Evaluation of a pushrim-activated, power-assisted wheelchair.

摘要: Abstract Cooper RA, Fitzgerald SG, Boninger ML, Prins K, Rentschler AJ, Arva J, O'Connor TJ. Evaluation of a pushrim-activated, power-assisted wheelchair. Arch Phys Med Rehabil 2001;82:702-8. Objective: To evaluate novel wheelchair (PAPAW) for compliance with standards, metabolic energy cost during propulsion, and ergonomics selected activities daily living (ADLs). Design: A 3-phase study, the second third which were repeated-measures designs. Setting: rehabilitation engineering center within Veterans Affairs medical center. Patients: Eleven full-time, community-dwelling, manual users (4 women, 6 men) spinal cord injuries or multiple sclerosis. Interventions: Phase 1: Compliance testing, test dummy, in accordance standards American National Standards Institute Rehabilitation Engineering Assistive Technology Society North America. 2: Metabolic consumption testing—at 2 speeds 3 resistance levels—in subjects' PAPAW. 3: ability to perform ADLs PAPAW compared subjects personal Main Outcome Measures: The PAPAW's static stability, strength, impact fatigue environmental response, obstacle climbing ability, range, maximum speed, braking distance. Subjects' oxygen per minute, minute ventilation, heart rate different workloads their own wheelchairs. Subject ratings perceived comfort basic while performing ADLs. Completion time, stroke frequency, each ADL. Results: was found be standards. With PAPAW, user had significantly lower (VO mL/min: p mL/kg × min: =.001), receiving ratings. Conclusion: This study indicated that is compliant reduces demand placed on rated its favorably when PAPAWs may provide wheelchairs less physiologically stressful means mobility few adaptations vehicle home environment. © 2001 by Congress Medicine Academy Physical
