本文提出了一项前瞻性的纵向研究，以确定DASH、Levine和Kamath问卷的改变分界值，以区分腕管手术后的临床改善。对54例神经传导检查阳性的患者进行前瞻性随访。三份问卷(Dash、Levine和Kamath)分别在患者手术前4周和2周以及术后6周被张贴给患者。完成了患者总体变化印象(PGIC)评分，以评估他们症状的总体变化。根据PGIC的数据，93%的患者有所改善。在腕管松解后，最能确定临床显著改善的原始变化分数的截断值分别为DASH 20.9，Levine 0.47，Kamath问卷1.97。这项研究为确定治疗后临床上有意义的变化提供了方法学框架。现在可以使用所提供的数据对患者进行问卷调查。
This article presents a prospective longitudinal study to determine the cut-off values for change scores of DASH, Levine, and Kamath questionnaires to distinguish clinical improvement following carpal tunnel surgery. Fifty-four patients (40 female, 14 male), with positive nerve conduction studies, were prospectively followed up. Three questionnaires (DASH, Levine, and Kamath) were posted to patients at four and two weeks prior to their operation and then six weeks following surgery. A patient global impression of change (PGIC) score was completed for patients to rate the overall change in their symptoms. According to the PGIC, 93% of patients improved. The cut-off values for raw change scores that best define clinically significant improvement following carpal tunnel release were 20.9 for DASH, 0.47 for Levine, and 1.97 for the Kamath questionnaire. This study provides a methodological framework for identifying clinically significant changes following treatment. A questionnaire follow-up of patients is now possible using the data provided.
