Our advances in the detection of the swing phase in foot drop gait using an acceleration sensor was described. The heel sensor system was used for the restoration of foot drop gait with functional electrical stimulation (FES) in our group. However there are still complications when placing the heel sensor. To replace the heel sensor, we measured the acceleration of the thigh during gait using an acceleration sensor. The detector was synthesized using a rule induction algorithm, by the name of, Neural Network. We have applied a signal for heel contact in a gait using the heel sensor before training with the Neural Network. The accuracy of the Neural Network detector was compared with a swing phase detector based on the heel sensor. The Neural Network detector was able to detect similarly the swing phase in the heel sensor. The largest difference in timing was less than 60 msec. An acceleration sensor, which was put on the thigh, was useful in detection the swing phase.

描述了使用加速传感器在脚下步态检测挥杆阶段方面的进步。脚跟传感器系统用于恢复我们组中具有功能性电刺激（FES）的脚下步态。但是，放置脚跟传感器时仍然存在并发症。为了替换脚跟传感器，我们使用加速度传感器测量了步态过程中大腿的加速度。使用规则感应算法通过神经网络的名称合成检测器。在使用神经网络训练之前，我们已经使用脚跟传感器在步态中应用了脚跟接触的信号。将神经网络检测器的精度与基于脚跟传感器的摇摆相检测器进行了比较。神经网络检测器能够在脚后跟传感器中类似地检测到挥杆阶段。时间上最大的差异小于60毫秒。放置在大腿上的加速度传感器可用于检测挥杆阶段。
