Verbal Instruction Model (VIM) in voice therapy.

The stumbling-block in voice therapy is the patient's generalization of the new voice behavior in everyday life. Traditionally voice therapy is based on demonstration, i.e. during the therapy session the speech therapist uses her own voice and body to demonstrate for the patient how to produce voice in different training tasks. During the last decade a new voice therapy strategy, the Verbal Instruction Model (VIM), has been developed by the author. In VIM the speech therapist uses verbal instructions instead of demonstration when conveying the training tasks to the patient. Our clinical experience has shown that VIM seems to help getting over the stumbling-block of generalization. However, evidence for VIM voice therapy outcome remains to be scientifically studied and confirmed. The purpose of this paper is to describe VIM voice therapy and to discuss therapy strategies in the light of motor learning principles. [ABSTRACT FROM PUBLISHER]
