G71.0

Clinical Causes: Genetic mutations: Most forms are inherited due to mutations in specific genes responsible for muscle proteins. Family history: A previous family member with muscular dystrophy increases the risk of developing the disorder. X-linked inheritance: Some types, like Duchenne and Becker muscular dystrophy, are linked to the X chromosome and primarily affect males.

Key Symptoms: Muscle weakness: Often begins in the hips, thighs, and shoulders. Progressive muscle wasting: Loss of muscle mass over time. Difficulty with movements: Such as walking, standing, or climbing stairs. Frequent falls: Especially in the early stages. Enlarged calf muscles: Due to muscle tissue replacement by fat and connective tissue. Limited range of motion: Because of joint contractures. Other signs: Fatigue, muscle cramps, and, in some cases, difficulty breathing or swallowing.

Diagnosis Path: Physical examination: Assessing muscle strength and joint flexibility. Genetic testing: Identifying specific gene mutations associated with the type of muscular dystrophy. Electromyography (EMG): Measuring electrical activity of muscles. Muscle biopsy: Examining muscle tissue to look for characteristic changes. Blood tests: Elevated levels of creatine kinase (CK) can indicate muscle damage. Imaging studies: MRI scans can visualize muscle degeneration.

Treatment Protocols: Physical therapy: To maintain muscle strength and prevent contractures. Medications: Corticosteroids can slow muscle degeneration in some types. Assistive devices: Braces, wheelchairs, and other tools to aid mobility. Surgical intervention: For contractures or scoliosis correction. Respiratory support: Breathing assistance if involved muscles weaken. Cardiac care: Monitoring and managing heart conditions associated with certain forms.
