Dose effects in behavioural treatment of post-stroke aphasia: a systematic review and meta-analysis.

CONCLUSIONS: There is currently insufficient evidence to determine the effect of dose on treatment response. A dedicated and coordinated research agenda is required to systematically explore dose-response relationships in post-stroke aphasia interventions. A video abstract is available in the Supplementary Material. Implications for rehabilitation The investigation of the effect of dose on treatment outcomes in post-stroke aphasia is an emerging research area with few studies reporting comparison of different amounts of the same intervention. In the acute phase of recovery following stroke, higher doses of treatment provided over short periods may not be preferable, tolerable, or superior to lower doses of the same treatment. In the chronic phase, providing additional blocks of treatment may confer additional benefit for some people with aphasia but with diminishing returns. People with chronic aphasia can achieve and maintain significant gains in picture naming after a relatively brief period of high-dose treatment. PMID: 33164590 [PubMed - as supplied by publisher]
