To investigate the test-retest reliability of the following clinical diagnostic characteristics of myofascial trigger points: taut band, spot tenderness, jump sign, pain recognition, referred pain and local twitch responses (LTRs).
Test-retest reliability study.
This study was undertaken in an outpatient physiotherapy department.
Fifty-eight patients (31 males and 27 females) with rotator cuff tendonitis were recruited into this study.
Rotator cuff muscles were assessed by an expert for the presence or absence of the main clinical diagnostic characteristics of trigger point assessment. The process was then repeated three days later by the same expert.
Outcomes included the presence or absence of: a taut band, spot tenderness, jump sign, pain recognition, referred pain and LTRs.
Kappa values between testing situations for the taut band, spot tenderness, jump sign and pain recognition were 1. Kappa scores for referred pain ranged between 0.79 and 0.88 and for the local twitch response between 0.75 and 1 depending on the muscles under investigation.
The presence or absence of the taut band, spot tenderness, jump sign and pain recognition was highly reliable between sessions. Referred pain and local twitch response reliability varied depending on the muscle being studied.
研究肌筋膜触发点以下临床诊断特征的重测信度：紧张带、压痛点、跳跃征、疼痛识别、牵涉痛和局部抽搐反应（LTRs）。
重测信度研究。
本研究在门诊理疗科进行。
招募了58例肩袖肌腱炎患者（31例男性和27例女性）参与本研究。
由一名专家评估肩袖肌肉是否存在触发点评估的主要临床诊断特征。三天后，同一名专家再次进行评估。
结果包括紧张带、压痛点、跳跃征、疼痛识别、牵涉痛和LTRs的有无。
紧张带、压痛点、跳跃征和疼痛识别在不同测试情况下的kappa值为1。牵涉痛的kappa评分在0.79至0.88之间，局部抽搐反应的kappa评分在0.75至1之间，具体取决于所研究的肌肉。
紧张带、压痛点、跳跃征和疼痛识别的有无在不同测试之间具有高度可靠性。牵涉痛和局部抽搐反应的可靠性因所研究的肌肉而异。
