Spinal Cord Injury Assistive Technology Rehabilitation

Simple Explanation

This study explores the experiences of people with spinal cord injuries (SCI) as they trained to use the ReWalk exoskeleton. Researchers interviewed participants before, during, and after a 12-week training program to understand their expectations, how they learned, and the changes they experienced. The study found that the exoskeleton allowed participants to perform everyday activities that they were previously unable to do, such as standing to look people in the eye. Participants felt the exoskeleton helped them be "like everyone else." The researchers also explored how users felt about contributing to the research and providing feedback on the exoskeleton's design. This information can be used to improve the design and usability of future exoskeletons.

Study Duration

12 weeks

Participants

11 participants with spinal cord injury

Evidence Level

Not specified

Key Findings

1
The exoskeleton allowed participants to engage in everyday activities, providing a sense of normalcy.
2
Participants experienced both physical and emotional changes during training, including decreased spasticity and improved mental well-being.
3
Participants were motivated to contribute to research and provide feedback to improve exoskeleton design and usability.

Research Summary

This qualitative study explored the experiences of individuals with spinal cord injury (SCI) who underwent training with the ReWalk exoskeleton. The study used interviews to gather data on participants' expectations, learning processes, perceived changes, and contributions to research. The primary theme identified was the desire to be "like everyone else," with participants valuing the ability to perform everyday activities such as walking outside and standing at eye level with others. Training led to physical benefits like reduced spasticity and improved bowel function, as well as enhanced mental well-being through social interaction and a sense of purpose. Participants emphasized their desire to contribute to the development of exoskeleton technology, providing feedback on usability and expressing a willingness to participate in research to benefit others. The study highlights the importance of incorporating user perspectives in the design and implementation of exoskeletons for individuals with SCI.

Practical Implications

User-centered Design

Incorporate user feedback into the design and refinement of exoskeletons to ensure they meet the needs and preferences of individuals with SCI.

Community Accessibility

Increase the availability of exoskeletons in community settings to provide individuals with SCI opportunities to practice and benefit from exoskeleton-assisted walking.

Holistic Benefits

Recognize and address the physical, emotional, and social benefits of exoskeleton training, not just the restoration of walking.

Study Limitations

1
The sample primarily consisted of unemployed individuals, potentially influencing the emphasis on purpose and contribution.
2
Participants were volunteers, limiting the representation of perspectives from those unable or unwilling to commit the time.
3
Audio files and transcripts are not available for review because of the risk of participant identification.
