Specification, design and clinical evaluation of applications for use in occupational therapy developed on a tactile table allowing interaction and manipulation of tangible and instrumented ecological objects for adult and pediatric rehabilitation – ErgoTact

Submission summary

Stroke is the leading cause of disability in adults. The annual incidence is 100 to 300/100 000. In 60 % of cases, patients retain sensory and/or motor sequelae at the upper limb. This results in a loss of autonomy in all activities of daily living such as dressing, bathing or feeding. Improving capacity gripping is a major challenge of the post- stroke rehabilitation with a high social impact.
Many techniques essentially allow limited rehabilitation for recovering elbow or shoulder function. Gripping abilities are not always taken into account, as sensitive information from the surface of objects. It is necessary to develop new rehabilitation techniques to improve motor functional recovery of the upper limb in stroke patients.
Some recent studies show that interactive tables are interesting materials for rehabilitation and occupational therapy. These interactive digital environments, provide patients with a variety of exercises that helps to dramatically increase their motivation, with a strong impact on their motor performance. Interactive tables also allow the interaction within the digital world with real objects that can be handled and moved on the table. However, these objects are generally mostly abstract objects (as cubes for example). A major step forward would be to use real objects from everyday life and provide them with a «skin touch " to capture the positions of the fingers and the forces exerted on the object. This sensor could be used to finely and quantitatively analyze the motor strategies of the patients (finger positioning and forces exerted on the objects) and to take this information into account for rehabilitation exercises .
In this context, the Ergotact project proposes to design, develop and test rehabilitation sequences for the assessment and training of upper limb capacities handling real objects with measurement capabilities of effort and feedback. This project also relies on the use of serious games which will be designed not only to improve the motivation of the patients, but also to deliver biofeedback in a fun way about their performance or in response to potential incorrect movements . Ergotact will facilitate learning or reprogramming sequences of the movements required to perform the requested activity. Developments will be evaluated within a longitudinal clinical evaluation at Raymond Poincaré Hospital in Garches .
