The purpose of this study is to determine whether supervised progressive resistance training is effective in the early phase after Total Hip Replacement. The investigators hypothesise that 10 weeks of supervised, progressive resistance training immediately after discharge will lead to increased functional performance, muscle strength and muscle power compared to standard rehabilitation consisting of home-based exercise.
After total hip replacement (THR) surgery there is a documented deficit in muscle strength and functional performance. There is a lack of evidence concerning the effectiveness of postoperative physiotherapy and training, however a few small studies have shown promising effect of resistance training. The present study will provide new and important knowledge concerning the effect of different rehabilitation strategies after THR. This might lead to a change in the rehabilitation regimes and faster and better recovery after THR surgery.

Gait quality
Instrumented gait analysis using a combined accelerometer and gyro-sensor in 20 meter walk test and stair climb test. The purpose is to measure asymmetry between limps during walking and stair climbing and compare the two groups according to these variables. This outcome measure is performed on a subgroup of participants (n=26, 13 in each group)
Time frame: 10 weeks postoperative
