecting quality reliability need be identified. This pilot study tracks usage a week community eight ultralight manual users assesses relationship between variables...

Spider silk is a high-performance biomaterial with exceptional mechanical properties and over half century of research into its mechanics, structure, biology. Recent demonstrates that it highly variable class materials differs across species individuals in complex interesting ways. Here, we review recent literature on variation evolution spider silk. We then present new data material from nine spiders the Mesothelae Mygalomorphae, two basal clades spiders. Silk Araneomorphae (true where most...

The purposes of this article were to examine the existing 2005 Clinical Practice Guidelines for preservation upper extremities in spinal cord injury and explore literature determine what might need be included an update. This is a consensus position based on review expertise authors. findings support original recommendations provide evidence that suggests information regarding equipment skills training as well impact caregivers needed.

Although the exposure to whole-body vibrations (WBV) has been shown be detrimental seated humans, effects of wheelchairs and seating systems on transmission vibration an individual have not thoroughly examined. The purpose this study was determine if selected wheelchair seat cushions back supports minimize vibrations. Thirty-two users traversed activities daily living course three times using 16 randomly as well their own. Vibrations were measured triaxial accelerometers at participant's...

A multisite collaborative study is being conducted on the association between propulsion biomechanics and upper-limb injuries. This substudy compared subject characteristics pushrim kinetics across three sites identified early in main any differences that could affect interpretation of findings or data pooling. total 42 manual wheelchair users with paraplegia (14 from each site) performed 0.9 m/s 1.8 steady state trials an acceleration-brake-coastdown trial a dynamometer while forces moment...

Whole-body vibration exposure has been found to be detrimental the health of humans owing effects such as degraded comfort, disc degeneration, and lower back pain. The purpose this study was determine if selected seat cushions supports minimize transmission vibrations during manual wheelchair propulsion. Ten unimpaired participants traversed an activities daily living course using four supports. Vibrations were measured triaxial accelerometers. time domain frequency transmissibility used...

The manual wheelchair has undergone much advancement over the past two decades. purpose of this article is to provide an overview most significant advances in wheelchairs. These technological are now available clinical setting and should be recognized, discussed, adopted by doctors, clinicians, engineers, funding sources, and, important, consumers when appropriate being selected.

Objective: To compare the kinetics of manual wheelchair (MWC) propulsion on ramps varying slopes that may be encountered when accessing large accessible transit vehicles (LATVs).Design: Observational study.Setting: Biomechanics research laboratory.Participants: A convenience sample able-bodied adults (n = 7) having no experience propelled a MWC slope 3.5°, 9.5° and 15°.Interventions: Not applicable.Main outcome measures: Resultant (Fres), radial (Fr) tangential (Ft) forces applied to...

The purpose of this study was to describe the frequency content racing wheelchair propulsion motion data. selection filter corner in previous kinematic analyses manual commonly based on gait literature. An estimate separating signal and noise determined make recommendations for low-pass digital filters. global (noncoordinate specific) cutoff 6 Hz. directional frequencies were 5.1, 3.9, 5.6 Hz, anterior-posterior, superior-inferior medial-lateral directions, respectively. Recommendations...

The purpose of the paper is to mathematically model a manual wheelchair on dynamometer and flat tile floor respectively, using simplified version R.A. Cooper's (J. Rehabil. Res. Dev., vol. 27, no. 2, p. 151-62, 1990). Then compared measured data from coast down trials pearson-product correlation coefficient. Using 2nd order polynomial rear wheel angular position as function time we obtained coefficients which ranged 0.9988 1.0000 with mean 0.9998. From 2/sup nd/ authors were able measure...

Aim: This brief report provides an overview of the development and structure Health App Review Tool. Methods: The Tool has been designed to assess smart phone health apps according their compatibility individuals within Alzheimer's disease community. Specifically, app features functions are characterized appropriateness needs, abilities, preferences potential users. is comprised two components, User Assessment; each component includes four complementary domains. Items in these domains can be...
