INTRODUCTION
Recent papers indicate that one-side mastectomy can produce deleterious effects on the posture and musculoskeletal system. This study was conducted to better understand the underlying mechanisms involved in trunk motion in external prosthesis users.
OBJECTIVE
The aim was to evaluate the changes in surface electromyographic (SEMG) activity of the erector spinae muscles (ES) in postmastectomy women with and without breast prostheses during functional body movement tests.
METHODS
In 51 one-side postmastectomy women the SEMG muscle activity of bilateral ES was measured during symmetrical and asymmetrical dynamic activities in a counterbalanced manner with different weights of the breast prosthesis. Range-of-motion measurements were taken for forward bending, backward bending, lateral bending, and rotation.
RESULTS
The mean level of the ES activity in the lumbar region was not affected by the weight of the external breast prosthesis during most of the functional body tests ( > 0.05). The activity of ES during functional body tests with and without different external breast prostheses did not differ between the two sides of the trunk (mastectomy and nonmastectomy) for most of the movement tests ( > 0.05).
CONCLUSION
The lumbar ES activity during functional tests is not associated with the weight of the external breast prosthesis in postmastectomy women.
简介
最近的研究表明，乳腺癌根治术后可能对患者的姿势和骨骼肌肉系统产生有害影响。本研究旨在更好地理解假体使用者躯干运动的潜在机制。
目的
评估乳腺癌根治术后女性在佩戴和不佩戴乳房假体进行躯体功能性运动测试时，脊柱伸肌（ES）的表面肌电（SEMG）活动的变化。
方法
51 例单侧乳腺癌根治术后女性，以双侧 ES 的 SEMG 肌肉活动为测量指标，采用双侧对比的方式，在对称和不对称的动态活动中，佩戴不同重量的乳房假体进行测试。对前屈、后伸、侧屈和旋转运动进行了运动范围测量。
结果
在大多数躯体功能性测试中（> 0.05），外部乳房假体的重量对腰椎区 ES 活动的平均水平没有影响。在大多数运动测试中（> 0.05），佩戴和不佩戴不同外部乳房假体的躯体功能性测试中，躯干两侧（乳腺癌根治术侧和非乳腺癌根治术侧）的 ES 活动无差异。
结论
在乳腺癌根治术后女性中，外部乳房假体的重量与躯体功能性测试中的腰椎 ES 活动无关。
