Step counting is an important index of motion in telemonitoring. We have developed a wearable system based on a device with a force-sensing resistor. This is affixed at the calf gastrocnemius level to monitor the muscular expansion related to the gait. The gastrocnemius expansion measurement unit (GEMU) was tested on three subjects at Level 2 of the Tinetti test of unbalance, who performed five repetitions of 100 steps at two different speeds (normal and slow). The mean error was less than 0.5%. The GEMU also performed better than an accelerometer unit, which is normally considered to be the best solution for this disability. The system can be integrated into a routine home-care application based on a GSM home-care unit.
步数计数是远程监测中运动的一项重要指标。我们基于一种带有力敏电阻的设备开发了一种可穿戴系统。该设备固定在小腿腓肠肌水平,以监测与步态相关的肌肉扩张。在蒂内蒂不平衡测试2级的三名受试者身上对腓肠肌扩张测量单元(GEMU)进行了测试,这些受试者以两种不同速度(正常和缓慢)进行了5次100步的重复测试。平均误差小于0.5%。GEMU的表现也优于加速度计单元,加速度计单元通常被认为是针对这种残疾状况的最佳解决方案。该系统可以集成到基于GSM家庭护理单元的常规家庭护理应用中。
