Why the study?
Building on findings that chronic pain patients with impaired DNIS functioning show lower resting HRV, the authors sought to evaluate the impact of SCS on HRV in patients with FBSS.
Does Spinal Cord Stimulation improve heart rate variability in patients with Failed Back Surgery Syndrome?
Does Spinal Cord Stimulation improve heart rate variability in patients with Failed Back Surgery Syndrome?
Spinal cord stimulation in patients with Failed Back Surgery Syndrome appears to increase parasympathetic tone and decrease sympathetic tone, improving autonomic balance as measured by heart rate variability.
No takes yet. Share an insight, caveat, or question.
SCS may improve autonomic balance in FBSS; hypothesis-generating and should not change practice without randomized trials.
Goudman et al. (2019) studied this question.
