Sweating, spasm and clenching

Sweat glands are driven by the same acetylcholine signal as muscle, so the same cut stops them, and the underarm pattern is 50 Units per side. Eyelid spasm, neck spasm, strabismus and limb stiffness after a stroke are all the original uses, placed by a specialist who often works with electrical muscle guidance. Teeth grinding sits in the same family, quietening the muscle that does the damage. In each case the target is a muscle or gland that will not stop on its own.
