The purpose of this study was to determine age-related changes of scapula muscles using ultrasound and surface electromyography. Fifty eight subjects (20's to 30's: 18 people, 40's to 50's: 13 people, 60's to 70's: 27 people) were recruited in this study. Thicknesses and activities of the upper and lower trapezius, serratus anterior, and middle deltoid muscles were measured with ultrasonography and surface electromyography, respectively. In scapula muscles, only lower trapezius has a tendency to decrease in muscle thickness. In muscle activity, there was no difference among three groups. These findings suggested that only lower trapezius might become weaken selectively due to reduction of muscle volume with aging, although the function of the muscle would not change.

这项研究的目的是使用超声和表面肌电图确定肩cap骨肌肉的年龄变化。在这项研究中招募了58名受试者（20至30年代：18人，40到50岁：13人，60至70：27人：27人）。分别用超声检查和表面肌电图测量上和下斜方肌，前后三角肌的厚度和活性。在肩cap骨肌肉中，只有较低的斜方肌具有减少肌肉厚度的趋势。在肌肉活动中，三组之间没有差异。这些发现表明，尽管肌肉的肌肉功能不会改变，但由于肌肉体积的减小，较低的斜方肌可能会有选择地削弱。
