Using a three-dimensional model, the theoretical maximal forces that can be generated by electrical stimulation of several posterior thoracic muscles have been analyzed to investigate the kinesiology of scoliosis. None provides a pure lateral bending moment, and most exaggerate lordosis. None satisfactorily generates a rotary force for correction of scoliotic deformity. Although maximum muscle contraction can ideally produce lateral bending moments of the same magnitude as the Milwaukee brace, current techniques do not cause continuous, complete muscle contraction. The best muscle studied for electrospinal intrumentation is the lateral erector spinae. Multiple sites of stimulating electrodes are probably necessary. None of the individual muscles studied is ideal. Further investigation should be directed to the stimulation of anterior thoracic muscles.
利用三维模型，已对电刺激几块胸后肌所能产生的理论最大力量进行了分析，以研究脊柱侧弯的运动学。没有一块肌肉能产生单纯的侧方弯曲力矩，且大多数会加剧脊柱前凸。没有一块肌肉能令人满意地产生用于矫正脊柱侧弯畸形的旋转力。尽管最大肌肉收缩理论上可产生与密尔沃基支具相同大小的侧方弯曲力矩，但目前的技术无法引起持续、完全的肌肉收缩。用于电脊髓器械研究的最佳肌肉是竖脊肌外侧肌。可能需要多个刺激电极位点。所研究的任何一块单独肌肉都不理想。进一步的研究应针对胸前肌的刺激。
