Research and development of needle electromyography exam(NEE) robotic simulator
Currently, training for NEE which always used fellow students or colleagues as objects, cannot reproduce multiple pathological conditions for neurological disorders to simulate real NEE.
Develop a novel simulator with lower cost, higher accuracy and less response time to improve medical students’ skill by needle electromyography exam.
Using camera, curved phantom and ring electrode to localize needle tip. The accuracy of localization was (2.01±1.01 mm) for now. Depend on the needle tip position, electromyography sound could be generated with less response time.
Design a personalized assistive device for improving hand and elbow function in Brachial Plexus Injury (BPI)
Conventional assistive device is not effective enough to improve elbow movement in brachial plexus injury (BPI) patients without pain
To design a soft assistive device that facilitate elbow movement with minimum pain for BPI patients
Testing the painful of the wearer with pain-related evoked potential (PREP) during movement with prototype device
Theoretical study on the principles and effect of interferential current stimulation has not been conducted insufficiently.
To clarify the principle of ICs and investigate the influence of each parameter on stimulation effect for optimizing the effect according to application.
To reach the goal, we simulate nerve response to stimulation using FEM and nerve model.
Segmentation previous to MREPT reconstruction to improve the boundary of the cancerous tissue
The percentage of incorrect diagnosis of prostate cancer is affected from insignificant prostate cancer (IPC).
The MREPT method has been created to develop a higher contrast image by inputting the electrical properties of the tissue, a higher contrast image would allow for the resolution of cancerous tissue by the specialists.
Currently techniques to increase boundary resolution of MREPT is being researched.
Pain relief by nerve fiber selective stimulation based on endogenous opiate theory
Long-term treatment of pain relief by administration of analgesic is likely to lead to dependence.
Analysis of potential distribution in the body by TES and examination of electrical stimulation therapy by simulation of stimulation response.
Structure of finite element model of object part of electric stimulation．
Electrophysiological Models for Motor Recovery
To implement and validate an effective and efficient electrophysiological model using a systematic approach to evaluate electrophysiological factors (macro to micro) in nerve activation for electrical stimulation.
To find optimal therapies for recovering motor functions using Electrical Stimulation.
Results until now
1) Validation of the voltage distribution using a dispersive model by human-equivalent phantoms and simplification to a non-dispersive model of the electric properties of the tissues.
2) Clarification of morphology detail necessary to represent the volume conductor of the model.
3) Experiments of the effect of morphological and dielectric properties of biological tissues using a systematic approach to reduce inter-individual variation.
4) The model implementation has been extended for non brain stimulation effects and electromyography estimation.
An Excitation-Contraction Coupling Simulation Using Transcutaneous Electrical Stimulation
Development of a novel excitation-contraction coupling simulation of the thigh for Transcutaneous Electrical Stimulation.
To find optimal therapies for recovering motor functions using Transcutaneous Electrical Stimulation.
Results until now
To obtain the effect of different parameters (fat thickness, electrode size, etc.) in the Activation Volume (location of nerve activation) for a thigh model (cylindrical representation) and square-electrodes.
