The O splint overall reduced BVF and stiffness. This decrease may reflect a lessening of the normal load placed upon the joint during functional activities. The increase of BVF in the anterior cube suggests that the joint load may have shifted anteriorly in this group. Combining this finding with previously collected EMG data (Sindelar et al, 2003) indicates that functional load not only moved anteriorly but a loss of translational motion during function also occurred. This alteration of loading may help explain the increased development of DJD signs in the splinted groups.
