A HFF of 500hz on a sensory NCS would cause the onset latency to:

Answer 1

A HFF of 500Hz on a sensory NCS would cause the onset latency to decrease compared to lower frequencies.

Step-by-step explanation:

A HFF of 500Hz on a sensory NCS (nerve conduction study) would cause the onset latency to be shorter compared to a lower frequency. Here's why:

1. The higher the frequency, the shorter the wavelength.
2. Shorter wavelengths can stimulate sensory receptors more easily by producing more frequent action potentials.
3. As a result, the nerve conduction velocity is faster for higher frequencies, leading to a shorter onset latency.

Therefore, a HFF of 500Hz would cause the onset latency to decrease compared to lower frequencies.
