Functional Outcomes After a Physiotherapy Program in Elderly Patients With Complex Regional Pain Syndrome Type I After Distal Radius Fracture: A Prospective Observational Study

Abstract:

Background: No published prospective studies have reported the clinical effects of physiotherapy at 1-year follow-up in patients with complex regional pain syndrome type I (CRPS I) after distal radius fracture (DRF). The purpose of this study was to evaluate at 1-year follow-up the functional effects of physiotherapy program in elderly patients with CRPS I after extra-articular DRF. Methods: A total of 72 patients with CRPS I after DRF were prospectively recruited. All patients were treated with a 6-week supervised physiotherapy treatment. Three evaluations were performed: at the beginning, at the end of the treatment, and at 1-year follow-up. Wrist function, upper limb function, grip strength, and pain intensity were assessed with the Patient-Rated Wrist Evaluation (PRWE), Disabilities of the Arm, Shoulder, and Hand (DASH), Jamar dynamometer, and Visual Analogue Scale (VAS), respectively. Results: At 1-year follow-up, the PRWE showed a decrease of 21.6 points (Cohen’s d = 2.8; 95% confidence interval [CI] = 18.6-24.6; P <.05); the DASH showed a decrease of 23.8 points (Cohen’s d = 2.9; 95% CI = 20.8-26.7; P <.05); grip strength showed an increase of 40.6% (Cohen’s d = 5.0; 95% CI = 43.5-37.6; P <.05); and the VAS showed a decrease of 2.6 cm (Cohen’s d = 1.9; 95% CI = 2.11-3.16; P <.05). Conclusion: At 1-year follow-up, a physiotherapy program showed clinically and statistically significant results in all functional outcomes in elderly patients with CRPS I after extra-articular DRF.
