Methods that generate detailed gait data for clinical use are typically logistically constrained to a formal gait laboratory setting. This has led to an interest in portable analysis systems for near clinical or community-based assessments. The following study assessed with the wearable accelerometer\/gyroscopic, gait analysis system (LEGSYS+TM) and the standard of static motion capture camera (MOCAP) analysis during a treadmill walk at three different walking speeds in healthy participants (n = 15). To compare each speed, 20 strides were selected from the MOCAP data and compared with the LEGSYS+ strides at the same time point. Both scatter and bland-Altman plots with accompanying linear regression analysis for each of the parameters. Each stride parameter showed minimal or a consistent difference between the LEGSYS+ and MOCAP, with the phase parameters showing inconsistencies between the systems. Overall, LEGSYS+ stride parameters can be used in the clinical setting, with the utility of phase parameters needing to be taken with caution.<\/jats:p>","DOI":"10.3390\/s23010537","type":"journal-article","created":{"date-parts":[[2023,1,4]],"date-time":"2023-01-04T03:27:44Z","timestamp":1672802864000},"page":"537","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Comparison of a Wearable Accelerometer\/Gyroscopic, Portable Gait Analysis System (LEGSYS+TM) to the Laboratory Standard of Static Motion Capture Camera Analysis"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1978-782X","authenticated-orcid":false,"given":"Ryan","family":"Homes","sequence":"first","affiliation":[{"name":"School of Biomedical Sciences, The University of Queensland, Brisbane, QLD 4067, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Devon","family":"Clark","sequence":"additional","affiliation":[{"name":"School of Biomedical Sciences, The University of Queensland, Brisbane, QLD 4067, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sina","family":"Moridzadeh","sequence":"additional","affiliation":[{"name":"School of Biomedical Sciences, The University of Queensland, Brisbane, QLD 4067, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danijel","family":"Tosovic","sequence":"additional","affiliation":[{"name":"School of Biomedical Sciences, The University of Queensland, Brisbane, QLD 4067, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9658-2388","authenticated-orcid":false,"given":"Wolbert","family":"Van den Hoorn","sequence":"additional","affiliation":[{"name":"School of Health and Rehabilitation Sciences, The University of Queensland, Brisbane, QLD 4072, Australia"},{"name":"ARC ITTC Joint Biomechanics, Queensland Unit for Advanced Shoulder Research, Movement Neuroscience Group, Injury Prevention Group, Exercise & Movement Science, School of Exercise and Nutrition Sciences, Queensland University of Technology, Brisbane, QLD 4067, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kylie","family":"Tucker","sequence":"additional","affiliation":[{"name":"School of Biomedical Sciences, The University of Queensland, Brisbane, QLD 4067, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2115-6306","authenticated-orcid":false,"given":"Mark","family":"Midwinter","sequence":"additional","affiliation":[{"name":"School of Biomedical Sciences, The University of Queensland, Brisbane, QLD 4067, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"238","DOI":"10.3109\/09593985.2011.601804","article-title":"Investigation into the reliability and validity of the measurement of elderly people\u2019s clinical walking speed: A systematic review","volume":"28","author":"Rydwik","year":"2012","journal-title":"Physiother Theory Pract."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"434","DOI":"10.4104\/pcrj.2011.00082","article-title":"Measuring walking speed in COPD: Test-retest reliability of the 30-metre walk test and comparison with the 6-minute walk test","volume":"20","author":"Andersson","year":"2011","journal-title":"Prim.
