Your stiff neck, sore back or aching muscles may be due to fascia, layers of tissue and fluid that surround and stabilize your bones, muscles, nerves and blood vessels. Certain factors, such as repetitive movement, trauma or limited physical activity (such as sleeping), can cause the fascia to thicken and tighten up around the muscles. When that happens, you’re left with pain and limited mobility.
Percussive massage helps distribute the thickened fascia fluid to relieve the pressure and tightness you feel. Repeated pressure at high speed thins the fluids, making the fascia more pliable so that your muscle can move more easily and efficiently.
