Mean WBA (operated side), mean WBA (non-operated side), TTL, and ODA. The measurement methods and instructions were the same as those for mean WBR measurements.OLS test (3-m TUG test. Data were collected as previously described by BBS. To evaluate balance ability, we used a BBS consisting of 14 ADL items. Each item was given a score of 0–4 points, for a total score of 56 points.
