[Electromyografic patterns predictive of motor evolution in neuroschistosomiasis]

Area of Science:

• Neurology
• Infectious Diseases
• Neurophysiology

Context:

• Neuroschistosomiasis with myeloradicular involvement is prevalent in Northeast Brazil.
• The evolution of neurological and electromyographic patterns in these patients remains understudied.
• This study focuses on patients presenting with neuroschistosomiasis and radicular involvement.

Purpose:

• To describe and compare the clinical and electromyographic abnormalities in patients with neuroschistosomiasis and radicular involvement.
• To analyze the initial electromyographic findings in the lower limbs of affected patients.

Summary:

• Electromyography (EMG) of 21 patients with neuroschistosomiasis revealed axonal lumbosacral multirradiculopathy in 95.2%.
• Denervation patterns predominantly affected spinal nerve roots from L2 to S2.
• Motor deficits in the lower limbs showed better prognosis when fewer nerve roots were involved.

Impact:

• Electromyography is a valuable tool for assessing motor prognosis in patients with schistosomiasis-induced myeloradiculitis.
• Findings highlight the utility of EMG in understanding the neurophysiological impact of schistosomiasis on the peripheral nervous system.
