Immediate Effect of Neurodynamic Tensioner Versus Proprioceptive Neuromuscular Facilitation Stretch on Subjects with Short Hamstring Syndrome

Background: Decreased flexibility of Hamstrings has a negative impact on the posture of lumbo-pelvic region and may serve as a cause of low back pain.It is also a major contributing factor for lumbar spine disorders, hamstring strains and other sports related injuries.Aim of Study: Tocompare the effects of (NT) Neurodynamic Tensioner and (PNF) hold-relax stretching on hamstring flexibility in order toidentify the most effective intervention for short hamstring syndrome.Material and Methods: Present study conducted as Pretest -Post-test Experimental study.Participants: Forty subjects with short hamstring syndrome participated in this study.Subjects were subdivided into two matched groups; each group consisted of twenty subjects, group A who received neural tensioner in slump position; and group B who received the PNF (hold-relax) stretching.Outcome Measure: Knee extension angle (KEA) in degrees was measured using the Active Knee Extension (AKE) test with using a digital goniometer.Results: There was no significant difference in the KEA between group A and B pretreatment ( p=0.75).There was no significant difference in the KEA between group A and B post treatment (p=0.38).Conclusions: Neurodynamic tensioner and PNF (holdrelax) stretching are equally effective in increasing hamstring flexibility immediately in subjects with short hamstring syndrome.
