Muscle disorders are a group of diseases and disorders that affect the human muscle system. They can be inherited and are often progressive, leading to physical disability and frequently reduced life expectancy. Muscle disorders can cause weakness, pain, loss of muscle tissue, and paralysis. They can be primary muscle diseases, which are the result of direct abnormalities of the muscles, or they can be traced as symptoms or manifestations of disorders of the nervous system or other systems.

What You'll Learn
Muscle disorders can be inherited
Muscle disorders are diseases and disorders that affect the human muscle system. They can cause weakness, pain, paralysis and loss of muscle tissue.
There are several types of muscular dystrophy, each affecting different muscles and causing varying levels of disability. Some types may also affect the heart and respiratory muscles, leading to life-threatening complications. While there is currently no cure for muscular dystrophy, treatments can help manage the symptoms and improve quality of life.
Myotonic dystrophy is another example of an inherited muscle disorder. It is characterised by prolonged muscle spasms and weakness, particularly in the hands and face. The disorder is caused by a mutation in a specific gene, which can be inherited from one or both parents. Myotonic dystrophy typically presents in adulthood and progresses slowly over time. While there is no cure, treatments can help manage the symptoms.
In addition to muscular dystrophy and myotonic dystrophy, there are several other inherited muscle disorders. These include congenital myopathies, metabolic myopathies, and inflammatory myopathies. These disorders can present at any age and vary in severity, but they all share a common feature of muscle weakness. While the specific causes and treatments may differ, early diagnosis and management are important to improve outcomes and quality of life for those affected.

Muscle disorders can cause weakness, pain or paralysis
Muscle disorders can be inherited, or they can be traced as symptoms of disorders of the nervous system or other systems. Because muscles and neurons supplying muscle cells operate as a functional unit, disease of both systems can result in muscular atrophy and paralysis.
Muscle diseases include a number of rare, often progressive conditions leading to physical disability and frequently reduced life expectancy.

Muscle disorders can lead to physical disability and reduced life expectancy
Muscle disorders are diseases and disorders that affect the human muscle system. They can be inherited or caused by direct abnormalities of the muscles. These are called primary muscle diseases. Those that are traced as symptoms or manifestations of disorders of the nervous system or other systems are not classified as primary muscle diseases.
Muscles and the nerves (neurons) that supply them operate as a functional unit. Therefore, a disease of both systems can result in muscular atrophy (wasting) and paralysis. Muscular atrophy and weakness are among the most common indications of muscle disease. The degree of weakness is usually proportional to the amount of wasting if there is specific involvement of nerve or muscle.
Muscle diseases include a number of rare, often progressive conditions that can lead to physical disability and frequently reduced life expectancy. Conditions that present in childhood are treated with physiotherapy, and improved care has increased the life expectancy of those with muscle disorders.

Primary muscle diseases are direct abnormalities of the muscles
Muscle disorders are diseases and disorders that affect the human muscle system. They can be inherited or acquired, and they can lead to physical disability and reduced life expectancy. Primary muscle diseases are direct abnormalities of the muscles. They are distinct from disorders of the nervous system or other systems, which can also cause muscle atrophy and paralysis.
Primary muscle diseases are characterised by patterns of weakness, loss of muscle tissue, and abnormal electromyogram (EMG) findings or biopsy results. Muscular atrophy and weakness are among the most common indications of primary muscle disease. The degree of weakness is not necessarily proportional to the amount of muscle wasting, but it usually is if there is specific involvement of the nerve or muscle.
Muscle disorders can present at any age, but they often have a genetic component. For example, some conditions present in childhood, while others may not manifest until adulthood. Increased life expectancy and improved care mean that a greater number of patients are seeking treatment as young adults.
Physiotherapy is an important aspect of managing muscle disorders. Early intervention and specialised care can help improve outcomes and quality of life for individuals with these conditions. However, knowledge of muscle disorders outside the specialist area of paediatric physiotherapy tends to be limited.
In summary, primary muscle diseases are direct abnormalities of the muscles that can lead to physical disability and reduced life expectancy. They are characterised by muscle weakness, atrophy, and abnormal test results. Early diagnosis and specialised care are crucial for managing these conditions effectively.

Muscular atrophy is a common indication of muscle disease
Muscle disease is any of the diseases and disorders that affect the human muscle system. Muscular atrophy is a common indication of muscle disease. It is when muscles waste away, usually as a result of a lack of physical activity. Muscular atrophy is not a disease in itself, but a symptom of a disease. It can be caused by damage to the nervous system, such as a spinal cord injury or stroke, or by diseases of the muscles, such as muscular dystrophy or myopathies.
Muscle disorders can cause weakness, pain or even paralysis. They can be inherited, such as muscular dystrophy, or they can be caused by other factors. For example, they can be the result of direct abnormalities of the muscles, in which case they are called primary muscle diseases. However, if they are caused by disorders of the nervous system or other systems, they are not classified as primary muscle diseases.
Muscular atrophy can be a result of a disease or injury that makes it difficult or impossible to move a limb. Over time, without regular movement, the limb can start to appear smaller. This can be reversed with a proper diet, exercise or physical therapy.
Muscular atrophy can also be caused by injuries or diseases of peripheral nerves supplying specific muscles. This can be due to nerve injury from trauma or surgical complications, nerve entrapment, or inherited diseases such as Charcot-Marie-Tooth disease.
