Summary

The goal of this clinical trial is to investigate the impact of direct vs. indirect caregiver training on treatment outcomes following a period of Dynamic Temporal and Tactile Cueing (DTTC) intervention combined with home practice in childhood apraxia of speech (CAS). Forty children with CAS, between the ages of 2;5 and 7;11 years of age, will be recruited for this study. All children will receive DTTC treatment at the frequency of standard care (2x/week) in a university clinic over and 8-week period. Participants will be randomly assigned to one of two groups: the Direct Training Group; the Indirect Training Group. All caregivers will complete an educational module about CAS, will observe all sessions, and will engage in home practice with their children. Caregivers in the Direct Group will receive coaching in the use of DTTC with their child during a portion of each treatment session to support home practice, whereas those in the Indirect Group will not receive detailed guidance for home practice. Caregivers in both groups will practice at home with their children during the treatment phase (3x/week). Following the treatment phase, home practice will continue at a higher frequency (6x/week) during a 4-week follow-up phase. Treatment outcomes will be compared between groups.

Interventions

BEHAVIORAL

Dynamic Temporal and Tactile Cueing (DTTC)

DTTC is a motor-based intervention where the client watches, listens to and imitates the clinician (Strand, 2020). Treatment follows a temporal hierarchy where children receive multisensory cueing to establish accurate movements. First, the child imitates the clinician's production. If inaccurate, the child simultaneously produces the target with the clinician while cueing is provided. Upon achieving accuracy within simultaneous productions, the target is practiced within direct imitation while the clinician adds/fades cues based on the child's productions. When the child accurately produces the target in direct imitation, the target is practiced with varied prosody. Next, the target is practiced within delayed imitation where a child produces a word following a 2-3 second delay after the clinician's production. Upon accurately producing the target at all levels, the word is practiced within spontaneous productions.
