a form of muscular dystrophy that sets in in adolescence or adulthood and progresses slowly but will affect all voluntary muscles; characterized by generalized weakness and muscle wasting that affects limb and trunk muscles first; similar to Duchenne's muscular dystrophy but less severe; inheritance is X-linked recessive (carried by females but affecting only males)

the most common form of muscular dystrophy; inheritance is X-linked recessive (carried by females but affecting only males)

a form of muscular dystrophy that sets in between 40 and 60 years of age and is characterized by weakness and wasting of the muscles of the hands and forearms and lower legs; inheritance is autosomal dominant

a genetic muscle disorder causing progressive weakness in facial, shoulder, and upper arm muscles, typically starting in adolescence or adulthood

an autosomal recessive form of muscular dystrophy that appears anywhere from late childhood to middle age; characterized by progressive muscular weakness beginning either in the shoulder or pelvic girdle; usually progresses slowly with cardiopulmonary complications in the later stages

a severe form of muscular dystrophy marked by generalized weakness and muscular wasting that affects the face and feet and hands and neck; difficult speech and difficulty with the hands that spreads to the arms and shoulders and legs and hips; the onset can be any time from birth to middle age and the progression is slow; inheritance is autosomal dominant

a form of muscular dystrophy that usually begins between early adulthood and middle age and first affects muscles of the eyelid and throat; progresses slowly with swallowing problems common as the disease progresses; inheritance is autosomal dominant

any pathology of the muscles that is not attributable to nerve dysfunction

muscle tissue breakdown leading to myoglobin release, which can potentially cause kidney damage and other symptoms

a chronic progressive disease characterized by chronic fatigue and muscular weakness (especially in the face and neck); caused by a deficiency of acetylcholine at the neuromuscular junctions

a disorder (usually of unknown origin) of the heart muscle (myocardium)

thickening of tissue in the motor tracts of the lateral columns and anterior horns of the spinal cord; results in progressive muscle atrophy that starts in the limbs

age-related loss of muscle mass, strength, and function, leading to decreased physical performance and increased health risks

myositis characterized by weakness of limb and neck muscles and much muscle pain and swelling; progression and severity vary among individuals

myositis characterized by weakness of limb and neck muscles and much muscle pain and swelling accompanied by skin rash affecting cheeks and eyelids and neck and chest and limbs; progression and severity vary among individuals

inability to coordinate voluntary muscle movements; unsteady movements and staggering gait

a painful condition in which one's joints become stiff or swollen

a painful inflammation of the big toe and foot caused by defects in uric acid metabolism resulting in deposits of the acid and its salts in the blood and joints

chronic breakdown of cartilage in the joints; the most common form of arthritis occurring usually after middle age

an abnormal lateral curve to the vertebral column

a chronic bone disorder causing abnormal bone remodeling, leading to weakened and deformed bones with associated symptoms such as bone pain and fractures

inflammation of a bursa; frequently in the shoulder

a condition in children in which bones soften and become more susceptible to fractures and irregularities due to deficiency of vitamin D, calcium, or phosphate

painful inflammation of the tendon at the outer border of the elbow resulting from overuse of lower arm muscles (as in twisting of the hand)

a condition caused by repetitive motions or prolonged, repetitive use of certain muscles, tendons, or nerves, leading to pain, inflammation, and functional impairment in affected areas
