| Popis: | In the coherence analysis of muscles, beta bands of 15-35 Hz were reflecting activation of corticospinal tract (CST). The purpose of this study was to investigate the participation of activation of CST during dual task walking by electromyography (EMG) coherence analysis in healthy adults. Six healthy subjects were performed two types walking in a straight; A) normal walking, B) calculation task during walking. The walking performances were recorded using a video camera. The stride and cadence of steps, walking speed were measured from video movies. EMG signals were measured from proximal and distal of tibial anterior, medial gastrocnemius, and soleus muscles of right leg, and these were analyzed integrated EMG and coherence of flexor and extensor muscles. The walking speed, stride, and cadence of dual task condition were decreased compared with normal walking. Integrated EMG of proximal of tibial anterior was decreased in dual task walking. The coherence of EMG activity during dual task walking was not significantly changed flexor and extensor muscles compared to normal walking. These results suggested that the change of walking performance during dual task condition might not be due to decrease of input from CST to motor neurons. In addition, the measurement method of cognitive function during walking was necessary of other way to investigation. |
