lacking normal muscle tone or strength

atrophy

weakness or wearing away of body tissues and structures

bradykinesia

extreme slowness in movment

carpal tunnel syndrome

occur when the tendons that pass through the carpal tunnel (a narrow, bony passage under the carpal ligament that are located just below the inner surface of the wrist) are chronically overused and become inflamed and swollen

chronic fatigue syndrome

a disorder of unknown cause that affects many body systems; also known as myalgic encephalomyelitis

circumduction

the circular movement at the far end of a limb

contracture

the permanent tightening of fascia, muscles, tendons, ligaments, or skin that occurs when normally elastic connective tissues are replaced with nonelastic fibrous tissues

dorsiflexion

the movement that bends the foot upward at the ankle

dyskinesia

the distortion or impairment of voluntary movement resulting in fragmented or jerky motions

dystonia

a condition of abnormal muscle tone that causes the impairment of voluntary muscle movement

electromyography (EMG)

a diagnostic test that measures the electrical activity within muscle fibers in response to nerve stimulation

epicondylitis

inflammation of the tissues surrounding the elbow

ergonomics

the study of the human factors that affect the design and operation of tools and the work environment

exercise physiologist

a specialist who works under the supervision of a physician to develop, implement, and coordinate exercise programs and administer medical tests to promote physical fitness

fasciitis

inflammation of a fascia

fibromyalgia

a debilitating chronic condition characterized by fatigue; diffuse or specific muscle, joint or bone pain; and a wide range of other symptoms

ganglion cyst

a harmless, fluid-filled swelling that occurs most commonly on the outer surface of the wrist

heel spur

a calcium deposit in the plantar fascia near its attachment to the calcaneus (heel) bone that can be one of the causes of plantar fasciitis

hemiparesis

slight paralysis or weakness affecting one side of the body

hemiplegia

total paralysis affecting only one side of the body

hernia

the protrusion of a structure through the tissues normally containing it

hyperkinesia

also known as hyperactivity, is abnormally increased muscle function or activity

hypotonia

a condition in which there is diminished tone of the skeletal muscles

impingement syndrome

occurs when inflamed and swollen tendons are caught in the narrow space between the bones within the shoulder joint

insertion

where the muscle ends by attaching to a bone or tendon; more movable attachment and is the farthest point from the midline of the body

intermittent claudication

pain in the leg muscles that occurs during exercise and is relieved by rest

muscular dystrophy

a group of more than 30 genetic diseases that are characterized by progressive weakness and degeneration of the skeletal muscles that control movement, without affecting the nervous system

myasthenia gravis

a chronic autoimmune disease that affects the neuromuscular junction (where the neuron activates the muscle to contract) and produces serious weakness of voluntary muscles

myocele

the herniation (protrusion) of muscle substance through a tear in the fascia surrounding it

myoclonus

the quick, involuntary jerking of a muscle or group of muscles

myofascial release

a specialized soft-tissue manipulation technique used to ease the pain of conditions such as fibromyalgia, myofascial pain syndrome, movement restrictions, temporomandibular joint (TMJ) disorders, and carpal tunnel syndrome

the degeneration of muscle tissue

myoparesis

a weakness or slight muscular paralysis

myorrhaphy

the surgical suturing of a muscle

neuromuscular

pertaining to the relationship between a nerve and muscle

oblique

slanted or at an angle

origin

where the muscle begins, and it is located nearest the midline of the body or on a less movable part of the skeleton; the less movable attaachment

paralysis

the loss of sensation and voluntary muscle movements in a muscle though disease or injury to its nerve supply

paraplegia

the paralysis of both legs and the lower part of the body

physiatrist

paralysis of all four extremities

sarcopenia

the loss of muscle mass, strength, and function that come with aging

also known as hiccups, is myoclonus of the diaphragm that causes the characteristic hiccup sound with each spasm

sphincter

a ring-like muscle that tightly constricts the opening of a passage way
