Background Although many various types of metatarsophalangeal foot-toe orthoses have been applied to reduce biomechanical problems during gait in individuals with Morton foot syndrome (MFS), few studies have verified influences of applying foot-toe orthosis for MFS on three-dimensional (3D) movements of the pelvic segment. Purpose To determine kinematic 3D pelvic motion using a 3D motion analysis system, including two force platforms with and without a foot-toe orthosis condition. Study design A cross-sectional and repeated-measures study design. Methods Kinematic pelvic data were obtained during free gait from twenty-five individuals with MFS. A three-dimensional motion capture system was used to obtain pelvic motion data with and without foot-toe orthotic conditions. Repeated-measures analysis of variance was used to verify the influence of each orthotic condition on kinematic values. Results Significant differences on the pelvic range of motion (ROM) values of the maximal depression (F=6.447, p=0.008), total ROM in coronal plane (F=4.665, p=0.021), and total ROM in the transverse plane (F=3.990, p=0.038) were found according to orthosis conditions. However, there were no significant differences in any maximal pelvic ROM values between the lower limb sides (p>0.05). In addition, there were also no interactive effects between the orthosis conditions and the foot sides in any of the pelvic maximal ROM variables (p>0.05). Conclusions Applying the foot-toe orthosis for MFS increased the pelvic stability as a reduction of maximal pelvic coronal and transverse movement during gait compared to baseline barefoot walking condition. Therefore, clinical interventions using relatively easy-to-apply foot-toe orthoses are needed to manage and prevent future development of various musculoskeletal deformities and pain in individuals with MFS.
