Gedetailleerde beschrijving
The purpose of this study is to assess the Effect of Compression and Decompression Technique on the Temporomandibular Joint on masseter muscle tone and stiffness (always assessed on the right side). Muscle properties will be evaluated using the Myoton device (Myoton AS, Tallinn, Estonia), a non-invasive instrument that measures biomechanical and viscoelastic properties of muscles, such as stiffness and tone (the parameters used in the results).
In addition, maximum mouth-opening width will be assessed by measuring the distance between the upper and lower central incisors using a universal caliper, recorded in millimeters.
These outcomes will be compared with a control condition consisting of cranial listening touch without therapeutic intent .
The study will include asymptomatic adults without diagnoses of systemic inflammatory diseases, cardiovascular diseases, respiratory diseases , central nervous system disorders, or rheumatic pathologies. Additional exclusion criteria include: use of fixed orthodontic appliances within the past 3 months; visual impairment affecting balance or proprioception; history of maxillofacial surgery; trauma to the cranial or cervical region within the last 6 months ; ongoing pharmacological treatments that may interfere with muscle tone or pain perception (e.g., muscle relaxants, tricyclic antidepressants, benzodiazepines) and third/fourth year osteopathy students.
Measurements of the tone/stiffness of the masseter muscle and maximum mouth opening width will conducted before, immediately after the intervention and one week later the study will be repeated in each participant.

Placebo-vergelijker: Control group
In the control group, cranial listening touch without therapeutic intent using the par la voute hold was performed during 30 seconds.
|
Cranial listening touch without therapeutic intent consists of, with the patient in the supine position and the investigator at the head of the bed, the investigator placing bilateral contacts on the patient's skull with the first fingers in contact with each other, without contacting the skull, the second fingers on the greater wing of the sphenoid, the third fingers anterior to the ear, the fourth fingers posterior to the ear, and the fifth fingers in contact with the squamous part of the occipital bone. In addition, after placing the contacts, the investigator asks the patient not to contact the maxillary teeth with the mandibular teeth. |

Experimenteel: Temporomandibular Compression and Decompression Technique
The intervention consisted of two phases: The first one consisting in mandibular compression, applied for 30 seconds.
The second phase is applied right after, consisting in mandibular decompression, applied for 30 seconds.
|
The temporomandibular joint compression and decompression technique consists of, with the patient in the supine position and the investigator at the head, hooking the middle fingers beneath the angles of the mandible while the basal joints cover the joints and the palms cover the ears and temporal regions.
First, a light cranially-directed pressure is applied to the mandible for 30 seconds to release restrictions and stretch the intracranial membrane.
Subsequently, the vector is reversed, and a gentle caudally-directed traction is applied for another 30 seconds to free the joint space."

Maximum Mouth Opening Width
Tijdsspanne: Immediately after the intervention. Since the protocol has two interventions, the total time frame is one week.
|
For the assessment of the maximum mouth opening width was measured the distance between the upper and lower central incisors was measured in millimeters (mm) using a universal caliper.
|
Immediately after the intervention. Since the protocol has two interventions, the total time frame is one week.

|
Masseter Muscle Tone
Tijdsspanne: Immediately after the intervention. Since the protocol has two interventions, the total time frame is one week.
|
The assessment of masseter muscle tone was performed using Myoton (Myoton AS Talin, Estonia), a non-invasive approach to comprehensively evaluate the biomechanical and viscoelastic properties of muscles.
Muscle tone is calculated using the maximum frequency of oscillation and tissue deformation detected by the transducer (Hz).

Masseter muscle stiffness
Tijdsspanne: Immediately after the intervention. Since the protocol has two interventions, the total time frame is one week.
|
The assessment of masseter muscle stiffness was performed using Myoton (Myoton AS Talin, Estonia), a non-invasive approach to comprehensively evaluate the biomechanical and viscoelastic properties of muscles.
Muscle stiffness is calculated based on equations calculated from the acceleration of the testing probe during oscillations (N/m).
