Multiple studies on the use of the PSFS with musculoskeletal complaints or COPD reveal that the PSFS has very good reliability, validity, responsiveness to change as well as ability to detect real change.
The PSFS is a potentially useful tool for assessing disability and change in disability for patients with pulmonary or cardiac disease participating in rehabilitation programs.
What is the compliance rate across the School of Physiotherapy Clinics for the collecting of PSFS and NPRS outcomes both at the initial treatment and at discharge?
What is the percentage (or relative) change in pain and function for particular conditions or regions using the PSFS and the NPRS?
The outcome measures used for this study were the PSFS and the NPRS.
Clinic staff and student physiotherapists were asked to administer the PSFS and NPRS to all new patients, at the initial assessment and at discharge, during a three month period (18 March--17 June 2005).
For each complaint, the mean and standard deviation was calculated for; number of patients with complete data, percentage of outcomes completed at initial and discharge, number of treatments received, baseline PSFS and NPRS ratings, discharge PSFS and NPRS ratings, and relative score change in PSFS and NPRS.
Complete baseline and follow-up data was collected on 213 (70%) of these patients for both the PSFS and the NPRS.
Although MCID was not calculated in this study, our data indicate that the majority of our patients experience mean change in the PSFS exceeding the MCID for neck problems (MCID 2 points) (Cleland, Joshua A.
The construct validity, reliability, and responsiveness of the PSFS has been demonstrated for some of the conditions included in our observational cohort (Chatman et al.
It is not known whether using relative change in scores is a more valid way of calculating change than using absolute change in scores for the PSFS or the NPRS.
