Visual scoring used epochs of 5-second duration, and in each epoch, electromyographic activity of tibialis anterior muscle was classified in eight types on the basis of its duration and amplitude. Activity levels of the actigraphic data were logged in 5-second intervals and stored in memory for computer retrieval. To assess the reproducibility of actigraphic detection…
