The purpose of this study was to evaluate the effects of a structured hand cycle training program in individuals with chronic tetraplegia. Twenty-two patients with tetraplegia (American Spinal Injury Association Impairment Scale classification A-D) at least 2 years since injury participated. The intervention was an 8- to 12-week hand cycle interval training program. Primary outcomes of physical capacity were: peak power output (POpeak) and peak oxygen uptake (Vo2peak), as determined in hand cycle peak exercise tests on a motor-driven treadmill. Secondary outcome measures were: peak muscle strength of the upper extremities, respiratory function and participant-reported shoulder pain.
The results showed that patients with tetraplegia were able to improve their physical capacity through regular hand cycle interval training, without participant-reported shoulder-arm pain or discomfort.
