BACKGROUND: Transcranial direct current stimulation (tDCS) seems to facilitate and/or inhibit neural activity and improve motor function in neurological patients. However, it is important to confirm such improvements as well as determine the association between neurophysiological changes and the enhancement of motor control. RESEARCH QUESTION: Does the improvement of motor control in neurological patients after transcranial direct current stimulation translate into changes in the motor evoked potential? METHODS: A systematic electronic search strategy was employed to identify studies indexed in the PubMed, BIREME, and COCHRANE databases using a combination of search terms adapted to each database: transcranial direct current stimulation; evoked potential motor; and motor control...

BACKGROUND: Movement intentions are generally classified by Electroencephalogram (EEG) and have been used in gait initiation prediction. However, it is not easy to collect EEG data and practical in reality. Alternatively, ground reaction force (GRF) and the center of pressure (COP) is produced by the contact between the foot and the ground during a specific period of walking, which are the characteristics of evaluating gait performance RESEARCH QUESTION: The study aims to use a deep learning technique to recognize the data of the COP and GRF to classify straight walking and right turn...
