Research summary

Functional deficits after stroke are common problems both in Brazil and in the UK.

As an attempt to improve rehabilitation and reduce its costs, robot-aided therapy

(RAT) has been developed in the last two decades. However, meta-analyses of

clinical trials with RAT revealed a limited transfer to performing common bimanual

tasks. This may be due to the challenges of emulating bimanual tasks in a virtual

environment, thus RATs focussed training only on the affected arm. Therefore, the

Human Robotics Group (HRG) at Imperial College recently developed the SITAR

system for task-oriented-training, which is composed of a force sensitive touch

screen table and instrumented objects. Instead of interacting with a virtual

environment as with most RAT systems, patients interact with real objects by

executing daily tasks through playing computer-controlled rehabilitative games.

We claim that this system can be used to improve bimanual rehabilitation using

appropriate haptic and visual feedback and dedicated assessment. This project

will help us establishing a partnership between the Robotic Group at the Federal

University of Sao Carlos (UFSCar) in Brazil and HRG in the UK, with the goals to:

i) develop bimanual objects used in daily tasks, and ii) integrate them to SITAR at

UFSCar. Evaluation will be carried out in iii) experiments with healthy subjects,

which will provide control data for comparison with iv) a pilot trial carried out with

stroke survivors in both countries.
