Chronic hemodialysis patients often experience sensory nervous system abnormalities. Neuroselective transcutaneous electrical nerve stimulation (TENS) revealed significant peripheral (PNS) and central (CNS) nervous system dysfunction in these individuals.

Area of Science:

  • Neurology
  • Nephrology
  • Biomedical Engineering

Background:

  • Chronic hemodialysis can affect nervous system function.
  • Assessing peripheral (PNS) and central (CNS) sensory integrity is crucial for patient management.

Purpose of the Study:

  • To quantitatively assess PNS and CNS sensory function in chronic hemodialysis patients.
  • To evaluate the utility of neuroselective transcutaneous electrical nerve stimulation (TENS) for this assessment.

Main Methods:

  • Utilized neuroselective transcutaneous electrical nerve stimulation (TENS) in 19 chronic hemodialysis patients.
  • Assessed PNS integrity using cutaneous current perception threshold (CPT).
  • Developed and employed cranial TENS to assess CNS sensory function via cephalic evoked noncutaneous sensations (CENS).

Main Results:

  • Significant abnormalities were found in both CPT (32%) and CENS (89%) compared to healthy subjects.
  • No correlation was observed between age, dialysis duration, and the presence of PNS or CNS abnormalities.

Conclusions:

  • CPT is a sensitive and practical test for evaluating PNS sensory function in hemodialysis patients.
  • CENS assessment may also be valuable for monitoring CNS sensory function in this population.
