Summary

Leprosy patients with insensitive feet experience severe loss of pressure sensation. Loss of vibration sense is more pronounced with tarsal disintegration, indicating its role in this destructive process.

Area of Science:

  • Neurology
  • Orthopedics
  • Dermatology

Background:

  • Leprosy can cause loss of sensation in the feet.
  • Tarsal disintegration is a severe complication in anesthetic feet.
  • Deep sensation loss may contribute to tarsal disintegration.

Purpose of the Study:

  • To assess sensory loss in leprosy patients with tarsal disintegration.
  • To investigate the role of vibration and pressure sensation in tarsal disintegration.
  • To evaluate the biosthesiometer as a clinical tool for risk assessment.

Main Methods:

  • Assessed vibration and pressure sensations in 21 leprosy patients.
  • Compared sensory loss between feet with and without tarsal disintegration.
  • Utilized a biosthesiometer for vibration sense measurement.

Main Results:

  • Both groups showed severe pressure sensation impairment.
  • Feet with tarsal disintegration had more severe vibration sense loss.
  • Deep sensory loss is linked to tarsal disintegration in anesthetic feet.

Conclusions:

  • Loss of deep sensation is a key factor in tarsal disintegration.
  • Biosthesiometer measurement of vibration sense is valuable for identifying at-risk patients.
  • Early detection can aid in managing insensitive feet and preventing complications.
