Objective To examine the cardiorespiratory responses of patients with spinal cord injury (SCI) paraplegia using a motor driven rowing machine. Method Ten SCI patients with paraplegia [A (n=6), B (n=1), and C (n=3) by the American Spinal Injury Association impairment scale] were selected. Two rowing techniques were used. The first used a fixed seat with rowing achieved using only upper extremity movement (fi xed rowing). Th e second used an automatically moving seat,facilitating active upper extremity movement and passive lower extremity movement via the motorized seat (motor rowing). Each patient performed two randomly assigned rowing exercise stress tests 1-3 days apart. Th e work rate (WR), time, respiratory exchange ratio (R), oxygen consumption (VO2), heart rate (HR), metabolic equivalents (METs), and rating of perceived exertion (RPE) were recorded. Results WR, time, VO2, and METs were significantly higher after the motor rowing test than after fixed motor rowing test (p<0.05). HR after motor rowing was signifi cantly lower than fi xed rowing (p<0.05). Conclusion Cardiorespiratory responses as VO2, HR and METs can be elicited by the motor rowing for people with paraplegic SCI.
