Brief summary
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.
Detailed description
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.
Interventions
Resistance training 2 times/week initiated within the first week after total hip replacement. The training is supervised by physiotherapists and individually progressed.
OTHERControl group
Standard rehabilitation consisting of home-based exercises with 2 postoperative instructions by a physiotherapist.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Leg extension power | 10 weeks postoperative | The power in leg extension is measured using the Nottingham leg extension power rig. Data is provided in watt and adjusted for bodyweight (watt/kg) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Sit-to-stand | 10 weeks postoperative | The maximal number of rises from a chair within 30 seconds |
| Stair test | 10 weeks postoperative | The time taken to ascend 18 steps as fast as possible |
| Hip Osteoarthritis Outcome Score (HOOS) | 6 months postoperative | Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip. |
| Walking speed | 4 weeks postoperative | Maximal walking speed measured over 20 m. |
| Isometric muscle strength | 4 weeks postoperative | Test of isometric muscle strength in hip abduction and hip flexion using hand-held dynamometry |
| Gait quality | 10 weeks postoperative | 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) |
| Leg extension power | 6 months postoperative | The power in leg extension is measured using the Nottingham leg extension power rig. Data is provided in watt and adjusted for bodyweight (watt/kg) |
