5. Study Description

Brief Summary
The current study investigates the effect of different doses of pulses ultrasound therapy on different nerve conduction parameters of the median nerve in healthy volunteering subjects.
Detailed Description
In the current study, we apply pulsed ultrasound therapy on median nerves of healthy volunteer subjects, at 1 W/cm2 10% duty cycle, 3 W/cm2 10% duty cycle, 1 W/cm2 50% duty cycle, and 3 w/cm2 50% duty cycle. Parameters of median nerve conduction study, Latency, amplitude, area, duration and forearm NCV are recorded before and after application of ultrasound therapy.
