Abstract The ability to successfully manipulate object is crucial for maintaining an independent lifestyle. It depends on the individual's capability to prevent object slippage by controlling and coordinating the forces applied against the digits-object interaction. Many neurological diseases affect the ability to manipulate objects and, also, the force control and coordination. For instance, individuals who suffered a cerebral vascular accident (CVA) have difficulties during the execution of daily living activities such as dressing up or feeding themselves as well as have poor control and coordination of forces acting on the digits-object interaction. However, as far as we know there was no study which systematically investigated the effect of the side of the cerebral lesion (right or left hemisphere) on the task manipulation performance and on the control and coordination of hand forces. This investigation is important since it has been found that the left and right brain hemisphere control different upper limb functions and because the results could indicate new pathways towards rehabilitation of hand function. Therefore, the aim of this project is to examine the effect of the side of the brain lesion on the performance and on the control of manipulation tasks in individuals post left and right CVA. To reach this aim, we will test post CVA individuals (and healthy controls) in traditional hand function tests (Jebsen & Taylor Hand Function Test, Nine-Hole Peg Test, Power Grip Strength, and Pinch Grip Strength) and during simple manipulation tasks using a instrumented handle (free and fixed ones) which will be used to assess the relationship between the forces involved in object manipulation and will provide new understandings about the neural control mechanisms involved in hand function. | |
