Randomization
A computer-based random number sequence was generated by a SLP who was not involved in eligibility assessment, data collection, or analysis. The investigators were kept unaware of the allocations through the use of sequentially numbered opaque, sealed envelopes for participant. Participants were randomly assigned in a 1:1 ratio to either the intervention group or the control group. Due to the inherent nature of the interventions, blinding of the staff responsible for their administration was not feasible.
