ELECTROMYOGRAPHIC (EMG) INVESTIGATION OF MASSETER MUSCLE ACTIVITIES ACQUIRED IN DIFFERENT SESSIONS DURING CHEWING OF VARIOUS INDIAN FOOD PRODUCTS

摘要

The objective of this study was to investigate the correlations between electromyographic (EMG) mastication recordings acquired in different sessions during chewing of various Indian food products.Three different sessions were selected for the study viz.one morning session and two evening sessions.Four human subjects participated in the study who were served with five different textured Indian food products.Fifteen mastication variables were obtained by analyzing the data acquired from each EMG session.Correlation studies were conducted for these EMG variables acquired during different sessions.It can be inferred that significant (p≤0.05) correlations exist between EMG variable acquired in the sessions conducted at the same time as well as those conducted at different timings.This indicates that a subject’s EMG recordings are reproducible during various sessions.
