Jaw Muscle Electromyographic Response to Whole-Body Postural Perturbation.

ABSTRACT:

Background

While whole-body postural control requires integration of the sensorimotor system, the involvement of jaw muscle activity in this control remains unclear.

Objective

This study aimed to clarify the relationship between jaw muscle activity and whole-body postural stability by measuring jaw-opening and closing muscle activities, as well as whole-body postural sway during postural perturbations with two different levels of predictability.

Methods

Twelve healthy adults (7 males, 5 females; median age 21.0 years) underwent vertical perturbations by holding a bar at shoulder height. In the cued condition (C-cond), the participants were given a 3-s countdown before the bar was loaded with 3% of their body weight, whereas in the uncued condition (U-cond), the load w
