Objective:
Fewer than half of the patients with hip fracture will regain the prefracture level of physical functioning. This secondary analysis of a randomized controlled trial investigated the effects of a multicomponent home-based rehabilitation program (ProMo) on physical disability after hip fracture.
Design:
Randomized, controlled, parallel-group trial.
Setting:
Rehabilitation in participants' homes; measurements in university-based laboratory and local hospital.
Participants:
Population-based clinical sample of community-dwelling people older than 60 years (n = 81) operated for hip fracture were randomized into intervention and control groups.
Intervention:
The year-long intervention aimed at restoring mobility. It included evaluation and modification of environmental hazards, guidance for safe walking, pain management, home exercise, physical activity counseling, and standard care.
Measurements:
Physical disability was assessed by a questionnaire at baseline, and 3, 6, and 12 months thereafter. Sum scores were computed for basic (ADLs) and instrumental activities of daily living (IADLs). A higher score indicated more difficulty. GEE models were constructed to analyze the effect of the intervention.
Results:
In the intention-to-treat analysis, no intervention effect was observed for sum scores. For the single disability items, borderline significant positive effects were observed for preparing food and handling medication (interaction P = .061 and P = .061, respectively). In the per-protocol analysis, the mean differences between groups were -0.4 points (SE 0.5), -1.7 (0.7), and -1.2 (0.7) at 3, 6, and 12 months for ADLs and -1.0 (1.2), -3.2 (1.5), and -2.5 (1.4) for IADLs, correspondingly.
Conclusion:
The current analyses suggest that home-based rehabilitation may reduce disability among older people after hip fracture. The present results need to be confirmed in a study with larger sample size. Potentially a more task-oriented rehabilitation approach might gain more benefits. Current Controlled Trials (ISRCTN53680197).
