The effects of neurodynamic straight leg raise treatment duration on range of hip flexion and protective muscle activity at P1.

Study Design: Randomized, single blind, same subject crossover trial.

Objectives: To compare the effects of two neurodynamic treatment doses on range of hip flexion (ROM HF) and electromyographic (EMG) activity of semitendinosus, at first onset of pain (P1).

Methods: A total of 26 healthy participants without low back or leg pain received each treatment in a random order with at least 48 hours between sessions.
