    • A functional electrical stimulation brace responsive to various positions of an intended wearer's foot. The device includes a plurality of sensors positioned at different locations under the intended wearer's foot to detect the current position of the foot. Outputs from the sensors are fed to a controller that uses logic to activate an electrical stimulation unit that stimulates the peroneal muscles of a patient at the appropriate times during the patient's gait. The device may also employ mechanical stabilization of the ankle in addition to the functional electrical stimulation by means of an ankle foot orthosis with a variable resistance hinge. The electrodes are embedded in fixed locations in the brace upper portion so that optimal location of the electrodes relative to the peroneal muscles is maintained every time the device is applied. Also provided is a method for assistance and rehabilitation for a patient by electrical stimulation of the peroneal muscles. In the method, the position of the foot is detected and the peroneal muscles are stimulated responsive to particular positions of the patient's foot in order to activate the muscles at the appropriate times during the patient's gait. The device also provides lateral and torsional stability by means of the ankle-foot orthosis.
    • 一种功能性电刺激支架,其响应于预期佩戴者的脚的各种位置。 该装置包括位于目标佩戴者脚下的不同位置处的多个传感器,以检测脚的当前位置。 来自传感器的输出被馈送到控制器,该控制器使用逻辑来激活在患者的步态中适当的时间刺激患者的腓骨肌肉的电刺激单元。 除了通过具有可变电阻铰链的踝足矫形器的功能性电刺激之外,该装置还可以采用脚踝的机械稳定。 电极被嵌入在支架上部中的固定位置,使得每次施加装置时都保持电极相对于腓骨肌肉的最佳位置。 还提供了一种通过电刺激腓骨肌肉来为患者进行辅助和康复的方法。 在该方法中,检测脚的位置,并响应于患者脚的特定位置刺激腓骨肌肉,以便在患者的步态中适当的时间激活肌肉。 该装置还通过踝足矫形器提供横向和扭转稳定性。
