The present study assesses the biomechanical effectiveness of the Boston brace on a group of 14 patients with adolescent scoliosis. Interface pressure measurements were performed at the appropriate compression pads within the brace when it was first applied and on two further sessions within the 6-month period of brace treatment. A corresponding series of Cobb angle measurements also were performed. Mean values of total force exerted through the brace of 58 +/- 18 N were associated with an initial curve correction of 37 +/- 21%. This mean force level was maintained throughout the study, although the mean curve correction at 6 months had reduced to 15 +/- 14%. In addition to biomechanical parameters, factors relating to the nature of the individual curve were important in determining the overall effectiveness of the Boston brace system.
本研究评估了波士顿 brace 对一组 14 例青少年特发性脊柱侧弯患者的生物力学效果。在首次佩戴 brace 时以及在 brace 治疗的 6 个月期间的另外两次随访中,在 brace 内适当的压迫垫处进行界面压力测量。同时进行了一系列相应的 Cobb 角测量。通过 brace 施加的总力平均值为 58±18N,初始曲线矫正率为 37±21%。尽管在 6 个月时平均曲线矫正率已降至 15±14%,但在整个研究过程中该平均力水平保持不变。除了生物力学参数外,与个体曲线性质相关的因素在确定波士顿 brace 系统的整体有效性方面也很重要。
