Progressive strength training in older patients after hip fracture : a randomised controlled trial

摘要

Objective: the aim of this study was to assess the effect of a 3-month strength-training programme on functional performanceand self-rated health in a group of home-dwelling older hip fracture patients.Design: randomised, controlled; single-blind parallel-group trial.Setting: intervention at outpatient’s clinic.Subjects: one hundred and fifty patients with surgical fixation for a hip fracture.Methods: strength training was integrated into all stages of the programme. The programme comprised four exercises, halfof them in a standing position, performed at 80% of maximum. Measurements were taken after the 3-month intervention.The primary outcome measurement was the Berg Balance Scale (BBS). Secondary outcomes were results of the sit-to-standtest, Timed Up-and-Go test, maximal gait speed, 6-min walk test, Nottingham Extended Activities of Daily Living scaleand the SF-12 health status questionnaire.Results: at baseline, there were no significant between-group differences. At follow-up, the intervention group showedhighly significant improvements both in the primary endpoint (BBS, mean difference 4.7 points) and in secondary endpointsof tapping strength, mobility and instrumental activities of daily living.Conclusion: home-dwelling hip fracture patients can benefit from an extended supervised strength-training programme ina rehabilitation setting. These patients are capable of high-intensity strength training, which should optimise gains in physicalfunction, strength and balance. Resistance exercise training seems to influence functional performance adaptation.
