Thresholding the peaks to locate the Q-waves results in detection of unwanted peaks as the Q-waves are buried in noise. Discern the vowels and consonants in the word by finding the points at which the variance of the signal changes significantly. The onset of movement was detected with a maximum sensitivity of 89.3% for Go-forward and 60.9% for Go-backward events. 2) the false alarm rate (FAR) = the number of spikes reported . Onset detection time can be determined using a dedicated device such as a release switch (Mushiake et al., 1997), but this usually limits the subjects to specific point in space and restricts the experimental setup.Alternately, onset detection time can be estimated from the tracked trajectory as measured by a tracking system, such as a magnetic/optical tracker (van Beers et al., 2004), or via .
