Key result
In four patients with sympathotonic orthostatic hypotension, mild abnormalities in plantar autonomic surface potentials were observed, suggesting a neuropathy affecting low thoracic or lumbar sympathetic neurons.

Hypothesis-generating in rare orthostatic hypotension; larger studies needed before diagnostic adoption.
Case Report (n=4)
Mild abnormalities in plantar autonomic surface potentials in patients with sympathotonic orthostatic hypotension may indicate a neuropathy affecting low thoracic or lumbar sympathetic neurons.
Hoeldtke et al. (1989) conducted a case report in Sympathotonic orthostatic hypotension (n=4). Viral infection or rapid weight loss was evaluated on Autonomic function tests including vasomotor reflexes, norepinephrine production, and autonomic surface potentials. In four patients with sympathotonic orthostatic hypotension, mild abnormalities in plantar autonomic surface potentials were observed, suggesting a neuropathy affecting low thoracic or lumbar sympathetic neurons.
