Early versus late ‐applied constraint‐induced movement therapy: A multisite, randomized controlled trial with a 12‐month follow‐up

This study aimed to compare the long‐term effects of CIMT applied 6 months after stroke with the results of CIMT applied within 28 days post‐stroke. MethodsThis study was a single‐blinded, multicentre, randomized controlled trial with a crossover design. Forty‐seven patients received CIMT either early (within 28 days) or 6 months after stroke. Both groups received standard rehabilitation and were tested at 5 time points. The primary outcome measure was Wolf Motor Function Test (WMFT); the secondary measures were Nine‐Hole Peg Test (NHPT), the Fugl‐Meyer Assessment (FMA) of the upper extremity, Stroke Impact Scale, and Modified Rankin Scale (MRS). ResultsCompared with baseline data, both groups showed significant improvements in the primary and secondary outcome measures after 12 months. No significant differences between the 2 treatment groups were found before and after the delayed intervention group received CIMT at 6 months and during the 12‐month follow‐up. Both groups recovered considerably and showed only minor impairment (median FMA score of 64) after 6 months. The early intervention group showed an initially faster recovery curve of WMFT, NHPT, and MRS scores. DiscussionIn contrast to most CIMT studies, our study could not find an effect of CIMT applied 6 months after stroke. Our results indicate that commencing CIMT early is as good as delayed intervention in the long term, specifically in this group of patients who might have reached a ceilin...
