Investigation and identification of activation regions for TES grasp with electrode arrays


Raffael La Fauci, Christoph Wegmüller

Semester/Bachelor Thesis, SS 07

For many years, scientists have been searching for treatments to restore functional movements, such as walking or grasping, of people with neurological disorders. Functional Electrical Stimulation (FES) is one way to support people with such disorders.
The FES system has been developed at the IfA with the aim to improve paralyzed people's capability to grasp. By applying current pulses on pairs of electrodes, the finger and wrist exors and extensors can be selectively stimulated. This way a significant improvement to support grasping can be observed. At the beginning, the system had only one electrode array and could not be easily configured. Therefore, new electrode arrays and a new control software had to be developed. The task consists in investigating and identifying the activation regions of the finger and wrist exors and extensors. The newly developed software has produced promising results so far. It will now be used to find activation regions with the aim of activating them simultaneously. This software is able to activate up to eight activation regions at the same time, which is a significant progress in this research area.
