These disorders are characterized by the degeneration of motor neurons in the cerebral cortex, spinal cord, brain stem, and pyramidal tracts. Because of the rapid degradation of the muscles that comes with progressive bulbar palsy, physical therapy is an important element for patients to maintain the best quality of life possible for as long as they can. Physical therapists will exercise the muscles that are becoming the weakest, ensuring they do not begin to atrophy from not being used. MG with MuSK antibodies (MuSK-MG) is often associated with persistent bulbar involvement, including marked facial weakness and tongue muscle wasting. The extent of muscle wasting in MuSK-MG, and whether it is also found in the few acetylcholine receptor (AChR-MG) patients who have persistent bulbar involvement, is not clear. Bulbar Signs : The Bulbar muscles are those supplied by the motor nerves coming off the brain stem which control breathing, swallowing, talking and other functions of the throat.
