Previous literatures showed no evidence that wearing an external breast prosthesis may prevent changes in body posture in women who underwent mastectomy.
To determine whether the weight of an external breast prosthesis can contribute to posture changes in women post mastectomy.
Fifty-one women with unilateral mastectomy (age 58 ± 11.39 years) were divided into 2 subgroups by their operation side. Asymmetry of body posture was evaluated by using the electromyography activity of erector spinae muscles with four different weights of breast prosthesis.
Despite the operation side, the erector spinae muscle activities on the operation side and non-operation side were significantly different. Overall, for patients who had operation on the left side, their erector spinae muscle activity imbalance will be smaller, compared to the imbalance among patients with right operation side. The weight of the external breast prosthesis did not influence the differences of erector spinae muscle activities on the operation side and non-operation side.
The weight of an external breast prosthesis for women after mastectomy may not be crucial when choosing a proper prosthesis.
既往文献表明，没有证据显示佩戴外部乳房假体可预防接受乳房切除术的女性身体姿势的改变。
确定外部乳房假体的重量是否会导致乳房切除术后女性的姿势改变。
51例单侧乳房切除术患者（年龄58±11.39岁）按手术侧别分为2个亚组。使用竖脊肌的肌电图活动，对4种不同重量的乳房假体进行身体姿势不对称性评估。
无论手术侧别如何，手术侧和非手术侧的竖脊肌活动均存在显著差异。总体而言，左侧手术患者的竖脊肌活动失衡比右侧手术患者的失衡更小。外部乳房假体的重量并未影响手术侧和非手术侧竖脊肌活动的差异。
对于乳房切除术后的女性，选择合适的假体时，外部乳房假体的重量可能并非关键因素。
