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), 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=0.97 (95%CI 0.950.99) 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.
