Allochiria is the mislocation of sensory stimuli. This study clarifies the historical definitions of allochiria and allesthesia, advocating for a return to original meanings to resolve current medical confusion.

Area of Science:

  • Neurology
  • Neuroscience
  • Medical History

Background:

  • Allochiria, the misplacement of sensory stimuli to the contralateral body or space, was defined by Obersteiner in 1882.
  • Stewart (1894) described a similar phenomenon, allesthesia, involving displacement on the same extremity.

Observation:

  • Jones (1907) controversially redefined both allochiria and allesthesia, attributing the former to hysteria.
  • This reinterpretation has led to conflicting definitions in contemporary medical literature.

Findings:

  • The historical and etymological evidence does not support Jones' redefinition of allochiria and allesthesia.
  • Current medical dictionaries and textbooks present contradictory understandings of these terms.

Implications:
