This quasi-randomized pilot clinical trial investigated the impact of treatment frequency on outcomes in 45 adults with chronic poststroke aphasia. Participants underwent six 1-hour sessions of script training across three frequency conditions. Results indicated that session frequency did not significantly affect treatment outcomes, with all conditions showing positive effects on accuracy, speech rate, and generalization at follow-up.
Key findings
- All treatment conditions showed positive effects on accuracy and speech rate from baseline to posttreatment.
- No significant differences in accuracy or rate were observed between the three treatment frequency conditions.
- Generalization of essential information units improved from baseline to 4 weeks posttreatment, though not reliably from baseline to posttreatment.
Why it matters
Understanding the optimal frequency for aphasia treatment can help clinicians design effective rehabilitation programs. This study suggests that varying session frequency may not be critical, allowing for flexibility in treatment planning.
