New geared wheelchair wheels have been developed allowing the user to pull backwards on the rims to move forward. Theoretically, this utilizes larger muscle groups compared to conventional propulsion preventing repetitive stress injuries. This study compared the gross mechanical efficiency (GME), perceived effort and energy expenditure of propelling the wheelchair using two types of these geared wheels and standard forward propulsion wheels. A within participants repeated measures design was used. Participants' energy expenditure and perceived exertion were measured...

Blind people adopt their remaining intact senses to perceive the world for tasks such as determining the water level in a bowl. Pouring water into a bowl generates water sounds and echoes reflected in the bowl. This research develops a bowl with increased echo (called an echo bowl), and analyzes the accuracy of water levels perceived by visually impaired people using a container or a kettle to pour water into a common bowl or an echo bowl. The analysis of factors of pouring and filled equipment indicates that the container has a significantly lower water level error than the kettle when pouring water...

The importance of adaptive seating system on body structure and function is widely accepted, but its impact on psychosocial aspects needs more consideration by health professionals. This article describes the Italian validation of the Psychosocial Impact of Assistive Device Scale (IT-PIADS) for non-ambulant people with neuromotor disorders. Once agreement has been given by the original authors, the scale was translated and adapted to the Italian culture. The IT-PIADS was administered to different wheelchairs users with heterogeneous diagnosis...

The medical and social models of disability are based on a dichotomy that categorizes people as able-bodied or disabled. In contrast, the biopsychosocial model, which forms the basis for the International Classification of Functioning, Disability and Health (ICF), suggests a universalistic perspective on human functioning, encompassing all human beings. In this article we argue that the artificial separation of function-enhancing technology into assistive technology (AT) and mainstream technology might be one of the barriers to a universalistic view of human functioning...

The high prevalence of shoulder pain in using walkers in patients who have spinal cord injury (SCI). Also, the limited options available to economically measure grip forces in walkers, which drove the need to create one. This article describes a method to obtain upper-extremities' forces and moments in a person with SCI by designing an appropriate instrumented walker. First, since the commercial multidirectional loadcells are too expensive, custom loadcells are fabricated. Ultimately, a complete gait analysis by means of VICON motion analysis and using inverse dynamic method has been held to measure upper-extremities' efforts...

INTRODUCTION: To initiate appropriate interventions and avoid physical decline, comprehensive measurements are needed to detect functional changes in elderly people at the earliest possible stage. The established Timed Up&Go (TUG) test takes little time and, due to its standardized and easy procedure, can be conducted by elderly people in their own homes without clinical guidance. Therefore, cheap light barriers and force sensors are well suited ambient sensors that could easily be attached to existing (arm)chairs to measure and report TUG times in order to identify functional decline...

The goals of knee rehabilitation are to improve range of motion and muscle status. The aim of the study was to investigate accuracy and reproducibility of a newly designed knee-training device (KT) under standardized laboratory conditions. Two application-based software programs, one to measure maximum force and the other intended to improve users' coordination were developed to be used on a tablet during exercises, wirelessly connected to KT placed under the popliteal fossa. KT was loaded for 20 intervals of 15 seconds (s) ranging between 0-350 Newton (N) each...

This study compared the effectiveness of two assistive technologies to accommodate the word reading skills of four middle school students with reading learning disabilities. Kurzweil 3000 is a continuous text-to-speech (TTS) computer software program that allows students to follow along on a computer monitor while passages are read aloud. A reading pen is a discontinuous TTS assistive technology (AT) device that allows students to scan and hear selected words read aloud. An adapted alternating treatments design was implemented to compare the effects of listening-while-reading using continuous TTS AT, discontinuous TTS AT, and silently reading without accommodation on reading comprehension accuracy and rate...

Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) has published a position paper strongly advocating powered mobility (PM) for children with severe physical limitations (Rosen et al., 2009). Many studies have established that there are gains in social skills and functional mobility. While PM can aid independence, there has been more emphasis on the improvements in socialization rather than the positive changes PM can make in a child's daily living. For example, Bottos and colleagues stated the quality of life did not change for the children in their study (2001)...

Recently, a few software applications (apps) have been developed to enhance vocabulary and conceptual networks to address the needs of children with language impairments (LI), but there is no evidence about their impact and their usability in therapy contexts. Here, we try to fill this gap presenting a system aimed at improving the semantic competence and the structural knowledge of children with LI. The goal of the study is to evaluate learnability, usability, user satisfaction and quality of the interaction between the system and the children...

Hysteresis and impact damping measures were made on 37 wheelchair seating cushions according to ISO 16840-2:2007 Wheelchair seating-Part 2: Determination of physical and mechanical characteristics of devices intended to manage tissue integrity-seat cushions. These measures were then correlated using Spearman and Pearson correlations to investigate the relationship between them. Correlations were also conducted on the subset of cushions comprising only those with planar foam construction. Correlation between the hysteresis measures (h250 and h500) and the mean number of rebounds greater in amplitude than 10% of the peak acceleration amplitude (R10%) were weak, as were the correlations between the hysteresis measures and the mean peak first rebound acceleration (aa)...
