Key result
Blood flow oscillations at ~0.1 Hz in skin microvessels showed no relationship with the intactness of sympathetic innervation, indicating they do not reflect sympathetic regulation of tone.

Questions use of 0.1 Hz skin oscillations as sympathetic markers; leaves open local origins for mechanistic validation.
Observational (n=82)
Blood flow oscillations at ~0.1 Hz in skin microvessels are of local origin and do not reflect sympathetic thermoregulatory innervation.
А. И. Крупаткин (2009) conducted an observational in Syndromes of hand and foot sympathectomy and denervation (n=82). Sympathectomy and denervation vs. Intact sympathetic innervation was evaluated on Relationship between 0.1 Hz vasomotions and intactness of sympathetic innervation. Blood flow oscillations at ~0.1 Hz in skin microvessels showed no relationship with the intactness of sympathetic innervation, indicating they do not reflect sympathetic regulation of tone.
