EMG - Charcot-Marie-Tooth Disease

EMG - Charcot-Marie-Tooth Disease | Experts in CMT

The acronym for Electromyograph. Electromyography is a minimally invasive diagnostic study that measures electrical activity produced in a muscle in response to stimulation by a nerve. The electrical activity is analyzed while the muscle is at rest, slightly contracted, and fully contracted. The procedure typically involves inserting a fine needle into the target muscle to capture the electrical signals, which are displayed on a screen in the form of waves and may also be heard through an audio amplifier.

In CMT, this test is often performed with a nerve conduction study (NCS).

A Name That Does Too Much Work

Jean-Martin Charcot's name appears throughout medicine, but nowhere does it create more confusion than in the foot. Learn why the CMT foot and Charcot neuroarthropathy, also known as Charcot foot, share a name yet differ in how they develop, appear, and are managed.

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.

Error 404: Gene Not Found

CMT genetic testing often fails to identify the cause of the disease, even when comprehensive panels are used. Here, we discuss why this happens, what genetic tests can and cannot do, and why a negative result still matters.
