摘要

Objectives: To determine the efficacy of extracorporeal shockwave therapy (ESWT) and to determine the ideal energy flux density of wide-focused ESWT in the treatment of trigger finger (TF). Design: Double-blind randomized controlled trial. Setting: A university hospital. Participants: A total of 60 patients (N=60) with grade II TF according to the Quinnell classification were randomly and evenly allocated to 3 treatment groups. Interventions: Three treatment groups included a high-energy ESWT (HS) group (energy flux density of 0.01 mJ/mm2, 5.8 bar, 1500 impulses, once per week for 4wk), a low-energy ESWT (LS) group (energy flux density of 0.006 mJ/mm2, 3 bar, 1500 impulses, once per week for 4wk), and a sham intervention group (sham group). All participants received 6 months of follow-up after intervention when only painkillers were allowed as concomitant treatment. Main Outcome Measures: Clinical outcomes were followed at baseline and 1, 3, and 6 months after intervention, including pain score, frequency of triggering, severity of triggering, functional impact of triggering, and quick Disabilities of the Arm, Shoulder, and Hand questionnaire (qDASH). Results: All groups showed significant improvements from baseline in all clinical parameters, except for functional impact of triggering, 6 months after the interventions. However, the HS group demonstrated a higher magnitude of improvement than the LS and sham groups. In addition, the HS group reported significantly lower pain (P=.01) and lower qDASH (P=.008) than the sham group 6 months after the interventions. No adverse effects were reported in the HS and LS groups within 6 months of follow-up. Conclusions: Wide-focused ESWT is a safe and effective but dose-dependent alternative facilitating pain relief and functional improvement in the treatment of grade II TF according to the Quinnell classification.
