OCC OCC Musculoskeletal Assessment & Diagnosis 2 — Questions and Answers
Question 1: When performing a structural exam, the osteopathic physician notes that the right ASIS is more anterior and the right leg appears longer. Which ilial dysfunction is most consistent?
- Right anterior ilial rotation (Correct answer)
- Right posterior ilial rotation
- Right superior ilial shear
- Right inferior ilial shear
Correct answer: Right anterior ilial rotation
An anterior ilial rotation on the right causes the right ASIS to move anteriorly and inferiorly, making the right leg appear longer.
Question 2: In cervical spine assessment, a C5 segment is found to flex, side-bend left, and rotate left. How is this dysfunction named in osteopathic nomenclature?
- C5 FSRL (Flexed, Side-bent Right, Rotated Left)
- C5 FSLL (Flexed, Side-bent Left, Rotated Left) (Correct answer)
- C5 ESRL (Extended, Side-bent Right, Rotated Left)
- C5 ESLL (Extended, Side-bent Left, Rotated Left)
Correct answer: C5 FSLL (Flexed, Side-bent Left, Rotated Left)
In osteopathic nomenclature, the dysfunction is named for the position the segment is stuck in: Flexed, Side-bent Left, Rotated Left = FSLL.
Question 3: Which special test for lumbar spine assesses for a herniated disc by eliciting radicular pain below the knee when raising the leg straight with the patient supine?
- Straight leg raise (SLR) (Correct answer)
- Kemp's test
- Milgram test
- Schober test
Correct answer: Straight leg raise (SLR)
The straight leg raise (Lasègue's test) stretches the sciatic nerve and dura, reproducing radicular pain below the knee if a lumbar disc herniation is present.
Question 4: A patient with OA (osteoarthritis) of the knee has crepitus and restricted flexion bilaterally. What osteopathic structural finding would most directly affect lymphatic drainage of the lower extremities?
- Thoracolumbar junction dysfunction (Correct answer)
- Cervical spine dysfunction
- Rib 1 dysfunction
- Occipitoatlantal restriction
Correct answer: Thoracolumbar junction dysfunction
The thoracolumbar junction (T10–L2) houses sympathetic outflow and lymphatic cisterna chyli drainage, making it a key area for lower extremity lymphatic function.
Question 5: In osteopathic assessment of the occipitoatlantal (OA) joint, normal range of motion is primarily in which plane?
- Flexion-extension (sagittal plane) (Correct answer)
- Rotation (transverse plane)
- Side-bending (frontal plane)
- Compression-distraction
Correct answer: Flexion-extension (sagittal plane)
The OA joint primarily allows flexion and extension (nodding motion) with minimal rotation or side-bending.
Question 6: A counterstrain tender point for the iliopsoas is located at which anatomical landmark?
- Medial surface of the ASIS (Correct answer)
- Posterior superior iliac spine
- Greater trochanter
- Iliotibial band at the knee
Correct answer: Medial surface of the ASIS
The anterior counterstrain tender point for the iliopsoas is located on the medial surface of the ASIS and is treated by hip flexion, abduction, and external rotation.
