Competing sentence test (CST) results in patients with cerebrovascular accident (CVA)

As the cerebrovascular diseases (CVD) are among the most common anomalies that are directly or indirectly affecting the auditory cortex, studying in this area is important. We tried to evaluate the function of CANS in a group of 50-70 years old cerebrovascular accident (CVA) patients with no hearing complaint by competing sentences test (CST) as a dichotic speech test. Method and Material: This cross-sectional analytical study was conducted at Loghman-e-Hakim hospital between 22, august 1999 and 20, July 2000 in a group of 30 normal 50-70 years old persons and a group of 40 patients with CVA including 30 patients with abnormal CT scan and 10 patients with normal CT scan. The results point out the mean scores of CST in the normal group were at normal range (80-100%) in both ears. And mean scores of CST decreased in the patients groups. There were significant difference between mean scores of CST in the patients with CVA and control groups. CST seems to be a valuable test in the CANS test batteries for the cerebrovascular diseases.
