      Extracorporeal shockwave therapy in the treatment of trigger finger: a randomized controlled study.
      titled “Extracorporeal Shockwave Therapy in the Treatment of Trigger Finger: A Randomized Controlled Study” with great interest. The study demonstrated that among 3 groups, no significant differences in clinical parameters were observed at the first and third months after the intervention. The only significant differences observed were lower pain and Quick Disabilities of the Arm, Shoulder, and Hand scores in the high-energy ESWT group (HS group) than in the sham group at the 6-month follow-up. Although the authors explained that the lack of differences at the 1- and 3-month evaluations may have been because of the small sample size, the results cannot convince readers that the effect of the intervention in the HS group was stronger than that in the other 2 groups.
