A computerized tomographical (CT) study of the main dorsal neck muscles was performed on 60 subjects (30 males and 30 females) in order to quantify individual anatomical variations and to describe valid means of accurately inserting intramuscular wire electrodes in these deep and superimposed muscle layers. Depth and thickness of transverso-spinalis (TS), semispinalis capitis (SSC) and splenius capitis (SPL) muscles were measured on a cross-sectional image of the neck at the level of the fith cervical vertebrae. Thickness and depth were significantly greater in males than in females. SSC and SPL thicknesses were less than 10 mm in most subjects and their depths were highly variable depending on the subject's morphology. TS was thicker but its depth was also variable. This CT study clearly demonstrated that the interindividual variations of dorsal neck muscles are important and CT may provide a valid way to position wire electrodes accurately in most cervical muscles.
为了量化个体解剖学差异，并描述在这些深层重叠肌肉层中准确插入肌内金属丝电极的有效方法，我们对 60 名受试者（30 名男性和 30 名女性）进行了主颈背肌的计算机断层（CT）研究。在第 5 颈椎水平的颈部横截面图像上测量了横突棘肌（TS）、头半棘肌（SSC）和头夹肌（SPL）的深度和厚度。男性的深度和厚度均显著大于女性。在大多数受试者中，SSC 和 SPL 的厚度小于 10mm，其深度高度取决于受试者的形态。TS 较厚，但深度也有差异。这项 CT 研究清楚地表明，颈背肌的个体间差异很重要，CT 可能为大多数颈肌中准确放置金属丝电极提供一种有效的方法。
