Effects of a Training Oral Device (Custom Splint) Adjusted Using Electromyography for the Balance Between the Masseter and Temporal Muscle in Elite Military Paratroopers.

Comparative Study in Professional Paratroopers Between Occlusion and Postural Condition

The aim of this prospective, longitudinal observational study is to evaluate the influence of the use of sports splints on the muscular activity of the stomatognathic system and cervical mobility in adult sport parachutists.

The main research questions are: Does the use of a sports splint modify the electromyographic activity of the masticatory muscles during functional movements? Does it produce changes measurable by accelerometry?

The researchers will compare the records obtained with and without the sports splint in order to determine whether the use of this device produces changes in the neuromuscular activity of the stomatognathic system and in cervical mobility.

Participants will perform the following tasks during the evaluation:

Recording of electromyographic activity of the masticatory muscles using surface electromyography.

Measurement of cervical movements using an accelerometer. Performance of functional cervical movements (flexion, extension, lateral inclination, and nodding) under conditions with and without the sports splint.

Inclusion Criteria:

• Athletes aged 18 years or older
• good oral health -no history of cardiovascular disease or diabetes -
• oral hygiene habits of at least two brushings per day.

Exclusion Criteria:

Poor oral hygiene periodontitis history of recent dental trauma.
