摘要
We divided the gait intention into 3 parts of start, stop and changing walking velocity using the fuzzy algorithm. Decision for gait initiation was determined when the difference of distance was larger than 5 cm between the right and left knee joint anterior displacements. The gait stop was registered when the differences were less than 4 cm after 7 measurements in an 80 m/s. The velocity changed when the distance difference value was more than 10 cm from the mean value of the knee joint anterior displacement values on both sides. Results also showed that the knee joint anterior displacement was efficient as a measurement benchmark for detecting gait intention. Potential use of the algorithm might be expected for older adults.
