Effect of Different Ultrasound Doses on Median Nerve Conduction Parameters

September 5, 2023 updated by: Amr Saadeldeen Shalaby, Cairo University

Effect of Non-thermal Parameters of Ultrasound on Median Motor Nerve Conduction Velocity.

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.
