Cerebral infarction can cause hemiplegic gait. For hemiplegic gait, the focus is on three aspects of treatment: 1. establishing balance, including standing balance, dynamic balance under or different ground stability; 2. making each joint of the patient produce movement, including hip flexion, ankle flexion and extension, ankle dorsiflexion and toe flexion; 3. strengthening the training under support. Because walking is one foot high and one foot low, there is a single limb off the ground, so the affected limb should be strengthened with weight-bearing ability training, including exercise therapy, electrical stimulation, and application of lower limb robots.
