The aim of this research was to analyze the effect of a spinal traction system on discomfort, spinal shrinkage, and spinal sagittal alignment in assembly line workers, who are in prolonged standing conditions during a workday. A total of 16 asymptomatic males were recruited to assess spinal shrinkage, spinal sagittal alignment, and back discomfort during the workday. The measurement was carried out in two days of work, a normal day, and the other using a spinal traction device utilized in two breaks during the workday. Assembly line workers lost height significantly on both control and intervention days. No differences were found between days. No changes were found in spinal sagittal alignment on the control day. Lumbar lordosis angle increased significantly at the end of the intervention day. The use of a spinal traction device during the workday in two breaks time did not significantly reduce the spinal shrinkage of healthy workers. Lumbar lordosis angle increased significantly at the end of the spinal traction intervention day. Prospective studies would be necessary to clarify the possible benefits of the traction device.<\/jats:p>","DOI":"10.3390\/ijerph18147708","type":"journal-article","created":{"date-parts":[[2021,7,20]],"date-time":"2021-07-20T11:26:10Z","timestamp":1626780370000},"page":"7708","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Use of a Spinal Traction Device during Work Shift in Assembly Line Workers"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0879-1209","authenticated-orcid":false,"given":"Juan","family":"Rabal-Pelay","sequence":"first","affiliation":[{"name":"Department of Physical Activity and Sports Sciences, Faculty of Health Science, Universidad San Jorge, 50830 Villanueva de G\u00e1llego, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9415-7241","authenticated-orcid":false,"given":"Cristina","family":"Cimarras-Otal","sequence":"additional","affiliation":[{"name":"Department of Physical Activity and Sports Sciences, Faculty of Health Science, Universidad San Jorge, 50830 Villanueva de G\u00e1llego, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00f3nica","family":"Macia-Calvo","sequence":"additional","affiliation":[{"name":"Hospital MAZ, Avda.
