Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in each group (arm 1, 2 an 3) will deliver face to face intervention in 3 sets of 10 minutes manual therapy technics in 7 days interval (10 minutes session once a week for a 3 weeks). Each session will be performed by the same physiotherapist (early stage physiotherapist who passed some courses in craniofacial therapy). Interventions will occur at Musculoskeletal Elastography and Ultrasonography Laboratory, Institute of Physiotherapy and Health Sciences, The Jerzy Kukuczka Academy of Physical Education in Katowice. POLAND.

Arm 1 - Extraoral Therapy
- 30 finger movements along the fibers of the masseter muscle from the outside – along the belly of the masseter muscle from the zygomatic arch to the angle and lateral surface of ramus of mandible.
- 15 finger movements along the zygomatic arch (from nose to lateral)
- 15 finger movements along the fibers of musculus temporalis
- 15 finger movements along the ramus of mandible- submandibular region

Arm 2 - Intraoral Therapy
- 30 finger movements along the fibers of the masseter muscle from the inside- The therapist's thumb inside the patient's mouth, the rest of the fingers on the outside of the cheek. Therapist in disposable gloves.
- 15 seconds pressure of the Lateral Pterygoid muscle at 4 different angles (15 seconds each)- the index finger upward and backward past the upper last mollar x 2

Arm 3 - Extraoral and intraoral Therapy
- 15 finger movements along the fibers of the masseter muscle from the outside – along the belly of the masseter muscle from the zygomatic arch to the angle and lateral surface of ramus of mandible.
- 15 finger movements along the zygomatic arch (from nose to lateral)

- 15 finger movements along the ramus of mandible- submandibular region

Outcomes

Thickness of the masseter muscle [in mm]

Thickness of the masseter muscle will be assessed using USI Aixplorer (Product Version 12.2.0., Software Version 12.2.0.808, Supersonic Imagine, Aix-en-Provence, France), linear-array transducer (2–10 MHz; SuperLinear 10– 2, Vermon, Tours, France)

Elasticity of the masseter muscle [in kPa]

Elasticity of the masseter muscle will be assesed using USI Aixplorer (Product Version 12.2.0., Software Version 12.2.0.808, Supersonic Imagine, Aix-en-Provence, France), linear-array transducer (2–10 MHz; SuperLinear 10– 2, Vermon, Tours, France)

Secondary outcome [1] 419109 0
Dynamic stability test Y-Balance Test [cm, asymmetry]


The device consists of a single central plastic plate and three attached tubes arranged in anterior, posteromedial and posterolateral positions. A measure is positioned on each of the tubes, with an interval of 0.5 cm. The subjects, while standing on one leg (barefoot) in a central location on the Y-Balance Test instrument, with hands placed on the wing of ilium, will be ask to move the pointer as far as possible, using the lower limb opposite to the support limb, in three directions e anterior, posteromedial, posterolateral.” - „Reliability and number of trials of Y Balance Test in adolescent athletes” P.Linek et. al. 2017

2. Romberg’s test on the Platform Human Balance [percent,cm,cm/s]

For evaluation of dynamic stabilization: Stability score (%), path leght (cm), average velocity (cm/s)
„the patient is asked to remove shoes and stand with both feet together on the platform. Next, the examiner instructs the patient to hold his/her arms next to the body or crossed in front of the body. The first stage of the test involves asking the patient to keep their eyes open while the examiner assesses the patient's body movement relative to balance.
The second stage involves instructing the patient to stand erect with their eyes closed while the examiner notes any balance impairment for a duration of one minute. Swaying of the body may be observed. However, this indicates the proprioceptive correction of balance for the lack of visual or vestibular compensation available. The Rhomberg test is positive when the patient has a loss of balance with their eyes closed. Loss of balance can be defined as increased body swaying, foot movement in the direction of the fall, or falling

Tekscan Strideway [cm, m/s, kg]

For evaluation of human gait and postural stability.
Step length - (cm), gait velocity - (m/s), Force - (kg) will be assesed.


The provided software automatically reads from the physical sensors in the mat and performs calculations to derive different gait parameters such as step length - (cm), gait velocity - (m/s), Force - (kg)

All components will be assessed as a composite secondary outcome
