However, to accurately measure hamstring extensibility throughout PSLR, appropriate stabilization of the pelvis must be provided in order to minimize the possible influence of any compensatory movement in the scores reached. The main purpose of this study was to demonstrate the degree of influence of the Lumbosant\u00a9 and an assistant examiner in hamstring extensibility in healthy young adults. A secondary objective was to verify the variability of the posterior pelvic tilt movement. Hamstring muscle extensibility was measured using the traditional (only an examiner) and new (using a low-back protection support Lumbosant\u00a9 and two trained [principal and assistant] examiners) PSLR procedures. Correlation coefficients were expressed using r values, accompanying descriptors and 90% confidence intervals. Variance explained was expressed via the R2 statistic. To examine possible differences, the Mann-Whitney U-test was conducted. Additionally, Cohen\u2019s d was calculated for all results, and the magnitudes of the effect were interpreted and statistical significance set at p &lt; 0.05. A stepwise multiple regression analysis was performed to examine the relationship between scores and values. The final score that was determined with the new PSLR is significantly lower (13\u00b0 approximately) than the one obtained through the traditional procedure (75.3 \u00b1 14.4\u00b0 vs. 89.2 \u00b1 20.8\u00b0; d = \u22120.777 [moderate]). The data presented in this study suggest that the PSLR may overestimate hamstring extensibility unless lumbopelvic movement is controlled. Therefore, we recommend the use of Lumbosant\u00a9 and an auxiliary examiner to obtain more accurate hamstring extensibility scores.<\/jats:p>","DOI":"10.3390\/sym12060927","type":"journal-article","created":{"date-parts":[[2020,6,3]],"date-time":"2020-06-03T04:12:09Z","timestamp":1591157529000},"page":"927","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Straight Leg Raise Test: Influence of Lumbosant\u00a9 and Assistant Examiner in Hip, Pelvis Tilt and Lumbar Lordosis"],"prefix":"10.3390","volume":"12","author":[{"given":"Fernando","family":"Santonja-Medina","sequence":"first","affiliation":[{"name":"Department of Surgery, Pediatrics, Obstetrics and Gynecology, Faculty of Medicine, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, 30100 Murcia C.P., Spain"},{"name":"Traumatology and Orthopedic Surgery Service, Virgen de la Arrixaca University Clinical Hospital, El Palmar (Murcia), 30120 Murcia, Spain"},{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"}]},{"given":"Sara","family":"Santonja-Renedo","sequence":"additional","affiliation":[{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5903-0843","authenticated-orcid":false,"given":"Antonio","family":"Cejudo","sequence":"additional","affiliation":[{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"},{"name":"Department of Physical Activity and Sport, Faculty of Sport Sciences, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, San Javier, 30720 Murcia C.P., Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2210-7389","authenticated-orcid":false,"given":"Francisco","family":"Ayala","sequence":"additional","affiliation":[{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"},{"name":"Department of Sport Science, Sports Research Centre, Miguel Hern\u00e1ndez University of Elche, 03202 Elche (Alicante), Spain"}]},{"given":"Vicente","family":"Ferrer","sequence":"additional","affiliation":[{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"}]},{"given":"Antonio","family":"Pastor","sequence":"additional","affiliation":[{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"}]},{"given":"M\u00f3nica","family":"Collazo-Di\u00e9guez","sequence":"additional","affiliation":[{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"},{"name":"Department of Rehabilitation Sciences and Physiotherapy, Albacete University Hospital Complex, 02006 Albacete C.P., Spain"}]},{"given":"Olga","family":"Rodr\u00edguez-Ferr\u00e1n","sequence":"additional","affiliation":[{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"},{"name":"Department of Physical Activity and Sport, Faculty of Sport Sciences, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, San Javier, 30720 Murcia C.P., Spain"}]},{"given":"Pilar","family":"And\u00fajar","sequence":"additional","affiliation":[{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"},{"name":"Department of Rehabilitation Sciences and Physiotherapy, Albacete University Hospital Complex, 02006 Albacete C.P., Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1379-5151","authenticated-orcid":false,"given":"Pilar","family":"Sainz de Baranda","sequence":"additional","affiliation":[{"name":"Sports and Musculoskeletal System Research Group (RAQUIS), University of Murcia, 30100 Murcia C.P., Spain"},{"name":"Department of Physical Activity and Sport, Faculty of Sport Sciences, Regional Campus of International Excellence \u201cCampus Mare Nostrum\u201d, University of Murcia, San Javier, 30720 Murcia C.P., Spain"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"90","DOI":"10.1016\/j.gaitpost.2006.07.011","article-title":"The Effect of Simulated Hamstring Shortening on Gait in Normal Subjects","volume":"26","author":"Whitehead","year":"2007","journal-title":"Gait Posture"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Laird, R., Gilbert, J., Kent, P., and Keating, J.
