Exam 12: Diagnostic Testing in Neurology: Lab Tests, imaging, and Nervemuscle Studies With Implications for Therapists

Which of the following EMG/NCS findings would be most indicative of muscle reinnervation at 10 months post-trauma?

Your patient presents with the following NCS and EMG findings: Decreased CMAP but normal SNAP amplitudes,normal motor and sensory nerve conduction velocity (NCV) values,repetitive motor nerve stimulation (RMNS) shows decreased response post exercise,no insertional activity,few spontaneous fibrillations,and some decreased amplitude polyphasic waveforms.This is suggestive of which of the following myopathic conditions?

Which of the following diagnostic imaging techniques reflects the current metabolic rate of the tissue?

When looking at EMG interference patterns,a "picket fence" appearance suggests a neuropathic lesion.The "space between the pickets" helps determine whether the neuropathy is due to an upper motor neuron lesion (UMNL) or a lower motor neuron lesion (LMNL),because:

Your patient presents with the following nerve conduction study (NCS) and electromyography (EMG) findings: Decreased CMAP and SNAP amplitudes,motor,and sensory NCV values greater than 75%,no insertional activity,no spontaneous EMG activity but polyphasic waveforms.This is suggestive of which of the following neuropathic conditions?

Which of the following has been shown to be superior in identifying acute brain infarction,within 12 hours of onset?

Abnormal sensory nerve studies would most likely be seen with:

The most useful assessment of peripheral nerve axonal loss is…

Due to the clinical overlap between different types of muscular dystrophy,myopathies,and congenital myasthenic syndromes,a patient under your care was recently given a neuromuscular disorders genetic screening panel to help the physician diagnose their specific condition.Which area of the clinical laboratory would be responsible for handling this analysis?
