The aim of this study was to determine whether increased muscular tension
disturbs postural equilibrium more when it is asymmetrical. Ten healthy male
subjects underwent a posturographic examination associated with an original uni
and bilateral compressive load paradigm designed to set the active muscular
tension at different controlled levels along each side of the torso. Respiratory
kinematics were recorded by means of two sensing belts. Two electromyographic
pre-tests were used to map out the main motor muscles of the task and to quantify
the level of asymmetry induced by unilateral loads. The posturographic
examination revealed that the mean deviation of the CP along the medial-lateral
axis was significantly greater in unilateral than in bilateral compressive loads.
It was suggested that increased muscular tension along the torso induces a more
disturbing effect on posture when it is asymmetrical.
