Introduction
In general, abnormal limb movements after cerebral infarction may be caused by reduced limb activity, incomplete recovery of neurological function, cerebral ischemia and hypoxia, post-stroke epilepsy, or abnormal limb muscle tone. If discomfort occurs, prompt medical attention is recommended. In daily life, ensure the patient's living environment is safe by removing obstacles, and assist the patient in maintaining a regular作息 (作息 translates to作息 should be replaced with "routine" or "sleep-wake cycle") and ensuring adequate rest.
Generally, abnormal limb behavior after cerebral infarction may be caused by reduced limb movement, incomplete recovery of nerve function, cerebral ischemia and hypoxia, post-stroke epilepsy, or abnormal limb muscle tone. If discomfort occurs, timely medical consultation is recommended. A detailed analysis is as follows:
1. Reduced Limb Movement
Due to prolonged bed rest and limb weakness following cerebral infarction, decreased limb activity may lead to muscle atrophy and joint stiffness, resulting in abnormal behavior, such as delayed movements. Passive limb exercises, such as joint flexion and extension, and muscle massage should be performed with family assistance 2-3 times daily for 15-20 minutes each session, gradually increasing the amount of activity.
2. Incomplete Nerve Function Recovery
Motor nerves damaged by cerebral infarction recover slowly, causing limbs to lose normal neural control and resulting in abnormal behavior, such as uncontrolled limb movement. Persistent nerve function rehabilitation training, such as grip exercises and limb balance training, combined with acupuncture and physical therapy should be maintained to promote nerve recovery.
3. Cerebral Ischemia and Hypoxia
If cerebral circulation does not fully improve after cerebral infarction, persistent cerebral ischemia and hypoxia may impair motor center function, leading to abnormal limb behavior, possibly accompanied by dizziness. Patients should take medications such as aspirin enteric-coated tablets, cytidine diphosphate-choline sodium tablets, and ginkgo biloba extract tablets under medical guidance to improve cerebral circulation.
4. Post-Stroke Epilepsy
Cerebral infarction can cause abnormal brain tissue discharge leading to epilepsy. During seizures, symptoms such as limb convulsions and abnormal behavior may occur, often accompanied by brief loss of consciousness. Patients should take medications such as carbamazepine tablets, sodium valproate sustained-release tablets, and phenobarbital tablets under medical guidance to control epileptic seizures.
5. Abnormal Limb Muscle Tone
Following cerebral infarction, increased or decreased limb muscle tone may lead to uncoordinated limb movement, causing abnormal behavior, such as limb rigidity or weakness. Patients should take medications such as baclofen tablets, eperisone hydrochloride tablets, and diazepam tablets under medical guidance to regulate muscle tone, combined with rehabilitation training to improve limb function.
In daily life, ensure the patient's living environment is safe by avoiding obstacles; assist the patient in maintaining a regular routine and ensuring sufficient rest; provide psychological support and encourage active participation in rehabilitation therapy.
