Trigger finger (TF) is a common hand pathology frequently encountered in hand clinics. Occupational therapists predominantly assess TF symptoms as opposed to using standardized hand functioning assessments. The purpose of this study was to assess the construct validity of dexterity and grip strength assessments for clients with TF.
Sixty-three participants with TF and 66 healthy controls were administered the Functional Dexterity Test (FDT), Purdue Pegboard Test (PPT), and Jamar® Hydraulic Hand Dynamometer (JD) and completed the Disabilities of Arm Shoulder and Hand questionnaire (DASH). TF symptoms were graded using the Quinnell classification.
Statistically significant differences were found between the groups in dexterity and grip strength. A statistically significant difference between the three TF grades was found on the PPT. All three test scores were moderately correlated with the DASH scores.
This study provides innovative evidence for the validity of common hand function assessments for individuals with TF and recommends incorporating these tools in clinical practice. Further research is needed with larger samples and better representation of each TF clinical grade.
扳机指（TF）是手部诊所中常见的手部病症。职业治疗师主要评估扳机指症状，而非使用标准化的手部功能评估方法。本研究的目的是评估针对扳机指患者的灵活性和握力评估的结构效度。
对63名扳机指患者和66名健康对照者进行了功能性灵活性测试（FDT）、普渡钉板测试（PPT）和Jamar®液压式握力计（JD）测试，并完成了手臂、肩部和手部功能障碍问卷（DASH）。使用奎内尔分类法对扳机指症状进行分级。
两组在灵活性和握力方面存在统计学上的显著差异。在普渡钉板测试中，三个扳机指等级之间存在统计学上的显著差异。所有三项测试分数均与DASH分数呈中度相关。
本研究为针对扳机指患者的常见手部功能评估的有效性提供了创新性证据，并建议将这些工具纳入临床实践。需要进一步开展更大样本量且能更好地代表每个扳机指临床等级的研究。
