Tendon

A flexible but inelastic cord of strong, fibrous collagen tissue, attaching a muscle to a bone.

Joint

a structure in the human or animal body at which two parts of the skeleton are fitted together

Atrophy

The wasting away of decreasing in size, and weakening of muscles from lack of use.

Contracture

The permanent and often painful shortening of a muscle or tendon, usually due to lack of activity.

Arthritis

Arthritis is a group of conditions that cause inflammation and pain in the joints. It is a common condition that affects people of all ages, but it is more prevalent in older adults. 

Rheumatoid Arthritis

A chronic progressive auto-immune disease-causing inflammation in the joints and resulting in painful deformity and immobility, especially in the fingers, wrists, feet, and ankles.

Osteoporosis

A disease that causes bones to become porous and brittle, causing them to break easily

Hip Fracture

broken bone in the hip, a key health problem among the elderly, usually due to a fall or other kind of trauma involving direct impact to the hip bone which has been weakened by osteoporosis.

Hip Replacement

is a type of surgery that involves the removal of the damaged hip joint and surrounding cartilage and replacement with a prosthesis.

Knee Replacement

a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability.

Weight Bearing

Partial Weight Bearing (PWB)

a doctor’s order stating that a person is able to support some body weight on one or both legs.

Non-Weight Bearing (NWB)

a doctor’s order stating that a person is unable to touch the floor or support any body weight on one or both legs.

Full Weight Bearing (FWB)

Abduction Pillow/Wedge

A wedge-shaped pillow positioned between the legs to immobilize and position the hips and lower extremities, usually used after a hip surgery.

Central Nervous System (CNS)

The part of the nervous system which consists of the brain and spinal cord, to which sensory impulses are transmitted and from which motor impulses pass out, and which coordinates the activity of the entire nervous system.

Brain

An organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation and intellectual and nervous activity.

Spinal Cord

The cylindrical bundle of nerve fibers and associated tissue that is enclosed in the spine and connects nearly all parts of the body to the brain, with which it forms the central nervous system.

Nerves

(In the body) a whitish fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs.

Hemiplegia

Paralysis on one side of the body.

Parkinson’s Disease

a progressive disease of the nervous system marked by tremors, muscular rigidity, and slow, imprecise movement, chiefly affecting middle-aged and elderly people.

Multiple Sclerosis (MS)

A chronic, typically progressive disease involving damage to the sheaths of nerve cells in the brain and spinal cord; symptoms include numbness, impairment of speech and of muscular coordination, blurred vision, and severe fatigue.

Spinal Cord Injury

Damage to the spinal cord that causes changes in its function, either temporary or permanent.

Paraplegia

Loss of function of lower body and legs.

Quadriplegia

The loss of function of the legs, trunk, and arms.

Traumatic Brain Injury (TBI)

Is an insult to the brain from an external mechanical force, possibly leading to permanent or temporary impairment impairment of cognitive, physical, and psychosocial functions.

Cardiac

relating to the heart

Artery

Any of the muscular-walled tubes forming part of the circulation system by which blood, mainly that which has been oxygenated, is conveyed from the heart to all parts of the body

Capillary

Any of the fine branching blood vessels that form a network between the arterioles and venules.

Vein

Any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.

Coronary Artery Disease (CAD)

: impedance or blockage of one or more arteries that supply blood to the heart, usually due to atherosclerosis (hardening of the arteries).

Angina

a chest pain, pressure, or discomfort usually associated with heart muscle that is not getting enough oxygen.

Congestive Heart Failure (CHF)

heart failure in which the heart is unable to maintain adequate circulation of blood in the tissues of the body or to pump out the venous blood returned to it by the venous circulation.

Peripheral Vascular Disease (PVD)

poor blood circulation in the legs, feet, arms, or hands caused by atherosclerosis.
