Early Rehabilitation After Total Hip Replacement

Not Applicable

Completed

• Conditions: Osteoarthritis, Hip
• Interventions: Other: Control group; Other: Supervised progressive resistance training

• Registration Number: NCT01214954
• Lead Sponsor: University of Aarhus

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.

Arm && Interventions

Group	Intervention	Description
Control group	Control group	Standard rehabilitation
Resistance training	Supervised progressive resistance training	10 weeks of supervised progressive resistance training initiated within the first week after total hip replacement.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
Walking speed	6 months postoperative	Maximal walking speed measured over 20 m.
Sit-to-stand	6 months postoperative	The maximal number of rises from a chair within 30 seconds
Stair test	6 months postoperative	The time taken to ascend 18 steps as fast as possible
Hip Osteoarthritis Outcome Score (HOOS)	1 year postoperative	Questionnaire. A disease-specific patient reported outcome measure of function, pain, sport/recreation and quality of life related to the hip.
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)
Isometric muscle strength	6 months postoperative	Test of isometric muscle strength in hip abduction and hip flexion using hand-held dynamometry
Gait quality	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)
