Abstract: For rehabilitation persons suffering from neuro-musculoskeletal disorders technology has given enough power. This can be done through active orthotic devices. For optimal control and assistance of these devices, there is a need of bio-controlled closed loop assistance system such as BCI. It is a complex interaction when working in an assist as needed mode and synchronization between voluntary and involuntary movements of the joint is required. In this context, the aim of this study is to investigate the EEG dynamics associated with both voluntary and involuntary movements of the ankle joint. Frontal and primary motor cortex position are considered for this study. The results determine that the neural signals governing these two types of activities are different. Studies show that the gamma band is prominent in attention which also supports our hypothesis in the case of voluntary and involuntary movements. Similarly, we further extend this experiment for voluntary and involuntary gait cycle using exoskeleton. These synchronized voluntary and involuntary movements signal may be used in the brain-computer interface to restore human gait function.
