Introduction: Trigger finger disorder is a sudden release or locking of a finger during flexion or extension. Regarding the complications and disadvantages mentioned for the methods used in the treatment of trigger finger disorder, the aim of this study was to investigate the effect of extracorporeal shock wave therapy in the treatment of patients with trigger finger.
Methods: This study was an interventional study recruiting 19 patients with trigger finger disorder. Evaluation of pain severity, severity of triggering, and functional impact of triggering was carried out using the Visual Analogue Scale, Trigger Finger Score suggested by Quinnell, and Quick-Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, respectively, before intervention, immediately after intervention, and in 6 and 18 weeks after intervention. Each patient was treated with extracorporeal shock wave therapy in three sessions with a 1-week interval. Data were analyzed in Statistical Package for the Social Sciences (SPSS) software using ANOVA to monitor changes in pain severity, severity of triggering, and functional impact of triggering during follow-ups.
Results: There were statistically significant differences with regard to reduction of the pain severity, severity of triggering, and functional impact of triggering before intervention, immediately after intervention, and in 6 and 18weeks after intervention (P< 0.01). However, the effect of extracorporeal shock wave therapy on reducing severity of triggering immediately after intervention did not yield a statistically significant difference compared to before intervention (P> 0.01).
Conclusion: It seems that extracorporeal shock wave therapy leads to a reduction in pain severity, severity of triggering, and functional impact of triggering. These effects persisted until the 18th week after the intervention. It is recommended to use extracorporeal shock wave therapy in terms of a non-invasive intervention with no significant complications for patients with trigger finger.

体外冲击波治疗扳机指患者的疗效

简介：扳机指障碍是指在屈曲或伸展过程中突然松开或锁定手指。关于治疗扳机指障碍的方法中提到的并发症和缺点，本研究的目的是探讨体外冲击波疗法在治疗扳机指患者中的效果。
方法：本研究是一项介入性研究，招募了 19 名扳机指障碍患者。之前，分别使用视觉模拟量表、Quinnell 建议的触发手指评分和手臂、肩部和手部快速残疾 (DASH) 问卷对疼痛严重程度、触发的严重程度和触发的功能影响进行了评估干预，干预后立即，干预后 6 周和 18 周。每位患者均接受 3 次体外冲击波治疗，间隔 1 周。使用 ANOVA 在社会科学统计软件包 (SPSS) 软件中分析数据，以监测随访期间疼痛严重程度、触发严重程度和触发的功能影响的变化。
结果：干预前、干预后即刻、干预后6周和18周疼痛严重程度、触发严重程度和触发对功能影响的降低差异有统计学意义（P < 0.01）。但体外冲击波治疗对降低干预后即刻触发严重程度的影响与干预前相比差异无统计学意义（P > 0.01）。
结论：体外冲击波疗法似乎可以降低疼痛的严重程度、触发的严重程度和触发的功能影响。这些影响一直持续到干预后的第 18 周。对于扳机指患者，推荐使用体外冲击波治疗，无创干预，无明显并发症。
