Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the current study is to investigate the effects of powered exoskeleton (EKSO) on cardiovascular performance as measured by resting blood pressure and heart rate, peak oxygen consumption during walking, energy expenditure, whole and regional body composition assessments. The effects of exoskeleton training on walking kinematics including stand-up time, walking time, distance covered and speed of walking will also be evaluated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Powered exoskeletons using robotic suits have recently been introduced for the rehabilitation of persons with spinal cord injury (SCI). Exoskeletons offer a unique opportunity for persons with SCI to experience standing and walking at a low metabolic cost. Evidence suggested that exoskeleton assisted walking can decrease spasticity and improve bowel movement. Training may also improve the level of physical activity as well as psychological parameters that are likely to interfere with rehabilitation outcomes. Previous studies reported that a frequency of 2-3 times per week or more for 1-2 hours may be beneficial in the rehabilitation of persons with SCI. Using exoskeletal-assisted walking to improve the level of physical activity may be appealing to persons with SCI.

Exoskeleton training for 12 weeks may enhance energy expenditure, parameters of physical activity and result only on modest effects on both cardiovascular and body composition parameters. In other words, persons with tetraplegia may have greater cardiovascular and body composition adaptations compared to persons with paraplegia. Twenty subjects will participate in a powered exoskeleton (EKSO) for one or twice a week for 12 weeks. The program will involve walking with the robotic suits for 1 hour for persons with complete (n=10) and persons with incomplete (n=10) SCI.
