Muscle disorders are conditions that affect the strength, function, and control of muscles in the body. These disorders can result from genetic factors, injuries, infections, or autoimmune diseases. Common types include muscular dystrophy, which is a group of inherited disorders causing muscle weakness, and myopathy, which refers to diseases that directly affect muscle tissue. Symptoms of muscle disorders may include weakness, cramps, stiffness, and difficulty with movement. Diagnosis often involves physical examinations, blood tests, and imaging studies. Treatment options vary and may include physical therapy, medications, or lifestyle changes to help manage symptoms and improve quality of life.
