A scheme for optimizing configurations in models of skeletal structures is presented. Use of the scheme is illustrated through determination of biomechanically optimal correction of a right-thoracic scoliosis by passive brace and active muscle forces. The locations and magnitudes of the passive brace forces, and the trunk muscle groups and their corresponding contraction intensity magnitudes that would optimally correct the geometric deformities of the spine were determined. The results suggest that, from a biomechanical viewpoint, both brace and muscle forces are capable of substantial correction of a model thoracic scoliosis. However, comparison of model results with long-term clinical results suggests that even under optimal conditions it is unlikely that scoliosis can be fully corrected by passive brace forces or active muscle contractions.
本文提出了一种用于优化骨骼结构模型配置的方案。通过确定被动支具和主动肌肉力量对右胸段脊柱侧弯进行生物力学优化矫正的过程，说明了该方案的应用。确定了被动支具力的位置和大小，以及能最佳矫正脊柱几何畸形的躯干肌肉群及其相应的收缩强度大小。结果表明，从生物力学角度来看，支具和肌肉力量都能够对模型胸段脊柱侧弯进行显著矫正。然而，模型结果与长期临床结果的比较表明，即使在最佳条件下，脊柱侧弯也不太可能通过被动支具力或主动肌肉收缩得到完全矫正。
