Why are stiff joints?
For easy and easy movement, the joints are firmly protected by a layer of cartilage and are always supplied with enough mucus to help lubricate the joints and to prevent shocks. Thanks to this mechanism, the change of postures or the process of movement of people can be rhythmic, flexible. However, when the "joint is dry", there will be stiffness, the joints will be painful when the movement or the sound of "crunch", "hemp". Sometimes, they may be alone, but may also include swelling, heat, pain, redness, and even restriction of movement. Several studies have shown, accompanied by signs of joint stiffness, cartilage damage, progressive wear. Up to 90% of people over the age of 35 have begun to experience these changes because of "degraded joint cartilage." At that time, the cartilage surface becomes rough, begins to wear away, breaks, causing the two ends of the bone to lose its cushioning effect to reduce the force and friction should rub together, causing prolonged pain and many consequences. Other such as thoracic bone, joint deformity, severe stiffness. The result is the use of "overload", excessive sports, sitting too long ..., causing cartilage to degenerate.
