由肌内压（IMP）升高引起的Combustion综合征以及由创伤或慢性过度使用引起的Combustion综合征通常需要侵入性IMP监测以进行准确诊断。我们的目标是测试一种非侵入性的超声技术，估计IMP的基础上筋膜位移波形从动脉血压脉冲。在本研究中，使用两个血压袖带覆盖从膝盖到脚踝的区域，将23名健康成人受试者腿部的IMP升高至80 mmHg。采用受试者操作特征（ROC）曲线和递归分割来确定使用筋膜移位诊断IMP升高的敏感性和特异性。对于一条ROC曲线，其中沿着使用多个超声测量参数以及受试者体重指数和血压，从升高的IMP（30 mmHg及以上）诊断正常IMP（低于30 mmHg）的灵敏度和特异性分别为0.61和0.94。将IMP分为三个范围（正常< 30 mmHg;中间范围30-40 mmHg和升高>= 50 mmHg）的递归划分导致诊断灵敏度提高（0.77），特异性几乎没有变化（0.93）。
Compartment syndromes, caused by elevated intramuscular pressure (IMP) and resulting from trauma or chronic overuse, frequently require invasive IMP monitoring for accurate diagnosis. Our objective is to test a non-invasive ultrasound technique for estimating IMP based on fascial displacement waveforms from arterial blood pressure pulses. In this study, IMP was increased in the legs of 23 healthy adult subjects up to 80 mmHg using two blood pressure cuffs covering the region from the knee to the ankle. Receiver operator characteristic (ROC) curves and recursive partitioning were used to determine the sensitivity and specificity of diagnosing elevated IMP using fascial displacement. For one ROC curve, in which several ultrasonic measurement parameters were used along with subject body mass index and blood pressure, the sensitivity and specificity for diagnosing normal IMP (below 30 mmHg) from elevated IMP (30 mmHg and up) was 0.61 and 0.94 respectively. Recursive partitioning, in which IMP was divided into three ranges (normal < 30 mmHg; mid-range of 30-40 mmHg and elevated >= 50 mmHg), resulted in improved diagnostic sensitivity (0.77) with almost no change in specificity (0.93).
