A novel portable and cost-efficient wheelchair training roller for persons with disabilities in economically disadvantaged settings: the EasyRoller

Prescription methodology integrated with equipment designed for customising racing wheelchair

BACKGROUND

Wheelchair racing is a traditional modality of Paralympic athletics. In general, racing wheelchairs are customized according to the athletes' anthropometric conditions, based on pre-established dimensions according to the manufacturer's manual. Usually, athletes choose the dimensions for their new sports wheelchairs, and when they are delivered for use, they often have problems due to incorrect body adjustments.

PURPOSE

To develop a new customization methodology that is made possible through a new multi-adjustable racing wheelchair prescription equipment (RWPE) for athletics. This equipment performs several measurements and adjustments according to the athlete's anthropometric characteristics, evaluating the best-fit athlete to obtain better performance in the personalized wheelchair.

MATERIALS AND METHODS

Customizing racing wheelchairs is based on anthropometric measurements of the individual and specific ergonomic adjustments for better performance and safety. The RWPE is a multi-adjustment device composed of modules that use measuring instruments to guarantee maximum precision and accuracy of the assessments. This project's innovation is associated with the multi-regulation equipment itself and a conventional process of manufacturing a racing wheelchair through an online form. The RWPE has a robust and rigid structure for conducting race-track experimental tests.

RESULTS AND CONCLUSIONS

The experimental tests allowed the equipment to be validated regarding safety, comfort, and prescription methodology. A high-performance athlete validated the equipment and prescription methodology, and as a result, a new version of a parameterized wheelchair was also developed using the prescription methodology. A comparison between prescription tests showed better athlete performance regarding estimated average power, considering dimensions optimized through RWPE.

Socio-ecological Barriers to Leisure Time Physical Activity in Spanish Wheelchair Users With Spinal Cord Injury: Associations With Sociodemographic Characteristics and Functional Independence

OBJECTIVE

(1) To assess prevalence and severity of socio-ecological barriers to leisure time physical activity (LTPA) in a sample of adults with spinal cord injury (SCI); (2) to examine the association of these barriers with sociodemographic characteristics and functional independence (FI); and (3) to explore which socio-ecological levels of barriers might be associated with LTPA.

DESIGN

Cross-sectional study.

SETTING

Neurorehabilitation Hospital specialized in SCI.

PARTICIPANTS

207 wheelchair users with SCI living in the community who attended a comprehensive check-up (22.7% women, 47.5±10.7 mean age; N=207).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The short version of the Barriers to Physical Activity Questionnaire for People with Mobility Impairments was used to measure socio-ecological barriers to LTPA. The Spinal Cord Independence Measure III was used to measure FI. The Physical Activity Recall Assessment for People with SCI was used to quantify LTPA. Several multiple linear regression models were computed to examine the associations between socio-ecological barriers and sociodemographic factors, LTPA and FI.

RESULTS

A high prevalence of barriers to LTPA was found. Seven of these barriers (2 intrapersonal, 3 organizational, and 2 community) were present for >60% of the participants. Intrapersonal and organizational barriers had a higher effect on participants with lower FI and women. Interpersonal barriers were higher for older participants and with lower FI, while community barriers were higher for unemployed participants. Finally, intrapersonal and interpersonal barriers were negatively associated with LTPA, and FI revealed as a moderator of the intrapersonal barriers-LTPA relation.

CONCLUSIONS

Given their high prevalence and their association with LTPA, the development of interventions targeting socio-ecological barriers to LTPA in people with SCI becomes crucial. The associations of these barriers with FI and sociodemographic characteristics should also be considered for these interventions to be as specific and effective as possible.

Subjective Perception of Individuals with Physical Disabilities Regarding Exercise Equipment Use

Rehabilitation exercise is effective for improving the health of persons with physical disabilities. However, there are limited studies on their perception of exercise equipment use. The purpose of this study was to investigate the subjectivity to understand the types of perceptions of individuals with physical disabilities regarding the use of exercise equipment in South Korea. This study used Q-methodology. A literature review and focus group interviews with individuals with physical disabilities were conducted to construct Q-Population. Q-statements were selected from the Q-population, after which Q-sorting was executed by P-sample. The results indicated 4 perception types: (1) "Independent user," (2) "Practical user," (3) "Motivational user," and (4) "Convenience user." Recommendations were provided for developing exercise equipment for use by individuals with physical disabilities. This study revealed 4 perception categories and the findings have strong potential to contribute to the development of proper services and the effective utilization of exercise equipment for individuals with physical disabilities.
