Chiropractic: Good Vibrations

The health of your joint cartilage is improved with vibratory motion. Vibrations allow the hyaluronic acid to be directed evenly among chondrocytes and the extracellular matrix, thus improving delivery of nutrients to chondrocytes in deeper layers and improving transportation of waste products. The average 70 kg (154 lbs) person has roughly 15 grams of hyaluronan in the body, one-third of which is turned over (degraded and synthesized) every day.
