✍️ Sample EDT Questions & Answers
1. Which nerve conduction parameter is most affected by limb temperature, increasing as temperature decreases?
Cooling slows sodium channel kinetics, prolonging distal latency and increasing duration of nerve conduction potentials; amplitude may also increase due to reduced temporal dispersion.
2. What analysis time (sweep duration) is typically used for upper extremity median nerve SSEP recordings?
A sweep of 50–60 ms is standard for upper extremity SSEPs because it captures all relevant components from the Erb's point potential through the cortical N20/P23, with an adequate pre-stimulus baseline.
3. Which part of the brain is responsible for coordinating movement and balance?
The cerebellum, located at the back of the brain, is primarily responsible for coordinating voluntary movements, maintaining posture, balance, and motor learning. It integrates sensory input from the spinal cord with motor commands from the cerebral cortex to fine-tune movements.
4. EDX evaluation of a meralgia paresthetica (lateral femoral cutaneous nerve entrapment) relies primarily on:
The lateral femoral cutaneous nerve is a pure sensory nerve; LFCN sensory NCS comparing sides (amplitude and latency) is the primary EDX test for meralgia paresthetica.
5. Which spinal cord tract carries proprioceptive information ipsilaterally to the cerebellum?
The dorsal spinocerebellar tract conveys unconscious proprioceptive signals from the lower limb ipsilaterally to the cerebellum.
6. In a patient with peroneal nerve palsy at the fibular head, needle EMG of which muscle would help differentiate it from L5 radiculopathy?
The short head of the biceps femoris is innervated by the peroneal division of the sciatic nerve above the fibular head; denervation there indicates a more proximal sciatic or L5 lesion, not isolated fibular head palsy.
