Abstract

Spontaneous speech samples of 28 patients were analyzed using a computer-assisted method before and after seven weeks of intensive language treatment. We focussed on the following four basic parameters: percentage words, percentage open class words, syntactic completeness and MLU. A 3-factorial-ANOVA revealed a significant main effect for type of aphasia (fluent vs. non-fluent) for all four parameters. In comparison with a conventional rating scale, the basic parameters proved to be much more sensitive to change. Thus, the computer-assisted analysis of basic parameters represents a clinically applicable instrument to measure even small changes during the course of recovery from aphasia.
