Strokes are divided into ischemic strokes (also called cerebral infarction) and hemorrhagic strokes (also called cerebral hemorrhage). Stroke is followed by hemiplegia of the limb. A portion of patients with hemiplegic limbs will recover better after 3 months with good standardized rehabilitation treatment and can walk independently with the help of crutches. However, after a period of time, Guo Lei’s limb muscles may become spastic, resulting in difficulty in walking on the lower limbs, or in the mobility of the upper limbs. A 75-year-old female patient had left-sided limb hemiparesis after cerebral infarction, but after 6 months, she was able to walk independently without the help of crutches. She felt good recovery. Although she was depressed because of the post-stroke period, her mood was also significantly restored with antidepressant medication and other treatments. However, 1 year after the onset of the stroke, she could not walk instead. When she walked, she felt spasm and pain in the original limb that used to be hemiplegic. Muscle cramps. This was due to muscle spasms after a stroke had occurred. We treated the spastic muscles with botulinum toxin type A injections, and the spasticity has not returned for 6 months now. He is able to walk independently and his muscles are not painful anymore. So, certain medications and other measures can make the recovery of stroke patients smoother.
