PRC Treatment Planning & Manual Techniques 2 — Questions and Answers
Question 1: In PRI treatment planning, which position is used to facilitate left AIC pattern correction during supine exercises?
- Left hip abduction with right hip adduction (Correct answer)
- Bilateral hip flexion with knees together
- Right hip abduction with left knee extended
- Bilateral hip extension with foot flat
Correct answer: Left hip abduction with right hip adduction
Left hip abduction combined with right hip adduction helps unwind the left AIC pattern by repositioning the pelvis and activating left glute medius.
Question 2: Which manual technique in PRI is used to restore left thoracic rotation by addressing the right posterior mediastinum?
- Left lateral trunk shift with manual rib springing
- Right arm reach with manual posterior rib depression on right side (Correct answer)
- Bilateral chest expansion with manual sternum pressure
- Left arm overhead reach with right scapular mobilization
Correct answer: Right arm reach with manual posterior rib depression on right side
Right arm reach combined with manual posterior rib depression on the right facilitates left thoracic rotation by decompressing the right posterior mediastinum.
Question 3: When treating a patient with a right BC pattern, which muscles are typically over-facilitated and need to be inhibited?
- Left serratus anterior and left intercostals
- Right pectoralis minor and right external oblique
- Right sternocleidomastoid and right scalenes (Correct answer)
- Left iliopsoas and left adductors
Correct answer: Right sternocleidomastoid and right scalenes
In the right BC pattern, the right cervical muscles including SCM and scalenes are over-facilitated due to cranial rotation left and right rib flare.
Question 4: During PRI manual treatment, what is the purpose of applying posterior-inferior pressure to the right innominate?
- To facilitate right hip external rotation
- To promote anterior pelvic tilt on the right
- To reposition the right innominate from a forward-rotated position (Correct answer)
- To compress the right sacroiliac joint
Correct answer: To reposition the right innominate from a forward-rotated position
Posterior-inferior manual pressure on the right innominate helps reposition it from the anteriorly rotated position typical in the left AIC pattern.
Question 5: Which breathing technique is integral to PRI manual interventions to facilitate rib repositioning?
- Paradoxical breathing with chest expansion
- Diaphragmatic breathing with full exhalation to allow rib depression (Correct answer)
- Segmental breathing with lateral rib expansion only
- Pursed-lip breathing with breath holding at end-inspiration
Correct answer: Diaphragmatic breathing with full exhalation to allow rib depression
Full exhalation during diaphragmatic breathing allows the dome of the diaphragm to ascend, facilitating rib depression and repositioning elevated ribs.
Question 6: In PRI, which muscle is targeted when using a 90-90 hip lift exercise to inhibit the right posterior capsule?
- Right piriformis (Correct answer)
- Left adductor magnus
- Right iliopsoas
- Left hamstring
Correct answer: Right piriformis
The 90-90 hip lift position targets inhibition of the right piriformis, which becomes over-facilitated in the right posterior capsule pattern.
Question 7: When a PRI clinician applies manual pressure to the left ASIS during a left hip adduction exercise, what is the primary goal?
- Increase left hip flexion range
- Provide tactile cue to facilitate left ilium posterior rotation (Correct answer)
- Reduce left sacroiliac joint compression
- Inhibit left tensor fascia latae
Correct answer: Provide tactile cue to facilitate left ilium posterior rotation
Manual pressure on the left ASIS during hip adduction provides a tactile cue to facilitate posterior rotation of the left ilium, correcting the AIC pattern.
