Deficits in interlimb coordination(IC) contribute to the functional disability in stroke patients. Addressing IC deficits after stroke has been somewhat overlooked in the realm of stroke interventions. Our goal is to develop a robotic therapy protocol to improve IC for bimanual tasks and to assess changes in IC due to therapy. We evaluated the metrics of phase difference(PD), goal synchronization(GS), task completion time(TCT), % movement overlap(%MO) to determine which are most sensitive to IC on both symmetric and asymmetric functional tasks (e.g., drink and feed). We assessed IC for able-bodied and strokes. We showed PD, TCT, and %MO to be sensitive to differences in IC across subject groups. PD was more sensitive in the symmetrical task while TCT and %MO were more sensitive in the asymmetrical task.

Disney produced a television show in the mid 1990s called Gargoyles. It's a great show and I'm a big fan. A few years ago Disney started to release the show on DVD. The last release was of season 2, volume 1. That was two years ago. Volume 2 has not been released. Why? Poor sales. So if you should find yourself wanting to support my work, instead I ask you pick up a copy of season 2, volume 1. It's a great show and you might find yourself enjoying it.
