COM Myofunctional Therapy Techniques 2 — Questions and Answers
Question 1: Which biofeedback tool is most commonly used in orofacial myofunctional therapy to help patients visualize tongue posture?
- Electromyography (EMG) (Correct answer)
- Intraoral camera
- Pressure sensor palatography
- T-Scan occlusal analysis
Correct answer: Electromyography (EMG)
EMG biofeedback provides real-time muscle activity data, helping patients consciously correct tongue and lip posture during therapy.
Question 2: A patient consistently breathes through their mouth despite nasal airway clearance. Which therapeutic sequence is most appropriate?
- Begin lip seal exercises immediately
- Refer back to ENT before initiating therapy
- Assess nasal breathing habit awareness then introduce nasal breathing drills (Correct answer)
- Recommend orthodontic expansion first
Correct answer: Assess nasal breathing habit awareness then introduce nasal breathing drills
Habit awareness must precede motor retraining; nasal breathing drills are introduced once the patient understands the behavior they are changing.
Question 3: What is the primary purpose of using a button-pull exercise in myofunctional therapy?
- Strengthen orbicularis oris muscle tone (Correct answer)
- Improve tongue tip elevation
- Correct forward head posture
- Stimulate palatal sutures for expansion
Correct answer: Strengthen orbicularis oris muscle tone
Button-pull exercises resist lip seal to strengthen the orbicularis oris, improving lip competence against the open-mouth habit.
Question 4: During nasal breathing re-education, which posture cue is MOST important to reinforce alongside nasal breathing?
- Mandibular protrusion
- Cervical spine neutral alignment and closed-mouth resting posture (Correct answer)
- Tongue protrusion to the lower incisors
- Elevated shoulder girdle position
Correct answer: Cervical spine neutral alignment and closed-mouth resting posture
Neutral cervical alignment supports an open nasal airway, and closed-mouth resting posture is integral to establishing habitual nasal breathing.
Question 5: A child with a thumb-sucking habit is being treated. Which behavior modification strategy is considered a first-line approach before introducing an oral appliance?
- Immediate placement of a palatal crib
- Positive reinforcement and habit diary with reward charting (Correct answer)
- Tongue thrust re-education exercises
- Frenectomy referral
Correct answer: Positive reinforcement and habit diary with reward charting
Positive reinforcement and self-monitoring through a habit diary are the recommended first-line behavioral approaches before considering appliance therapy.
Question 6: Which exercise specifically targets intrinsic tongue muscle coordination for improved lingual precision during swallowing?
- Tongue lateralization to the commissures
- Tongue-click repetition drill
- Spot placement with sustained hold at the palate (Correct answer)
- Jaw opening against resistance
Correct answer: Spot placement with sustained hold at the palate
Spot placement with sustained hold trains precise tongue tip contact at the rugae, developing intrinsic muscle coordination essential for correct swallowing.
Question 7: When progressing a patient from isolated tongue exercises to functional integration, which task represents the most advanced level?
- Tongue elevation in front of a mirror
- Sustained tongue-to-palate contact at rest for 30 seconds
- Correct tongue posture maintained during quiet nasal breathing and speaking (Correct answer)
- Tongue lateralization touching each molar
Correct answer: Correct tongue posture maintained during quiet nasal breathing and speaking
Maintaining correct tongue posture during dynamic activities like speaking represents the highest level of functional integration in myofunctional therapy.
