Do predictors of motor recovery differ between robotic and conventional post-stroke rehabilitation?

PMID 42121151WHAT IT FOUND
Baseline motor severity predicted recovery in both groups.
Age mattered only for conventional therapy, while neglect and wrist strength mattered only for robotic therapy. These differences suggest treatment choice may depend on specific patient profiles rather than one-size-fits-all.
Key findings
01Baseline Fugl-Meyer Assessment score was the most influential predictor of motor recovery across all models.
02Age was a significant predictor for conventional therapy outcomes but not for robotic therapy.
03Neglect and wrist muscle strength were key predictors for robotic therapy but not for conventional therapy.

What it does not show
The sample size was relatively small (190 participants), which limits the statistical power and generalizability of the predictive models. The analysis was secondary to an RCT designed to test efficacy, not to identify predictors, so important variables like detailed cognitive assessments were not collected. The robotic intervention used four different devices, introducing heterogeneity in the treatment received. The study only looked at short- to medium-term outcomes, so it is unknown if these predictors hold for long-term recovery. The paper does not report if the outcome assessors were blinded to treatment allocation.
Declared interests
The study was funded by the Italian Ministry of Health, the Ministry of University and Research, and the EU Horizon Europe Research and Innovation Programme. No specific conflicts of interest with device manufacturers were declared in the provided text.
The easy way to misread this
Do not interpret these predictive differences as proof that robotic therapy is superior for older patients or inferior for those with neglect. These are associations from a secondary analysis of a small sample, not causal effects established by a trial designed for this purpose.
