Objective : The purposes of this study were to find correlations among Postural Assessment Scale for Stroke, MBI, Tone Assessment Scale, FM-U/E, and to predict MBI, FM-U/E: from subscales of Postural Assessment Scale Stroke.
Methods : The subjects were 41 stoke patients of the Korea national Rehabilitation Center in Seoul. All patients were assessed on Postural control was measured with the use of the Postural Assessment Scale Stroke, ADL(by the Modified Barthel Index), Tone(by the Tone Assessment Scale), performance function of U/E(by the Fugl-Meyer assessment), The data were analyzed using Pearson product correlation. Postural Assessment Scale for Stroke(PASS)scale between other clinical and instrumental index, multiple stepwise regression analyses were performed to identify prognostic factors for ADL incline, Cronbach’s alpha coefficient to identify Internal Consistency on PASS scale.
Results : The highest level was standng with support, the lowest level was standing on paretic leg on PASS scale. The highest level was chair/bed transfer, the lowest level was bathing on MBI. All items of the Postural Assessment Scale, were significantly correlated with MBI, FM-U/E, TAS(r=-.33~.91 p<.05~,01). There were significant correlations between MBI-U/E and MBI(r=.35, p<.05), TAS-rest(r=-.40, p<.01), TAS-asso(r=-.39, p<.05). The Internal Consistency (Cronbach a=0.86) was very high, indicating that the PASS is homogeneous and is likely to produce consistent response. Furthermore, the sums of maintaining position items and of changing-position items were strongly correlated(r=.69, p<.01) and there were significant correlations between sums of PASS and sums of maintaining position items(r=.90, p<.01), changing-position items(r=.93, p<.01). The Supine to nonaffected side lateral and Standng picking up a pencil from the floor of PASS items was the strongest variance(R2=.95, R2=.56) of the predicting ADL function, performance of function U/E.
Conclusion : The PASS is suited to the assessment of postural control abilities, it demonstrated an acceptable for the evaluation of functional recovery of stroke patients in clinical practices.
