F-wave latency is the time it takes for an electrical signal to travel from a stimulation point along a motor nerve all the way to the spinal cord and back to the muscle. Because it covers the full length of the nerve, it is one of the most sensitive readings in a nerve conduction study, able to reveal slowing that shorter measurements miss. In CMT, F-wave latency is often prolonged, and it can even be absent, reflecting how far along the nerve the disease reaches.
When Medicine Lost Its Compass
Evidence failed not because it was wrong, but because it was weaponized. I lived the downstream effects of that failure for more than a decade. This is what happens when medicine forgets that data always ends in a human being.
