Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• POC TA

  Percentage of Overlapping Coefficient of the Anterior Temporalis (right and left): A parameter that measures the degree of overlap in electromyographic activity between two muscles or between two conditions, used to assess muscular coordination or symmetry. The higher the percentage, the more synchronized or similar the muscular activity.
