Question 1

Which splint is MOST appropriate for a patient diagnosed with de Quervain's tenosynovitis?

Accepted Answer

Thumb spica splint immobilizing the CMC and MCP joints of the thumb

Answer

A thumb spica splint immobilizes the first CMC and MCP joints to rest the abductor pollicis longus and extensor pollicis brevis tendons that are inflamed in de Quervain's tenosynovitis.

Question 2

In trigger finger (stenosing tenosynovitis), which structure is primarily involved?

Accepted Answer

Flexor digitorum superficialis or profundus tendon catching at the A1 pulley

Answer

Trigger finger occurs when the flexor digitorum superficialis or profundus tendon catches on the thickened A1 annular pulley, causing locking or triggering during active flexion.

Question 3

In sensory re-education following peripheral nerve injury, what is the RECOMMENDED sequence?

Accepted Answer

Begin with protective sensation, then progress to discriminative sensation

Answer

Sensory re-education follows a hierarchical sequence: first restoring protective sensation (pain, temperature, moving touch) before progressing to discriminative sensation (static two-point discrimination).

Question 4

Which approach is MOST appropriate for treating complex regional pain syndrome (CRPS) in occupational therapy?

Accepted Answer

Desensitization, stress loading, and graded active movement

Answer

CRPS treatment emphasizes desensitization to normalize sensory processing, stress loading (weight-bearing/carrying) to stimulate normal limb use, and active movement to reduce sympathetic hypersensitivity.

Question 5

What is the normal range of MCP joint flexion measured with a goniometer?

Accepted Answer

85–90°

Answer

Normal MCP joint flexion ranges from approximately 85–90°, with full fist formation requiring adequate ROM at the MCP, PIP, and DIP joints together.
