Research Abstract |
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.
