Investigation of the Effects of Proprioceptive Neuromuscular Facilitation Exercises in Patients With Myasthenia Gravis

The goal of this clinical trial is to investigate of the effects of proprioceptive neuromuscular facilitation exercises on fatigue, muscle strength and functional parameters in patient with Myasthenia Gravis. The main questions it aims to answer are: * Do proprioceptive neuromuscular facilitation exercises reduce fatigue in patients with Myasthenia Gravis? * Do proprioceptive neuromuscular facilitation exercises increase muscle strength in patients with Myasthenia Gravis? * Do proprioceptive neuromuscular facilitation exercises improve functional parameters in patients with Myasthenia Gravis? * How well can patients with Myasthenia Gravis tolerate proprioceptive neuromuscular facilitation exercises? Participants will be divided into 2 groups as control group and exercise group with block randomization method. In this single-blind randomized controlled study, the participants in the control group will be placed on a waiting list without any intervention during the 6-week study period and at the end of the study, the interventions applied to the exercise group will be applied exactly the same. Proprioceptive neuromuscular facilitation exercises will be applied to the exercise group 3 days a week, 1 hour a day for 6 weeks. Individuals will be evaluated at the beginning and at the end of the study. Researchers will compare exercise and control group to see if there are effects of proprioceptive neuromuscular exercises patients with Myasthenia Gravis.
