SPT-B then SPT-R
Participants first received Sound Production Treatment - Blocked (SPT-B) for 20 treatment sessions spanning approximately 7 weeks. After a washout period of 2 weeks, they then received Sound Production Treatment - Random (SPT-R) for 20 treatment sessions. Follow-up measures were conducted at 2, 6, and 10 weeks following the end of all treatment.
Sound Production Treatment - Blocked
Sound Production Treatment is a treatment for acquired apraxia of speech. Combines therapist modeling, simultaneous production, articulatory instruction, feedback and repeated practice. SPT-Blocked entailed practicing all treatment targets blocked by target. SPT-Random entailed practicing all treatment targets in a non predictable, random order.
