Constraint-induced Movement Therapy (CIMT) presented robust evidence on increasing the amount and the quality of the paretic upper extremity (UE) functional use in daily situations of individuals with brain injuries (e.g. stroke, traumatic brain injury). The UE CIMT protocol consists of 4 components: 1) repetitive and intensive training; 2) motor training following shaping principles; 3) application of a groups of behavioral strategies called transfer package (TP), and 4) prolonged use of a restriction device on the non-paretic (or less affected) UE.
