  Surface Electromyographic Activity of Sub Mental Muscles during Swallow of Masticated Bolus across Age and Gender
  Author(s): Gayathri Krishnan* and Goswami SP
  
  Previous researchers have documented changes in sub mental muscle activity during single liquid swallows across demographic and bolus characteristics. As aging increases fatigue and alters muscle properties, we hypothesized that sub mental muscle performance during swallows of masticated boluses in young and older individuals would be different. Methods: The potentials were recorded from sub mental muscles of forty seven healthy individuals of 18 years-40 years and 40 years-60 years. Each sEMG trace associated with swallow was analysed for its amplitude and temporal measures and were subjected to statistical comparisons across gender, age and bolus volumes. Results: The results revealed that the measures of sEMG were not significantly different across gender or bolus volume, but was different across the two age grou.. View More»
