A preliminary model of wheelchair service delivery.

Objective: To integrate and expand on previously published models of wheelchair service delivery, and provide a preliminary framework for developing more comprehensive, descriptive models of wheelchair service delivery for adults with spinal cord injury within the U.S. health care system.

Quantifying wheelchair activity of children: a pilot study.

Objective: The purpose of this study was to investigate mobility-related wheelchair activity of children in their community setting.

Design: Mobility-related wheelchair activity data from 18 community-dwelling children (9 manual and 9 electric powered) were collected using custom-designed data logging devices. The children were between 8 and 17 yrs of age and independently used a wheelchair as their primary means of mobility.

Shoulder biomechanics during the push phase of wheelchair propulsion: a multisite study of persons with paraplegia.

Objectives: To present a descriptive analysis and comparison of shoulder kinetics and kinematics during wheelchair propulsion at multiple speeds (self-selected and steady-state target speeds) for a large group of manual wheelchair users with paraplegia while also investigating the effect of pain and subject demographics on propulsion.

Design: Case series.

Setting: Three biomechanics laboratories at research institutions.

Assessing mobility characteristics and activity levels of manual wheelchair users.

Although engaging in an active lifestyle is beneficial for maintaining quality of life, a majority of wheelchair users are inactive. This study investigated the mobility characteristics and activity levels of manual wheelchair users in the residential setting and at the National Veterans Wheelchair Games (NVWG). Demographic factors that may have influenced activity in the home environment were also identified.

Multisite comparison of wheelchair propulsion kinetics in persons with paraplegia.

A multisite collaborative study is being conducted on the association between propulsion biomechanics and upper-limb injuries. This substudy compared subject characteristics and pushrim kinetics across three sites and identified early on in the main study any differences that could affect interpretation of the findings or data pooling. A total of 42 manual wheelchair users with paraplegia (14 from each site) performed 0.

Issues in maintenance and repairs of wheelchairs: A pilot study.

In this pilot study, we assessed wheelchair durability and its effect on user satisfaction. Specifically, we examined the characteristics of the participants' wheelchairs, the types of maintenance and repairs completed, and whether the participants' satisfaction was affected by problems with their wheelchairs. A convenience sample of 130 participants who used wheelchairs as their primary means of mobility was recruited.
