Effect Of Nordic Hamstring Exercise And Sciatic Nerve Slider Technique Neural Mobilisation On Hamstrings Tightness In Athletes: A Randomised Clinical Trial

Abstract

BACKGROUND: The aim of Nordic exercise is to strengthen the hamstrings, glutes and core muscles.Slider is a neurodynamic manoeuvre which produces a sliding movement of the nerves in relation to their tissues. The Objective of the present study is to find out the effectiveness of Nordic Hamstring Exercise and sciatic nerve slider technique neural mobilization on hamstring tightness in relation to an athlete’s functional performance. METHODOLOGY: All subjects were recruited after meeting the inclusion and exclusion criteria. 48 participants were allotted and divided into group A,B and C. 16 in group A received Nordic Hamstring Exercise, 16 in group B received sciatic nerve Slider technique neural mobilisation and 16 in group C received Nordic Hamstring Exercises and Sciatic Nerve mobilisation for a period of 2 weeks. All the outcome measures were measured at pre and post intervention. RESULTS: In the present study, statistical significance was achieved within the three groups in sargent jump test(SJT)(p<0.05) Lower extremity functional test(LEFT)(p<0.05),Active knee extension test of right leg (AKET)(p=0.0001) along with Hand held dynamometer(HHD)for right leg. In between the groups, statistical significance was seen in between group A and B for AKET in right leg, between group A and C and B and C for AKET of left leg, between group A and C for HHD of right leg. CONCLUSION: Group C has not shown any added benefits as compared to the benefits obtained by the interventions when performed individually
