Muscle cramps, stiffness, and spasm can also be associated with myopathy. Because myopathy is such a general term, there are several classes of myopathy.
Centronuclear (or myotubular) myopathy is a rare muscle wasting disorder that occurs in three forms. The most severe form is present at birth, inherited as an X-linked genetic trait, and presents with severe respiratory muscle weakness. A less severe form of myotubular myopathy that may be present at birth or in early childhood progresses slowly and is inherited as an autosomal recessive genetic trait. The least severe of the three forms of myotubular myopathy presents between the first and third decades of life and is slowly progressive; it is inherited as an autosomal dominant genetic trait.
Myopathy groups
- Congenital myopathies
- Muscular dystrophies
- Mitochondrial myopathies
- Glycogen storage diseases may affect muscle
- Rhabdomyolysis and myoglobinurias
- Myositis ossificans
- Familial periodic paralysis
- Polymyositis, dermatomyositis, inclusion body myositis, and related myopathies
- Neuromyotonia
- Common muscle cramps and stiffness, and tetany
Treatments
Because different types of myopathies are caused by many different pathways, there is no single treatment for myopathy. Treatments range from treatment of the symptomes to very specific cause-targeting treatments. Drug therapy, physical therapy, bracing for support, surgery, and even acupuncture are current treatments for a variety of myopathies.
