title: Relationship of impairment and functional ability to habitual activity and fitness following spinal cord injury.
abstract: Associations between a physically active leisure, physical fitness, impairment and disability have been tested in 123 volunteers (73 with paraplegia and 50 with quadriplegia). Active physical leisure was assessed by the questionnaire of Godin and Shephard (Canadian Journal of Sports Sciences 10, 141-6 1985). Fitness measures included body mass index, peak oxygen intake on a wheelchair ergometer, and tests of muscle strength and endurance (peak isokinetic torque, average muscle power and total muscle work for shoulder flexion, shoulder adduction and elbow flexion at movement speeds of 60 degrees and 180 degrees s-1). Primary impairment was assessed by the ISMGF scale, and secondary impairment was judged from reported pressure scores, spasticity, and urinary infections over the previous 12 months. Scores for self-care and mobility were obtained using a modified Barthel Index. Physically active leisure and fitness were unrelated to secondary impairment. However, functional ability for a given primary impairment was significantly correlated with peak oxygen intake and the three indices of muscle strength, particularly in individuals with high level lesions. Associations between physical activity and functional ability were weaker, but tended in the same direction. Although longitudinal studies are needed to prove the causality of these relationships, the findings point towards a significant influence of fitness status upon functional ability. Rehabilitation teams should thus give a stronger emphasis to systematic exercise conditioning programmes when planning overall treatment following SCI.
