Fifteen subjects were recruited to perform a series of sudden loading tasks using three different foot postures with two levels of weight. Our results showed that sudden external loading generated the smallest impact when subjects adopted \u201cStaggered Stance\u201d. Compared with \u201cWide Stance\u201d, \u201cStaggered Stance\u201d significantly decreased the increment of trunk flexion angle, increment of L5\/S1 joint moment, and peak L5\/S1 joint anterior-posterior shear force by 21.5%, 6.5%, and 22.5%, respectively. Compared with \u201cNarrow Stance\u201d, the decreases were 15.1%, 3.2%, and 16.2% respectively. Heavier load weight resulted in larger spinal impact. The interaction effect between foot posture and magnitude of the load was not significant. The findings of this study could be used in reducing the risk of low back pain when dealing with sudden loading.<\/jats:p>","DOI":"10.1177\/1541931213571206","type":"journal-article","created":{"date-parts":[[2013,9,30]],"date-time":"2013-09-30T22:23:17Z","timestamp":1380579797000},"page":"929-933","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Trunk Kinematics under Sudden Loading Impact when Adopting Different Foot Postures"],"prefix":"10.1177","volume":"57","author":[{"given":"Jie","family":"Zhou","sequence":"first","affiliation":[{"name":"Department of Industrial and Management Systems Engineering, West Virginia University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaopeng","family":"Ning","sequence":"additional","affiliation":[{"name":"Department of Industrial and Management Systems Engineering, West Virginia University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Boyi","family":"Dai","sequence":"additional","affiliation":[{"name":"Division of Kinesiology and Health, University of Wyoming"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,9,30]]},"reference":[{"key":"bibr1-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1007\/BF00241125"},{"key":"bibr2-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1249\/00005768-199110000-00012"},{"key":"bibr3-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1993.sp019824"},{"key":"bibr4-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200006010-00012"},{"key":"bibr5-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1080\/00140130601154814"},{"key":"bibr6-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-8141(96)00023-6"},{"key":"bibr7-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1016\/S0268-0033(00)00087-5"},{"key":"bibr8-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(87)90049-2"},{"key":"bibr9-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3181e70488"},{"key":"bibr10-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1016\/S1050-6411(99)80005-4"},{"key":"bibr11-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199310001-00029"},{"key":"bibr12-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1177\/001872088903100108"},{"key":"bibr13-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2004.09.038"},{"key":"bibr14-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-198410000-00014"},{"key":"bibr15-1541931213571206","doi-asserted-by":"publisher","DOI":"10.1016\/S1050-6411(97)00006-0"},{"key":"bibr16-1541931213571206","doi-asserted-by":"crossref","unstructured":"Marras W.
