We performed a study on 32 idiopathic scoliotic patients (30 females, 2 males) treated with a Chêneau brace. Eighteen patients had a single right thoracic curve and 14 had a single right thoracolumbar curve. We used the TekScan system (ClinSeat Type 5315 Sensor, TekScan, Boston MA, USA) to measure pressures at the skin-brace interface, assess the effect of strap tension and analyze the variation of these pressures with position and activity. The TekScan device enabled identification of the pressure areas corresponding to the brace's three loading points. The pressure under the main pad had a greater mean value than the pressure under the two counter-pads. Tightening the straps led to a significant increase in the pressures, whatever the position studied or the curve pattern. Compared with the standing (reference) position, we observed significantly higher pressures during maximal inspiration (p < 0.001) and lower pressures during maximal expiration, in the prone position and after having risen from a lying position, for both thoracic curves (p < 0.001) and thoracolumbar curves (p < 0.01). The pressures for thoracolumbar curves were lower than those for thoracic curves, whatever the position studied and both before and after strap adjustment. For lying positions, lying on the right side produced the greatest increase pressure. Even though the TekScan system does not provide direct information on the correction of spinal curvature, it appears to be a useful tool in the treatment of scoliotic patients. Strap adjustment clearly influences the applied pressures - particularly those on the rib cage. During activity, there is a natural tendency to decrease the pressure; this justifies efforts to maintain strap tensions in general and during day wear in particular.
我们对32例接受施诺支具治疗的特发性脊柱侧凸患者（30例女性，2例男性）进行了一项研究。18例患者有单一的右胸弯，14例有单一的右胸腰弯。我们使用TekScan系统（ClinSeat Type 5315传感器，TekScan，美国马萨诸塞州波士顿）测量皮肤与支具界面处的压力，评估束带张力的影响，并分析这些压力随体位和活动的变化。TekScan设备能够识别与支具三个加载点相对应的压力区域。主衬垫下的压力平均值高于两个副衬垫下的压力。无论所研究的体位或弯曲类型如何，束带收紧都会导致压力显著增加。与站立（参考）位相比，我们观察到在最大吸气时压力显著升高（p<0.001），在最大呼气时、俯卧位以及从卧位起身时，胸弯（p<0.001）和胸腰弯（p<0.01）的压力均显著降低。无论所研究的体位以及束带调整前后，胸腰弯的压力均低于胸弯。对于卧位，右侧卧位产生的压力增加最大。尽管TekScan系统未提供关于脊柱侧弯矫正的直接信息，但它似乎是治疗脊柱侧凸患者的一种有用工具。束带调整明显影响所施加的压力，尤其是对胸廓的压力。在活动期间，压力有自然降低的趋势；这证明了总体上尤其是日间佩戴时保持束带张力的努力是合理的。
