Limited lower trunk rotation, which includes rotation of the lumbar spine, may hinder or even prevent functional activities. Currently, due to the lack of reliable, valid, and clinically useful tests, there is no standard objective measure of lower trunk rotation that can be easily performed in the clinic. The purpose of this study was to establish a standard protocol and to determine inter-rater and intra-rater reliability for a goniometric measurement developed to measure lower trunk rotation.
Lower trunk rotation was measured using a specific, goniometric method in 41 subjects. Each subject was measured 6 times by 2 different examiners for a total of 12 measurements.
Pearson correlation coefficients indicate good intra-rater reliability ranging from 0.59 to 0.82 for right rotation (P< 0.001) and 0.76 to 0.82 for left rotation (P< 0.001), as well as good inter-rater reliability ranging from 0.62 to 0.83 with right rotation (P< 0.001) and 0.75 to 0.77 for left rotation (P< 0.001).
This measure of trunk rotation may be useful for objectively documenting lower trunk rotation.
下躯干有限的旋转，包括腰椎的旋转，可能会阻碍甚至妨碍功能活动。目前，由于缺乏可靠、有效且临床实用的测试方法，临床上尚无一种可轻松进行的下躯干旋转的标准客观测量方法。本研究的目的是建立一个标准方案，并确定一种用于测量下躯干旋转的角度测量法的评分者间和评分者内信度。
采用特定的角度测量法对41名受试者的下躯干旋转进行测量。每位受试者由2名不同的检查者测量6次，共进行12次测量。
皮尔逊相关系数表明，评分者内信度良好，右侧旋转为0.59至0.82（P<0.001），左侧旋转为0.76至0.82（P<0.001）；评分者间信度也良好，右侧旋转为0.62至0.83（P<0.001），左侧旋转为0.75至0.77（P<0.001）。
这种躯干旋转测量方法可能有助于客观记录下躯干旋转情况。
