What are myopathies?
Myopathy is a disorder of the skeletal muscles. Muscle disorders arise from abnormalities that affect the muscle’s structure or metabolism, and have a variety of causes. Some are inherited while others are acquired.
What causes severe muscle weakness in legs?
Muscle weakness is commonly due to lack of exercise, ageing, muscle injury or pregnancy. It can also occur with long-term conditions such as diabetes or heart disease. There are many other possible causes, which include stroke, multiple sclerosis, depression, fibromyalgia and chronic fatigue syndrome (ME).
What is a primary myopathy?
Summary. Primary mitochondrial myopathies (PMM) are a group of disorders that are associated with changes in genetic material (e.g. depletions, deletions, or mutations) found within the DNA of mitochondria (mtDNA) or with genes outside the mitochondria (nuclear DNA), affecting predominantly the skeletal muscle.
What is disuse myopathy?
Cachectic Myopathy is also known as disuse atrophy, it is responsible for marked wasting and weakness of muscles. Laboratory studies are generally non-specific. Muscle biopsy may show type 2 fiber atrophy. Cachectic myopathy remains a diagnosis of exclusion.
What is sarcoid myopathy?
INTRODUCTION. Sarcoidosis, a multisystem disorder of unknown etiology, commonly presents clinically with bilateral hilar adenopathy, pulmonary infiltrates, skin and/or eye lesions, or a combination of these features. Musculoskeletal and neuromuscular manifestations occur less commonly.
What is neuro myopathy?
The myopathies are neuromuscular disorders in which the primary symptom is muscle weakness due to dysfunction of muscle fiber. Other symptoms of myopathy can include include muscle cramps, stiffness, and spasm. Myopathies can be inherited (such as the muscular dystrophies) or acquired (such as common muscle cramps).

Can a pelvic injury cause weakness in legs?
A traumatic injury to the leg or to the pelvic region can damage muscles, nerves or joints, resulting in leg weakness. Most of the time, if you experience a leg or pelvic injury that is severe enough to cause weakness, you should also expect to experience pain.
What causes asymmetric leg weakness?
Some causes of asymmetric leg weakness include spinal cord damage that is worse on one side of the spine, abnormal growths that affect one side of the spine or one half of the brain more than the other, and injury to the leg nerves that is more pronounced in one leg. Can leg weakness be genetic?
