These new methods use motion capture data of the lower limb joints (e.g., joint and body segment angular position and\/or velocity, or joint center locations) and include: (1) Regions of Deviation (ROD) analysis, (2) complexity and variability of phase portraits, and (3) multivariate shape-alignment and decomposition. We provide example demonstrations of these techniques using data from infants, typical and atypically developing children, simulated injuries of a knee or ankle, and wheelchair propulsion.<\/jats:p>","DOI":"10.3390\/sym2021135","type":"journal-article","created":{"date-parts":[[2010,6,14]],"date-time":"2010-06-14T11:40:21Z","timestamp":1276515621000},"page":"1135-1155","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["A Review of New Analytic Techniques for Quantifying Symmetry in Locomotion"],"prefix":"10.3390","volume":"2","author":[{"given":"Elizabeth T.","family":"Hsiao-Wecksler","sequence":"first","affiliation":[{"name":"Department of Mechanical Science and Engineering, University of Illinois at Urbana-Champaign, IL, USA"}]},{"given":"John D.","family":"Polk","sequence":"additional","affiliation":[{"name":"Department of Anthropology, University of Illinois at Urbana-Champaign, IL, USA"},{"name":"Department of Surgery, University of Illinois at Urbana-Champaign, IL, USA"}]},{"given":"Karl S.","family":"Rosengren","sequence":"additional","affiliation":[{"name":"Department of Psychology, Northwestern University, IL, USA"}]},{"given":"Jacob J.","family":"Sosnoff","sequence":"additional","affiliation":[{"name":"Department of Kinesiology & Community Health, University of Illinois at Urbana-Champaign, IL, USA"}]},{"given":"Sungjin","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Psychology, University of Illinois at Urbana-Champaign, IL, USA"}]}],"member":"1968","published-online":{"date-parts":[[2010,6,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1147","DOI":"10.1016\/S0736-0266(01)00032-8","article-title":"Gait analysis after total hip arthroplasty with leg-length equalization in women with unilateral congenital complete dislocation of the hip-comparison with untreated patients","volume":"19","author":"Lai","year":"2001","journal-title":"J.
