Concept Key Terms


Contraindicated  Not recommended because of the potential for harm.
Core Stability  Strength of muscles which demonstrate optimal firing patterns and tension-generating capabilities to "brace" the trunk in anticipation of, and during movement of the head, arms, or legs.
Core Strength  Strength of muscles which demonstrate optimal firing patterns and tension-generating capabilities to create movement of the trunk.
Herniated Disc  The soft nucleus of the spinal disk protrudes through a small tear in the surrounding tissue; also called prolapse.
Intervertebral Discs  Spinal discs; cushions of cartilage between the bodies of the vertebrae. Each disk consists of a fibrous outer ring (annulus fibrosus) and a pulpy center (nucleus pulposus).
Lordotic Curve  The normal inward curvature of the cervical and lumbar spine that is necessary for good posture and body mechanics.
Kyphotic Curve  The normal outward curvature of the thoracic spine that is necessary for good posture and body mechanics.
Microtrauma  Injury so small it is not detected at the time it occurs.
Myofacial Trigger Points  A tender spot in the muscle and muscle fascia that refers pain to a location distant to the point.
Neutral Spine  Proper position of the spine to maintain a normal lordotic curve. The spine has neither too much nor too little lordotic curve.
Posture  The relationship of body parts, whether standing, lying, sitting, or moving. Good posture is the relationship of body parts that allows you to function most effectively, with the least expenditure of energy and with a minimum amount of strain on muscles, tendons, ligaments, and joints.
Referred Pain  Pain that appears to be located in one area, though it actually originates in another area.
Scoliosis  A lateral curvature with some rotation of the spine; the most serious and deforming of all postural deviations.
