We want to identify the differences in MRCP's and ERD's during dynamic wrist and hand movement. What parameters would be important to investigate when the differences will serve to the development of a platform for BCI- (neurofeedback) rehabilitation? We are already extractiong the time and amplitude of Peak negativity and could look at the rebound rate. What else would you recommend?
Hi, have you looked at pre-movement (~ -300msec) laterality of the ERD of the low beta range (12-20Hz) ?
You may look at three recent papers by C.Tangwiriyasakul et.al. Of course, the ERD pertains to a certain eeg frequency band (beta, mu, alfa); so, proper filtering and sampling to determine spectral contributions from the full time signal are paramount.
Correcting for disturbing eeg contributions (eyes, muscles) is also most important.
It would be interesting to quantitate the cortical potentials to wrist flexion torque, wrist extension torque, with prescribe torque objectives, in regard to velocity of torque development, amplitude of torque generated. Then compare rhythmic patterns with alternation of flexion and extensor movement responding to movement cueing in regard to direction, velocity, and force.
