Arthritis is a common disease maanged by physiotherapists. Anyone can develop arthritis, but it becomes more common as we age. Women are more likely to develop arthritis than men, especially after age 50. People with arthritis typically experience pain when using their joints, or even swelling in and around the joints. Physiotherapists play an important role in treating arthritis by managing joint pain, swelling and stiffness, thereby reducing discomfort in patients' daily lives. At the same time, a tailor-made exercise training plan will be designed to improve joint stability and range of motion, allowing patients to move freely and engage in their interests in life. For those over 50 years old, methods to prevent arthritis include regular exercise, quitting smoking and drinking, controlling weight, and developing good posture habits to reduce the burden on joints.
