Is it advisable to do exercise when affected by Myasthenia Gravis? Which activities would you suggest and how intense should they be?

Exercise and Myasthenia Gravis: Recommendations and Intensity

Myasthenia Gravis (MG) is a chronic autoimmune neuromuscular disorder that causes muscle weakness and fatigue. It primarily affects the voluntary muscles, including those involved in movement and breathing. While exercise is generally beneficial for overall health and well-being, individuals with MG need to approach it with caution and follow specific guidelines to avoid exacerbating their symptoms.

Benefits of Exercise for Myasthenia Gravis

Engaging in regular exercise can offer several benefits for individuals with Myasthenia Gravis:

• Improved muscle strength: Appropriate exercise can help strengthen muscles and improve their endurance, potentially reducing weakness and fatigue.


• Enhanced cardiovascular health: Aerobic exercises, when tolerated, can improve heart and lung function, promoting overall cardiovascular health.


• Mood and mental well-being: Exercise has been shown to boost mood, reduce stress, and improve mental well-being, which can be particularly beneficial for individuals with chronic conditions like MG.


• Weight management: Regular physical activity can help maintain a healthy weight, which is important for managing MG symptoms and overall health.

Exercise Recommendations for Myasthenia Gravis

While exercise can be beneficial, it is crucial for individuals with MG to consult with their healthcare provider before starting or modifying an exercise routine. The following recommendations are generally suggested:

• Individualized approach: Each person with MG may have different limitations and capabilities, so it is important to tailor the exercise program to their specific needs and abilities.


• Low-impact activities: Opt for exercises that are gentle on the joints and muscles, such as walking, swimming, cycling, or using an elliptical machine. These activities minimize strain on the muscles while providing cardiovascular benefits.


• Warm-up and cool-down: Prior to exercise, it is essential to warm up the muscles with gentle stretching or range-of-motion exercises. Similarly, cooling down with stretches after exercise can help prevent muscle stiffness and soreness.


• Rest and pacing: Individuals with MG should listen to their bodies and take breaks or rest when needed. Pacing oneself during exercise and avoiding overexertion is crucial to prevent excessive fatigue and muscle weakness.


• Monitoring symptoms: Pay close attention to any changes in symptoms during or after exercise. If weakness or fatigue worsens, it may be necessary to modify the exercise routine or intensity.


• Assistance and supervision: Depending on the severity of MG symptoms, exercising with a partner or under the supervision of a healthcare professional may be advisable to ensure safety and provide assistance if needed.

Exercise Intensity for Myasthenia Gravis

The intensity of exercise for individuals with MG should be carefully managed to prevent overexertion and worsening of symptoms. The Borg Rating of Perceived Exertion (RPE) scale can be a useful tool to gauge exercise intensity. It is a subjective measure of how hard an individual feels they are working during physical activity. The recommended RPE range for individuals with MG is typically between 11 and 14 on a scale of 6 to 20, where 6 represents no exertion and 20 represents maximal exertion.

It is important to note that the appropriate exercise intensity may vary depending on the individual's overall health, disease severity, and current symptoms. Therefore, it is crucial to work closely with a healthcare professional or physical therapist who can provide personalized guidance and help determine the most suitable exercise intensity.
