Simulated and experimental HDEMG signals of biceps brachii muscle for analysis of motor unit mergingHolobar, Aleš (Avtor) Škarabot, Jakob (Avtor) Farina, Dario (Avtor) surface high density electromyogram (HDEMG)motor unitspike trainmotor unit mergingsimulated dataexperimental databiceps brachiidatasetThis dataset contains a collection of simulated and experimental surface HDEMG recordings of the biceps brachii muscle during the isometric elbow flexion. Simulated data contains 50 recordings: 5 subjects and 5 excitation levels, each with and without added noise. Experimental data contains 16 recordings: 2 subjects with 4 excitation levels and 2 repetitions of each level. Synthetic data was simulated using the cylindrical volume conductor model [1] and the motor unit recruitment and firing modulation model proposed in [2]. Each recording is 20 seconds in length with 90 HDEMG channels sampled at 2048 Hz and is stored as a 2D matrix of raw EMG values in Matlab’s MAT format. Experimental surface EMG data was recorded on two volunteers during isometric contractions at constant force level. Each recording is 25 seconds in length with 64 HDEMG channels sampled at 2048 Hz and is also stored as a 2D matrix of raw EMG values in Matlab’s MAT format. The dataset is approximately 1.5 GB in size.s. n.20242024-05-29 22:03:01Drugo88844sl
