Brief summary

This study is testing the psychometric properties of a new tool to determine recommendations for pressure relief frequency in wheelchair users.

Detailed description

The goal of the proposed study is to establish the content validity and inter-rater reliability of a new tool, the Pressure Relief Frequency Scale (PReFS). Findings from this study will provide clinicians with a tool that can be used to develop an individualized approach to teaching patients how frequently to perform weight shifts. The part of the study will establish the inter-rater reliability of the PReFs through video recordings of individuals who are wheelchair users.
