Acute Effects of Neurodynamics on Strength and Endurance in Athletes
20. juli 2026 opdateret af: Tommy Wyatt, High Point University
Acute Effects of Neurodynamics on Strength and Endurance in Athletes: A Randomized Control Trial
This study explores the acute effects of neurodynamics, an intervention commonly used by physical therapist to improve nerve mobility and decrease pain, on the strength and muscular endurance in the athletic population.
This study aims to find if these interventions can maintain or promote strength and endurance in the hamstrings.
The studies results will help physical therapist better prescribe exercise and hands-on treatment for hamstring and sciatic nerve related conditions and injuries.

Våben og indgreb
Deltagergruppe / Arm |
Intervention / Behandling |
|---|---|
|
Aktiv komparator: Sliders
Manually applying slider technique of neurodynamics.
|
Mobility of a nerve, by placing tension on one end of the nerve and slacking (removing) tension off the other side of the nerve, through a full range of motion.
|
|
Aktiv komparator: Tensioners
Manually applied tensioner, neurodynamic technique
|
Loading the nerve, by placing tension on both ends of the nerve, isometrically at end range of motion.
|
|
Eksperimentel: Mechanically Loaded Neurodynamics
Externally loaded neurodynamic intervention in the slider technique.
|
Placing tension on one end of the nerve while taking the tension off the other end, under external load of an elastic resistance band.
Elastic resistance band was used to provide submaximal resistance during the mechanically loaded neurodynamic intervention.
