Effects of Real-Time Pressure Map Feedback on Confidence in Pressure Management in Wheelchair Users With Spinal Cord Injury: Pilot Intervention Study.

Tamara L Vos-Draper, Melissa M B Morrow, John E Ferguson and 1 others

PMID 37824188

WHAT IT FOUND

Real-time pressure feedback significantly improved wheelchair users' confidence in knowing how far to lean to relieve pressure.

It did not improve confidence in performing weight shifts frequently or for long enough. Standard education alone also increased confidence in preventing skin breakdown.

Key findings

01Confidence in knowing how far to move to effectively redistribute pressure increased significantly after using real-time pressure mapping feedback.

02Confidence in performing weight shifts at the recommended frequency and duration did not change significantly with feedback.

03Standard patient education alone significantly increased confidence that weight shifts prevent pressure injuries.

What it does not show

The study was a pilot with a small sample size of 23 participants, limiting generalizability. The home phase lasted only one month, so long-term effects on confidence or behavior are unknown. The study measured confidence (self-efficacy), not actual weight shift behavior or pressure injury incidence. The system lacked reminders or alarms, which may explain why frequency and duration confidence did not improve.

The easy way to misread this

Do not interpret improved confidence scores as evidence that the intervention prevents pressure injuries or changes actual weight shift behavior. The study only measured self-reported confidence, and no clinical outcomes like skin breakdown were tracked.
