Introduction[edit | edit source]
The Patient-Specific Functional Scale (PSFS) is a self-reported, patient-specific measure, designed to assess functional change, primarily in patients presenting with musculoskeletal disorders[1] The scale was developed by Stratford and colleagues70 as a self-report measure of function that could be used in patients with varying levels of independence[1]

- Joint Replacement
- Knee Dysfunction
- Low back pain

Description[edit | edit source]
Patients are asked to identify up to five important activities they are unable to perform or are having difficulty with as a result of their problem. In addition to identifying the activities, patients are asked to rate, on an 11-point scale, the current level of difficulty associated with each activity.Following the intervention, patients are again asked to rate the activities previously identified and are given the chance to nominate new problematic activities that might have arisen during that time.[3] In the 11 point scale
- "0" represents “unable to perform”
- "10" represents “able to perform at prior level”
Patients select a value that best describes their current level of ability on each activity assessed.
Evidence[edit | edit source]
Reliability[edit | edit source]
The reliability of any outcome measure is assessed by the consistent scores it produces on multiple testing, with high test-retest reliability indicating that, when repeated under the same conditions, the measure is likely to yield the same results. For PSFS various authors have calculated the test-retest reliability using Intraclass correlation coefficient (ICC), which gives a score between 0 and 1 for the outcome measure being assessed. The closer the score is to 1, the more reliable the outcome measure. [4]
