What the literature says about intensity, continuity and material in cognitive and speech & language rehabilitation. Protocols, sample sizes, results — and the sources to check.
-
How intensive should aphasia therapy be?
Ten hours a week in the trials, a little over two in everyday services. This page measures the gap and looks at where it can be closed. -
Is tele-rehabilitation as effective as in-person therapy?
Equivalence with in-person therapy is established. What really matters is not the choice of screen, but what happens between two sessions. -
Is cognitive stimulation recommended in dementia?
The benefits are documented for cognition, communication and quality of life — provided sessions take place at least twice a week. -
Why does exercise material need renewing?
The subject nobody talks about and every clinician lives with: a stock of exercises that never changes ends up training something else.

These pages answer questions clinicians actually ask, drawing on clearly identified publications. Each one states the protocol, the sample size and the result of the studies it cites, then points to the source with its DOI. The aim is that readers can verify — not take our word for it.
We report what the literature says. We do not prescribe, we do not propose any protocol, and we do not replace clinical judgement. Where a finding is fragile, where a result comes from a neighbouring field rather than the one under discussion, or where a common claim is unproven, the page says so.
These pages report the literature. They do not constitute a therapeutic recommendation.
