Pressure Relief Frequency Scale (PReFS) for wheelchair users
Reliability and Validity of the Pressure Relief Frequency Scale
This project tests whether a new Pressure Relief Frequency Scale (PReFS) can reliably guide how often wheelchair users with neurologic disorders should perform weight shifts.

What this trial studies
The project aims to establish content validity and inter-rater reliability for the PReFS, a tool designed to recommend pressure-relief frequency for wheelchair users. Content validity will be explored through interviews with clinicians and stakeholders to ensure the tool covers relevant concepts. Inter-rater reliability will be measured by having clinicians rate video recordings of primary wheelchair users performing weight shifts. The work is observational and focuses on wheelchair users with neurologic diagnoses who use their chair for most of the day.
Who should consider this trial
Good fit: Ideal candidates are adults who are primary wheelchair users with a diagnosed neurologic disorder who use their wheelchair for more than half of their waking hours.
Not a fit: People who are not primary wheelchair users or who use a wheelchair less than 50% of waking hours may not receive direct benefit from this project.
Why it matters
Potential benefit: If successful, clinicians would have a validated tool to tailor pressure-relief teaching and potentially reduce pressure injury risk for wheelchair users.
How similar studies have performed: Similar psychometric studies of seating and pressure-management tools have shown that clinician-rated scales can be reliable, but the PReFS itself is a new tool undergoing initial validation.
