Study Description
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.

Condition or disease Intervention/treatment
Osteoarthritis, Hip Other: Supervised progressive resistance training Other: Control group

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.

Arms and Interventions

Arm Intervention/treatment
Active Comparator: Control group
Standard rehabilitation
Other: Control group
Standard rehabilitation consisting of home-based exercises with 2 postoperative instructions by a physiotherapist.
Experimental: Resistance training
10 weeks of supervised progressive resistance training initiated within the first week after total hip replacement.
Other: Supervised progressive resistance training
Resistance training 2 times/week initiated within the first week after total hip replacement. The training is supervised by physiotherapists and individually progressed.


Outcome Measures

Primary Outcome Measures :
  1. Leg extension power [ Time Frame: 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 Outcome Measures :
  1. Walking speed [ Time Frame: 4 weeks postoperative ]
    Maximal walking speed measured over 20 m.

  2. Sit-to-stand [ Time Frame: 10 weeks postoperative ]
    The maximal number of rises from a chair within 30 seconds

  3. Stair test [ Time Frame: 10 weeks postoperative ]
    The time taken to ascend 18 steps as fast as possible

  4. Hip Osteoarthritis Outcome Score (HOOS) [ Time Frame: 6 months postoperative ]
    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  5. Walking speed [ Time Frame: 10 weeks ]
    Maximal walking speed measured over 20 m.

  6. Walking speed [ Time Frame: 6 months postoperative ]
    Maximal walking speed measured over 20 m.

  7. Leg extension power [ Time Frame: 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)

  8. Sit-to-stand [ Time Frame: 6 months postoperative ]
    The maximal number of rises from a chair within 30 seconds

  9. Stair test [ Time Frame: 6 months postoperative ]
    The time taken to ascend 18 steps as fast as possible

  10. Hip Osteoarthritis Outcome Score (HOOS) [ Time Frame: 2 weeks postoperative ]
    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  11. Hip Osteoarthritis Outcome Score (HOOS) [ Time Frame: 4 weeks postoperative ]
    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  12. Hip Osteoarthritis Outcome Score (HOOS) [ Time Frame: 6 weeks postoperative ]
    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  13. Isometric muscle strength [ Time Frame: 4 weeks postoperative ]
    Test of isometric muscle strength in hip abduction and hip flexion using hand-held dynamometry

  14. Isometric muscle strength [ Time Frame: 10 weeks postoperative ]
    Test of isometric muscle strength in hip abduction and hip flexion using hand-held dynamometry

  15. Isometric muscle strength [ Time Frame: 6 months postoperative ]
    Test of isometric muscle strength in hip abduction and hip flexion using hand-held dynamometry

  16. Gait quality [ Time Frame: 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)

  17. Gait quality [ Time Frame: 6 months 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)

  18. Hip Osteoarthritis Outcome Score (HOOS) [ Time Frame: 10 weeks postoperative ]
    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.

  19. Hip Osteoarthritis Outcome Score (HOOS) [ Time Frame: 1 year postoperative ]
    Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.
