Abstract

Synchronous photoelectric measurements of the arm-to-ear and arm-to-foot times were made in two comparable groups: one group of normal individuals (n = 20) and another group of patients with neurocirculatory asthenia (n = 20). The mean arm-to-ear times did not differ significantly, whereas the mean arm-to-foot times (“peripheral circulation times”) demonstrated a marked divergence which proved to be significant on statistical evaluation (p smaller than 0.01). This abnormal slowing of the blood flow should be considered to be characteristic of neurocirculatory asthenia. To what extent the pathophysiologic behavior does explain the symptomatology of that disease must be investigated further.
