The aim of this study was to investigate the capacity of cervical contralateral lateral flexion to produce differential biomechanical behaviour of the median nerve at the wrist (mechanical specificity) in relation to the adjacent muscle (flexor digitorum superficialis) at different ranges of upper limb neurodynamic test 1 in cadavers. Material and methods: A cross-sectional study was carried out. In fresh frozen cadavers, with microstrain devices and Vernier calipers, strain and excursion in the median nerve and flexor digitorum superficialis muscle were measured during cervical contralateral lateral flexion at 0°, 30°, 60° and 90° of elbow flexion of the upper limb neurodynamic test 1. Results: The cervical movement resulted in proximal excursion and significant changes in strain in the median nerve at 0°, 30° and 60° of elbow flexion during the upper limb neurodynamic test 1 (p < 0.05). In contrast, the structural differentiation manoeuvre did not affect the strain nor the excursion in the muscle at any position of the elbow (p > 0.05). Conclusion: Adding CCLF to each ULNT1 median elbow angle increased strain and created proximal excursion of the median nerve at the wrist. Neck movement produced no changes in strain nor excursion of the flexor digitorum superficialis. This study adds to evidence that, in certain circumstances, neck movement may be used in differentiation of nerve and muscle disorders in the wrist. 000165676 540__ $$9info:eu-repo/semantics/closedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000165676 590__ $$a2.52$$b2020 000165676 591__ $$aREHABILITATION$$b27 / 68 = 0.397$$c2020$$dQ2$$eT2 000165676 592__ $$a0.87$$b2020 000165676 593__ $$aPhysical Therapy, Sports Therapy and Rehabilitation$$c2020$$dQ1 000165676 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000165676 700__ $$aPérez-Bellmunt, A. 000165676 700__ $$0(orcid)0000-0002-5161-7479$$aEstébanez-de-Miguel, E.$$uUniversidad de Zaragoza 000165676 700__ $$aLópez-de-Celis, C. 000165676 700__ $$0(orcid)0000-0003-0328-2309$$aCaudevilla-Polo, S.$$uUniversidad de Zaragoza 000165676 700__ $$aShacklock, M. 000165676 700__ $$aGonzález-Rueda, V. 000165676 7102_ $$11006$$2413$$aUniversidad de Zaragoza$$bDpto.
