Insights

Somatosensory evoked potentials reveal sensory impairments in children with cerebral palsy. Abnormalities correlate with electroencephalogram, visual evoked potentials, and perinatal infections.

Area of Science:

  • Neurology
  • Neurophysiology
  • Developmental Pediatrics

Background:

  • Bilateral spastic cerebral palsy (CP) affects motor function, but sensory pathway involvement is less understood.
  • Evoked potentials are valuable tools for assessing sensory pathway integrity in pediatric neurological disorders.

Purpose of the Study:

  • To investigate alterations in somatosensory evoked potentials (SEPs) in children with bilateral spastic CP.
  • To correlate SEP findings with clinical and laboratory parameters, including electroencephalogram (EEG) and visual evoked potentials (VEPs).

Main Methods:

  • Fifty-one children (24-168 months) with bilateral spastic CP underwent SEP testing for median and tibial nerves.
  • Data were correlated with EEG, VEPs, and history of perinatal/neonatal infections.

Main Results:

  • Abnormalities were frequent in cortical SEPs: 67.6% for median nerve and 74.5% for tibial nerve.
  • Abnormal tibial nerve SEPs correlated with abnormal EEG (P=0.014).
  • Abnormal median nerve SEPs correlated with abnormal VEPs (P=0.02) and perinatal/neonatal infection history (P=0.016).

Conclusions:

  • Sensory impairments are common in bilateral spastic CP, as indicated by abnormal SEPs.
  • SEP abnormalities are linked to EEG and VEP alterations.
  • Perinatal/neonatal infections negatively impact sensory pathway function in CP, particularly in quadriplegic patients.
