This randomized controlled trial examined the effects of neurodynamic mobilization techniques on sciatic nerve and hamstring stiffness in 20 physically active individuals. The study found that neurodynamic flossing at maximal intensity significantly reduced sciatic nerve stiffness compared to static stretching, with a notable condition × time interaction (p < 0.001).
Key findings
- Flossing at maximal intensity significantly decreased sciatic nerve stiffness (p < 0.001).
- Biceps femoris shear wave velocity decreased over time (p = 0.004) regardless of the condition.
- Flexibility improved significantly after all stretching interventions (p < 0.001).
- Maximum voluntary isometric contraction (MVIC) decreased across all conditions (p = 0.009).
Why it matters
Understanding the effects of different stretching techniques on nerve and muscle stiffness can inform rehabilitation practices. Prioritizing neurodynamic flossing may enhance outcomes for patients requiring improved neural mobility.
