Objectives:
To investigate the long-term effects of Extracorporeal shockwave therapy (ESWT) and ultrasound (US) in treating the trigger finger. Trigger finger, also known as stenosing tenosynovitis, is a common type of tenosynovitis affecting the flexor sheath of any finger. Extracorporeal shockwave therapy and therapeutic US are conservative treatments that use waves of varied frequency to target damaged regions and improve function.
Methods:
This cohort study was carried out in Saudi Arabia, using samples obtain from the files of patients with trigger fingers who visited the orthopedic department at Al-Rass General Hospital between May and June 2023. Of the 38 people with trigger fingers who were initially included, 24 satisfied the requirements for inclusion (11 underwent US, and 13 received ESWT). Assessments were conducted in September 2023, two months later. A goniometer was used to measure the range of motion (ROM), an electrical dynamometer was used to test grip strength, a numerical pain rating scale was used to quantify discomfort, and QuickDASH was used to measure general functional capacity.
Results:
Extracorporeal shockwave therapy and US significantly affected all outcomes, including pain severity, ROM, hand strength, and general functional capability (p<0.005). In the immediate period, the US outperformed ESWT in enhancing general functional capability. Over time, ESWT was more essential for reducing pain (p=0.001).
Conclusion:
This study provides preliminary evidence that ESWT and US have similar effects in treating trigger fingers.
