Spinal Cord Injury Assistive Technology Rehabilitation

Simple Explanation

This study explores the use of a standing power wheelchair for people with spinal cord injury (SCI). The goal was to see if using the wheelchair improved independence, usability, and quality of life. Four participants with chronic SCI used the standing power wheelchair three times a week for 12 weeks. Researchers monitored their safety, blood pressure, and satisfaction with the device. The study found that the standing power wheelchair was safe and effective for the participants. They maintained normal blood pressure and were able to perform mobility tasks independently. Participants also reported improvements in their quality of life.

Study Duration

12 weeks

Participants

Four participants with chronic SCI

Evidence Level

Case Series

Key Findings

1
Participants consistently maintained normal blood pressure responses between seated and standing positions throughout the training sessions.
2
Participants learned to perform all the mobility tasks safely and independently.
3
Participants reported improvements on the SCI-QOL and were generally satisﬁed with the upright standing power wheelchair.

Research Summary

This case series investigated the safety, feasibility, and usability of a standing power wheelchair (UPnRIDE) for individuals with chronic spinal cord injury (SCI). Four participants used the device three times a week for 12 weeks. The study found that participants could independently perform mobility tasks like sit-to-stand and navigate various surfaces while standing. They also tolerated more time standing than sitting and reported overall satisfaction with the device. The use of the standing power wheelchair was beneficial for increasing blood pressure tolerance with changing positions. Some participants also reported improvements in bladder complications, pain interference, and pain behavior.

Practical Implications

Improved Mobility and Independence

The standing wheelchair provides users with a new level of mobility and freedom of upper extremities, and requires less upper body function than current exoskeletons.

Physiological Benefits

Regular use of the standing wheelchair can improve blood pressure tolerance and reduce the risk of orthostatic hypotension in individuals with SCI.

Potential for Enhanced Rehabilitation

The standing position supports stretching of the lower extremities, which is important for maintaining range of motion and preventing contractures.

Study Limitations

1
Small sample size with different levels and completeness of SCI.
2
Training duration varied based on availability and tolerability of the participants.
3
The design of the device’s leg rests presented limitations for participants when transferring in and out of the UPnRIDE wheelchair which required assistance.
