The loss of the spinothalamic tract leads to pain and temperature sensation being lost from the contralateral side beginning one or two segments below the lesion. In addition, if the lesion occurs above T1 of the spinal cord it will produce ipsilateral Horner's syndrome with involvement of the oculosympathetic pathway.
Dissociated sensory loss is a pattern of neurological damage caused by a lesion to a single tract in the spinal cord which involves preservation of fine touch and proprioception with selective loss of pain and temperature. Understanding the mechanisms behind these selective lesions requires a brief discussion of the anatomy involved.
It is characterized by a corresponding loss of motor function, loss of pain and temperature sensation, and hypotension. Anterior spinal artery syndrome is the most common form of spinal cord infarction. [ 1 ]
Central cord syndrome, almost always resulting from damage to the cervical spinal cord, is characterized by weakness in the arms with relative sparing of the legs, and spared sensation in regions served by the sacral segments. [25] There is loss of sensation of pain, temperature, light touch, and pressure below the level of injury. [26]

The following table describes the IENFD values in males and females of a 3 mm biopsy 10 cm above the lateral malleolus (above ankle outer side of leg). [21] Any value measured below the 0.05 Quantile IENFD values per age span, is considered a reliable positive diagnosis for small fiber peripheral neuropathy.
