In cerebral infarction patients with hand and foot cramps, it is considered that the muscle contracture is caused by the increased muscle tone of the affected limb, especially when it is cold, the hand and foot cramps on the affected side can occur. For the above situation, the patient can be given warmth, and if necessary, Chinese medicine or medium-frequency pulsed electric therapy can be applied to reduce the muscle tone of the paralyzed limb, and if necessary, the patient can also be given oral haloperidol and other drugs to reduce muscle tone. Hand and foot cramps in cerebral infarction patients may be caused by osteoporosis due to total vitamin D deficiency due to low sun exposure, and hand and foot cramps may occur at night. In these cases, the patient can be given a serum total vitamin D measurement and treated with vitamin D as well as calcium carbonate and other drugs.
