Gait changes after using a temporomandibular joint exerciser in patients who underwent lower limb joint surgery

Abstract

[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.

Arthroscopic treatment of bilateral mandibular condylar cysts and associated osteoarthritis of the temporomandibular joints in a horse

“…It seems an enormous “leap of faith” to provide local analgaesia to the TMJ and have an effect on a distant site, and yet conversely there are descriptions of the effect of hindlimb pain on bit contact under saddle (Dyson, 2013). Similarly, there have been numerous human studies on the neuromuscular effects of intra‐oral splints (muscular strength, golf‐club swing, gait and elite rifle shooting) as well as reports detailing the correlation between TMJ disease and vertigo in elderly patients (Chung et al., 2016; Dunn‐Lewis et al., 2012; Pae et al., 2013). Review articles have also concluded that dental occlusion and/or TMJ status have an influence on balance, centre of gravity fluctuation, gaze stability and physical performance along with physical fitness (Moon & Lee, 2011).…”

Origini, forma e (dis)funzioni dell’apparato masticatorio in Homo sapiens

“…Importante è la correlazione tra la muscolatura masticatoria e quella cervicale: nei movimenti craniali e mandibolari queste due articolazioni interagiscono regolandosi reciprocamente; la presenza di patologia dell'ATM si correla con l'angolo fra C7 e il piano orizzontale: la posizione della testa è più avanzata in pazienti con disturbi all'ATM rispetto a un gruppo di controllo (Lee 1995). In pazienti con patologia articolare degli arti inferiori, modificando il rapporto cranio-mandibolare, ad esempio con l'uso di un bite, si può normalizzare l'arco di oscillazione (comunemente ROM, range of motion) dell'articolazione coxofemorale durante il cammino (Chung 2016).…”

Developing an Accessibility Metric for VR Games Based on Motion Data Captured Under Game Conditions

“…Most commonly, motion capturing is used as a quantitative measure to compare changes in an identical or at least very similar motion between conditions or participants. Chung et al (2016) used their motion capturing system to investigate potential improvements in gait after the use of an exercise machine for people that underwent surgery on their lower limbs. They had the patients walk a distance of 5 m with and without the exercise device and calculated joint angles from the captured motion data for one full gait cycle.…”
