Although self-assessment questionnaires for the wrist joint are numerous, most validation studies focus on a specific pathology and patient collectives. In addition the available questionnaires focus on subjective parameters such as pain, usual and specific activities but the range of motion (ROM) as an essential objective parameter in wrist disorders is rarely considered. Therefore the purpose of the presented study was to develop and validate a new universally applicable self-assessment score, the Munich Wrist Questionnaire (MWQ), which allows for the assessment of subjective as well as objective parameters of the wrist joint.
The MWQ consists of 16 items addressing three domains: pain, work and activities of daily living and wrist function including range of motion and grip strength. In a prospective clinical study validity, reliability and responsiveness of the MWQ of physical active patients were evaluated.
Validation study included 100 patients (mean age 41 years, SD 16.3 years; range, 18-77 years). Test-retest reliability was substantial, with intraclass correlation coefficients ranging from 0.75 to 0.83 for the three domains. Construct validity and responsiveness were confirmed by correlation coefficients of at least 0.86 for construct validity and for responsiveness ranging from 0.61 to 0.65.
The MWQ presents a valid and reliable instrument for a qualitative self-assessment of subjective and objective parameters (e.g. range of motion) of the wrist joint. Quantitative measurement of wrist function may not longer be limited to specific wrist disorders or patient groups. The MWQ seems to allow for a broad application in clinical research and may facilitate the comparison of treatment results in wrist disorders.
尽管用于腕关节的自我评估问卷众多，但大多数验证研究都集中在特定的病理学和患者群体上。此外，现有的问卷侧重于疼痛、日常和特定活动等主观参数，而腕关节疾病中作为重要客观参数的活动范围（ROM）却很少被考虑。因此，本研究的目的是开发并验证一种新的通用自我评估评分系统——慕尼黑腕关节问卷（MWQ），该问卷可用于评估腕关节的主观和客观参数。
MWQ由16个项目组成，涉及三个领域：疼痛、工作和日常生活活动以及腕关节功能，包括活动范围和握力。在一项前瞻性临床研究中，对身体活跃患者的MWQ的有效性、可靠性和反应性进行了评估。
验证研究纳入了100名患者（平均年龄41岁，标准差16.3岁；范围为18 - 77岁）。重测信度较高，三个领域的组内相关系数在0.75至0.83之间。结构效度和反应性通过结构效度相关系数至少为0.86以及反应性相关系数在0.61至0.65之间得到证实。
MWQ是一种有效且可靠的工具，可用于对腕关节主观和客观参数（如活动范围）进行定性自我评估。腕关节功能的定量测量可能不再局限于特定的腕关节疾病或患者群体。MWQ似乎可广泛应用于临床研究，并可能有助于比较腕关节疾病的治疗结果。
