This approach can be used for inferring the voluntary commands in neural interfaces in patients with limb amputations. This paper proposes for the first time an innovative method for fully automatic and real-time intramuscular EMG (iEMG) decomposition. The method is based on online single-pass density-based clustering and adaptive classification of bivariate features, using the concept of potential measure. No attempt was made to resolve superimposed motor unit action potentials. The proposed algorithm was validated on sets of simulated and experimental iEMG signals. Signals were recorded from the biceps femoris long-head, vastus medialis and lateralis and tibialis anterior muscles during low-to-moderate isometric constant-force and linearly-varying force contractions. The average number of missed, duplicated and erroneous clusters for the examined signals was [Formula: see text], [Formula: see text], and [Formula: see text], respectively. The average decomposition accuracy (defined similar to signal detection theory but without using True Negatives in the denominator) and coefficient of determination (variance accounted for) for the cumulative discharge rate estimation were [Formula: see text], and [Formula: see text], respectively. The time cost for processing each 200[Formula: see text]ms iEMG interval was [Formula: see text] (21\u201397)[Formula: see text]ms. However, computational time generally increases over time as a function of frames\/signal epochs. Meanwhile, the incremental accuracy defined as the accuracy of real-time analysis of each signal epoch, was [Formula: see text]% for epochs recorded after initial one second. The proposed algorithm is thus a promising new tool for neural decoding in the next-generation of prosthetic control.<\/jats:p>","DOI":"10.1142\/s0129065717500253","type":"journal-article","created":{"date-parts":[[2017,3,21]],"date-time":"2017-03-21T02:32:13Z","timestamp":1490063533000},"page":"1750025","source":"Crossref","is-referenced-by-count":33,"title":["A Real-Time Method for Decoding the Neural Drive to Muscles Using Single-Channel Intra-Muscular EMG Recordings"],"prefix":"10.1142","volume":"27","author":[{"given":"Saeed","family":"Karimimehr","sequence":"first","affiliation":[{"name":"Faculty of Engineering, Biomedical Engineering Department, University of Isfahan, HezarJerib st., 81746-73441 Isfahan, Iran"},{"name":"Brain Engineering Research Center, Institute for Research in Fundamental Sciences (IPM), P.
