Apraxia of speech (AOS) is a motor speech disorder associated with an impairment in
motor planning and programming. It is therefore a logical step to derive treatment of the
disorder from the principles of motor learning. Principles of motor learning refer to relatively
predictable benefits of certain practice conditions over others (e.g., random practice enhances
learning compared to blocked practice). A number of studies have begun to examine
principles of motor learning in treatment for AOS (e.g., Austermann Hula et al., 2008; Katz
et al., 2010). The current project aims to continue the investigation of motor learning
principles and its application to motor speech disorders. In particular, the primary goal of this
study is to examine the role of feedback control in treatment for AOS. Two types of feedback
control are typically distinguished: self-controlled feedback and clinician-controlled feedback
(Chiviacowsky & Wulf, 2004; Chiviacowsky & Wulf, 2007; Janelle, Barba, Frehlich,
Tennant, & Cauraugh, 1997; Wulf, 2007). A secondary goal is then to examine the efficacy
of script training for AOS. Youmans et al. (2011) provided promising initial evidence
supporting its efficacy for AOS, yet no studies have replicated these findings (Ballard et al.,
2015).
The results of this study suggest that self-controlled feedback is more efficacious in
treating adults with AOS than clinician-controlled feedback. Greater improvements of
performance for self-controlled feedback were noted especially in accuracy of productions.
There was the potential to impact rate of speech as well. Findings across conditions (treated
versus untreated scripts) also indicate that script training is an efficacious method of treating
adults with AOS. / Public Health
