CHT Evaluation 4

Question 1

A patient presents with inability to fully extend the DIP joint with the PIP held in extension. Which evaluation finding most suggests mallet finger?

Accepted Answer

Passive DIP extension is full but active extension is lost

Answer

In mallet finger, the terminal extensor tendon is disrupted, so passive DIP extension is preserved but active DIP extension is lost.

Question 2

When using the total active motion (TAM) formula, which joints are included in the calculation?

Accepted Answer

MCP, PIP, and DIP joints

Answer

TAM sums active flexion at the MCP, PIP, and DIP joints minus any extension deficits at those same joints.

Question 3

A patient with rheumatoid arthritis presents for hand evaluation. What deformity is characterized by PIP hyperextension and DIP flexion?

Accepted Answer

Swan-neck deformity

Answer

Swan-neck deformity is characterized by PIP hyperextension combined with DIP flexion, commonly seen in rheumatoid arthritis.

Question 4

Which standardized dexterity test requires the patient to turn over small cards and sort them into categories, assessing hand speed and coordination?

Accepted Answer

Jebsen-Taylor Hand Function Test

Answer

The Jebsen-Taylor Hand Function Test includes a card-turning subtest among its seven timed tasks assessing functional hand activities.

Question 5

During sensory re-education evaluation, which finding would indicate the patient is in the early phase of sensory recovery?

Accepted Answer

Perception of 30 Hz vibration (tuning fork) but not 256 Hz

Answer

Recovery of 30 Hz vibration perception before 256 Hz indicates early-phase sensory return, as larger fibers recover first.
