Figure 5.

Activation of triceps brachii with respect to planes and devices. A significant (p = 0.004) interaction was found between the planes and the devices. The frontal plane provided significantly greater triceps brachii activation for the double oscillating device than the sagittal plane (p = 0.004).

Asterisk (*) represents statistical significance of p < 0.05. Squares with full lines represent double oscillating devices (DOD) whereas circles with intermittent lines represent single oscillating devices.
