• Aim– Investigate energy expenditure and heart rate (HR)
during powered exoskeletal-assisted use during sitting, standing, and walking.
• Relevance– Recent technological advances have led to
development of powered exoskeletal devices that enable gait in persons with paralysis.• However, energy expenditure required to use powered
exoskeleton has not been reported.

Method
• 8 nonambulatory persons with paraplegia were trained to ambulate with powered exoskeleton.
• Measurements of oxygen uptake (VO2) and HR were recorded for 6 min each during each maneuver while sitting, standing, and walking.

Results
• HR and VO2 responses to exoskeletal-assisted walking in persons with motor-complete paraplegia were mildly increased from sitting and standing but well below maximal predicted value for both variables.

Conclusion
• Persons with paraplegia were able to ambulate efficiently using powered exoskeleton for overground ambulation, providing potential for functional gain and improved fitness.
