Application of a New Muscle Exercise Device using Intermittent Sole Pressure Stimulation

我们开发了一种床上肌肉训练装置，利用位于鞋底的椭圆形橡胶气球的间歇性膨胀。我们使用我们开发的装置来测定肌肉运动时下肢肌肉的活动。在30度和70度半卧位间歇足底压力刺激（ExISPS）下进行腿部运动时，股内侧肌、股二头肌长头肌和腓骨内侧肌肌电图均方根值模拟或大于日常生活中需要进行的站立、举犊等腿部活动。ExISPS可以作为运动训练来维持需要卧床休息的患者的下肢功能。

We developed an on-the-bed muscle training device that utilizes the intermittent inflation of an oval rubber balloon located at the sole. We determined the lower-limb muscle activities during muscle exercise using the device we developed. The root-mean-square of electromyogram values of vastus medialis, long head of the biceps femoris, and gastrocnemius medialis during the leg exercise against intermittent sole pressure stimulation (ExISPS) in 30-degree and 70-degree semi-recumbent positions mimic or are greater than those activities of the leg that are required in daily life such as standing up and calf-raising. The ExISPS could be used as exercise training to maintain lower-limb function in patients who need bed-rest.
