| contents | <p><span><em>Purpose </em></span><em>To investigate the effects of including balance training in a preoperative strengthening intervention on balance and </em><em>functional outcomes in patients undergoing total knee replacement (TKR) and compare these effects to those induced by </em><em>preoperative strengthening and no intervention.</em></p> <p><span><em>Methods </em></span><em>Eighty-two subjects scheduled for TKR were randomly allocated into the strengthening (ST, n = 28) group: a </em><em>preoperative lower limb strengthening intervention; the strengthening + balance (ST + B, n = 28) group: same intervention </em><em>augmented with balance training; and the control group (n = 26). The Berg Balance Scale (BBS) and the function in daily </em><em>living subscale of the Knee Injury and Osteoarthritis Outcome Score (KOOS-ADL) were the primary outcomes. The secondary </em><em>measures included balance and mobility, self-reported status, and knee function. The outcomes were assessed at </em><em>baseline, 1 week before surgery, and 2, (primary endpoint), 6 and 52 weeks after surgery.</em></p> <p><span><em>Results </em></span><em>Compared with the controls, the participants in the ST and ST + B groups presented significant improvements from </em><em>baseline to the end of the preoperative intervention in BBS (p = 0.005) and KOOS-ADL (p < 0.001).
