Distal Myopathy and Receiving Social Security Disability Benefits
Your proximal muscles are those that are located closest to the center of your body. These are the muscles that are located in your legs, shoulders, upper arms and pelvis.
Your distal muscles are your muscles that are situated the farthest from the center of your body. These are the muscles of your feet, hands, legs and lower arms.
Distal myopathy is a general term for a group of rare progressive genetic disorders. Distal myopathy is marked by atrophy (wasting) of your voluntary distal muscles.
Distal myopathy can begin at any age from infancy to adulthood. However, most of the forms of distal myopathy occur later in life and progress slowly.
Distal myopathy belongs to an even larger group of disorders that are known as the muscular dystrophies. The muscular dystrophies are evidenced by weakness of various voluntary muscles throughout your body. The muscular dystrophies affect different muscles and have different ages at which they begin. They also vary in inheritance patterns and severity.
The different types of distal myopathy are caused by several different genetic defects. All of these genetic defects are not known at the present time. This means that it is a disorder that you inherit from your parents. The inheritance pattern can be autosomal dominant. This means that you only have to inherit a defective gene from one of your parents in order to have the possibility of having distal myopathy. Or, this disorder can also be autosomal recessive. This means that you have to inherit a faulty gene from both of your parents in order to have the possibility of getting distal myopathy.
The primary signs and symptoms of distal myopathy are weakness and wasting (atrophy) in the muscles of your forearms, hands and lower legs. In time, however, other muscle groups may be affected.
As mentioned earlier, the signs and symptoms of distal myopathy usually progress slowly. Other possible signs and symptoms that you may experience are:
A waddling gait.
Impaired hand function
A weak grasp.
The specific signs and symptoms, severity and progression of distal myopathy vary greatly, even among members of the same family with this disorder. Distal myopathy does not affect your intellect.
You or a loved one may be afflicted with distal myopathy. Distal myopathy and/or complications that have developed from it or other illnesses that you have along with this disorder may have caused you or your loved ones disability and inability to work.
