Trigger points (TrPs) in the lower-limb are under-investigated and may be a contributory factor in knee pathologies.
The purpose of this study was to establish the intra-rater reliability of assessing the location and severity of latent TrPs in the quadriceps.
Twenty-nine asymptomatic subjects were palpated for TrPs in the middle and quadriceps. The location and severity was then measured using the anatomical landmark system (ALS) and pain pressure threshold (PPT). The subject was re-tested the next day.
The intra-class coefficient [ICC] for the ALSs and PPTs were found to be reliable. Gender appears to be a factor in the severity of TrPs in the quadriceps. Females reported some of the features of TrPs more often than males (jump sign, twitch response, referred pain).
Further investigation is needed to understand the relationship between TrPs around the knee and knee pathologies, particularly in females.
下肢触发点（TrP）的研究较少，可能是膝关节病变的一个促成因素。
本研究的目的是确定评估股四头肌中潜在触发点位置和严重程度的评分者内信度。
对29名无症状受试者的股四头肌中部进行触发点触诊。然后使用解剖标志系统（ALS）和疼痛压力阈值（PPT）测量其位置和严重程度。次日对受试者进行重新测试。
发现ALS和PPT的组内相关系数[ICC]可靠。性别似乎是股四头肌触发点严重程度的一个因素。女性比男性更频繁地报告触发点的一些特征（跳跃征、抽搐反应、牵涉痛）。
需要进一步研究以了解膝关节周围触发点与膝关节病变之间的关系，尤其是在女性中。
