Muscle atrophy in the elderly will cause a decrease in muscle strength and affect limb movement. When muscle atrophy occurs, the elderly need to take the initiative to move the atrophied limb frequently to prevent venous thrombosis. Do not compress the atrophied limb while sleeping, and family members should also help the elderly to passively move the atrophied limb and joints to prevent further atrophy of the limb and joint contracture deformity from occurring. You can use warm towels to warm the atrophied area to promote local blood circulation, or you can go to the hospital regularly for acupuncture, massage and other rehabilitation training, and nutritional nerve therapy. The atrophied limb is not sensitive to temperature, so when the weather becomes cold, you need to add clothes in time to prevent poor blood circulation in the affected limb, which affects the activity. The most common cause of muscular atrophy in the elderly is cerebrovascular disease leaving limb paralysis, usually pay attention to regular medical checkups, monitoring blood sugar, blood lipids, blood pressure, and active drug control.
