All subjects walked at their preferred speed on a figureof- eight track. Normal subjects also walked at slower and faster speeds. Oxygen consumption, heart rate and rating of perceived exertion were measured. In normal subjects, stable heart rates (±2 beats/min) were rapidly reached within two minutes at all three speeds. In paraplegics, the heart rate responses were more variable. The heart rate response in lumbar level paraplegics resembled normal subjects. Thoracic level paraplegics rarely showed stable heart rates during walking and in some instances, the rate rose progressively up to values of about 180 beats/min. In normal subjects walking in knee-ankle-foot orthoses, there was no significant difference of energy cost and physiological cost index between preferred and fast speeds. The preferred and fast speeds were also more efficient for crutch walling. There was a significant correlation (p SP - 209 EP - 217 AU - OKHOVATIAN, F AU - BAXENDALE, RH AU - SPURWAY, NC AD - From the Faculty of Rehabilitation, Shahid Beheshti University of Medical Sciences, Tehran, Iran KW - Arm Crank Ergometry KW - Crutch Walking KW - Energy Cost KW - Energy Expenditure KW - Oxygen Consumption KW - Paraplegic KW - Perceived Exertion KW - Physiological Cost Index KW - Upper Body Exercise.
