For standing balance, the subjects were given a score of 0-3 as described in the method. For the 6-m usual walk test and repeated chair stands, quartiles based on the performance of the study subjects were created.
Zero represents the worst and 3 represents the best performance. Values are the number (%). Distribution of categories between non-OA and OA was compared with Chi-square test.
