Abstract
Purpose: This study aimed to investigate the use of insoles in patients with temporomandibular joint disorders to assess the function and changes in pain when walking in daily life.
Methods: Sixty-five patients with temporomandibular joint disorder, were selected, with 34 assigned to the control group and 31 to the experimental group. The control group walked more than 7,000 steps per day in their daily life, while the experimental group wore insoles and was instructed to take at least 7,000 steps every day. To evaluate the effect on temporomandibular joint pain, steady-state pain, maximum mouth opening, average pain, and the most severe pain were measured before and after the experiment. In addition, to determine function, mouth opening in a comfortable state, mouth opening pain, and the point of sound and the maximum degree of mouth opening were evaluated before and after the experiment.
Results: After the experiment, pain, mouth opening, and sound points showed significant differences compared to the control group. However, there was no significant difference in the maximum mouth opening range.
Conclusion: The application of air insoles to patients with temporomandibular joint disorder confirmed the function of the temporomandibular joint and its positive effects on pain.
