Limb-girdle Muscular Dystrophy (MD) refers to a number of related conditions that cause weakness in the big muscle groups at the base of the arms and legs (around the shoulders and hips).
The first symptoms are often mobility problems affecting the hip girdle. It then progresses to the shoulder girdle ("girdle" means the bones around the shoulder or hip).
Symptoms of limb-girdle MD usually begin in late childhood or early adulthood, although the condition can affect people younger or older than this, depending on the specific type. Males and females are equally affected.
If you have limb-girdle MD, you may experience:
The muscle weakness will create problems such as difficulty lifting objects, running or getting out of a low seat.
How quickly limb-girdle MD progresses depends on the specific type. Many types get worse slowly, whereas others can develop more rapidly.
