Abstract:
By raising the body temperature of 0.5 degrees C the critical fusion frequency of a flickering light increases in normal subjects but decreases in multiple sclerosis (MS) patients. The change was present in 14 patients with definite MS and in 5 of 10 patients with probable MS. No clinical worsening was observed during the procedure or in the following hours.
