比較中風病患姿勢評估量表及短版於復健住院者之反應性

Responsiveness is the ability of measures to detect people’s change, which is necessary for outcome measures. The Postural Assessment Scale for Stroke Patients (PASS) and Short-Form PASS (SFPASS) were developed for stroke patients with sound psychometric properties, which have a potential for routine clinical assessments. A previous study has examined the group-level and individual-level responsiveness of the PASS/SFPASS in patients at 14 days after stroke. However, the individual-level responsiveness of the PASS/SFPASS was unclear. Thus, the purpose was cross-validation of the group- and individual-level responsiveness of the PASS and SFPASS in inpatients receiving rehabilitation. A total of 397 participants were recruited. The PASS was assessed within one week after admission and before discharge from the rehabilitation ward, and the SFPASS was derived from PASS. Group-level responsiveness was examined using paired t-test, Kazis’ effect size, and standardized response mean (SRM). Individual-level responsiveness was examined through the proportion of people whose change in balance function was larger than minimal detectable change. Mean differences of the PASS and SFPASS between pre- and post-test were significant (p ＜ .001). Both measures had similar effect size (Kazis’ effect size: 0.74 and 0.70; SRM: 1.09 and 1.00). The PASS is more sensitive at detecting people’s change (63.0 %; 53%), and the difference was significant (p ＜ .001). PASS had better individual-level responsiveness than SFPASS while the group-level responsiveness was similar. We suggest that the PASS is better for detecting the change of balance function for individual, while SFPASS is more efficiency for group change.
