To increase nerve conduction velocity while using ultrasound, which wattage would you use?

Explanation:
Nerve conduction velocity rises as tissue temperature increases, and ultrasound can produce that heating when used continuously. The amount of heating depends on the energy delivered per area (watt density); higher energy yields more heating, up to safety limits. To maximize the heating and the resulting increase in conduction velocity, choose the highest safe watt density among the options, which is 3 W/cm^2. The lower watt densities would heat the tissue less and thus produce a smaller change in conduction velocity. Always stay within safety guidelines and monitor the patient’s response.
