There are many ways to do quadriceps exercises, and most of them are designed for young adults. Middle-aged and elderly people have osteoarthropathy due to wear and tear of the knee joint. This disease is mostly manifested by knee pain when walking, sometimes accompanied by swelling of fluid in the knee capsule.
The patient is sitting in a chair with both feet on the floor so that the toes of the affected side are pressed against a fixed object (eg, table leg, wall). Extend your knees firmly so that the toes are fixed at the top of the object. (Note:.)
The heel cannot be lifted. Then relax, once, repeatedly. The length of time should be controlled.
Again, it should be noted that every time you extend your knees, you must let the thigh muscles tense and then relax.
If you have difficulty in operating, you can also sit on a chair and repeatedly press the brakes with the foot of the affected side, and the thigh muscles must be tense and relaxed every time you move.
This method not only exercises muscles without wearing out the joints, but also aids in the absorption of joint effusions.
