Quantification of activity during wheelchair basketball and rugby at the National Veterans Wheelchair Games: A pilot study.

To date, no published data exists on distances and speeds traveled by rugby or basketball players during game play. The purpose of this study was to provide quantitative information of selected characteristics of wheelchair basketball and rugby game play. A miniaturized data logger was used to collect the distance traveled, average velocity, activity time, and number of starts and stops during basketball and rugby games. Participants were recruited prior to wheelchair basketball and rugby tournaments during the 2007 and 2008 National Veterans Wheelchair Games. Inclusion criteria were age 18 years or older and been participating in wheelchair basketball or rugby. The wheelchair rugby athletes on average traveled 2364.78 ± 956.35 meters at 1.33 ± 0.25 m/sec with 242.61 ± 80.31 stops and starts in 29.98 ± 11.79 min of play per game. The wheelchair basketball athletes on average traveled 2679.52 ± 1103.66 m at 1.48 ± 0.13 m/sec with 239.78 ± 60.61 stops and starts in 30.28 ± 9.59 min of play per game. Previous research has not reported basketball or rugby game play variables such as these, making this data set unique. The information could be used by players and coaches to create training protocols to better prepare for game conditions.

Psychosocial impact of participation in the National Veterans Wheelchair Games and Winter Sports Clinic

Purpose. The purpose of this study was to determine the characteristics of individuals who participate in the National Veterans Wheelchair Games (NVWG) and the Winter Sports Clinic (WSC) for veterans with disabilities. In addition, it was of interest to determine how these events had impacted their lives. Method. Participants were recruited at the 20th Winter Sports Clinic, held in Snowmass Colorado and the 26th National Veterans Wheelchair Games held in Anchorage, Alaska. Data of interest included demographic, sport participation information, community integration, self-esteem, and quality of life. A secondary data analysis was completed to determine how comparable individuals who attended the NVWG/WSC were to individuals who did not participate in these events. Results. The 132 participants were a mean age of 47.4 + 13.4 and lived with a disability for an average of 13.4 + 12.1. Participants felt that the NVWG/WSC increased their knowledge of sports equipment (92%), learning sports (89%), mobility skills (84%), and acceptance of disability (84%). The majority of participants stated that the NVWG/WSC improved their life. Of those who participated at the NVWG/WSC, they tended to be more mobile, but have increased physical and cognitive limitations as measured by the CHART when compared to the non-attendees. Conclusions. Recommending veterans participate in events such as the NVWG and WSC can provide psychosocial benefits to veterans with disabilities.

Personal Mobility and Manipulation Appliance—Design, Development, and Initial Testing

The ability to perform activities of daily living and mobility-related activities of daily living are substantial indicators of ones ability to live at home and to participate in ones community. Technologies to assist with mobility and manipulation are among the most important tools that clinicians can provide to people with disabilities to promote independence and community participation. For people with severe disabilities involving both the upper and lower extremities, there are few systems that provide practical and coordinated assistance with mobility and manipulation tasks. The personal mobility and manipulation appliance (PerMMA) was created in response to goals set forth by a team of clinicians and people with disabilities.

The development of a nationwide registry of wheelchair users

This paper provides an overview of the development of a wheelchair users registry and subsequently describes a population of individuals who use wheelchairs. The characteristics of Americans who permanently use wheelchairs and scooters are currently unknown. As the result of developing a Registry of individuals who use wheeled mobility devices for systematic recruitment for research studies, this study provides a description of a nationwide sample of over 1000 individuals who used wheelchairs or scooters for their daily mobility. The Registry is predominantly Caucasian (83%), 63% male, with a mean age of 50 years. Some 54% used manual wheelchairs for an average of 16 years. When quality of wheelchairs was compared, results indicated those in more customizable manual wheelchairs were significantly more likely to be younger. Males were significantly more likely to receive more customizable, heavy duty power wheelchairs than females. The Wheelchair Users Registry provides an organized and systematic way to maintain contact with previous research participants. Expected to grow in size, the Registry may enable an even more diverse pool of subjects interested in participating in research studies.

Demographic profile of older adults using wheeled mobility devices

The purpose of this study was to determine whether the use of wheeled mobility devices differed with respect to age, gender, residential setting, and health-related factors among older adults. A total of 723 adults ageing 60 and older are representing three cohorts, from nursing homes, the Center for Assistive Technology, and the wheelchair registry from the Human Engineering Research Laboratories. Wheeled mobility devices were classified into three main groups: manual wheelchairs, power wheelchairs, and scooters. Our results found factors including age, gender, diagnosis, and living settings to be associated with differences in use of manual versus powered mobility devices. Differences in use were also noted for subtypes of manual (depot, standard, and customized) and powered (scooter, standard, and customized) mobility devices, on demographic, living arrangements, and health-related factors. Consideration of demographic, health-related, and environmental factors during the prescription process may help clinicians identify the most appropriate mobility device for the user.

Manual Wheelchair Propulsion Over Cross-Sloped Surfaces: A Literature Review

ABSTRACT Manual wheelchair propulsion may be facilitated or impeded depending upon the surface and the environment. One barrier may be the cross-slope of pathways. The purpose of this systematic literature review was to determine the quality of the evidence on the effects of cross-slopes on manual wheelchair propulsion. The goal was to identify and to understand the optimal design for cross-slopes that have the least negative impact for wheelchair users. Fifty-two articles were reviewed by 15 expert reviewers. Six were identified to be relevant to propulsion over cross-slopes. Most studies agree that traversing a cross-slope in a manual wheelchair is more difficult than propelling on a level surface. However, agreement has not been reached as to the percentage increase in effort or the optimal degree of cross-slopes that should be used as an acceptable standard. There is a paucity of research investigating the impact of cross-slopes on wheelchair mobility and community participation.

Design and User Evaluation of a Wheelchair Mounted Robotic Assisted Transfer Device

Purpose. The aim of this study is to describe the robotic assisted transfer device (RATD) and an initial focus group evaluation by end users. The purpose of the device is to aid in the transfers of people with disabilities to and from their electric powered wheelchair (EPW) onto other surfaces. The device can be used for both stand-pivot transfers and fully dependent transfers, where the person being transferred is in a sling and weight is fully on the robot. The RATD is fixed to an EPW to allow for its use in community settings. Method. A functional prototype of the RATD was designed and fabricated. The prototype was presented to a group of 16 end users and feedback on the device was obtained via a survey and group discussion. Results. Thirteen out of sixteen (83%) participants agreed that it was important to develop this type of technology. They also indicated that user, caregiver, and robotic controls were important features to be included in the device. Conclusions. Participants in this study suggested that they would be accepting the use of robotic technology for transfers and a majority did not feel that they would be embarrassed to use this technology.

Investigation of the Impact of Sports, Exercise, and Recreation Participation on Psychosocial Outcomes in a Population of Veterans with Disabilities: A Cross-sectional Study.

ObjectiveThe aim of this study was to investigate possible effects that participation in sports, exercise, and recreation may have on self-esteem and quality-of-life in service members/veterans with disabilities. DesignTwo hundred twenty service members/veterans with disabilities who were participants in one of three annual adaptive sporting events took part in this cross-sectional study. Variables of interest were years of sport, exercise, and recreation participation since the onset of disability as well as the type of activity they engaged in. Main outcome measures were self-esteem and quality-of-life. ResultsA positive relationship was found between participant quality-of-life and the number of years spent participating in sports, exercise, and recreation since the onset of their disability. A significant difference was found between pre-event and postevent self-esteem scores. A significant difference was also found in self-esteem scores between the levels of years of participation in sports, exercise, and recreation when averaged across activity type. Finally, there were significant differences found on self-esteem scores between the levels of type of activity averaged across years of participation. ConclusionsOur results indicate that participation in sports, exercise, and recreation has a positive influence on self-esteem and quality-of-life in individuals with disabilities.

Effects of cross slopes and varying surface characteristics on the mobility of manual wheelchair users.

ABSTRACT Surface characteristics of a cross slope can impact the ease with which a manual wheelchair (MWC) user propels across a surface. The purpose of this research was two-fold. Phase I of this research surveyed MWC users to identify cross slope scenarios that they reported to be more difficult to traverse compared to other common driving obstacles. Our survey results showed that, overall, cross slopes were harder to propel across than narrow and manual doors, and cross-slopes in inclement weather conditions were equal or more difficult than gravel and rough-surfaces. Cross slopes with severe angles and those with compound angles (slope with cross-slope) were the most difficult to traverse. Phase II focused on identifying the responses (e.g., avoid, explore alternative, experience a sense of insecurity, no effect) people had when viewing pictures of various cross-slopes scenarios (e.g., narrow space, compound angles, extreme weather) that wheelchair users encounter. These results showed that people reported that they would avoid or feel insecure on some cross-sloped surfaces, like the weather, that are not within our control, others, like compound angle and curb-cuts on slopes, that can be addressed in the construction of pathways or sidewalks.
