Objective – To analyze the neural mechanosensitivity influence in the knee extension mobility through the hamstrings flexibility test and slump test by goniometry means. Methods – Nineteen subjects were bilaterally assessment (38 lower limbs) with slump test for neural mechanosensitivity and hamstrings flexibility test by goniometer. In agreement with the slump test the lower limbs were divided in 2 groups: GSP (positive slump, n = 28) e GSN (negative slump, n = 10). After the groups formation the subjects were assessment by hamstrings flexibility test with dorsiflexion and plantar flexion. The knee range of motion (ROM) was assessment. Results – The results of the slump test show significant increase in the knee ROM post neck extension in the GSP (t=10.56; p<0,0001) and modification of knee ROM was not evidenced during the same test in the GSN (t=0.000; p=0,5). The results of the hamstrings flexibility test in the GSP show significant increase in knee ROM with plantar flexion ankle when compared with dorsiflexion (t=8.911; p<0,0001). In the GSN, modification of knee ROM was not evidenced during the same test (t=1.470; p=0.08). Conclusion – Our results suggest that ankle dorsiflexion in subjects with neural mechanosensitivity decrease detected by slump test it can influence in the knee extension ROM during the hamstrings flexibility test.
