Background: The thermal and non-thermal effects of ultrasound has been used in physiotherapy of low back pain for a long time. The purpose of this study was to investigate the thermal and non-thermal effects of applying therapeutic ultrasound on the spinal mixed nerves (S1 – S2) of para-vertebral regions on the Parameters of H reflex of triceps surae muscles.<br>
<strong>Materials and methods: </strong>Fourteen healthy women between 20 to 30 years old were participated in 3 sessions of this experiment:<br>
Each subject voluntarily shared in 3 sessions of:<br>
1. Continuos ultrasound (intensity: 1.5 w/cm2, for 5 minutes)<br>
2. Pulsed ultrasound (intensity: 1 w/cm2, for 5 minutes)<br>
3. Placebo ultrasound for 5 minutes)<br>
At each session 5 maximal, H reflexes and 3-M waves were recorded before (T0), immediately after (T1) and 5 minutes after (T5) applying the ultrasound.<br>
Results: Statistical measurements showed no significant differences in latency and amplitude of H reflex and H/M ratio at T0, T1 and T5 recordings between the three ultrasound groups.<br>
Conclusion: This study showed that the thermal and non-thermal properties of ultrasound have no effect on motoneurone pool excitability and conduction through the spinal roots.<br>
