About

People with higher level of spinal cord injury have limitations to using exoskeletal-assisted walking devices due to restrictions of trunk stability, functional use of the upper extremities and hand grip. With increasing sedentary time in wheelchairs, people with SCI have a high risk for developing secondary complications. A powered wheelchair has recently been developed for use in persons with spinal cord injury that provides a solution for placing the user in an upright, standing position while maintaining the overground mobility features of the powered wheelchair; providing the ability to engage in society in either a standing or seated position. The purpose of this study is to verify user performances of the upright powered wheelchair and to identify obstacles that are difficult, or prevent use. Additionally, the option to have upright posture throughout the day may have the potential to improve some of the secondary medical conditions associated with the extreme sedentary lifestyle.

This study will determine change from baseline after 12 weeks of use for safety, tolerance, medical, physical and quality of life outcomes. The intervention will consist of 3.5 hours per session, 3 times per week for 12 weeks. During each session, participants will be asked to stand at least 5 minutes during every 15 minutes. To our knowledge, there is no existing empirical data on intermittent standing during the day in persons with higher levels of SCI who cannot otherwise stand and whether this approach will improve health related outcomes.

UPnRIDE Training

Experimental group

Description:

During each session, heart rate (HR), blood pressure (BP), total session time, time in standing posture, count of sit-to-stand positioning, total distance of overground movement, and rating of perceived exertion (Borg scale) for mobility skills will be monitored. At all study visits during the training period, participants will be asked to answer general health questions about the occurrence of any pressure ulcers or infections.
