Contents of different physical therapies. The physical therapy for OA mainly includes aerobic exercise and neuromuscular exercise. The purpose of aerobic exercise is to improve body fitness, muscle strength and improve body metabolism. There are many different models of aerobic exercise, such as swimming, jogging, Tai Chi and yoga. The neuromuscular exercise aims to improve joint function and stability, as well as relieve symptom pain of OA patients. In addition, there are also other helpful physical therapies that rely on external instruments, such as acupuncture and Low intensity pulsed ultrasound treatment, which can relieve symptom pain and improve joint function. Notably, most of the time, a combination of physical therapies is required for better therapeutic effectiveness.
