We have discussed what osteoarthritis is and the harmful exercises that people with osteoarthritis need to avoid. Some of our patients know what knee osteoarthritis is and what joint degeneration is after reading this, so they pay attention to their diet, but they don’t dare to exercise for fear that too much movement will aggravate their joint degeneration. And see below we slowly analyze: First of all, with osteoarthritis is not to be active? Some people believe that osteoarthritis is a long-term, chronic degenerative disease, therefore, after having osteoarthritis should be as little activity as possible, and even walking usually do not dare to walk more, especially patients who already have knee pain, more afraid, also do not want to participate in activities. This view is actually incorrect. Patients with chronic osteoarthritis in the progressive phase should actively exercise unless they are in the acute phase of osteoarthritis or have acute pain and joint swelling due to combined synovitis. Proper exercise not only prevents muscle atrophy, enhances muscle strength, stabilizes joints, and slows the progression of joint degeneration, but more importantly, has a preventive effect on geriatric diseases such as “three highs (hypertension, hyperlipidemia, hyperglycemia)” and cardiovascular and cerebrovascular diseases. So, what exercises are suitable for osteoarthritis? 1.Walking. Knee pain is not obvious or alleviated, you should actively start walking exercise. When walking, pay attention to physical and mental relaxation, legs should be slowly lifted and lightly released, to avoid the knee joint bone surface impact, aggravating the injury. The pace should be slow, within 60 steps per minute, for 20-30 minutes per day. Gradually extend the exercise time, exercise intensity to walk without shortness of breath, muscles feel mild soreness, after rest can be quickly recovered as appropriate. 2, quadriceps contraction exercise. Lie with the thighs flat on the bed, or sitting, thighs straight. Make the thigh muscles tense, feel the knee joint downward pressure, so that the patella has upward movement, last 3 to 5 seconds and then relax once, and so on, about 10 times each time, in order to enhance the thigh muscle strength and improve joint stability. The exercise is simple and feasible, usually rest, watch TV, play cards, etc. can be carried out. 3, riding a unicycle. Now many neighborhood public fitness facilities will have a unicycle, similar to riding a bicycle, but more labor-saving. Unicycle can make the knee joint in the case of non-weight bearing flexion and extension activities, without aggravating the wear and tear of the joint, exercise the knee joint. 4. Swimming. It is said that swimming is a golden sport, because it can make the whole body large joints without weight under the exercise, suitable for arthritis, cervical spondylosis, lumbar disc protrusion, frozen shoulder and a variety of pain prevention, it is recommended to adhere to the swimming exercise, but pay attention to warmth in the autumn and winter.
