Spinal Cord Injury Assistive Technology Rehabilitation

Simple Explanation

Wheelchair users with spinal cord injuries are prone to pressure injuries due to impaired sensation and prolonged sitting. This study explores whether real-time pressure mapping feedback can improve their confidence in performing weight shifts to prevent these injuries. The study involved providing participants with standard education on pressure injury prevention and access to a mobile app that displays real-time pressure maps. Researchers then assessed their confidence levels related to performing effective weight shifts. The results showed that access to real-time pressure mapping feedback significantly improved participants' confidence in their ability to move far enough to relieve pressure at high-risk areas.

Study Duration

1 month

Participants

23 adults with SCI

Evidence Level

Not specified

Key Findings

1
Access to live pressure map feedback significantly improved confidence about moving far enough to relieve pressure at high-risk areas.
2
Standard education was most effective in increasing confidence that performing weight shifts reduces pressure injury risk.
3
Confidence in adhering to recommended weight shift frequency and duration was not significantly affected by the interventions.

Research Summary

This study investigated the impact of real-time pressure map feedback on the confidence of wheelchair users with spinal cord injury in performing pressure management techniques. The results showed that access to live pressure mapping feedback improved confidence in performing effective weight shifts to relieve pressure, especially regarding moving far enough to redistribute pressure. The study suggests that continuous or on-demand access to pressure mapping feedback may be a valuable compensatory strategy for improving awareness and confidence in managing pressure for this population.

Practical Implications

Clinical Practice

The 4-item self-efficacy scale can be used to identify areas where wheelchair users feel least confident in their weight shift performance, allowing for targeted interventions.

Technology Development

Future pressure mapping systems should incorporate reminders and alerts for high pressure to improve weight shift timing and adherence.

Further Research

Clinical efficacy studies are needed to explore the impact of these technologies on pressure injury incidence over time.

Study Limitations

1
Lack of data on how frequently participants used the pressure map feedback at home.
2
The weight shift protocol used a qualitative approach to guide participants.
3
Small and heterogeneous sample size.
