There were significant differences between IBD and HC in time domain HRV and significant decreases in high-frequency power measures were also noted, in both IBS and IBD compared with HC. Parasympathetic nervous system activity, represented through high-frequency power, seems to be lower in people with IBS and IBD, but conclusions are limited by the small number of studies that provide usable data, methodological heterogeneity, and high risks of bias in primary study methods and measures.

Cervicogenic headache has been known to originate from the convergence of the upper 3 cervical and trigeminal afferents. The administration of conservative treatments, interventional procedures, and more recently, pulsed radiofrequency, has been used to relieve cervicogenic headache. In this study, the authors evaluated the clinical efficacy and safety of pulsed radiofrequency targeting the mid-cervical medial branches. From September 2012 until December 2017, 395 patients were diagnosed with cervicogenic headache based on the third edition of the International Classification of Headache Disorders. The authors treated them conservatively at first, and those patients with nonresolution of pain were treated with mid-cervical medial branches block applied from C3 to C5 twice. Subsequently, if any patient continued to experience persistent pain, the authors classified them as having intractable cervicogenic headache and performed pulsed radiofrequency treatment targeting the mid-cervical medial branches from C3 to
