{"doi":"10.1101/2022.02.10.479324","title":"InfoMuNet: Information-theory-based Functional Muscle Network Tracks Sensorimotor Integration Post-stroke","abstract":"ABSTRACT Sensory information is critical for motor coordination. However, understanding sensorimotor integration is complicated, especially in individuals with nervous system impairment. This research presents a novel functional biomarker, based on a nonlinear network graph of muscle connectivity, called InfoMuNet, to quantify the role of sensory information in motor performance. Thirty-two individuals with post-stroke hemiparesis performed a grasp-and-lift task while muscle activities were measured using eight surface electromyography (sEMG) sensors. Subjects performed the task with their affected hand before and after exposure to the sensory stimulation elicited by performing the task with the less-affected hand. For the first time, this work shows that InfoMuNet robustly quantifies functional muscle connectivity improvements in the affected hand after exposure of the less-affected side to sensory information. >90% of the subjects conformed with the improvement resulting from this sensory exposure. InfoMuNet also shows high sensitivity to tactile, kinesthetic, and visual input alterations at the subject level, highlighting the potential use in precision rehabilitation interventions.","journal":"bioRxiv (Cold Spring Harbor Laboratory)","year":2022,"id":302670,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.7343,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":731187,"name":"Seyed Yahya Shirazi","orcid":"0000-0001-5557-259X","position":1,"is_corresponding":false},{"id":311824,"name":"Seda Bilaloglu","orcid":"0000-0002-0242-8348","position":2,"is_corresponding":false},{"id":915974,"name":"Shayan Jahed","orcid":null,"position":3,"is_corresponding":false},{"id":429909,"name":"Ramin Bighamian","orcid":"0000-0002-2660-0851","position":4,"is_corresponding":false},{"id":385205,"name":"Preeti Raghavan","orcid":"0000-0002-7852-5005","position":5,"is_corresponding":false},{"id":749920,"name":"S.
