Rehabilitation and Therapy Orthopedic Rehabilitation 2 — Questions and Answers
Question 1: What is the classic rehabilitation precaution following posterior total hip replacement (THR) to prevent dislocation?
- Avoid hip flexion > 90°, adduction, and internal rotation (Correct answer)
- Avoid hip extension and external rotation
- No weight bearing for 12 weeks
- Avoid all hip strengthening exercises
Correct answer: Avoid hip flexion > 90°, adduction, and internal rotation
Posterior approach THR precautions (hip flex < 90°, no adduction past midline, no internal rotation) protect the posterior capsule repair until adequate healing occurs.
Question 2: Which term describes the wearing away of articular cartilage in a joint, leading to bone-on-bone contact and pain?
- Osteoarthritis (OA) (Correct answer)
- Rheumatoid arthritis (RA)
- Gout
- Avascular necrosis
Correct answer: Osteoarthritis (OA)
Osteoarthritis is a degenerative joint disease characterized by progressive cartilage degradation, subchondral bone changes, osteophyte formation, and joint space narrowing.
Question 3: What is the primary purpose of iontophoresis in orthopedic physical therapy?
- Deliver medication transdermally using electrical current to reduce local inflammation (Correct answer)
- Stimulate muscle contractions for strengthening
- Measure nerve conduction velocity
- Promote bone healing through electrical stimulation
Correct answer: Deliver medication transdermally using electrical current to reduce local inflammation
Iontophoresis uses direct electrical current to drive ionized medication (typically dexamethasone or lidocaine) through the skin to treat local inflammatory conditions.
Question 4: Which orthopedic special test is positive when the patient experiences lateral knee pain during compression and rotation, indicating a meniscal tear?
- McMurray test (Correct answer)
- Lachman test
- Pivot shift test
- Anterior drawer test
Correct answer: McMurray test
The McMurray test produces a click or pain in the medial or lateral joint line when the knee is passively flexed, rotated, and extended, indicating meniscal pathology.
Question 5: What is the SLAP lesion in shoulder pathology?
- Superior Labrum Anterior to Posterior tear of the glenoid labrum (Correct answer)
- Subscapularis and Long head of biceps Anterior Posterior rupture
- Supraspinatus Ligamentous Anterior Posterior injury
- Shoulder Lateral Anterior Posterior displacement
Correct answer: Superior Labrum Anterior to Posterior tear of the glenoid labrum
A SLAP tear involves the superior portion of the glenoid labrum at the biceps anchor attachment, common in overhead athletes and those with traction injuries.
Question 6: Which clinical test is used to identify de Quervain's tenosynovitis affecting the first dorsal compartment of the wrist?
- Finkelstein test (Correct answer)
- Phalen's test
- Tinel's sign
- Allen's test
Correct answer: Finkelstein test
The Finkelstein test reproduces pain over the radial styloid by having the patient tuck the thumb into a fist and perform ulnar deviation, stressing the first dorsal compartment tendons.
