Efficacy of Scapulothoracic Exercises on Postural Stability, Proprioception, Muscular Features and Mandibular Functions

The goal of this Randomized, Double-Blind, Clinical Trial is to investigate the effects of scapulothoracic exercises on postural stability, muscle strength, muscular endurance, mandibular functions and proprioception in sedentary individuals aged 18-45 years with head forward posture and temporomandibular joint dysfunction (Cranio-Cervico-Mandibular Malalignment). The main questions it aims to answer are:

• Do Scapulothoracic exercises given in addition to cervical posture exercises have an effect on postural stability, proprioception, muscle strength, muscular endurance and mandibular functions in individuals with Cranio-Cervico-Mandibular malalignment?

Researchers will compare conventional neck exercises (control group) and scapulothoracic exercises applied in addition to conventional neck exercises (treatment group) to see the effects of scapulothoracic exercises on the neck and jaw area.

About this study

The investigators aimed to investigate the effects of scapulothoracic exercises on postural stability, muscle strength, muscular endurance, mandibular functions and proprioception in sedentary individuals aged 18-45 years with cranio-cervico-mandibular malalignment including head-first posture and temporomandibular joint dysfunction problems.

Treatment and study plan

Exercises

Other

For control group; Cervical conventional exercises. For treatment group; scapulothoracic exercises including strengthening, proprioceptive and stabilization exercises in addition to cervical conventional exercises

Primary outcomes

  1. Postural Stability

    Time frame: Postural stability was measured at 3 different times (before treatment, 8 weeks after treatment, 12 weeks follow up). The average measurement time for each participant was 5 min.

    Five different data were obtained: the peripheral length value of the total sway degree (°) made on the device during balance, the percentile value of the area gap (%) showing the percentage of the area drawn according to the reference circle, the sway velocity value (°/sec), the average values (°) reached in the sway in the antero-posterior (AP) and medio-lateral (ML) directions.

  2. Joint Position Sense

    Time frame: Proprioception measurements were made at 3 different times (before treatment, 8 weeks after treatment, 12 weeks follow up). The mean measurement time for mandibular position sense for each participant was 8 min. Cervical joint position sense measure

    Mandibular and cervical joint position sense measurements were made.

Secondary outcomes

  1. Muscle Strength

    Time frame: Muscle strength measurements were made at 3 different times (pre-treatment, 8th week post-treatment, 12th-week follow-up). The temporomandibular joint depressor muscle strength measurement time for each participant lasted 3 minutes. The st

    Isometric muscle strength test will be performed on TMJ depressor muscles and cervical region muscles.

  2. Endurance Measurement of Deep Neck Flexor Muscles

    Time frame: Muscular endurance of deep neck flexors was measured at 3 different times (pre-treatment, 8th week post-treatment, 12th week post-treatment follow-up). It took an average of 15 minutes for each participant.

    The muscular endurance measurement of the deep neck flexors will be made using the "craniocervical flexion test" and a stabilizer device.

  3. Mandibular Function Disorder Questionnaire (MFBA)

    Time frame: Mandibular Function Disorder Questionnaire (MFBA) was measured at 3 different times (pre-treatment, 8th week post-treatment, 12th week post-treatment follow-up). It took an average of 2 minutes for each participant.

    It is used to evaluate the level of impairment in jaw functions in patients with TMED.

Other outcomes

  1. Body Mass Index

    Time frame: Body Mass Index was measured at pre-treatment period.

    Height and body weights were measured to measure the body mass index of the participants.
