These 10 free CHT questions are organized by exam domain, so you can see how each part of the CHT blueprint is tested. Reveal the answer and explanation under each question.
A 47-year-old data entry worker reports six weeks of intermittent night-time numbness in the thumb, index, and middle fingers. There is no thenar atrophy, and static two-point discrimination measures 4 mm at all fingertips. Which assessment is MOST appropriate for detecting early median nerve compression?
Correct answer: B - Semmes-Weinstein monofilament testing, since threshold change precedes density change
During examination of a stiff index finger, a therapist finds that passive PIP flexion is markedly limited when the MP joint is held in extension, but improves substantially when the MP joint is passively flexed. This finding indicates:
Correct answer: D - Intrinsic muscle tightness of the involved digit
A patient completes the DASH at initial evaluation and scores 68. Twelve weeks later, after a successful course of therapy, the patient scores 21. This change indicates that the patient's:
Correct answer: C - Disability has decreased by an amount well exceeding the minimal clinically important difference
A patient presents with weakness of the interossei, a positive Froment's sign, and numbness of the small finger and ulnar half of the ring finger. Sensation over the DORSAL ulnar aspect of the hand is intact. This sensory finding MOST supports compression at which site?
Correct answer: D - Guyon's canal
A therapist performs grip strength testing across all five Jamar handle positions. The resulting values are nearly equal at every position, producing a flat curve rather than the expected bell shape. This pattern MOST suggests:
Correct answer: A - Inconsistent effort, since a true bell curve should peak at handle position two or three
A patient is 10 days status post zone II flexor tendon repair and is progressing well on an early passive motion protocol. Regarding tendon healing at this stage, which is the GREATEST concern?
Correct answer: D - Rupture of the repair during the softening phase
A therapist plans continuous thermal ultrasound over the volar wrist of a 12-year-old with post-traumatic stiffness following a distal radius fracture. Which consideration represents the PRIMARY contraindication?
Correct answer: B - Application over an open epiphyseal plate
Eight weeks after a distal radius fracture, a patient reports constant burning pain disproportionate to the injury, with hypersensitivity to light touch, temperature asymmetry, and dorsal hand edema. Composite digit flexion is markedly limited. Which approach is MOST appropriate?
Correct answer: A - Graded motor imagery and stress loading, with pain-free active motion
A patient presents two days after a puncture wound to the volar index finger. The finger is uniformly swollen, held in slight flexion, and tender along the flexor sheath. Passive extension of the digit produces severe pain. The MOST appropriate action is to:
Correct answer: C - Contact the physician for immediate surgical referral
A patient has a chronic 40-degree PIP flexion contracture following a crush injury eight months ago. The joint demonstrates a hard, abrupt end feel with essentially no give at the end of passive range. Which orthotic approach is MOST appropriate?
Correct answer: A - A static progressive PIP extension orthosis, advanced incrementally as tissue accommodates
