Muscular dystrophy is most commonly found in boy and in their early childhood years, other types of muscular dystrophy don’t surface until adulthood.

Duchenne muscular dystrophy symptoms include; Frequent falls, difficulty getting up from a lying or sitting position, trouble running and jumping, waddling gait, large calf muscles and learning disabilities Symptoms - The two most common muscle dystrophies are Duchenne and Becker Muscular Dystrophy. Other more rarer muscular dystrophies include Myotonic, Limb-girdle, Congenital, Fascioscapulohumeral (FSHD) and Oculopharyngeal. (RIGHT BEFORE BECKER MUSCULAR DYSTROPHY)
