Myth-buster
610-patient trial found L-DOPA added to stroke rehab improved motor function by less than one point on a 226-point scale — a statistically null result.
This large, well-blinded trial contradicts the popular idea that L-DOPA can boost recovery after a stroke, but it's among the first to test this pairing, so the overall picture remains contested rather than settled.
In a double-blind randomized trial, 610 acute stroke patients received either 100 mg levodopa (with carbidopa) or placebo three times daily alongside standard rehabilitation for 39 days. After three months, the levodopa group scored on average 0.90 points lower on the Fugl-Meyer Assessment of motor function than the placebo group — a difference that was not statistically significant (95% CI, −3.78 to 1.98; P = .54). In plain terms, the drug showed no meaningful benefit over placebo for improving movement after stroke.
Where this fits in the evidence
This is among the first studies we've indexed on L-DOPA for Improved Motor Function — treat it as an early signal until more research accumulates.
