Background: The purpose of this study is to investigate that effect of manual therapy using pelvic compression belt on hip abductor strength and balance ability in total knee replacement (TKR) patients.
Methods: The subjects consisted of twenty two post-TKR patients. Participants were randomly assigned to a pelvic belt group (n=11) and a placebo group (n=11). All participants underwent manual therapy including range of motion exercise, soft tissue mobilization around knee joint, strengthening exercise (Quad set, SLR, sidelying hip abduction, standing hamstring curls, sitting knee extension, step-up, wall slide to 45° knee flexion). Manual therapy was executed five times a week for 2 weeks. Outcome measures included hip abductor strength by using Biodex system 4 pro, anterior to posterior balance, medial to lateral balance, total balance by using Biodex balance system SD.
Results: After the completion of the manual therapy, hip abductor strength was showed statistically significant improvements in pelvic belt group (p<.05). Anterior to posterior balance, medial to lateral balance, total balance were showed statistically significant improvements in pelvic belt group and placebo group (p<.05). There was a statistically significant difference between the two groups in hip abductor strength and there was no statistically significant difference in balance.
Conclusions: This results suggest that manual therapy using pelvic compression belt has could be used for selective muscle activation of the hip abductor muscle and has useful in hip abductor strength and balance ability in TKR patients.
