[Purpose] The improvements in gait of the patients with lower limb disease who used a
temporomandibular joint (TMJ) exerciser were verified. [Subjects and Methods] Eleven
subjects were included. Their mean age was 53.2 years. The lower limb joint angles before
and after using the TMJ exerciser were measured using a gait analyzer. Before the gait
experiment, the TMJ exerciser setting process and one-leg stance balance test (OLST) were
repeated until the balance maintenance time improved. [Results] Because of the OLST, the
mean change in the body center point after the subjects used the exerciser improved from
5.76 mm to 4.20 mm. When the TMJ exerciser was used, the joint angle range of the subjects
approached that of the normal individuals. [Conclusion] According to the gait experiments,
the angles of the subjects’ hips, knees, and ankle joints approached to those of the
normal individuals after the subjects used the TMJ exerciser; however, the results did not
completely match. The changes in the hip, knee, and ankle joint angles were statistically
significant, which confirm the usefulness of the TMJ exerciser.
