Clinical application of Loewenstein Occupational Therapy Cognitive Assessment Battery-Second Edition in evaluating of cognitive function of Chinese patients with post-stroke aphasia.
OBJECTIVE
To investigate the clinical application value of Loewenstein Occupational Therapy Cognitive Assessment battery in Chinese patients with post-stroke aphasia.


METHODS
Cognitive functions of 59 Chinese patients with aphasia following a stroke were assessed with the Chinese version of the second edition of LOTCA battery and their linguistic functions were tested with the Western Aphasia Battery (WAB) Scale, respectively. The Results of LOTCA were analyzed and compared across different groups, in the light of gender, age, educational background, the length of illness, and the degree of aphasia.


RESULTS
Neither the score of subtests of the LOTCA nor the overall scores of LOTCA of aphasia patients with different gender and educational background differed (all P>0.05). In different age groups, apart from thinking operation (F=3.373, P=0.016), visuomotor organization (F=3.124, P=0.022), attention (F=3.729, P=0.009) and the total score (F=2.683, P=0.041), there was no difference in terms of the other subtest scores of LOTCA (all P>0.05). In the groups of different length of time with illness, apart from orientation (F=2.982, P=0.039) and attention (F=3.485, P=0.022), the score of other subtests and the total score of LOTCA were not different (all P>0.05). In the groups of different degree of aphasia, apart from attention (F=2.061, P=0.074), both the score of other subtests and the total score of LOTCA differed (all P<0.05).


CONCLUSIONS
LOTCA might be suitable to assessing the cognitive ability of post-stroke Chinese patients with aphasia.
