NPTE-PT Neuromuscular System Interventions 5

Question 1

When applying the PNF technique of approximation at the shoulder, what is the PRIMARY physiological mechanism?

Accepted Answer

Joint compression stimulating mechanoreceptors to facilitate co-contraction and postural stability

Answer

Approximation compresses joint surfaces, stimulating articular mechanoreceptors and muscle spindles, which reflexively facilitates simultaneous contraction of muscles surrounding the joint for stability.

Question 2

A patient recovering from Guillain-Barré syndrome (GBS) is in the recovery phase. Which exercise parameter is MOST critical to monitor?

Accepted Answer

Signs of overwork weakness including increased fatigue and declining function

Answer

Overwork weakness in GBS occurs when denervated or partially reinnervated muscles are exercised beyond their capacity, causing a lasting decline in strength that may not fully recover.

Question 3

Task-oriented gait training for stroke survivors should PRIMARILY emphasize which characteristic to maximize neuroplastic benefit?

Accepted Answer

High repetitions of the complete walking task practiced in variable real-world contexts

Answer

Neuroplasticity is driven by high-dose, task-specific, variable practice of the actual walking task; specificity of training and volume of practice are the primary drivers of cortical reorganization.

Question 4

Which intervention is CONTRAINDICATED for a patient in the acute inflammatory phase of polymyositis?

Accepted Answer

High-intensity progressive resistive exercise

Answer

High-intensity exercise during active myositis inflammation can increase muscle enzyme levels, worsen inflammation, and cause further muscle damage; only gentle ROM is appropriate in the acute phase.

Question 5

When using aquatic therapy for neuromuscular re-education, which property of water is MOST therapeutically beneficial for enabling movement practice that is not possible on land?

Accepted Answer

Buoyancy reducing effective body weight to allow movement with weak muscles

Answer

Buoyancy reduces the load of gravity on the body, allowing patients with significant neuromuscular weakness to practice active movement and gait patterns that they cannot yet perform on land.
