Multimodal Physiotherapy Versus Occlusal Splint in Adults With Temporomandibular Disorders

Effect Of A 6-week Multimodal Physiotherapy Programme Versus Occlusal Splint Therapy On Pain, Mouth Opening And Quality Of Life In Adults With Muscular Temporomandibular Disorders: A Controlled Clinical Trial

The aim of this study is to compare the effects of two therapeutic approaches commonly used in the management of muscular temporomandibular disorders (TMD): a multimodal physiotherapy program combining manual therapy and therapeutic exercises, and the use of an occlusal splint during sleep.

This study seeks to determine whether these interventions help reduce pain, improve mouth opening, and enhance oral health-related quality of life in adults with muscular TMD.

Participants will be assigned to one of two groups: one group will receive a six-week multimodal physiotherapy program, while the other will use an occlusal splint nightly for the same period.

Assessments will be conducted at baseline and 48 hours after completion of the intervention. The findings of this study may contribute to improving clinical management and treatment strategies for individuals with TMD.

Inclusion Criteria:

• Individuals of both sexes;
• Aged 18-50 years;
