| Outline of Annual Research Achievements |
Transcutaneous electrical stimulation (TES) generates an electric field that can yield a muscle contraction. In this way, TES can be used for regaining impaired functions, therapy, and medical diagnosis test (nerve conduction study) of the neuromuscular system. The muscle response caused by TES depends on the electrophysiological characteristics of the tissues. To improve rehabilitation and medical evaluation, a simulation model would provide the framework to select the stimulation parameters.
In my past research, the objective was to integrate the electrical properties of tissues with the motor neurons activation using a dispersive model of the tissues behavior. This novel model was used to clarify the influence of the geometric and electrical factors of tissues and electrical stimulation parameters in the muscle recruitment and nerve activation at the macro level.
During this year, I worked on the refinement of the experimental measurements for model validation and the simulation model (error of the voltage distribution was reduced to 2% in a human tissue-like phantom). Also, an electromyography model was included and validated to investigate muscle activation for future diagnosis of nerve condition. Moreover, the results were extended to brain stimulation, and a new electroencephalography electrode was designed. Finally, a new method was proposed to measure the 3D-position of the needle for muscle diagnosis based on our computation model of the voltage distribution, as part of the development of the electrophysiological based robotic simulator for nerve conduction study.
