On the correlation between training modalities and recovery stages in poststroke robotic rehabilitation of the upper limb: a systematic review.

PMID 42063147WHAT IT FOUND
Robotic therapy choices should match the stroke recovery stage.
Assistive modes with electrical stimulation worked best for chronic patients. Active-assistive modes with bio-signal triggers yielded greater gains for subacute patients. Evidence for the acute phase remains too limited to guide practice.
Key findings
01In the chronic phase, assistive modalities combined with electrical stimulation and gravity compensation produced the most significant clinical results.
02During the subacute phase, active-assistive approaches using electrical stimulation or bio-signal triggers led to major improvements, benefiting from higher neuroplasticity.
03The acute phase has too few studies to draw relevant conclusions, though assistive modalities were the most widely employed in the limited available trials.

What it does not show
Many studies reported overall outcomes without isolating the effect of specific training modalities, making it difficult to attribute success to one component. The acute phase was underrepresented, with too few studies to draw clinically relevant conclusions. The review did not account for therapy duration, frequency, or patient impairment severity, which likely influence outcomes. The analysis relies on published trials rather than real-world clinical practice data.
Declared interests
The study was funded by the Italian Ministry of Education, University and Research (Ministero dell’Istruzione, dell’Università e della Ricerca). No other conflicts of interest were declared.
The easy way to misread this
Do not assume that a specific robotic mode causes improvement in isolation. Many effective interventions combined robotic assistance with other therapies like electrical stimulation or botulinum toxin, and the review could not separate the contribution of the robot from these concurrent treatments.
