Calpainopathy is the most common type of autosomal recessive limb-girdle muscular dystrophy (LGMD).[2] It preferentially affects the muscles of the hip girdle and shoulder girdle.

No disease modifying pharmaceuticals have been developed as of 2019, although physical therapy, lifestyle modification, and orthopedic surgery can address symptoms.
