However, nerve behavior with neurodynamic sequences still requires in vivo research. Objective To quantify differences in median nerve (MN) stiffness measuring shear-wave velocity (SWV) with ultrasound elastography during three sequences of the ULNT1. Design Cross-sectional study. Methods MN SWV was measured in 35 asymptomatic subjects at the wrist and elbow at the initial and final position (P1) of the standard (ULNT1-STD), proximal-to-distal (ULNT1-PROX) and distal-to-proximal (ULNT1-DIST) sequences of the ULNT1. Results Significantly different increases at P1 in nerve stiffness occurred between sequences and locations (p < 0.001). At the wrist, the ULNT1-PROX produced the smallest increase (44.32% ± 44.06, SWV: 4.49 ± 0.95 m/s), the ULNT1-STD produced a larger increase (82.13% ± 45.36, SWV: 5.67 ± 0.79 m/s, p < 0.001) and the ULNT1-DIST produced the largest (92.90% ± 55.37, SWV: 5.97 ± 0.79 m/s, p < 0.001). Differences between the ULNT1-DIST and ULNT1-STD did not reach significance. At the elbow, the ULNT1-PROX showed a 119.92% ± 53.51 increase (SWV: 4.08 ± 0.84 m/s), the ULNT1-DIST a 134.84% ± 53.83 (SWV: 4.34 ± 0.77 m/s), and the ULNT1-STD a 113.30% ± 59.28 (SWV: 3.98 ± 1.04 m/s). No significant differences were found among the sequences. Conclusion The ULNT1-STD and ULNT1-DIST showed greater increases at MN stiffness at the wrist compared to the ULNT1-PROX. This supports a basis for future investigation of the mechanisms of neurodynamic testing in which emphasizing anatomical locations for improving diagnostic efficacy might be applied. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 2.2 2024 REHABILITATION 44 / 175 = 0.251 2024 Q2 T1 0.85 2024 Physical Therapy, Sports Therapy and Rehabilitation 2024 Q1 4.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Estébanez-de-Miguel, Elena Universidad de Zaragoza (orcid)0000-0002-5161-7479 Albarova-Corral, Isabel Universidad de Zaragoza (orcid)0000-0003-1292-3163 Malo-Urriés, Miguel Universidad de Zaragoza (orcid)0000-0001-9080-0543 Shacklock, Michael Montaner-Cuello, Alberto Universidad de Zaragoza (orcid)0009-0000-0252-5642 Bueno-Gracia, Elena Universidad de Zaragoza (orcid)0000-0002-0026-9224 1003 027 Universidad de Zaragoza Dpto.
