The biomechanical influence of brace treatment for scoliosis is not understood. This prospective pilot study analyzed reliability of a system based on 100% textile sensors for measurement of pressure exerted by brace on trunk. Evaluation of modifications during changes in the location of the support zones and variations in amplitude of the pressure was observed in four patients, when considering three main daily positions mimicking day and nighttime wear. A calibration step allowed the determination of a conversion law between sensor data and pressure unit using a second order polynomial function with a high r of 0.99. This prototype is the first of a new generation. Experimental pressure distribution could be useful for the further brace development.
支具治疗脊柱侧弯的生物力学影响尚不清楚。本前瞻性初步研究分析了基于 100%纺织传感器系统测量支具对躯干压力的可靠性。当考虑模仿白天和夜间穿戴的三个主要日常位置时，对四个患者在支撑区域位置变化和压力幅度变化时的变化进行了评估。通过使用二次多项式函数进行校准步骤，确定了传感器数据与压力单位之间的转换定律，该函数的 r 高达 0.99。该原型是新一代的第一个原型。实验压力分布可能有助于进一步开发支具。
