About this study

Official title: Investigation of the Effects of Limbic System-Oriented Combined Manual Therapy on Pain, Joint Range of Motion, Muscle Strength, Joint Position Sense, Balance, Functional Status, Emotional State, Quality of Life, and Sleep Quality in Temporomandibular Joint Dysfunction

Temporomandibular joint disorders (TMD) are common conditions that may cause jaw pain, limited jaw movement, and reduced quality of life. Individuals with TMD can also experience neck-related problems, balance impairments, emotional changes, and sleep disturbances.

This interventional study aims to investigate the effects of a combined physiotherapy and rehabilitation program in individuals with temporomandibular joint dysfunction. The intervention consists of conventional manual therapy techniques applied to the temporomandibular joint and cervical region, combined with specific manual therapy techniques targeting the limbic system, along with therapeutic exercise applications.

The study will evaluate the effects of this combined treatment approach on pain, jaw range of motion, joint position sense, balance, emotional status, patient satisfaction, and quality of life and sleep in individuals with TMD.

Read the detailed description

Temporomandibular joint dysfunction is a complex condition that affects the masticatory system and is frequently associated with cervical musculoskeletal impairments, altered sensorimotor control, and psychosocial factors. In addition to local biomechanical dysfunctions, individuals with temporomandibular disorders may experience changes in pain processing, emotional regulation, balance, and overall quality of life. These factors highlight the need for a comprehensive rehabilitation approach that addresses both peripheral and central mechanisms.

Physiotherapy and rehabilitation interventions for temporomandibular joint dysfunction traditionally focus on the temporomandibular joint and cervical region using manual therapy techniques and therapeutic exercises. While these approaches are effective in improving physical impairments, emerging evidence suggests that central mechanisms, including the limbic system, may influence pain perception, emotional status, and functional outcomes in individuals with temporomandibular disorders.

This interventional study is designed to investigate the effects of a combined physiotherapy and rehabilitation approach that integrates conventional manual therapy techniques applied to the temporomandibular joint and cervical region with specific manual therapy techniques oriented toward the limbic system, along with therapeutic exercise applications. The combined approach aims to address musculoskeletal, sensorimotor, and emotional components of temporomandibular joint dysfunction within a holistic rehabilitation framework.

Participants diagnosed with temporomandibular joint dysfunction will undergo the intervention program and will be evaluated before and after the treatment period. The study focuses on changes in pain, jaw function, sensorimotor control, balance, emotional status, patient satisfaction, and quality of life and sleep, providing a multidimensional assessment of treatment effects.

By examining the outcomes of this combined intervention, the study seeks to enhance the understanding of integrative physiotherapy strategies in the management of temporomandibular joint dysfunction and to support the development of more comprehensive rehabilitation approaches that consider both physical and emotional aspects of the condition.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Conventional Physiotherapy and Rehabilitation ProgramOther

    The intervention is delivered over a 6-week period. Manual therapy techniques applied to the cervical region and temporomandibular joint, along with supervised jaw exercises, are administered twice per week. In addition, participants perform postural exercises as part of a home exercise program for 6 weeks, 5 days per week, three times per day, with 10 repetitions per exercise. All interventions are administered by a physiotherapist according to a standardized physiotherapy protocol.

  • Limbic-Oriented Manual TherapyOther

    In addition to the conventional physiotherapy and rehabilitation program, limbic-oriented manual therapy techniques are applied over a 6-week period. Three limbic-oriented manual therapy techniques are administered during each session, with each technique applied for an average duration of approximately 3 minutes. These techniques are administered twice per week by a physiotherapist according to the study protocol. The limbic-oriented manual therapy is delivered alongside manual therapy to the cervical region and temporomandibular joint, supervised jaw exercises, and a structured home exercise program.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain Intensity at Rest (Visual Analog Scale)

    Pain intensity at rest is assessed using the Visual Analog Scale (VAS), a 10-cm horizontal line ranging from 0 to 10 cm.

    A score of 0 indicates no pain and a score of 10 indicates the worst imaginable pain.

    Higher scores represent greater pain intensity. The distance from the left end of the scale to the marked point is measured using a ruler and recorded in centimeters (cm).

    Measured: Baseline and after 6 weeks

  2. Pressure Pain Threshold (Algometry)

    Pressure pain threshold is assessed using a handheld pressure algometer. Measurements are performed bilaterally at three anatomical sites: the temporomandibular joint region, masseter muscle, and temporalis muscles, and recorded in Newton (N).

    At each site, three consecutive measurements are taken, and the mean value is calculated for analysis.

    Higher values indicate greater pressure pain tolerance, whereas lower values indicate increased pain sensitivity.

    Assessments are conducted at baseline and at the end of the treatment period.

    Measured: Baseline and after 6 weeks

  3. Cervical Joint Position Sense

    Cervical joint position sense is assessed during flexion-extension, right and left rotation, and right and left lateral flexion movements using target angle tests and the head repositioning test. Flexion, extension, and rotation movements are assessed at mid-range positions (50% of the available range of motion) and at target angles of 10° and 30°. Lateral flexion movements are assessed at target angles of 10° and 20°, as well as at mid-range positions (50% of the available range of motion). During each test, the deviation from the target angle is recorded. The angular error is calculated as the absolute difference between the target angle and the angle achieved by the participant and recorded in degrees (°). Higher angular error values indicate poorer joint position sense, whereas lower values indicate better proprioceptive accuracy. Each test is performed three times with the participant's eyes closed, and the mean value of the three measurements is recorded for analysis.

    Measured: Baseline and after 6 weeks

  4. Temporomandibular Joint Range of Motion

    Temporomandibular joint range of motion is assessed using a digital caliper. Pain-free maximum mouth opening, right and left lateral excursions, and mandibular protrusion movements are measured.

    All measurements are recorded in millimeters (mm) for analysis. Higher values indicate greater mandibular mobility, whereas lower values indicate restricted temporomandibular joint range of motion.

    Measured: Baseline and after 6 weeks

  5. Cervical Joint Range of Motion

    Cervical joint flexion, extension, bilateral lateral flexion, and rotation movements are evaluated using a cervical range of motion (CROM) device.

    Measurements are recorded in degrees (°). Higher values indicate greater cervical mobility, whereas lower values indicate restricted cervical range of motion.

    Measured: Baseline and after 6 weeks

  6. Static Balance (Flamingo Balance Test)

    Static balance is assessed using the Flamingo Balance Test. Participants are instructed to stand on a wooden balance beam and maintain balance on one lower extremity.

    The test is performed on the participant's dominant extremity. Timing begins when the participant achieves single-leg stance, and the participant is asked to maintain balance for one minute without falling.

    During the one-minute period, each attempt to regain balance after a loss of balance is counted.

    The total number of balance attempts recorded during the test constitutes the participant's score.

    Higher scores indicate poorer static balance performance, whereas lower scores indicate better balance control.

    Measured: Baseline and after 6 weeks

  7. Dynamic Balance (Y Balance Test)

    Dynamic balance is assessed using the Y Balance Test. The test is performed in the anterior, posteromedial, and posterolateral directions.

    Participants perform three trials in each direction, and the mean value of the three measurements is calculated for analysis.

    Reach distances are recorded in centimeters (cm). Higher reach distances indicate better dynamic balance performance, whereas lower values indicate reduced balance ability.

    Measured: Baseline and after 6 weeks

  8. Pain Intensity During Chewing (Visual Analog Scale)

    Pain intensity during chewing is assessed using the Visual Analog Scale (VAS), a 10-cm horizontal line ranging from 0 to 10 cm.

    Pain is evaluated separately during chewing of hard and soft food. A score of 0 indicates no pain, and a score of 10 indicates the worst imaginable pain.

    Higher scores represent greater pain intensity. The distance from the left end of the scale to the marked point is measured using a ruler and recorded in centimeters (cm).

    Measured: Baseline and after 6 weeks

  9. Pain Intensity During Biting (Visual Analog Scale)

    Pain intensity during biting is assessed using the Visual Analog Scale (VAS), a 10-cm horizontal line ranging from 0 to 10 cm.

    A score of 0 indicates no pain, and a score of 10 indicates the worst imaginable pain.

    Higher scores represent greater pain intensity. The distance from the left end of the scale to the marked point is measured using a ruler and recorded in centimeters (cm).

    Measured: Baseline and after 6 weeks

  10. Pain Intensity During Night-Time (Visual Analog Scale)

    Night-time pain intensity is assessed using the Visual Analog Scale (VAS), a 10-cm horizontal line ranging from 0 to 10 cm.

    A score of 0 indicates no pain, and a score of 10 indicates the worst imaginable pain.

    Higher scores represent greater pain intensity. The distance from the left end of the scale to the marked point is measured using a ruler and recorded in centimeters (cm).

    Measured: Baseline and after 6 weeks

  11. Pain Intensity During Yawning

    Pain intensity during yawning is assessed using the Visual Analog Scale (VAS), a 10-cm horizontal line ranging from 0 to 10 cm.

    A score of 0 indicates no pain, and a score of 10 indicates the worst imaginable pain.

    Higher scores represent greater pain intensity. The distance from the left end of the scale to the marked point is measured using a ruler and recorded in centimeters (cm).

    Measured: Baseline and after 6 weeks

  12. Pain Intensity During Eating (Visual Analog Scale)

    Pain intensity during eating is assessed using the Visual Analog Scale (VAS), a 10-cm horizontal line ranging from 0 to 10 cm.

    A score of 0 indicates no pain, and a score of 10 indicates the worst imaginable pain.

    Higher scores represent greater pain intensity. The distance from the left end of the scale to the marked point is measured using a ruler and recorded in centimeters (cm).

    Measured: Baseline and after 6 weeks

  13. Temporomandibular Joint Dysfunction Severity (Fonseca Anamnestic Questionnaire)

    Temporomandibular joint functional status is assessed using the Turkish version of the Fonseca Anamnestic Questionnaire. The total score ranges from 0 to 100, with higher scores indicating greater severity of temporomandibular joint dysfunction.

    Measured: Baseline and after 6 weeks

  14. Mandibular Functional Impairment (Mandibular Function Impairment Questionnaire)

    Mandibular functional status is assessed using the Turkish version of the Mandibular Function Impairment Questionnaire. The total score ranges from 0 to 68, with higher scores indicating greater functional impairment

    Measured: Baseline and after 6 weeks

Secondary outcomes (9)
  1. Chewing Quality (Visual Analog Scale)

    Chewing quality is assessed using the Visual Analog Scale (VAS), a 10-cm horizontal line ranging from 0 to 10 cm.

    A score of 0 indicates very poor chewing quality, and a score of 10 indicates excellent chewing quality.

    Higher scores represent better chewing quality. The distance from the left end of the scale to the marked point is measured using a ruler and recorded in centimeters (cm).

    Measured: Baseline and after 6 weeks

  2. Patient Satisfaction With Treatment (Visual Analog Scale)

    Patient satisfaction with the treatment is assessed using the Visual Analog Scale (VAS), a 10-cm horizontal line ranging from 0 to 10 cm.

    A score of 0 indicates "not satisfied at all," and a score of 10 indicates "extremely satisfied." Higher scores represent greater treatment satisfaction. The distance from the left end of the scale to the marked point is measured using a ruler and recorded in centimeters (cm).

    Measured: At the end of the treatment period (6 weeks)

  3. Postural Assessment

    Postural assessment is performed bilaterally using a measuring tape. Linear distances are measured between predefined anatomical landmarks and recorded in centimeters (cm). Measurements are obtained from both sides of the body for analysis.

    Measured: Baseline and after 6 weeks

  4. Deep Cervical Flexor Muscle Strength

    Deep cervical flexor muscle strength is assessed using a Stabilizer Pressure Biofeedback unit.

    The pressure generated by the participant during the test is recorded in millimeters of mercury (mmHg).

    The assessment is performed under two conditions: without visual feedback and with visual feedback, during which the manometer is visible to the participant.

    In both conditions, participants are instructed to perform a craniocervical flexion movement, and the corresponding pressure values are recorded for analysis.

    Higher pressure values indicate greater deep cervical flexor muscle activation and strength.

    Measured: Baseline and after 6 weeks

  5. Neck Disability

    Neck-related disability is assessed using the Turkish version of the Neck Disability Index (NDI) questionnaire.

    The total score ranges from 0 to 50, with higher scores indicating greater neck-related disability and functional limitation.
