Katakori is a Japanese term for non-specific symptoms including discomfort or dull pain caused by muscle stiffness around the neck through the shoulders and is one of the most frequently reported symptoms in Japan. However, there has been no standardized patient-reported outcome measure to evaluate Katakori severity. This study aimed to investigate the reporting level on validity and reliability of patient-reported outcome measures of Katakori severity.
A systematic search in ICHUSHI, MEDLINE, EMBASE and PubMed was undertaken from inception to April 2017 without language limitations. Two authors independently undertook screening by inspecting the title and abstract. Inclusion criteria were as follows: (1) participants with Katakori symptoms, (2) reporting reliability or validity of questionnaire evaluating Katakori severity and (3) published journal articles. Studies that either of the authors retained through the screening process were inspected with full text by the two authors independently to examine eligibility of the study. Any disagreement on eligibility after full-text inspection was resolved by discussion between them. Methodological quality was rated with the COnsensus-based Standards for the selection of health Measurement INstruments checklist. Subsequently, the evidence level of each measurement property was assessed for each questionnaire. The two authors extracted data independently. Any disagreement was resolved by discussion between them.
Five questionnaires were identified in five studies. The Shoulder Pain and Disability Index and Scale for Measuring Felt Shoulder Stiffness had the highest level of methodological quality. However, excellent measurement properties were found in only two out of nine criteria. Furthermore, in particular, content validity was not investigated in any measure.
There is preliminary evidence for the reliability and validity of the Shoulder Pain and Disability Index and Scale for Measuring Felt Shoulder Stiffness; however, much further research is required. Identifying or developing a patient-reported outcome measure with content validity would be a future research agenda.
“肩凝症”是一个日语术语，指包括颈部至肩部周围肌肉僵硬所引起的不适或隐痛在内的非特异性症状，是日本最常报告的症状之一。然而，尚无用于评估肩凝症严重程度的标准化患者报告结局指标。本研究旨在调查肩凝症严重程度患者报告结局指标有效性和可靠性的报告水平。
在ICHUSHI、MEDLINE、EMBASE和PubMed数据库中进行系统检索，检索时间从建库至2017年4月，无语言限制。两名作者通过检查标题和摘要独立进行筛选。纳入标准如下：（1）有肩凝症症状的参与者；（2）报告评估肩凝症严重程度问卷的可靠性或有效性；（3）已发表的期刊文章。两名作者对筛选过程中保留的任何研究进行全文检查，以检查研究的合格性。全文检查后在合格性方面的任何分歧通过两人讨论解决。采用基于共识的健康测量工具选择标准清单对方法学质量进行评分。随后，对每个问卷评估每个测量属性的证据水平。两名作者独立提取数据。任何分歧通过两人讨论解决。
五项研究中确定了五份问卷。肩痛和功能障碍指数以及肩部僵硬感测量量表的方法学质量水平最高。然而，在九项标准中只有两项具有出色的测量属性。此外，特别是在任何测量中均未调查内容效度。
有初步证据表明肩痛和功能障碍指数以及肩部僵硬感测量量表具有可靠性和有效性；然而，还需要进一步的大量研究。确定或开发具有内容效度的患者报告结局指标将是未来的研究议程。
