Skin temperature on the forearm,leg,and foot on the side contralateral to the site of infarction were significantly lower than on the ipsilateral side during the whole 6-month follow-up period.Asymmetrical temperature was associated with the presence of pyramidal tract signs in hemispheric infarction and with the presence of Wallenberg's syndrome in brain stem infarction.In hemispheric infarction,the degree of asymmetrical temperature correlated with the severity of limb paresis.A temperature decline in the limbs contralateral to the site of infarction seems to be a frequent,long-lasting consequence of autonomic failure in patients with stroke.The phenomenon seems to be associated with pyramidal tract signs and the presence of Wallenberg's syndrome. |
