  • Title: Treating dysarthria following traumatic brain injury: investigating the benefits of commencing treatment during post-traumatic amnesia in two participants.
    Author: McGhee H, Cornwell P, Addis P, Jarman C.
    Journal: Brain Inj; 2006 Nov; 20(12):1307-19. PubMed ID: 17132553.
    Abstract:
    PRIMARY OBJECTIVE: The aims of this preliminary study were to explore the suitability for and benefits of commencing dysarthria treatment for people with traumatic brain injury (TBI) while in post-traumatic amnesia (PTA). It was hypothesized that behaviours in PTA don't preclude participation and dysarthria characteristics would improve post-treatment. RESEARCH DESIGN: A series of comprehensive case analyses. METHODS AND PROCEDURES: Two participants with severe TBI received dysarthria treatment focused on motor speech deficits until emergence from PTA. A checklist of neurobehavioural sequelae of TBI was rated during therapy and perceptual and motor speech assessments were administered before and after therapy. MAIN OUTCOMES AND RESULTS: Results revealed that certain behaviours affected the quality of therapy but didn't preclude the provision of therapy. Treatment resulted in physiological improvements in some speech sub-systems for both participants, with varying functional speech outcomes. CONCLUSIONS: These findings suggest that dysarthria treatment can begin and provide short-term benefits to speech production during the late stages of PTA post-TBI.
