Changes in Hamstring Range of Motion After Neurodynamic Sciatic Sliders: A Critically Appraised Topic.

Clinical Scenario: Hamstring tightness is a common condition leading to dysfunctional or restricted movement that is often treated with stretching. Neurodynamics has been proposed as an alternative to stretching by targeting the neural system rather than muscle tissue. Focused Clinical Question: In an active population, what is the effect of using neurodynamic sliders compared with stretching on traditional measures of range of motion (ROM)? Summary of Key Findings: The authors of a well-designed study found that neurodynamic sliders were more effective than static stretching, while the authors of 2 less-well-designed studies reported no difference with static stretching or that proprioceptive neuromuscular facilitation stretching was more effective than neurodynamic sliders. Clinical Bottom Line: Evidence exists to support the use of neurodynamic sliders to increase measures of hamstring ROM in patients who present with limited hamstring flexibility; however, the effectiveness of neurodynamic sliders compared with traditional stretching is inconclusive. Strength of Recommendation: Grade B evidence exists that neurodynamic sliders perform as well as traditional stretching techniques at increasing measures of hamstring ROM in patients with limited hamstring flexibility.
