CHT Evaluation 2 — Questions and Answers
Question 1: Which instrument is the gold standard for measuring grip strength in hand therapy evaluations?
- Pinch gauge
- Dynamometer (Jamar) (Correct answer)
- Goniometer
- Volumeter
Correct answer: Dynamometer (Jamar)
The Jamar hydraulic dynamometer is the gold standard for measuring grip strength and provides reliable, reproducible results.
Question 2: When evaluating two-point discrimination in the hand, what is considered a normal value for the fingertip?
- 1–2 mm
- 6–10 mm
- 2–5 mm (Correct answer)
- 11–15 mm
Correct answer: 2–5 mm
Normal static two-point discrimination at the fingertip is 2–5 mm, reflecting high tactile acuity in this region.
Question 3: A therapist performs the Semmes-Weinstein monofilament test. What does a 2.83 monofilament indicate?
- Loss of protective sensation
- Normal light touch (Correct answer)
- Deep pressure only
- Diminished light touch
Correct answer: Normal light touch
The 2.83 (0.07 g) monofilament corresponds to normal light touch sensation in the hand.
Question 4: During edema assessment, which method is most reliable for measuring hand and finger volumetric change over time?
- Circumferential tape measurement
- Visual inspection
- Water displacement volumetry (Correct answer)
- Skin fold calipers
Correct answer: Water displacement volumetry
Water displacement volumetry is the most reliable and sensitive method for tracking changes in hand and finger edema.
Question 5: What does the Kapandji opposition score assess?
- Grip strength
- Thumb opposition range of motion (Correct answer)
- Pinch force
- Sensory threshold
Correct answer: Thumb opposition range of motion
The Kapandji score (0–10) quantifies thumb opposition by rating the ability of the thumb tip to reach successive finger landmarks.
Question 6: A patient with median nerve injury is evaluated. Which test best assesses intrinsic muscle innervation loss?
- Froment's sign
- Card test (Correct answer)
- Semmes-Weinstein monofilament
- Moving two-point discrimination
Correct answer: Card test
The card test assesses the ability to pinch a card between extended fingers, detecting intrinsic muscle weakness from median or ulnar nerve dysfunction.
Question 7: When documenting active range of motion with a goniometer at the PIP joint, where is the axis of the goniometer placed?
- Over the MCP joint
- Over the lateral aspect of the PIP joint (Correct answer)
- At the base of the distal phalanx
- Over the DIP joint
Correct answer: Over the lateral aspect of the PIP joint
The goniometer axis is placed over the lateral aspect of the PIP joint, aligning the arms with the proximal and middle phalanges.
