Abstract
Muscular Dystrophy (MD) is a group of genetic diseases in which the voluntary muscles are affected. MD causes weakness and degeneration of muscles progressively overtime. It is most common in young males; but in rare cases it can occur in females. MD is caused by mutations on the X-chromosome gene that prevents the body from producing an essential muscle protein called dystrophy, in which without it muscles weaken (Leung & Wagner, 2013). There are 9 major types of MD, which include Becker, Emery-Dreifuss, Myotonic, Facioscapulohumeral, Congenital, Oculopharyngeal, Distal, Limb-girdle, and the most common Duchenne Muscular Dystrophy (DMD) (CDC, 2016). DMD is caused by the mutation of x-linked recessive inheritance, in which this is caused by when the mother carries the affected X-chromosome gene and passes it to her child. 1 in 3,600 children are presented with such disability, and usually appears in boys ages 3-5 years old (Ciafaloni & Moxley, 2008). There are many symptoms that can be presented, and usually begins by weakening the involuntary muscles and moves to voluntary muscles. DMD can cause many several heart, respiratory, and learning problems; however, there is several treatments that can slow down the progression and allow the patient to remain mobile as much as possible (Selner & Rleonard, 2016). Such treatments include medication, braces, and physical therapy. Physical Therapy (PT) allows slow progression of severe cases caused from DMD, such as…
