A review of wheelchair research within the scope of the wheelchair as a means of daily ambulation is presented. The relevance of a combined biomechanical and physiological research approach is advocated for enhancing the body of knowledge of wheelchair ergonomics, that is, the wheelchair/user interaction in relation to aspects of vehicle mechanics and the user’s physical condition. Results of experiments regarding variations in the wheelchair/user interface stress the possibilities of optimization in terms of wheelchair dimensions and user characteristics. Analysis of propulsion technique is aimed at the within-cycle characteristics and the time-dependent organization of technique.

Background:

The objective was to determine the test-retest reliability and criterion validity of the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD).

Methods:

Forty-five non-wheelchair dependent subjects were recruited from three Dutch rehabilitation centers. Subjects’ diagnoses were: stroke, spinal cord injury, whiplash, and neurological-, orthopedic- or back disorders. The PASIPD is a 7-d recall physical activity questionnaire that was completed twice, 1 wk apart. During this week, physical activity was also measured with an Actigraph accelerometer.

Results:

The test-retest reliability Spearman correlation of the PASIPD was 0.77. The criterion validity Spearman correlation was 0.30 when compared to the accelerometer.

Conclusions:

The PASIPD had test-retest reliability and criterion validity that is comparable to well established self-report physical activity questionnaires from the general population.
