Conclusions:
- Service Delivery
- Dosage
- The authors found that studies that demonstrated a significant treatment effect "provided an average of 8.8 hours of therapy per week for 11.2 weeks compared with the 4 negative studies that only provided two 1-hour sessions per week for 22.9 weeks" (p. 991).
- The authors conclude that intense therapy over a short amount of time can improve outcomes of speech and language therapy for individuals with stroke-induced aphasia.
