A three-layer artificial neural network model was developed to simulate and predict an indentation curve of human spine, characterized with the depth of lumbar lordosis and four inclination angles: cervicothoracic, thoracolumbar, lumbosacral and the back-hip (\u03b2). By comparing the spinal indentation curves described by the optimal evaluation parameters (depth of lumbar lordosis, cervicothoracic, thoracolumbar and lumbosacral), a better design of five-zone spring mattresses was obtained for individuals to have an effective support to the main part of the body. Using such approach, an operating process was further introduced, in which appropriate stiffness proportions were proposed to design mattress for the normal body types of Chinese young women. Finally, case studies were undertaken, which show that the method developed is feasible and practical.<\/jats:p>","DOI":"10.1177\/0954411914547552","type":"journal-article","created":{"date-parts":[[2014,8,22]],"date-time":"2014-08-22T23:22:37Z","timestamp":1408749757000},"page":"787-799","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Predict human body indentation lying on a spring mattress using a neural network approach"],"prefix":"10.1177","volume":"228","author":[{"given":"Shilu","family":"Zhong","sequence":"first","affiliation":[{"name":"College of Furniture and Industrial Design, Nanjing Forestry University, Nanjing, China"},{"name":"School of Engineering, University of Liverpool, Liverpool, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liming","family":"Shen","sequence":"additional","affiliation":[{"name":"College of Furniture and Industrial Design, Nanjing Forestry University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lijuan","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Furniture and Industrial Design, Nanjing Forestry University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongwei","family":"Guan","sequence":"additional","affiliation":[{"name":"School of Engineering, University of Liverpool, Liverpool, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2014,8,22]]},"reference":[{"key":"bibr1-0954411914547552","volume-title":"Back and bed: ergonomic aspects of sleeping","author":"Haex B","year":"2005"},{"key":"bibr2-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1016\/j.ergon.2006.07.007"},{"key":"bibr3-0954411914547552","first-page":"244","volume":"16","author":"Addison R","year":"1986","journal-title":"J Sleep Res"},{"issue":"6","key":"bibr4-0954411914547552","first-page":"507","volume":"16","author":"Moody P","year":"2004","journal-title":"Dermatol Nurs"},{"key":"bibr5-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1067\/mmt.2002.121410"},{"key":"bibr6-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3181695d3b"},{"key":"bibr7-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(93)90099-Z"},{"key":"bibr8-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-6870(97)00069-0"},{"key":"bibr9-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1016\/S0897-1897(00)80013-0"},{"key":"bibr10-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1111\/j.1742-481X.2011.00814.x"},{"key":"bibr11-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-6870(00)00013-2"},{"key":"bibr12-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1016\/j.apergo.2006.11.002"},{"key":"bibr13-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1016\/j.apergo.2007.04.002"},{"key":"bibr14-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-6870(97)00023-9"},{"key":"bibr15-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1016\/j.apergo.2011.06.012"},{"key":"bibr16-0954411914547552","doi-asserted-by":"publisher","DOI":"10.1080\/09291010903557187"},{"key":"bibr17-0954411914547552","volume-title":"J Biomech","author":"Haex B"},{"key":"bibr18-0954411914547552","first-page":"107","volume-title":"European Union \u2013 challenges and perspectives for the wood-processing industry.
