Abstract

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