Spastic paraplegic gait: severe bilateral spastic hypertonia, patient has tonic inversion of both lower extremities with compensatory trunk movements, walking effort, and scissor-like gait. It is seen in spastic paraplegia, cerebral palsy, transverse spinal cord damage, cerebral palsy, hereditary spasticity, paralytic lateral sclerosis, and corticospinal tract degeneration. There are many patients who had a stroke, and their families often feel surprised because the patient usually never sees a doctor or takes medication, and they always thought he or she was healthy, but they never expected to have a stroke all of a sudden. In fact, health is only an illusion of the patient and family members. Patients who have a stroke often have risk factors for stroke without knowing it. If these people can detect the disease early and take effective treatment measures, strokes can be prevented. Therefore, for people aged 40 or older, especially those with hypertension, diabetes or a family history of stroke, regular physical examinations and early detection and early treatment of risk factors for stroke can prevent the occurrence of stroke.
