CHT Therapeutic Interventions 5

Question 1

A patient with de Quervain's tenosynovitis is fitted with a thumb spica splint. Which wrist and thumb position is MOST appropriate?

Accepted Answer

Wrist neutral, thumb CMC and MP in palmar abduction and extension

Answer

The thumb spica splint for de Quervain's positions the wrist in neutral and the thumb in palmar abduction/extension to rest the APL and EPB tendons.

Question 2

A CHT performs joint mobilization to the hamate-triquetrum joint for a patient with ulnar-sided wrist pain. The mobilization technique for restricted dorsal glide would include:

Accepted Answer

Stabilizing the hamate and gliding the triquetrum dorsally

Answer

To restore dorsal glide, the distal bone (triquetrum) is mobilized dorsally relative to the stabilized proximal bone (hamate).

Question 3

In the early phase of rehabilitation after extensor tendon repair in zone VI (dorsal hand), the therapist should avoid:

Accepted Answer

Composite wrist flexion with simultaneous MCP flexion

Answer

Simultaneous wrist and MCP flexion creates maximum extensor tendon tension, risking rupture in the early healing phase.

Question 4

When treating a patient with a replanted finger, which modality is CONTRAINDICATED in the early postoperative period?

Accepted Answer

Cold (cryotherapy) application over the replanted digit

Answer

Cold application is contraindicated after replantation because vasoconstriction threatens the already tenuous vascular supply to the replanted digit.

Question 5

A patient recovering from a radial nerve injury (posterior interosseous nerve) demonstrates wrist drop. The appropriate splint to provide function is:

Accepted Answer

Dynamic wrist and finger extension splint (outrigger with rubber band assist)

Answer

A dynamic extension splint with outrigger and rubber band assist replaces lost wrist and finger extension from radial/PIN nerve injury, enabling functional grasp and release.
