Myoelectric control with surface EMG signal has achieved great success in clinics, but only limited to the control of 2-Degrees-of-freedom prosthesis. With the appearance of multiple-channel and high-density EMG system and the advances of pattern recognition technology, it becomes possible to control a multi-degree smart prosthesis using EMG signals. However, it requires high performance EMG systems...
A new method is reported for human muscle force modeling based on the fuzzy theory. First, a Hill-based muscle force model was built. The muscle activation parameters were ascertained by fuzzy inferential algorithm as the input of the Hill-based muscle force. Then, a weightlifting motor task was implemented. Four channels of electromyography signals and twelve virtual markers motion data were collected...
The purpose of this study was to evaluate the pre orthodontic trainer appliance efficiency in patients with orthodontic abnormalities. The evaluation was done during sucking on an empty straw. Ten patients (male and female), between 8 and 12 years of age, were examined. Electromyogram recordings were made at the initial stage of myofunctional therapy. The electrodes were placed on the right anterior...
