Detailed Description
60 subjects with TMD, according to the Research Diagnostic Criteria, will be included in the study after voluntary consent form will be filled out. Subjects will randomly be divided into 3 groups according to the order.
Home Exercise (n=20) will be the Group 1, Home Exercise combined with Manual Therapy (n=20) will be the Group 2, and Orofacial Myofunctional Therapy combined with Home Exercise and MT treatment (n=20) will be the Group 3.
Group 1 will include educational training program about parafunctional activities of TMD disorders and active exercises for masticatory and neck muscles with 10 repetitions, 3 times a day, and for 10 weeks.
Group 2 will receive home exercise training program and manual therapy program which is planned to last 30 minutes; will be applied twice a week, for 10 weeks.
Group 3 will include stretching and strengthening of the tongue muscles, tongue rotation exercises, effortful swallowing, strengthen the hyoidal muscles, which is planned to last 40 minutes, will be applied twice a week, for 10 weeks.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Home Exercise Home Exercise program includes educational training program about parafunctional activities of patients having oral dysphagia with temporomandibular disorders. Program includes stretching and strengthening of masticatory and neck muscles and posture exercises as well as diaphragmatic breathing exercises. |
Procedure: Home Exercise
Educational training program about oral dysphagia in patients with temporomandibular disorders.
|
| Active Comparator: Manual Therapy Combined with Home Exercise Manual Therapy includes deep friction massage and myofascial relaxation techniques to masticatory and neck muscles, active and resistant temporomandibular joint movements, temporomandibular joint distraction and mobilization, stretching techniques to the temporomandibular joint, mobilization of upper cervical joints. Home Exercise program includes educational training program about parafunctional activities of patients having oral dysphagia with temporomandibular disorders. Program includes stretching and strengthening of masticatory and neck muscles and posture exercises as well as diaphragmatic breathing exercises. |
Procedure: Manual Therapy Combined with Home Exercise
Manual therapy program combined with educational training program about oral dysphagia in patients with temporomandibular disorders.
|
| Active Comparator: Orofacial Myofunctional Therapy combined with Manual Therapy and Home Exercise Orofacial Myofunctional therapy includes stretching the tongue muscles, tongue rotation exercises, isometric and isotonic strengthening of the tongue, special maneuver, effortful swallow exercise, strengthening exercise of hyoidal muscles. Manual Therapy includes deep friction massage and myofascial relaxation techniques to masticatory and neck muscles, active and resistant temporomandibular joint movements, temporomandibular joint distraction and mobilization, stretching techniques to the temporomandibular joint, mobilization of upper cervical joints. Home Exercise program includes educational training program about parafunctional activities of patients having oral dysphagia with temporomandibular disorders. Program includes stretching and strengthening of masticatory and neck muscles and posture exercises as well as diaphragmatic breathing exercises. |
Procedure: Orofacial Myofunctional Therapy combined with Manual Therapy and Home Exercise
Orofacial Myofunctional Therapy program with combination of Manual therapy and educational training program about oral dysphagia in patients with temporomandibular disorders.

Outcome Measures
Primary Outcome Measures
- Change from Baseline in Pain at 10 weeks and 6 months [Baseline, 10 weeks, 6 months]
Visual Analog Scale will be used where patients will be asked to rate their pain on a scale from 0 to 10 with 0 indicating no pain and 10 the maximum worst pain, at the baseline and the end of 10 weeks intervention and at the end 6 months from baseline.
- Change from Baseline in Tongue strength and endurance at 10 weeks and 6 months [Baseline, 10 weeks, 6 months]
Tongue strength will be assessed by Iowa Oral Performance Instrument with the measurement of muscle strength by tongue muscle pressure. Tongue endurance will be measured with the Iowa Oral Performance Instrument by quantifying the length of time that a patient may maintain 50% of his or her maximum pressure.
- Change from Baseline in Jaw Function limitation at 10 weeks and 6 months [Baseline, 10 weeks, 6 months]
Jaw function limitation will be measured by the Jaw Functional Limitation Scale-20 (JFLS-20) where the patients will be asked from 1 to 10 points per item (higher scores indicate worse jaw function). The JFLS-20 has 3 subscales: Mastication (6 items), Vertical Jaw Mobility (4 items), and Emotional and Verbal Expression (10 items).
- Change from Baseline in Swallowing dysfunction at 10 weeks and 6 months [Baseline, 10 weeks, 6 months]
The first evaluation for swallowing dysfunction will be assessed with 100 ml water swallow test (WST). For the WST, we will be ask participants to consume 100ml of water in the shortest amount of time. Patients will be assessed to have failed the WST according to published criteria of, (1) coughing or choking post swallow, (2) having a wet voice quality post swallow, or (3) being unable to drink the whole amount of water. Furthermore, the swallowing speed will be evaluated as the amount of consumed water divided by the elapsed time. The second evaluation for swallowing dysfunction will be assessed with Eating Assessment Tool-10 (EAT-10) questionnaire. The EAT-10 is a self-administered, symptom-specific outcome assessment for swallowing dysfunction, demonstrating good consistency, reproducibility, and validity. It consists of 10 questions answered in a scale of 0 to 4 (0: no problem to 4: severe problem), with the higher scores indicating severe dysphagic symptoms.
- Change from Baseline in Quality of life at 10 weeks and 6 months [Baseline, 10 weeks, 6 months]
The quality of life will be evaluated with Swallowing-related Quality of Life questionnaire (Swal-QoL). The SWAL-QoL is a dysphagia specific quality of life instrument consisting of 44 items (11 scales) assessing ten QOL domains: food selection, burden, mental health, social functioning, fear, eating duration, eating desire, communication, sleep, and fatigue. Sleep and fatigue contribute to general QOL, whereas the other domains are contributors to dysphagia-specific QOL. The total SWAL-QOL score includes 23 items from seven domains.
