Objective
To determine the cardiometabolic demands associated with exoskeletal-assisted walking (EAW) in persons with paraplegia. This study will further examine if training in the device for 60 sessions modifies cost of transport (CT). Design Prospective cohort study. Measurements over the course of a 60-session training program, approximately 20 sessions apart. Setting James J. Peters Bronx Veterans Affairs Medical Center, Center for the Medical Consequences of Spinal Cord Injury Research Center. Participants The participants demographics (N=5) were 37-61 years old, body mass index (calculated as weight in kilograms divided by height in meters squared) of 22.7-28.6, level of injury from T1-T11, and 2-14 years since injury. Interventions Powered EAW. Main Outcome Measures Oxygen consumption per unit time (O2, mL/min/kg), velocity (m/min), cost of transport (O2/velocity), and rating of perceived exertion (RPE). Results With training: EAW velocity significantly improved (Pre: 51±51m; 0.14±0.14m/s vs Post: 99±42m; 0.28±0.12m/s, P=.023), RPE significantly decreased (Pre: 13±6 vs Post: 7±4, P=.001), O2 significantly improved (Pre: 9.76±1.23 mL/kg/m vs Post: 12.73±2.30 mL/kg/m, P=.04), and CT was reduced from the early to the later stages of training (3.66±5.2 vs 0.87±0.85 mL/kg/m). Conclusions The current study suggests that EAW training improves oxygen uptake efficiency and walking velocities, with a lower perception of exertion. |
