A comparison of oral motor and production training for children with speech sound disorders

Despite the many debates about the usefulness of nonspeech oral motor exercises (NSOMEs) in the treatment of speech disorders, few controlled experiments have evaluated their efficacy in the remediation of phonological/articulatory disorders (PADs). More importantly, the relative effect of NSOMEs compared with traditional production treatment (PT) has not been established. The current study employed an alternating treatment design to evaluate changes in production of sounds targeted by NSOMEs and PT in nine children with PAD. Each subject received treatment on two linguistically distinct sounds in which one sound was treated with NSOMEs and the second sound was targeted with PT. The difference in treatment efficacy, measured as the percentage change in target production for NSOMEs versus PT, was compared using a paired T test. Because NSOMEs typically are used to ready a child for subsequent PT, comparison of PT treatment accuracy was made between NSOME-first and PT-first sessions. Results demonstrated a statistically significant effect of treatment type with greater production gains with PT compared with NSOMEs. Further, no facilitative effect of NSOMEs on PT was noted; however, the choice of distinct treatment targets may have contributed to this null effect. Although additional investigation is warranted, the current investigation does not support the efficacy of NSOMEs in the treatment of PAD.
