Abstract
We have detected and reported the following findings for the SLTA rating scales 3 and 4 as follows : (1) As points 3 and 4 express the recovery process of aphasia, it is possible to predict the possibility of recovery. (2) It is possible to discriminate between fluctuations and aggravation of aphasic symptoms. (3) The scale ratings manifest a severe aphasic communication level.
In this report we compare the scores of SLTA with those of CADL, to confirm that the scores of rating scales 3 and4 indicate an aphasic's ability in daily communication.
The results indicate that recognition of speech and letters (input) , scores from CADL are superior to those for SLTA. This means that even when high scores are obtained from SLTA, aphasic patients can have difficulty in understanding everyday communication. At the same time, however, with speaking and writing (output) SLTA scores are higher than those of CADL. But when the scores for scales 3 and 4 are added, SLTA is correlative to CADL.
These results confirm that scales 3 and 4 reflect an aphasic's expressive ability in communication.
