“…Specifically, a consistent increase in accuracy can be observed as the window size increases. Current literature regarding window size segmentation have found that increasing the window size improves the accuracy up to a certain threshold [ 20 , 21 ]. Considering the current literature regarding the noisy nature of biological signals emitted from stroke survivors, this threshold might be larger for them.…”

“…Then the data was segmented using an overlapped segmentation method with a window size of 222 milliseconds and a step size of 55.6 milliseconds. Oskoei and Hu [ 21 ] found that an overlapping segmentation approach to EMG data with a window size of 200 milliseconds and a step size of 50 milliseconds provides a quick response time while Junior et al [ 20 ] recommends a step size of 500 milliseconds with a 25% overlap. Both of those studies were tested on healthy participants.…”

“…This was previously tested in [35] for a prosthetic task, was found to be suitable in this investigation. Additionally, it could be adapted for online applications, in which the offset time could be suppressed, and overlap segmentation could be applied to improve results [36,51].…”

“…It was chosen over other identification methods because it presents results higher than similar algorithms for sEMG signal in pattern recognition processes, such as the double threshold onset method [35]. The used method does not need adjustment of window size after the signal identification, which has an impact in accuracy for sEMG signal classification [36]. Our algorithm can identify the start and the end of an sEMG signal for each gesture, which was suitable for this offline application.…”
