A pilot study of use-dependent learning in the context of Constraint Induced Language Therapy

TLDR

The study applies use‑dependent learning principles from motor rehabilitation, specifically Constraint Induced Therapy, to language rehabilitation in individuals with chronic aphasia. Participants received intensive, massed‑practice sessions either with forced‑use Constraint Induced Language Therapy or with unrestricted communication modes, using identical stimuli and tasks. Both interventions produced positive outcomes, but CILT led to more consistent improvements on standard aphasia measures and clinician‑rated narrative discourse, indicating its viability for aphasia rehabilitation.

Abstract

This investigation reports the results of a pilot study concerning the application of principles of use-dependent learning developed in the motor rehabilitation literature as Constraint Induced Therapy to language rehabilitation in a group of individuals with chronic aphasia. We compared treatment that required forced use of the language modality, Constraint Induced Language Therapy, (CILT) to treatment allowing all modes of communication. Both treatments were administrated intensively in a massed practice paradigm, using the same therapeutic stimuli and tasks. Results suggest that whereas both interventions yielded positive outcomes, CILT participants showed more consistent improvement on standard aphasia measures and clinician judgments of narrative discourse. These findings suggest that CILT intervention may be a viable approach to aphasia rehabilitation. (JINS, 2006, 12, 843–852.)
