The objective of this study was to establish the repeatability and the inter-operator reproducibility of a sensors-based system (EQUISYM\u00ae) for quantifying gait asymmetries in horses.. Seven wireless IMUs were placed on the head, the withers, the pelvis, and the 4 cannon bones on three horses, by four different operators, four times on each horse, which led to a total of 48 repetitions randomly assigned. Data were collected along three consecutive days and analysed to calculate total variance, standard deviation and the variance attributable to the operator on multiple asymmetry variables. Maximal percentage of variance due to the operator (calculated out of the total variance) was 5.3% and was related to the sensor placed on the head. The results suggest a good reproducibility of IMU-based gait analysis systems for different operators repositioning the system and repeating the same measurements at a succession of time intervals. Future studies will be useful to confirm that inter-operator reproducibility remains valid in larger groups and on horses with different degrees of locomotor asymmetry.<\/jats:p>","DOI":"10.3390\/s22239533","type":"journal-article","created":{"date-parts":[[2022,12,7]],"date-time":"2022-12-07T05:50:52Z","timestamp":1670392252000},"page":"9533","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["A Pilot Study on the Inter-Operator Reproducibility of a Wireless Sensors-Based System for Quantifying Gait Asymmetries in Horses"],"prefix":"10.3390","volume":"22","author":[{"given":"Iris","family":"Timmerman","sequence":"first","affiliation":[{"name":"Ecole Nationale V\u00e9t\u00e9rinaire d\u2019Alfort, USC INRAE-ENVA 957 BPLC, CIRALE, 94700 Maisons-Alfort, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2381-7465","authenticated-orcid":false,"given":"Claire","family":"Macaire","sequence":"additional","affiliation":[{"name":"Ecole Nationale V\u00e9t\u00e9rinaire d\u2019Alfort, USC INRAE-ENVA 957 BPLC, CIRALE, 94700 Maisons-Alfort, France"},{"name":"LIM France, Labcom LIM-ENVA, 24300 Nontron, France"},{"name":"Laboratoire de BioM\u00e9canique et BioIng\u00e9nierie (UMR CNRS 7338), Centre of Excellence for Human and Animal Movement Biomechanics (CoEMoB), Universit\u00e9 de Technologie de Compi\u00e8gne (UTC), Alliance Sorbonne Universit\u00e9,  60200 Compi\u00e8gne, France"}]},{"given":"Sandrine","family":"Hanne-Poujade","sequence":"additional","affiliation":[{"name":"LIM France, Labcom LIM-ENVA, 24300 Nontron, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6367-3040","authenticated-orcid":false,"given":"L\u00e9lia","family":"Bertoni","sequence":"additional","affiliation":[{"name":"Ecole Nationale V\u00e9t\u00e9rinaire d\u2019Alfort, USC INRAE-ENVA 957 BPLC, CIRALE, 94700 Maisons-Alfort, France"}]},{"given":"Pauline","family":"Martin","sequence":"additional","affiliation":[{"name":"LIM France, Labcom LIM-ENVA, 24300 Nontron, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0440-4849","authenticated-orcid":false,"given":"Fr\u00e9d\u00e9ric","family":"Marin","sequence":"additional","affiliation":[{"name":"Laboratoire de BioM\u00e9canique et BioIng\u00e9nierie (UMR CNRS 7338), Centre of Excellence for Human and Animal Movement Biomechanics (CoEMoB), Universit\u00e9 de Technologie de Compi\u00e8gne (UTC), Alliance Sorbonne Universit\u00e9,  60200 Compi\u00e8gne, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1977-1521","authenticated-orcid":false,"given":"Henry","family":"Chateau","sequence":"additional","affiliation":[{"name":"Ecole Nationale V\u00e9t\u00e9rinaire d\u2019Alfort, USC INRAE-ENVA 957 BPLC, CIRALE, 94700 Maisons-Alfort, France"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,6]]},"reference":[{"key":"ref_1","unstructured":"Loomans, J.B.A. (2008).
