ABSTRACT
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 OUTCOMEMEASURES:
Oxygen consumption per unit time (VËO2, mL/min/kg), velocity (m/min), cost of transport (VËO2/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), VËO2 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.Key words
