Thermoregulatory sweat testing in male

Thermoregulatory sweat testing in a 58-year-old man who developed dysesthesia and hypersensitivity of skin to touch with modest pain in his abdomen below the rib cage staring slightly asymmetrical on the right and spread quickly to the left. On examination, he had hyperesthesia in the T6 to T11 dermatomes bilaterally. EMG reveals active and chronic multiple bilateral thoracic radiculopathies, slightly worse on the left, in addition to mild distal chronic, axonal, sensorimotor peripheral polyneuropathy with no active denervation. Thermoregulatory sweat testing shown in the figure showed reduced sweat involving T5 to T11 bilaterally. His symptoms slowly improved over the next year.
