Neurodynamic sliding versus PNF stretching on hamstring flexibility in collegiate students: A comparative study

Abstract

Background: Muscular flexibility is an important aspect of normal human function. Limited flexibility has been shown to predispose a person to several musculoskeletal overuse injuries and significantly affect a person’s level of function. Objective of the study was to compare the effectiveness of PNF (hold-relax) and Neurodynamic sliding technique for improving hamstring flexibility. Materials and Methods: 60 participants with hamstring tightness were allocated into two groups (30 participants in each group). The outcome measure used was AKE test. Subjects of group A were treated with PNF hold relax stretching, whereas the subjects of group B were treated with Neurodynamic sliding technique. For both experimental groups, the technique was performed three times a week for a total training period of four weeks. Results: The results demonstrated significant improvement in hamstring flexibility for subjects of group A when compared with those of group B (P = 0.01) at the end of four weeks. Conclusion: Although the study supports the experimental hypothesis that PNF (Hold-Relax) stretching technique is more effective than Neurodynamic sliding technique for improving hamstring flexibility.
