Abstract

The aim was to investigate gait asymmetry and pelvic range of motion during walking and stair ascending after total hip replacement, and secondly to test whether these parameters were influenced by resistance training.

A consecutive sample of 32 patients within a randomized controlled trial (control versus exercise group) was included. Speed, asymmetry and pelvic range of motion (walk and stair test) and leg power were measured preoperative, 10weeks and 6 months postoperative.

Walking and stair ascending speed, leg power and pelvic movements (frontal plane) during walking increased to 6 months follow up (p<0.005). There were no significant changes in gait asymmetry or the remaining pelvic movements (p>0.05) and no between-group differences.

Pelvic movements in the frontal plane during walking increased after surgery. No changes occurred in gait asymmetry and pelvic movements 6 months after total hip replacement while leg power and speed during walking and stair ascending increased significantly.
