Study Overview
Brief Summary
Trigger finger is the common name of stenosing tenosynovitis of fingers, caused by repetitive trauma. Conservative treatment includes NSAIDs or other analgesic agents, activity modification, splint, and physiotherapy. Operation could be considered if conservative treatments fails. With literature reviewed, there is no treatment which is both non-invasive and effective, and also could avoid recurrence well.
Extracorporeal shock wave therapy could induce angiogenesis, anti-inflammatory reaction, and recruitment of fibroblast. Although extracorporeal shock wave has been utilized in musculoskeletal diseases for more than twenty years, there is no well-designed clinical trial to prove the effectiveness of extracorporeal shock wave in treating trigger finger. The purpose of this study is to compare the effectiveness of extracorporeal shock wave therapy with traditional physical therapy for the management of trigger finger.

Outcomes
Primary Outcomes
Chinese quick DASH (disabilities of the Arm, Shoulder, and Hand questionnaire)
Time Frame: 15 weeks
This questionnaire is a self-administered region-specific outcome instrument developed as a measure of self-rated upper-extremity disability and symptoms. The investigators chose the first two components: the disability and symptom section (11 items, scored 1-5). The lower score means better condition of upper limbs, and vice versa.
11-point numeric scale of pain
Time Frame: 15 weeks
The 11-point numeric scale of pain requires the patient to rate their pain on a defined scale. 0 is no pain and 10 is the worst pain imaginable.
Quinnell stages of triggering
Time Frame: 15 weeks
Quinnell stages of triggering classifies the trigger finger using five types during flexion and extension: normal movement (Type 0), uneven movement (Type I), actively correctable (Type II), passively correctable (Type III) and fixed deformity (Type IV).
sonographic image
Time Frame: 15 weeks
The investigators would record the characteristics of acquired sonographic images, such like the thickness of finger flexor tendon and A1 pulley, the presence of tendon sheath effusion, and the presence of increased vascularity by Doppler images.
strength of hand grip
Time Frame: 15 weeks
The strength of hand grip is to measure the maximum isometric strength of the hand and forearm muscles by a electicial grip strength device.
Secondary Outcomes
No secondary outcomes reported
