INTRODUCTION
Pressure monitoring is crucial for effective pressure therapy. Precise and reliable interface pressure measurement system, however, remains unavailable in current practice.
METHODOLOGY
This is a validation study on the application of a recently developed device, the Pliance X System, for static interface pressure measurement. Sensor properties were evaluated through series of laboratory tests in the first phase of the study. Phase II was a clinical study using the Pliance X system to differentiate the loading generated on the patients' scars through additional inserts and pressure garment.
RESULTS
Results showed high test-retest and inter-rater reliability (ICC > or = 0.995) with good linearity (adjusted R-square=0.997) by measuring standard weights. The maximum deviation between the measurement generated by the sensor and the sphygmomanometer cuff was +/-1.451 mmHg. Results in the clinical trial revealed its discriminant ability in distinguishing different levels of pressure loading on patients with scars (p<0.01).
CONCLUSION
The commercially available pressure measurement system was found to be a reliable tool for measurement of low interface pressure under static condition.
引言
压力监测对于有效的压力治疗至关重要。然而，目前临床上仍缺乏精确且可靠的界面压力测量系统。
方法
这是一项关于最近开发的用于静态界面压力测量的设备——Pliance X系统应用的验证研究。在研究的第一阶段，通过一系列实验室测试评估传感器特性。第二阶段是一项临床研究，使用Pliance X系统通过额外的衬垫和压力衣来区分患者疤痕上产生的负荷。
结果
通过测量标准重量，结果显示重测信度和评分者间信度较高（组内相关系数ICC≥0.995），线性良好（调整后的决定系数R² = 0.997）。传感器测量值与血压计袖带测量值之间的最大偏差为±1.451 mmHg。临床试验结果显示其在区分疤痕患者不同压力负荷水平方面具有判别能力（p<0.01）。
结论
发现市售压力测量系统是在静态条件下测量低界面压力的可靠工具。
