CHT Therapeutic Interventions — Questions and Answers

Question 1: Which modality is commonly used to reduce inflammation in acute hand injuries?

Heat therapy
Cold therapy (cryotherapy) (Correct answer)
Ultrasound
Electrical stimulation

Correct answer: Cold therapy (cryotherapy)

Cold therapy, or cryotherapy, is commonly used to reduce inflammation in acute hand injuries. Applying cold causes vasoconstriction, which decreases blood flow to the injured area, thereby reducing swelling, pain, and muscle spasms. It is most effective in the initial stages of injury to manage the inflammatory response.

Question 2: What is the goal of tendon gliding exercises?

Increase strength
Reduce inflammation
Prevent adhesions and promote mobility (Correct answer)
Promote circulation

Correct answer: Prevent adhesions and promote mobility

The primary goal of tendon gliding exercises is to prevent adhesions and promote the smooth, independent mobility of tendons within their sheaths. After injury or surgery, tendons can stick to surrounding tissues, limiting movement. These specific exercises help maintain the differential gliding of tendons, which is crucial for restoring full range of motion and hand function.

Question 3: Which splint is most appropriate for carpal tunnel syndrome?

Dynamic extension splint
Resting hand splint
Neutral wrist splint (Correct answer)
Thumb spica splint

Correct answer: Neutral wrist splint

A neutral wrist splint is most appropriate for carpal tunnel syndrome. This splint positions the wrist in a neutral or slightly extended position, which minimizes pressure on the median nerve as it passes through the carpal tunnel. Maintaining this position, especially at night, helps reduce nerve compression and alleviate symptoms like numbness, tingling, and pain.

Question 4: When is neuromuscular electrical stimulation (NMES) used?

To relieve pain only
To reduce inflammation
To improve muscle re-education and strength (Correct answer)
To immobilize joints

Correct answer: To improve muscle re-education and strength

Neuromuscular electrical stimulation (NMES) is used to improve muscle re-education and strength, particularly after injury or surgery. It delivers electrical impulses to stimulate muscle contractions, which can help patients regain voluntary control over weakened muscles, prevent atrophy, and increase muscle strength. NMES is a valuable tool for facilitating motor recovery.

Question 5: Why is patient education crucial in therapeutic interventions?

It reduces paperwork
It helps with billing
It enhances adherence and outcomes (Correct answer)
It shortens treatment time

Correct answer: It enhances adherence and outcomes

Patient education is crucial in therapeutic interventions because it significantly enhances adherence to treatment plans and ultimately improves outcomes. When patients understand their condition, the purpose of their exercises, and how to manage their symptoms, they are more likely to actively participate in their recovery. This empowerment leads to better self-management and long-term success.

Question 6: What is the purpose of mirror therapy?

To improve blood circulation
To reduce edema
To treat phantom pain and improve function (Correct answer)
To increase ROM

Correct answer: To treat phantom pain and improve function

Mirror therapy creates a visual illusion where the patient sees their intact limb moving in place of the missing or affected limb. This visual feedback helps to 'trick' the brain, reducing the perception of phantom limb pain and facilitating motor control. It addresses the brain's remapping and sensory-motor disorganization often associated with amputation or stroke, thereby improving function.

Question 7: What does 'graded motor imagery' involve?

Only massage therapy
Passive stretching
Imagined and real movement for pain reduction (Correct answer)
Electrical stimulation

Correct answer: Imagined and real movement for pain reduction

Graded motor imagery (GMI) is a rehabilitation technique that involves a sequence of mental and physical exercises designed to retrain the brain's motor cortex. It progresses from left/right discrimination, to imagined movements, and finally to mirror therapy, gradually re-engaging the motor system without causing pain. This approach helps to normalize cortical representation and reduce chronic pain by desensitizing the nervous system to movement.

Question 8: Why are occupation-based activities important?

They are time fillers
They relax the patient
They restore functional daily tasks (Correct answer)
They prevent boredom

Correct answer: They restore functional daily tasks

Occupation-based activities are central to hand therapy because they involve purposeful tasks that are meaningful to the patient's daily life. By engaging in activities like dressing, cooking, or writing, patients directly practice and improve the specific movements and skills needed for their functional independence. This approach ensures that therapy outcomes are directly transferable to real-world situations, promoting lasting recovery and participation.

Question 9: What intervention supports scar management?

Hot packs
Isometric exercises
Cold therapy
Use of silicone gel sheeting (Correct answer)

Correct answer: Use of silicone gel sheeting

Silicone gel sheeting is a widely recognized and effective intervention for scar management, particularly for hypertrophic and keloid scars. It works by hydrating the scar tissue, reducing collagen production, and applying gentle pressure, which helps to soften, flatten, and reduce the discoloration of the scar. This promotes a more pliable and aesthetically pleasing scar, improving both function and appearance.
