The compound muscle action potential (CMAP) is defined as the summated muscle fiber action potentials recorded from a surface electrode overlying a muscle after stimulation of the corresponding motor nerve fibers. It serves as a fundamental waveform in clinical neurography, commonly used to assess neuromuscular function.
This parameter is commonly measured in nerve conduction studies that many individuals with CMT routinely undergo.
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.
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.
CMT-SORD is a newly discovered CMT subtype driven by toxic sorbitol accumulation. This article explains how "SORD" works, why this subtype is different, and how it led to the fastest-moving therapeutic program in CMT history.
