Prospective cohort correlation study. There is no
known published research on correlations between the Patient-Specific Functional
Scale (PSFS), hand grip strength, and the Disability of the Arm, Shoulder and
Hand (DASH) in a population with hand osteoarthritis (OA).
The purpose
of this study is to establish reliability of the PSFS and to evaluate the
relationship between the PSFS, hand grip strength, and the
DASH for a population
with hand OA. METHODS: Thirty-five participants in 4 hand clinics completed the
PSFS, hand grip strength testing, and the DASH at the onset of therapy and at
discharge. Eighteen participants enrolled at the primary investigator's site
completed a baseline PSFS one week before the pretreatment collection with data
used to establish relative and absolute reliability. Data were analyzed
separately at pretreatment and posttreatment with Spearman's rho correlation (P <
.05). Intraclass correlation (2, 1), standard error of the measurement, and
minimum detectable change (MDC90 and MDC95) were calculated from the repeated
baseline and pretreatment PSFS. RESULTS: Intraclass correlation for PSFS was (r =
0.80) with the standard error of the measurement = 0.56, MDC90 = 1.30, and MDC95
= 1.56. Small correlation between the PSFS and DASH scores was found pretreatment
(rho = -0.10) and change scores (rho = 0.13). CONCLUSION: Excellent reliability
with small measurement error has established clinical utility of the PSFS for the
population with hand OA. These outcome measures were shown to measure different
constructs and therefore should not be used interchangeably. LEVEL OF EVIDENCE: 3.
