Effect of Neurodynamic Sliding and Dynamic Range of Motion Training on the Flexibility of Hamstring Muscle: A Comparative study

BACKGROUND: Muscular flexibility is an important aspect of normal human function. Decreased flexibility of the hamstring muscle predisposes to musculoskeletal overuse injuries commonly seen in sports activities and significantly affects the person’s functional level. AIM OF THE STUDY: To compare the effect of Neurodynamic sliding and Dynamic ROM on the hamstring muscle flexibility. OBJECTIVES: 1. Determine the effect of dynamic ROM training in the decreased hamstring flexibility in the young male subjects. 2. Determine the effect of Neurodynamic sliding decreased hamstring flexibility in the young male subjects. MATERIALS AND METHODS: 30 subjects with hamstring tightness were allocated into two groups. The outcome was measured by using AKE test and sit and reach test. Group I subjects were treated with Neurodynamic sliding whereas group II subjects were treated with Dynamic range of motion exercises. For both groups the technique was performed 5 sessions a week for total period of 6 weeks. RESULTS: The results demonstrated that significant improvement in hamstring flexibility for Group I subject when compared with Group II at the end of six weeks. CONCLUSION: The study suggested that neurodynamic sliding technique is more effective than dynamic range of motion for improving hamstring flexibility
