Intensity over duration in neurological rehabilitation: exploring evidence for optimised recovery paradigms

Contemporary stroke rehabilitation protocols traditionally emphasise session frequency and treatment duration over intervention intensity-yet emerging evidence suggests we may be preparing patients for therapeutic marathons when their brains demand neuroplastic sprints. Across neuroscientific, behavioural, and clinical domains, convergent data indicate that repetition density, metabolic load, engagement, and temporal compression-not cumulative minutes-constitute the biologically meaningful drivers of neuroplastic and myoplastic adaptation.

This Perspective re-examines current rehabilitation paradigms through an intensity-centred lens, synthesising mechanistic evidence, clinical trials, and cross-cultural implementation models to determine whether high-intensity paradigms can more efficiently exploit neuroplastic windows and muscle adaptation dynamics.
