Clinical manifestations of osteoarthritis
The main symptoms are joint pain, often rest pain, which is manifested as pain after rest and relieved after a moment of activity, but the pain intensifies after too much activity. Another symptom is joint stiffness, which often occurs when you get up in the morning or after your joints maintain a certain position for a long time during the day. Check the affected joints to see joint swelling and tenderness, friction or "click" sound during activity, and muscle atrophy and joint deformity in severe cases.
Medical information network learned that osteoarthritis is still a stubborn disease in clinic, and it is difficult to treat it. Although it sounds terrible, we can prevent and protect early and plan ahead. Among many methods, exercise intervention is the first choice. Through exercise, the muscle strength of lower limbs can be increased. When the muscles around the knee joint are developed, it is equivalent to that the human body has a pair of "knee pads". The key is not to leave the body for 24 hours. It can strengthen the stability of the knee joint. At the same time, the strong muscles of the legs will become an "energy pump" for blood flow. Through the powerful contraction and stretching of the muscles, more blood can be "pumped" to the joints, Then increase the microcirculation around the joint. The key is that articular cartilage has no blood supply, joint fluid is secreted by synovium, and joint fluid is continuously circulated and updated during joint activity. Articular cartilage has to absorb the nutrition and energy of joint fluid through this compression, otherwise the articular cartilage will degenerate and thin due to lack of nutrition. Over time, like rusty bearings, they lose flexibility. Joint fluid can be secreted in large quantities only when it is active, so people who love sports usually have more flexible joints than people who don't love sports.
At ordinary times, do the following two small actions to exercise the muscles around the knee joint anytime and anywhere:
The first action: sit, lift your thighs and kick your calves
Take a sitting position, lift your thighs slowly at a constant speed, and kick your calves out slowly. At this time, you can feel that the quadriceps femoris is very tense. Hold on for a while, and then slowly retract your calves. Remember to do it slowly, and then change the other leg. Do 3-4 groups every day for 3-5 minutes.
The second action: sitting "mountaineering"
Sit in the front of the chair, open your legs the same width as your shoulders, and put your hands in the front of your knees. Your hands and legs must exert force against each other. From beginning to end, you must be in a state of exerting force, and slowly lift up. Your hands always press down, fall down, and then open. At this time, you can feel some tension and fatigue in the thigh muscles, which is a bit like climbing a building or going up a mountain in our daily life. Stick to it 3-4 times a day for 3-5 minutes each time.
