METHODS: Twelve male volunteers with flat-back syndrome (global angle &lt; 20 degrees) and 12 male volunteers with normal spinal alignment (global angle between 20 degrees and 30 degrees) were enrolled. An accelerator was attached to the third lumbar spine and the sway of each participant\u2019s trunk was measured during stair climbing. RESULT: Participants with flat-back syndrome showed significant differences in vector, anteroposterior sway, and vertical sway of the trunk during stair climbing (p&lt; 0.05). However, mediolateral sway of the trunk and gait time did not significantly differ between groups (p&gt; 0.05). CONCLUSION: Our findings can be used as baseline data for prevention of back pain. Furthermore, increased trunk sway can cause increased energy usage, leading to inefficient gait. Further research is needed to prevent this problem.<\/jats:p>","DOI":"10.3233\/thc-202668","type":"journal-article","created":{"date-parts":[[2021,5,18]],"date-time":"2021-05-18T13:47:44Z","timestamp":1621345664000},"page":"483-489","source":"Crossref","is-referenced-by-count":2,"title":["Effects of lower trunk movement in flat-back syndrome during stair climbing: A technical note"],"prefix":"10.1177","volume":"30","author":[{"given":"Yaoyao","family":"Liu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Won-Gyu","family":"Yoo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/THC-202668_ref1","first-page":"905","article-title":"Frontal and sagittal plane analyses of the stair climbing task in healthy adults aged over 40 years: what are the challenges compared to level walking","volume":"18","author":"Nedeau","year":"2003","journal-title":"Clinical Biomechanics"},{"key":"10.3233\/THC-202668_ref2","doi-asserted-by":"crossref","first-page":"159","DOI":"10.1016\/j.gaitpost.2016.06.030","article-title":"A review of stairway falls and stair negotiation: lessons learned and future needs to reduce injury","volume":"49","author":"Jacobs","year":"2016","journal-title":"Gait Post"},{"key":"10.3233\/THC-202668_ref4","doi-asserted-by":"crossref","first-page":"340","DOI":"10.1016\/j.jbiomech.2014.11.019","article-title":"Muscle coordination of support, progression and balance duringstair ambulation","volume":"48","author":"Lin","year":"2015","journal-title":"Journal of Biomechanics"},{"issue":"5","key":"10.3233\/THC-202668_ref5","first-page":"683","article-title":"Perceiving affordances: visual guidance of stair climbing","volume":"10","author":"Warren","year":"1984","journal-title":"Journal of Experimental Psychology: Human Perception and Performance."},{"key":"10.3233\/THC-202668_ref6","doi-asserted-by":"crossref","first-page":"538","DOI":"10.1016\/j.eurger.2016.04.003","article-title":"Effects of differences in visual acuity on gait time and trunk acceleration when older women negotitate stairs","volume":"7","author":"Shin","year":"2016","journal-title":"European Geriatric Aledicine."},{"issue":"2","key":"10.3233\/THC-202668_ref7","doi-asserted-by":"crossref","first-page":"203","DOI":"10.1016\/j.clinbiomech.2006.09.010","article-title":"Hip, knee, ankle kinematics and kinetics during stair ascent and descent in healthy young individuals","volume":"22","author":"Protopapadaki","year":"2007","journal-title":"Clin Biomech."},{"key":"10.3233\/THC-202668_ref9","doi-asserted-by":"crossref","first-page":"296","DOI":"10.1016\/j.gaitpost.2018.05.006","article-title":"Continuous lumbar spine rhythms during level walking, stair climbing and trunk flexion in people with and without lumbar disc herniation","volume":"63","author":"Kuai","year":"2018","journal-title":"Gait & Posture."},{"key":"10.3233\/THC-202668_ref12","unstructured":"Doherty JH.
