Non-magnetic equipment for the high-resolution quantification of finger kinematics during functional studies of bimanual coordination

Dystonic neck muscles show a shift in relative autospectral power during isometric contractions

“…The first two seconds of each trial were discarded and repetitions were concatenated, resulting in 16 seconds of data for analysis per task. The raw bipolar EMG was notch filtered at 50 Hz, high pass filtered at 20 Hz (4 th order zero-phase Butterworth) and full wave rectified (De Luca et al, 2010). Data was then sectioned into segments of two seconds, over which autospectra were calculated and averaged over the segments resulting in a frequency resolution of 0.5 Hz.…”
