目的
确定使用高频磁刺激器诱导强烈肌肉收缩的最佳刺激部位和技术。
方法
高频磁刺激管理的权利股外侧肌（VL）的8名健康成人在最大强度的范围内的可耐受的疼痛。刺激部位如下：A部分，髌骨基部外侧边缘（LEBP）和大腿远端三分之一（D点）之间的区域; B部分，D点和大腿近端三分之一（P点）之间的区域。磁刺激（Stim-MCF）引起的肌肉收缩力的等距两个部分之间进行了比较。
结果
B段的Stim-MCF显著高于A段。此外，对刺激敏感的部位局限于A部分D点附近的狭窄区域和B部分D点和P点之间的中心部分。两个部分的疼痛程度都很低。
结论
磁刺激VL的最佳部位仅限于大腿的中央部分。除了浅近端子分支之外，深近端子分支和/或深簇运动神经末梢可能已经被刺激。我们的研究结果表明，移动探针是一种有用的方法来确定引起最强肌肉收缩力的部位。

Purpose
To identify the optimal stimulation site and technique for inducing strong muscle contraction using a high-frequency magnetic stimulator.
Methods
High-frequency magnetic stimulation was administered to the right vastus lateralis (VL) of eight healthy adults at maximal intensity within the range of tolerable pain. The stimulation sites were as follows: section A, the area between the lateral edge of the base of the patella (LEBP) and the distal one-third of the thigh (point D); section B, the area between point D and the proximal one-third of the thigh (point P). Isometric maximal muscle contraction forces induced by magnetic stimulation (Stim-MCF) were compared between the two sections.
Results
The Stim-MCF was significantly higher in section B than in section A. Additionally, the sites susceptible to stimulation were confined to a narrow area near point D in section A and the central part between points D and P in section B. The degree of pain was very low in both sections.
Conclusion
The optimal site for magnetic stimulation of the VL was limited to the central part of the thigh. In addition to the superficial proximal sub-branch, the deep proximal sub-branch and/or deeply clustered motor nerve endings may have been stimulated. Our results suggested that moving the probe was a useful way to identify the site that elicited the strongest muscle contraction force.
