Using electropalatography (EPG) to diagnose and treat articulation disorders associated with mild cerebral palsy: a case study.

By Fiona Gibbon and Sara Wood


Some children with mild cerebral palsy have articulation disorders that are\ud resistant to conventional speech therapy techniques. This preliminary study\ud investigated the use of electropalatography (EPG) to diagnose and treat a longstanding\ud articulation disorder that had not responded to conventional speech\ud therapy techniques in an 8-year-old boy (D) with a congenital left hemiplegia.\ud The targets for EPG therapy were speech errors affecting velar targets /k, g, n/,\ud which were consistently fronted to alveolar placement [t, d, n]. After 15 sessions\ud of EPG therapy over a 4-month period, D’s ability to produce velars improved\ud significantly. The EPG data revealed two features of diagnostic importance. The\ud first was an unusually asymmetrical pattern of tongue-palate contact and the\ud second was unusually long stop closure durations. These features are interpreted\ud as a subtle form of impaired speech motor control that could be related to a mild\ud residual neurological deficit. The results suggest that EPG is of potential benefit\ud for diagnosing and treating articulation disorders in individuals with mild\ud cerebral palsy
