Study compared gait performance during a 5-minute walk among healthy subjects, people with spinal cord injury (SCI), and stroke survivors while investigating whether evaluating oxygen consumption during this test provides additional information about the subject's performance. Participants were fitted with a portable gas analyzer and walked on a 5-meter walkway for 5 minutes. Measures of walk distance, gait speed, gait energy expenditure, and gait cost were obtained, along with measures of ventilation, ventilation and carbon dioxide production slope, oxygen pulse, and heart rate. The SCI group walked less than the stroke survivors or the healthy group but had higher energy demands, as shown by gait energy expenditure and gait costs. Compared with the healthy group, the stroke group had higher ventilation and ventilation and carbon dioxide production slope. The results suggest that metabolic assessment during the 5-minute walk test is feasible with patients with neurological impairment.
