Abstract：
This study aimed to use a musculoskeletal model to predict changes in spinal moments following simulated breast surgery. A female full body musculoskeletal model with a fully articulated thoracolumbar spine and independent moveable breast segments was customised for this study. Key findings suggest that the simulated removal of breast tissue (750 g to 1501 g) can reduce the magnitude of lumbar spine extensor moments by >0.05 Nm/kg during walking and jogging. A customised female whole-body musculoskeletal model is capable of providing a first approximation of changes in spinal loading following simulated breast surgery.
摘要：
这项研究旨在使用肌肉骨骼模型来预测模拟乳房手术后脊柱力矩的变化。本研究定制了具有全关节胸腰椎和独立可移动乳房节段的女性全身肌肉骨骼模型。关键发现表明，模拟切除乳房组织（750g至1501g）可以在步行和慢跑期间将腰椎伸肌力矩的大小减少>0.05Nm/kg。定制的女性全身肌肉骨骼模型能够提供模拟乳房手术后脊柱负荷变化的第一近似。
