ABSTRACT

The main objective of this study was to understand the technique of Electromyography. In this technique activities of muscles were governed on the basis of generated my electrical signals. Electromyography instrumentation consists of data acquisition unit, Universal interface module, Connector, adaptor and software. Various parameters like chew number, mastication time, total burst duration, total muscle activity, burst duration, inter burst duration, cycle time, muscle activity and amplitude were used for analysing the data acquired during mastication of food at entire mastication, per chew and at three different stages (early, middle and late) of mastication.
