There are many factors leading to leg weakness in the elderly, including physiological factors (e.g. overwork) or pathological factors (e.g. cervical spondylosis, osteoporosis, cerebral hemorrhage, etc.). The solutions are different for different causes, and commonly used measures include braking and resting, massage, calcium supplementation, taking drugs for lowering cranial pressure, or surgical treatment. 1. Over-exertion: The elderly are physically weak, and when they have a large amount of activity, it will exceed the load of their body and the phenomenon of weak legs will occur, which is a normal phenomenon, and there is no need to worry too much about it. Symptoms can be relieved by braking and resting with physical therapy and hot compresses. 2. Cervical spondylosis: If you have cervical spondylosis, it may compress the spinal cord nerves, resulting in leg weakness. Massage can be used in conjunction with acupuncture, moxibustion and other physical therapy methods to help dredge the meridians and make the cervical vertebrae that have been scoliotic quickly return to a normal state. However, massage therapy should not be done privately, but with the help of professionals to avoid secondary injuries. 3. Osteoporosis: the elderly calcium loss is more serious, easy to osteoporosis resulting in leg weakness. It is recommended to follow the doctor’s advice to supplement calcium and with vitamin D for treatment, while maintaining balanced nutrition. 4. Cerebral hemorrhage: Cerebral hemorrhage will lead to brain tissue damage, affecting the nervous system and resulting in leg weakness. It can be relieved by taking drugs to lower the cranial pressure (such as mannitol), and if the condition is serious, surgery can be performed under the advice of a doctor. Elderly leg weakness may also be caused by spinal cord lesions, heart failure, diabetes, etc. The solutions for different causes are different, so it is recommended to consult a doctor in time to clarify the cause of the disease and target treatment. Medications should be used under the guidance of a doctor.
