Abstract

Purpose: The purpose of this study was to determine reliability and validity of the Postural Assessment Scale for Stroke Patients (PASS) in chronic stroke patients. Methods: A total of 43 stroke patients, who had a stroke more than 6 months previously, participated in the study. Reliability was determined by the intra-class correlation coefficient (ICC$_{3,1}$), Bland and Altman method and Cronbach's alpha by internal consistency. Validity was examined by correlation the PASS scores to the Berg Balance Scale (BBS), Trunk Control Test (TCT), and Fugl-Meyer Balance (FM-B) score. Results: The intra-rater reliability and the Absolute reliability of the PASS was good ICC$_{3,1}$=0.97 (95%CI 0.95$\sim$0.99) and excellent SEM=1.01 respectively. Cronbach's alpha value for PASS was found to be 0.94. There were significant correlations between the PASS and BBS, TCT, FM-B (r=0.65－0.96, p<0.01). Conclusion: The PASS provide reliable and valid instrument of the postural control assessment for chronic stroke patients.
