Core exercises elevate trunk stability to facilitate skilled motor behavior of the upper extremities.

Objective: The purpose of this study was to investigate the influence of core exercises on upper extremity function relative to skilled motor behavior and postural sway.

Method: We examined the effects of core exercises on the skilled motor behavior and postural sway of 40 healthy students who were assigned randomly to the core exercise group or the control group. Independent variable is extent of exposure to core exercise and dependent variables are skilled motor behavior and postural sway.
