To compare the effects of dyad and individual training on the learning of bimanual cup-stacking in individuals with chronic stroke. Twenty participants were divided into dyad and individual groups. The dyad group performed the task in pairs alternating between performing and observing, while the individual group performed individually. On the first day (acquisition phase: AP), allparticipants performed 20 trials. On the following day (retention phase: RP), they performed 10 trials; each participant individually performed five trials without verbal feedback followed by five trials with verbal feedback. The dependent measures were movement time (MT), which was a measure of motor execution, and reaction time (RT), a measure of motor planning. During the initial trials, the dyad group performed the task with longer MT. By the end of the AP their time was significantly shorter At the R, only the dyad group maintained the improved MT of cup stacking. Although the RT was not different between the two groups at the RE, only the RTof the dyad group reduced significantly at the RP compared with block l of the AP CONCLUSION: In individuals with chronic stroke, the dyad training protocol greatly enhanced the execution speed of the bimanual cup-stacking task when compared with the individual training protocol. Planning the task also improves dyad training.
