Effectiveness of supervised physiotherapy versus a home exercise program in patients with distal radius fracture: a randomized controlled trial with a 2-year follow-up

Abstract

Objective To determine in the long term whether supervised physiotherapy is more effective than a home exercise program for functional improvement and pain relief in patients with distal radius fracture (DRF). Design Randomized controlled trial. Setting Rehabilitation hospital. Participants A total of 74 patients older than 60 years with extra -articular DRF were randomly allocated into two groups. Interventions The experimental group received 6 weeks of supervised physiotherapy ( n = 37) and the control group received 6 weeks of home exercise program ( n = 37). Main outcome measures The primary outcome was wrist/hand function assessed using the Patient -Rated Wrist Evaluation (PRWE) questionnaire; secondary outcomes were the pain visual analogue scale (VAS), grip strength and wrist flexion-extension active range of motion. Results All patients completed the trial. For the primary outcome, at 6 -weeks and 1 -year follow-up, the PRWE questionnaire showed a mean difference between groups of 18.6 (95% CI 12.8 to 24.3) and 18.5 points (95% CI 12.7 to 24.2) respectively, these differences are clinically important. Conversely, at 2 -year follow-up this effect decreases to 3.3 points (95% CI -2.4 to 9.0). For secondary outcomes, at 6weeks and 1 -year follow-up, in all measurements the effect size range from medium to large. Conversely, at 2 -year follow-up only grip strength showed large effect size in favor of supervised physiotherapy, the rest of outcomes did not show difference between groups. Conclusion At the 6 -week and 1 -year follow-up, supervised physiotherapy was more effective for functional improvement and pain relief compared with a home exercise program in patients older than 60 years with extra -articular DRF. However, this effect decreases over time, at the 2 -year follow-up, only grip strength showed a difference in favor of supervised physiotherapy.
