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

Rehabilitation effectiveness depends less on session duration than on the biological potency of stimulation delivered per unit time. Intensity-centred models align more closely with known mechanisms of neuroplasticity and muscle adaptation, offering a more efficient, scalable, and context-responsive pathway to post-stroke recovery. Future research should formalise intensity indices, determine minimal effective thresholds, and evaluate phenotype-specific dosing strategies to support the evolution toward precision rehabilitation.
