Acute Effects of Neurodynamic Sciatic Nerve Tensioning Versus Sliding on Hamstring Flexibility and Agility among Normals

Amal Baby

Abstract: Background: The nerve tension, tightness and immobility are the main causes of hamstring flexibility and hamstring injury. In presence of neural mechanosensitivity the protective muscle contraction occurs and it leads to hamstring tightness predisposing to subsequent strain injury. Nerve mobilization, evolving techniques integrates both musculoskeletal and neural structures by a "Flossing" of the nervous system to reduce pain and increase range of motion. It has two types: Tensioners and Sliders. Objectives: To compare the immediate effect of neurodynamic tensioners versus neurodynamic sliders on hamstring flexibility and agility performance applied to normal male college students. Methods: Thirty subjects having knee flexion angle of more than 20? of AKE test were selected as subjects. Consent obtained from all thirty subjects. Pretest measurements, AKE test for hamstring flexibility and Agility T test for Agility performance were measured in the dominant leg and noted. Subjects were randomly divided into two groups. Subjects in group A received Neurodynamic Tensioners and Subjects in group B received Neurodynamic Sliders. After the intervention, post test scores of AKE and Agility T test were measured and noted. Results & Discussion: Statistical tool used was student 'T' test. It was found that both neurodynamic sciatic nerve tensioners and sliders are effective in improving hamstring flexibility and agility in normal and sliders had a slightly greater improvement in flexibility and agility than tensioners. Conclusion: These data suggests that both the tensioners and sliders may be useful in increasing hamstring flexibility and agility.
