CIMT is a well-known intervention that combines behavioral and physical training by requiring a patient to use the impaired limb when the less affected limb is immobilized, usually by placing the less affected hand in a mitt that prevents opposition and grasp or, alternatively, by placing the entire UE in a sling. In the EXCITE trial, participants were randomly assigned to either the immediate (3–9 months poststroke) or delayed (over 1 year later) groups. Approximately half of those participants randomized to the delayed group received traditional physical therapy or alternative therapy treatments not associated with the EXCITE trial.5 (link),13 (link) During the training period, all participants donned a safety mitt on their less impaired UE for 90% of their waking hours for 14 consecutive days. On weekdays (10 days), they received adaptive task practice (ATP) and repetitive task practice (RTP) progressing up to 6 hours. ATP is a form of behavioral training, also referred to as “shaping,” while RTP is less structured emphasizing repetition of common tasks such as eating or grooming for typical intervals of 15 to 20 minutes.5 (link)
