 In this study, and via computed tomography (CT), we calculated the percentage of X-ray low-density (damaged) areas adjacent to the posterior limb of the internal capsule against the total area of the cerebral hemisphere. We were then able to find relationships between these calculations and upper-extremity, residual functions in 34 hemi-paralytic patients with cerebral infarction (18 females and 16 malesrmean age of 73.0 years). When the residual function of the upper extremity was graded into 6 levels, we found that these levels correlated, significantly, with both the size of the damaged area and the ratio of the damaged area to the total cerebral hemisphere. When patients were divided into 3 groups, according to levels of residual function (i.e., nonfunctional hand, assistive hand, functional hand), values of the assistive hand group differed, significantly, with regard to the size and ratio of the damaged areas on the cerebral CT, from both the nonfunctional hand group and the functional hand group.

 These results suggest that calculations of the size and ratio of the damaged area on the cerebral CT may be helpful in estimating the functional prognosis of upper extremities in patients with cerebral infarction.
