The purpose of the study was the non-invasive investigation of the innervation zone (IZ) location of the gracilis muscle of both thighs by means of surface electromyography (EMG).
Multichannel EMG signals were detected by means of a flexible array of 16 equally spaced silver bar electrodes. Tests were performed on both gracilis muscles on 15 subjects. Motor unit (MU) action potentials were visually identified and extracted. The locations of the IZs of the recognized MUs were statistically analyzed to find significant differences between the subjects and between the right and left muscle of each subject.
A statistically significant difference was found between the gracilis IZ position in the two sides, with more proximal IZs on the left side. This difference suggests a possible role of surface EMG in preoperative evaluation of patients prepared for the dynamic graciloplasty procedure. This test would provide an objective criterion for the choice of the gracilis muscle to be transposed with the highest probability of success.
本研究旨在通过表面肌电图（EMG）对双侧大腿股薄肌的神经支配区（IZ）位置进行无创性研究。
采用由16个等间距银条电极组成的柔性阵列检测多通道肌电信号。对15名受试者的双侧股薄肌进行测试。目视识别并提取运动单位（MU）动作电位。对识别出的运动单位的神经支配区位置进行统计分析，以找出受试者之间以及每个受试者左右肌肉之间的显著差异。
发现双侧股薄肌神经支配区位置存在统计学显著差异，左侧的神经支配区更靠近近端。这种差异表明表面肌电图在为动态股薄肌成形术做准备的患者术前评估中可能发挥作用。该测试将为选择最有可能成功移位的股薄肌提供客观标准。
