RESUMEN
PURPOSE: This study aimed to evaluate the efficacy of hand therapy after volar locking plate fixation of distal radius fractures in middle-aged to elderly women. METHODS: Fifty-seven patients diagnosed with distal radius fractures who had undergone volar plate fixation were enrolled in a prospective, randomized controlled trial. Patients were randomized into the hand therapy and independent exercise (IE) groups, in which they exercised independently under the surgeon's direction with and without hand therapy, respectively. The primary outcome was the functional outcome measured using the Disability of Arm, Shoulder, and Hand questionnaire after 6 weeks. The secondary outcomes were functional outcomes measured using the Patient-Rated Wrist Evaluation questionnaire, active and passive ranges of motion (ROMs), grip strength, key pinch strength, and pain measured on a visual analog scale. Patients were followed up in the outpatient department at 2, 4, 6, and 8 weeks and at 3 and 6 months. RESULTS: The Disability of Arm, Shoulder, and Hand scores were significantly lower in the hand therapy group at 6 weeks after surgery (12.5 vs 19.4 in the IE group). The postoperative visual analog scale pain scores were significantly lower in the hand therapy group at 2, 4, and 6 weeks (10.2 vs 17.6 in the IE group). The active ROM of the wrist flexion-extension arc at 2, 4, 6, and 8 weeks; active ROM of the pronation-supination arc at 6 and 8 weeks; and passive ROM of the wrist flexion-extension arc at 2, 4, and 8 weeks were significantly greater in the hand therapy group. CONCLUSIONS: Hand therapy improved the outcomes after volar locking plate fixation for distal radius fracture in middle-aged to elderly women at 8 weeks after surgery. No significant between-group differences were observed in any functional outcome measure at 6 months after surgery, as previously reported. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.
