LOGOS – APHASIA:A computerized tool designed to be used by the speech and language pathologist for the assessment of Aphasia in Greek
Definition of the problem:The process of aphasia assessment is a detailed and
complex aspect for the clinician. New technologies canpossibly present the option to evaluate a situation fasterand more accurately.
Research Questions:What are the effects of computerized assessment
procedures designed for the evaluation of Greek aphasicadults?
Does the computer software LOGOS – APHASIA thatwas developed specifically for this use in Greek, do the jobit was designed to do?
In particular is the software working efficiently for:test administrationscoring interpreting communication
Is it easy to use:clinician perspective?patient perspective?
Can it be considered that it is accepted as a clinicaldiagnostical tool?
Software Description:The aim is to create a computerized clinical tool for the
Greek language, that the clinician can use as an objectivemethodology for the evaluation of aphasia.
The LOGOS – APHASIA test evaluates five sections:1. Ακουστική Κατανόηση - Listening (Comprehension)2. Λεξιλόγιο - Vocabulary 3. Ανάγνωση - Reading4. Γραφή - Writing5. Γνωστικές Ικανότητες - Cognitive Ability
According to the patient needs, the clinicial can apply any of the above section evaluation or the evaluation of the whole five sections.
At the end of each running of an evaluation test the software automatically evaluates the answers and produces results to external text files. The formations of the results are of two types:
score in each evaluation sectionDetailed report on the results that the patient can
not function.Test administration differs every time it runs making it
possible to retest the same patient on equivalent material.
Methodology:Participants: Normal population (<40 years old),
N=110 (final year students of the department of Speechand Language Therapy, TEI of Epirus, Ioannina, ELLAS)1. They were tested using the software on theirlinguistic abilities2. Asked to fill in a questionnaire, consisted of threesections, as follows:
Personal details and medical historytheir opinion of the process as end userstheir opinion of the process as to their clinical
identity

Summary of the work
Systemic Approach of Evaluation Procedures
Speech production: Presently no objective methods for automatically scoring therefore the clinician in his own way can evaluate the certain section in a subjective manner.
Purpose of the study was to use only objective evaluation methods.
The results indicate that such a system has the potential to become a valuable clinical tool for the clinician in evaluating aspects of adult language.
Future workSoftware Evaluation:
• on all age groups of normal population• on aphasic patients• on other neurogenic communication problems
Scheduled for LOGOS – APHASIA upgrades:• Speech production instructions & Recording for further process & evaluation (not in real time).• Hand writing Recording• Patients Database Handling
