CHT Therapeutic Interventions 4

Question 1

A therapist treats a patient with lateral epicondylitis using friction massage. This technique is BEST applied:

Accepted Answer

Transversely across the common extensor origin with the elbow extended

Answer

Transverse friction massage (Cyriax technique) is applied perpendicular to the common extensor tendon fibers at their origin to promote collagen realignment.

Question 2

Which orthosis is indicated to prevent boutonnière deformity after an acute central slip injury at the PIP joint?

Accepted Answer

PIP joint extension splint worn continuously, leaving DIP and MCP free

Answer

Continuous PIP extension splinting for 6 weeks allows the central slip to heal in a lengthened position and prevents boutonnière deformity.

Question 3

A CHT applies fluidotherapy at 48°C for 20 minutes to a patient's hand. The PRIMARY therapeutic effect is:

Accepted Answer

Superficial tissue heating with gentle mechanical stimulation aiding desensitization

Answer

Fluidotherapy provides superficial dry heat and particle agitation, making it especially useful for desensitization and gentle range-of-motion exercises in the warm medium.

Question 4

During fabrication of an anti-spasticity splint for a patient with stroke-related hand spasticity, the thumb should be positioned in:

Accepted Answer

Palmar abduction and extension to prevent adduction contracture

Answer

Palmar abduction and extension of the thumb maintains the first web space and counteracts the spastic adduction pattern common after stroke.

A therapist is using low-level laser therapy (LLLT) for wound healing on a chronic hand ulcer. The appropriate application technique is:

Accepted Answer

Non-contact method above intact skin surrounding the wound
