Old people often wrestle, which is also a common clinical situation. Generally speaking, it needs attention. First of all, does the patient have osteoarthritis due to age, and the pain in lower limb walking decreases sharply, which leads to muscle atrophy, poor walking strength, disharmony and easy aging. Secondly, it is necessary to consider whether the patient has cervical or lumbar degeneration, cervical and lumbar disc herniation, and spinal canal stenosis, which leads to lower limb pain, decreased strength, and is also easy to cause falls. Moreover, a considerable number of patients have formed nerve damage mainly in limbs because of some pathological changes of brain atrophy, which rapidly shrinks and makes the elderly easy to fall. Finally, of course, we can't rule out some mental factors of some patients, so we can look at psychological problems.
