PRC PRC Exercise Prescription & Home Program Design 2 — Questions and Answers
Question 1: Which breathing pattern should be emphasized during PRI positional exercises?
- Chest breathing with maximal forced inhalation to expand the rib cage
- Diaphragmatic breathing with controlled exhalation to facilitate rib cage depression (Correct answer)
- Breath holding throughout the exercise to maximize intra-abdominal pressure
- Rapid shallow breathing to activate deep core stabilizers reflexively
Correct answer: Diaphragmatic breathing with controlled exhalation to facilitate rib cage depression
PRI exercises emphasize diaphragmatic breathing with controlled exhalation to facilitate rib cage depression, improve the zone of apposition, and support proper diaphragm positioning.
Question 2: In PRI home programming, 'integrative' exercises are typically introduced:
- At the start of every session as a warm-up before repositioning exercises
- After the patient has demonstrated consistent ability to achieve the repositioned state (Correct answer)
- Only within a clinical setting under direct supervision
- As a complete substitute for manual therapy techniques
Correct answer: After the patient has demonstrated consistent ability to achieve the repositioned state
Integrative exercises in PRI are introduced after repositioning is achieved, allowing the patient to practice maintaining the neutral pattern in progressively more dynamic activities.
Question 3: When instructing a patient in the 90/90 hip lift exercise, the most important primary cue is to:
- Lift hips as high as possible for maximum posterior chain activation
- Squeeze the glutes maximally to push the floor away from the body
- Find left hamstring activation while exhaling and maintaining lumbar contact with the floor (Correct answer)
- Hold the breath to stabilize the spine throughout the lift
Correct answer: Find left hamstring activation while exhaling and maintaining lumbar contact with the floor
The 90/90 hip lift targets left hamstring activation with controlled exhalation and lumbar contact to reposition the left innominate out of anterior rotation.
Question 4: For a patient with a Right BC pattern, which shoulder position would be targeted in PRI home exercises?
- Right shoulder elevation and retraction to restore scapular stability
- Left shoulder protraction and elevation to balance bilateral tension
- Right shoulder protraction, depression, and upward rotation to inhibit pectoralis minor (Correct answer)
- Bilateral shoulder external rotation to restore posterior chain balance
Correct answer: Right shoulder protraction, depression, and upward rotation to inhibit pectoralis minor
Right BC exercises target right shoulder protraction, depression, and upward rotation to inhibit the right pectoralis minor and restore right thoracic rotation capacity.
Question 5: PRI home exercises designed to address the TMCC pattern commonly include:
- Heavy cervical strengthening with resistance bands
- Jaw position and tongue placement awareness combined with cervical repositioning (Correct answer)
- High-load overhead pressing to engage the cervical stabilizers
- Cervical traction and passive joint mobilization techniques
Correct answer: Jaw position and tongue placement awareness combined with cervical repositioning
TMCC home exercises incorporate jaw position and tongue placement awareness combined with cervical repositioning to address the functional craniofacial-cervical chain relationship.
Question 6: How frequently should PRI home exercises typically be performed during the initial phase of treatment?
- Once per week to prevent neuromuscular fatigue and overtraining
- Five to seven times per day continuously throughout waking hours
- One to two times daily with adequate rest between sessions (Correct answer)
- Only during symptomatic flare-up periods as needed for pain relief
Correct answer: One to two times daily with adequate rest between sessions
PRI exercises are typically prescribed 1–2 times daily with appropriate rest to support neuromotor learning without fatigue interfering with proprioceptive sensing.
