SCS Therapeutic Interventions 3 — Questions and Answers
Question 1: A distance runner with iliotibial band syndrome fails to improve with stretching. Which additional intervention has the strongest evidence for symptom reduction?
- Corticosteroid injection into the IT band itself
- Hip abductor and external rotator strengthening (Correct answer)
- Lumbar stabilization exercises only
- Aggressive foam rolling of the distal IT band over the lateral femoral condyle
Correct answer: Hip abductor and external rotator strengthening
Hip abductor and external rotator weakness contributes to excessive hip adduction, increasing IT band tension; strengthening these muscles reduces symptoms.
Question 2: During instrument-assisted soft tissue mobilization (IASTM), which physiological response is the PRIMARY therapeutic mechanism?
- Permanent elongation of scar tissue fibers
- Local inflammatory response triggering fibroblast proliferation and collagen remodeling (Correct answer)
- Electrical stimulation of nerve endings
- Immediate reduction of intramuscular pressure
Correct answer: Local inflammatory response triggering fibroblast proliferation and collagen remodeling
IASTM creates a controlled microtrauma that initiates a local inflammatory cascade, stimulating fibroblasts to remodel dysfunctional collagen.
Question 3: Which taping technique is MOST evidence-supported for acutely reducing pain and improving function in patellofemoral pain syndrome?
- Lateral patellar taping to increase lateral glide
- McConnell medial patellar taping (Correct answer)
- Circumferential knee compression wrap
- Longitudinal patellar tendon taping
Correct answer: McConnell medial patellar taping
McConnell medial patellar taping corrects lateral patellar maltracking, reducing patellofemoral contact stress and pain.
Question 4: A gymnast presents with a stress fracture of the pars interarticularis (spondylolysis). Which therapeutic exercise should be AVOIDED during early rehabilitation?
- Lumbar stabilization in neutral spine
- Hip flexor stretching in supine
- Repeated lumbar hyperextension exercises (Correct answer)
- Core activation with diaphragmatic breathing
Correct answer: Repeated lumbar hyperextension exercises
Repeated lumbar hyperextension places compressive and shear forces on the pars interarticularis, exacerbating the stress fracture.
Question 5: When using cryotherapy with compression for an acute ankle sprain, the recommended application duration is:
- 5 minutes every hour
- 10–20 minutes, repeated every 1–2 hours (Correct answer)
- 45–60 minutes continuously
- Only when pain exceeds 7/10 on VAS
Correct answer: 10–20 minutes, repeated every 1–2 hours
10–20 minutes is sufficient to cool subcutaneous tissue while avoiding frostbite; repeating every 1–2 hours maintains analgesic effects.
Question 6: A swimmer with subacromial impingement syndrome benefits MOST from which postural correction exercise early in rehabilitation?
- Scapular depression and protraction exercises
- Serratus anterior and lower trapezius activation to improve scapular upward rotation (Correct answer)
- Pectoralis minor stretching alone
- Aggressive glenohumeral internal rotation strengthening
Correct answer: Serratus anterior and lower trapezius activation to improve scapular upward rotation
Improving scapular upward rotation through serratus anterior and lower trapezius activation increases subacromial space and reduces impingement.
Question 7: Which blood flow restriction (BFR) training parameter is recommended for promoting hypertrophy and strength in a post-surgical athlete unable to use high loads?
- Cuff pressure at 20–30% limb occlusion pressure, 4–6 sets of 3 reps
- Cuff pressure at 40–80% limb occlusion pressure, 3–4 sets of 15–30 reps at 20–30% 1RM (Correct answer)
- Cuff pressure at 100% limb occlusion pressure, 5 sets of 5 reps
- Continuous arterial and venous occlusion for 20 minutes
Correct answer: Cuff pressure at 40–80% limb occlusion pressure, 3–4 sets of 15–30 reps at 20–30% 1RM
BFR at 40–80% limb occlusion pressure combined with high repetitions at low loads (20–30% 1RM) effectively stimulates hypertrophic adaptations.
