For physical therapists who treat patients suffering from back pain and weakened core muscles, the Power Plate is a beneficial piece of technology. The machine vibrates to stimulate reflexive muscle contractions 25-50 times per second. The Power Plate increases blood circulation to core spinal and abdominal muscles that have weakened over time due to sedentary lifestyle habits. For people who are lacking in their level of fitness, the Power Plate is designed to ease the difficult transition from an inactive to an healthy lifestyle. While it remains unclear whether this vibration technology can replace other forms of exercise, some physicians believe it can greatly complement any exercise or physical therapy regimen. "The Power Plate is contracting 30-50 times per second, so those muscles are fatiguing much more rapidly than they would in any other traditional exercise. And for patients that don't exercise, it's a great step to get them into the gym because it doesn't hurt and it's very safe." The advantage to Power Plate technology is the strengthening of muscles without strain on joints and ligaments for recovering patients. The increased oxygen and blood flow to weakened structures in the body help promote healing and reducing recovery time. The end result for patients are increased muscle strength, flexibility, range of motion, and bone density.
