There are two possible conditions that cause elderly people to have trouble lifting their feet when walking. First, the patient may have a cerebral infarction that causes hemiplegia of one half of the limb, in which case the patient will have impaired movement of one half of the limb. The most important manifestation is that the patient cannot lift his foot when walking, which may lead to the phenomenon of the patient’s foot dragging the ground when walking. At this point, the patient must undergo relevant tests, such as cranial CT, which can clarify the diagnosis. After the diagnosis is clear, treatment must be actively carried out to avoid aggravation of the condition, leading to the patient’s hemiplegia. Secondly, it may be that the patient suffers from trauma or prolonged compression, resulting in damage to the peroneal nerve in the lower leg, triggering the symptoms of peroneal nerve injury, which is the phenomenon of foot drop. In this case, once the peroneal nerve is injured it will lead to a situation where the back of the patient’s foot cannot be lifted and cocked up, so it will also cause the patient to be unable to lift his foot when walking. It is important to go to the hospital for electromyography related tests, which can clarify the diagnosis. After the diagnosis is made, local nerve nutrition therapy can be administered to improve the condition.
