EMG-Guided Botox® Injections
Using electromyography equipment (measuring electrical activity in the muscle) to pinpoint the exact point of nerve disorder, the neurologist may inject Botox® into the muscle. Botox is a very powerful chemical originally derived from a bacteria which can result in very focal, sustained relaxation of muscles. As such, Botox has been found to be very useful for neurologic disorders that are characterized by sustained involuntary contractions of muscles. Some conditions that Botox injections are used for are torticollis (twisting of the neck), writer's cramp (involuntary contractions of the fingers when writing) and for muscle stiffness secondary to strokes and multiple sclerosis.
