Acute:

Symptoms or conditions that have developed recently, which are usually sharp or severe.

Chronic:

Symptoms or conditions that have persisted for weeks, months or even years, which can range from mild to severe.

Degeneration:

A breaking down of bodily tissue, such as that in the spine. Poor spinal mechanics, trauma and aging can cause a thinning or degeneration of spinal disks, the same way driving a car wears out tires.

Health:

To chiropractors, health isn't just an absence of disease, but a state of positive mental, physical and spiritual functioning.

Misalignment:

Improperly aligned joints in the body. These are usually associated with subluxations, and can stress your neuromusculoskeletal system.

Spasm:

Involuntary shortening of muscle fiber. Spasm often occurs after an injury, but many things can cause it. During spasm, muscles cannot be relaxed and the associated joints have a decreased range of motion.

Strain:

An injury to muscles or ligaments caused by overstretching, overuse, tearing, tension or torsion. Poor posture can also strain these tissues, as it places increased demands on them.

Subluxation:

An area in the spine that moves improperly. It occurs when spinal bones become misaligned or lose their normal range of motion. A subluxation can stress the entire nervous system.

Vertebral subluxation complex:

A number of conditions associated with a subluxation that includes abnormal joint motion, abnormal nerve expression, abnormal muscle function, abnormal soft tissue and abnormal function of internal organs and systems.

Whiplash:

An injury that occurs when the head is suddenly accelerated and decelerated, in a whip-like motion, forward to backward or side to side. While many people associate whiplash with motor vehicle accidents, the injury can also occur during sports or falls.
