Brief Summary:
During this pilot study, the investigators will examine the effects of whole-body electrical muscle stimulation exercise (WB-EMS Exercise) on neuromuscular junction (NMJ) transmission and fatigability in adults with Generalized Myasthenia Gravis (gMG). The investigators will also test whether a relationship exists between NMJ transmission dysfunction and fatigability in gMG, which has long been presumed but never directly assessed. Participants will undergo clinical and electrophysiologic testing before and after the WB-EMS Exercise intervention. The WB-EMS Exercise intervention will be delivered 2 times per week for 4 weeks. Long-term follow up is optional. The hypotheses are (a) that the WB-EMS exercise will improve fatigability and NMJ transmission, and (b) that NMJ transmission dysfunction is related to fatigability.
Detailed Description:
During this pilot study, the investigators will examine the effects of a novel paradigm, whole-body electrical muscle stimulation exercise (WB-EMS Exercise), on neuromuscular junction (NMJ) transmission and fatigability in adults with Generalized Myasthenia Gravis (gMG). The investigators will also test whether a relationship exists between NMJ transmission dysfunction and fatigability in gMG, which has long been presumed but never directly assessed. The investigators will use single fiber electromyography (SFEMG) to capture pre- and post-treatment jitter, which measures NMJ transmission variability. The investigators will use decomposition electromyography and clinical measures to assess pre- and posttreatment fatigability of motor units and muscles. and associate these with baseline values for NMJ transmission to determine the relationship between these variables. At the conclusion of the study, expected outcomes include: (1) preliminary data regarding the efficacy of WB-EMS Exercise to address fatigability, (2) an indication of whether this type of exercise may promote NMJ remodeling, and (3) clarification of mechanistic connections between NMJ transmission and fatigability. These findings will provide new insights into mechanisms of fatigability and responses to exercise in gMG. The long-term goal is to define the effects of exercise on gMG pathophysiology and identify effective and tolerable modes of exercise that can be recommended to manage and prevent gMG-related fatigue.
