Spinal Cord Injury Assistive Technology Rehabilitation

Simple Explanation

Powered exoskeletons offer a way for individuals with spinal cord injuries (SCI) to walk, provided they have good upper body strength and balance. Users need to learn how to balance while standing, sitting, and shifting their weight. This article explains a screening process and training program used at the James J. Peters VA Medical Center to help people with SCI learn to use these devices at the hospital, at home or in the community. The training involves fitting the device, practicing balance, and learning to walk on different surfaces. Companion-walkers are trained alongside the user for home and community use.

Study Duration

Not specified

Participants

12 participants with varying levels of spinal cord injury

Evidence Level

Not specified

Key Findings

1
Participants demonstrated varying initial abilities and improvement rates in using the powered exoskeleton.
2
Walking speed improvements averaged 0.0048 m/sec per session.
3
The 10-meter walk test (10MWT) indicates the best speed the user can achieve, while the 6-minute walk test (6MWT) reflects walking consistency.

Research Summary

The article details a training program for persons with SCI to ambulate using powered exoskeletons, including screening criteria, fitting procedures, and progressive training exercises. Key components of the training involve balance exercises, weight shifting, and walking on varied surfaces, with the goal of achieving independent use of the device in different environments. Assessments such as the 6MWT, 10MWT, and TUG are used to measure progress, with results indicating improvements in walking speed and consistency with training.

Practical Implications

Standardized Training

A standardized training program ensures participant safety, successful device use, and consistent outcomes.

Environmental Adaptation

Training should incorporate varied surfaces and environments to prepare users for real-world ambulation challenges.

Potential for Improved Health

Regular exoskeleton-assisted walking may improve fitness, body composition, and lipid profiles.

Study Limitations

1
The training program was developed for a specific exoskeleton device, limiting generalizability.
2
Low bone mineral density in persons with SCI poses a risk of fractures.
3
The study does not specify the long-term effects of exoskeleton use.
