We propose to evaluate a commercially available low-cost system compared to a reference system in participants with stroke-related movement disorders in functional situations. Methods: Three hemiparetic participants performed three functional tasks: two treadmill walks at different speeds and a sit-to-stand test. The vastus lateralis and gastrocnemius medialis muscles were equipped with two EMG sensors. The comparison between the two EMG systems was based on 883 identified cycles. Spearman\u2019s correlation coefficients (SCs), linear correlation coefficients (LCCs), and cross-correlation coefficients (CCCs) were calculated. Results: The main results indicate good to very good similarity of the EMG signals collected from the two tested sEMG systems. In the comfortable-walking condition, an SC of 0.894 \u00b1 0.091 and an LCC of 0.909 \u00b1 0.094 were noted. In the fast-walking condition, an SC of 0.918 \u00b1 0.064 and an LCC of 0.935 \u00b1 0.056 were observed. For the 1 min sit-to-stand test, an SC of 0.880 \u00b1 0.058 and an LCC of 0.881 \u00b1 0.065 were noted. Conclusions: This study demonstrates good to very good similarity between the two sEMG systems, enabling the analysis of muscle activity during functional tasks.<\/jats:p>","DOI":"10.3390\/s24185954","type":"journal-article","created":{"date-parts":[[2024,9,13]],"date-time":"2024-09-13T11:29:59Z","timestamp":1726226999000},"page":"5954","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Development of Surface EMG for Gait Analysis and Rehabilitation of Hemiparetic Patients"],"prefix":"10.3390","volume":"24","author":[{"given":"Didier","family":"Pradon","sequence":"first","affiliation":[{"name":"P\u00f4le Parasport University Hospital Raymond Poincar\u00e9, APHP, 92380 Garches, France"},{"name":"U1179 Endicap, Versailles Saint Quentin University, 78000 Versailles, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Tong","sequence":"additional","affiliation":[{"name":"U1179 Endicap, Versailles Saint Quentin University, 78000 Versailles, France"},{"name":"Kinvent, 34000 Montpellier, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0886-5936","authenticated-orcid":false,"given":"Christos","family":"Chalitsios","sequence":"additional","affiliation":[{"name":"Kinvent, 34000 Montpellier, France"},{"name":"Biomechanics Laboratory, Aristotle University of Thessaloniki, 57001 Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicolas","family":"Roche","sequence":"additional","affiliation":[{"name":"U1179 Endicap, Versailles Saint Quentin University, 78000 Versailles, France"},{"name":"Service d\u2019Explorations Fonctionnelles, University Hospital Raymond Poincar\u00e9, APHP, 92380 Garches, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,13]]},"reference":[{"key":"ref_1","unstructured":"Perry, J., and Burnfield, J.M.
