OTR Therapeutic Interventions & Techniques 2 — Questions and Answers
Question 1: Which sensory integration technique involves providing deep pressure input through joint compression to improve proprioceptive awareness?
- Vestibular stimulation
- Joint approximation (Correct answer)
- Tactile desensitization
- Visual tracking
Correct answer: Joint approximation
Joint approximation applies compression through a joint to stimulate proprioceptors, improving body awareness and postural stability.
Question 2: An OTR is using constraint-induced movement therapy (CIMT) with a stroke patient. Which element is essential to this approach?
- Bilateral upper extremity exercises
- Restraint of the less-affected limb (Correct answer)
- Passive range of motion to the affected limb
- Electrical stimulation to the stronger arm
Correct answer: Restraint of the less-affected limb
CIMT requires constraining the less-affected arm to force use of the more-affected limb through massed practice.
Question 3: When applying kinesio taping to facilitate a weakened muscle, how should the tape be applied relative to the muscle?
- From insertion to origin with no tension
- From origin to insertion with 25-50% tension (Correct answer)
- Across the muscle belly with maximum stretch
- Over the antagonist muscle with moderate tension
Correct answer: From origin to insertion with 25-50% tension
Facilitation taping applies tape from origin to insertion with 25-50% tension to activate and support a weak muscle.
Question 4: A child with tactile defensiveness reacts negatively to light touch. Which intervention is most appropriate to begin desensitization?
- Feather stroking of the forearms
- Firm pressure through the Wilbarger Brushing Protocol (Correct answer)
- Intermittent cold application
- Vibration over the fingertips
Correct answer: Firm pressure through the Wilbarger Brushing Protocol
The Wilbarger Deep Pressure and Proprioceptive Technique uses firm brushing to reduce tactile hypersensitivity systematically.
Question 5: In mirror therapy for phantom limb pain following amputation, what is the mechanism of action?
- Electrical stimulation of the residual limb
- Visual feedback tricking the brain into perceiving the missing limb as intact (Correct answer)
- Desensitization of the stump through graded exposure
- Strengthening of the residual musculature
Correct answer: Visual feedback tricking the brain into perceiving the missing limb as intact
Mirror therapy uses a mirror reflection of the intact limb to create the visual illusion of a functioning missing limb, reducing cortical pain mapping.
Question 6: Which approach is MOST consistent with the Model of Human Occupation (MOHO) when addressing a patient's occupational dysfunction?
- Analyzing neuromuscular deficits before setting goals
- Exploring the patient's volition, habituation, and performance capacity (Correct answer)
- Using standardized sensorimotor assessments to guide treatment
- Prioritizing biomechanical factors first
Correct answer: Exploring the patient's volition, habituation, and performance capacity
MOHO centers treatment on volition (motivation), habituation (routines/roles), and performance capacity as drivers of occupational engagement.
Question 7: An OTR is treating a patient with chronic pain using graded activity. What is the primary rationale for this approach?
- To maximize joint range of motion through repetition
- To gradually increase activity tolerance while avoiding fear-avoidance behavior (Correct answer)
- To strengthen muscles weakened by disuse as quickly as possible
- To distract the patient from pain using occupation
Correct answer: To gradually increase activity tolerance while avoiding fear-avoidance behavior
Graded activity systematically increases activity demands to build tolerance and counteract the pain-avoidance cycle that leads to deconditioning.
