Background--It has been speculated that the conflicting results demonstrated across poststroke aphasia therapy studies might be related to differences in intensity of therapy provided across studies. The aim of this study is to investigate the relationship between intensity of aphasia therapy and aphasia recovery. Methods--A MEDLINE literature search was conducted to retrieve clinical trials investigating aphasia therapy after stroke. Changes in mean scores from each study were recorded. Intensity of therapy was recorded in terms of length of therapy, hours of therapy provided per week, and total hours of therapy provided. Pearson correlation was used to assess the relationship between changes in mean scores of outcome measures and intensity of therapy. Results--Studies that demonstrated a significant treatment effect provided 8.8 hours of therapy per week for 11.2 weeks versus the negative studies that only provided Conclusions--Intense therapy over a short amount of time can improve outcomes of speech and language therapy for stroke patients with aphasia.

Intensity of Aphasia Therapy, Impact on Recovery
Sanjit K. Bhogal BA (Hon);
2 hours per week for 22.9 weeks. On average, positive studies provided a total of 98.4 hours of therapy, whereas negative studies provided 43.6 hours of therapy. Total length of therapy time was found to be inversely correlated with hours of therapy provided per week (P=0.003) and total hours of therapy provided (P=0.001). Total length of therapy was significantly inversely correlated with mean change in Porch Index of Communicative Abilities (PICA) scores (P=0.0001). The number of hours of therapy provided in a week was significantly correlated to greater improvement on the PICA (P=0.001) and the Token Test (P=0.027). Total number of hours of therapy was significantly correlated with greater improvement on the PICA (P<0.001) and the Token Test (P<0.001).
