Effects of Trunk Control Rehabilitation Robot Training on Dynamic Balance, Lower Extremity Strength, Gait Ability and Pain in Bipolar Hemiarthroplasty

ABSTRACT

PURPOSE: This study examined the effects of trunk control rehabilitation robot training (TCRRT) on the dynamic balance, lower extremity strength, gait ability and pain for bipolar hemiarthroplasty. METHODS: Hemiarthroplasty (n=28) patients participated in this study. The subjects were randomized into two groups trunk control rehabilitation robot training group and control group. RESULTS: The TCRRT group showed significantly more improvement in the MFRT, MMT, 10MWT, TUG, and VAS compared to that before intervention (p<0.05). In addition, all tests were significantly greater in the experimental group than in the control group. CONCLUSION: These results suggest that TCRRT is feasible and effective for improving the dynamic balance, lower extremity strength, gait ability, and pain efficacy after bipolar hemiarthroplasty.
