Figure 4.

Activation of forearm flexor muscle group with respect to planes and devices. A significant (p = 0.0054) interaction was found between the planes and the devices. The transverse plane provided significantly greater forearm flexor muscle group activation with double oscillating device than the sagittal plane (p = 0.005).

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.
