Proximal nerve stimulation
F wave
In neuroscience, an F wave is the second of two voltage changes observed after electrical stimulation is applied to the skin surface above the distal region of a nerve. F waves are often used to measure nerve conduction velocity, and are particularly useful for evaluating conduction problems in the proximal region of nerves (i.e. , portions of nerves near the spinal cord). It's called F wave because it was initially recorded in the foot muscles.
