A. Arulkumar* and Dr. P. Babu

ABSTRACT

The magnitude of muscle force is important for analyzing joint loading in Biomechanics and many applications like Ergonomics, Biofeedback, Rehabitation and Sports medicine. But it cannot measure by directly. In this study, we present the procedure of acquiring EMG signal to measure Muscle force by Non-invasive and Invasive method. The Surface Electromyography is the Noninvasive (not inserting into muscle) and Needle Electro myography is Invasive (Inserting into muscle) method. The first sections in this document cover technical aspects such as Needle EMG inspection, types of needle electrode, How to insert the needle, Patient preparation, Needle movement, muscle selection, Examining resting muscle and contracting muscle. The second section covers features of Surface EMG including types, Multichannel SEMG and Electrode placements. Finally we compared both the methods and discussed about estimating muscle force by EMG magnitude.

Keywords: Electromyography, Needle Electrode, Surface Electrode, Multichannel SEMG and Muscle force.
