“…A possible reason for the reduction of nociceptive phenomena recorded by the patient could be linked to the stimulation of the parasympathetic system, compared to a more active sympathetic system after surgery [ 16 ]. A gentle manual approach is able to stimulate the parasympathetic system; the latter is linked to greater pain control, probably due to the nociceptive relations reaching the nucleus tractus solitarius (NTS) and the management from the latter toward other brain areas (anterior limbic area) [ 15 , 17 ]. Another hypothesis is that of the activation of the central descending pain inhibition pathways [ 17 ].…”

Scientific literature demonstrates how osteopathic manipulative treatments (OMT) are able to improve various somatic functional parameters, change somato-visceral and viscero-somatic reflexes toward a more physiological mechano-metabolic environment and, consequently, bring benefits to patients. These benefits can be long-lasting or short-lived. Multiple reasons can be found to explain the positive responses to OMT, ranging from neurological, vascular, lymphatic, and endocrine explanations. Not only the techniques, but the touch of the clinician prove to be important factors for a favorable adaptation by the patient. Another science capable of explaining the change in cellular status and from which reflections that pave the way for observing the human body in a different light can be extrapolated is quantum physics. The latter is rarely taken into consideration to obtain possible explanations of the physical events that occur between the clinician and the patient. The article tries to put the effects of OMT under the light of a new lens: the nanoscopic.

“… 1 , 19 The autonomic nervous system potentially controls the descending pain modulatory systems. 20 These systems are regulated by several neurons, such as the periaqueductal grey, rostral ventromedial medulla, hypothalamus, and amygdala, which secrete aminergic neurotransmitters to ascending pain pathways and modulate pain perception. 20 , 21 Functional magnetic resonance imaging showed that the periaqueductal grey and rostral ventromedial medulla were activated in CPM measurements.…”

Purpose Conditioned pain modulation (CPM) is a measurement of the descending pain pathways that inhibit or facilitate afferent noxious stimuli. The reliability of CPM in older individuals with or without chronic musculoskeletal pain has not been sufficiently reported. This study aimed to examine the inter-session reliability of CPM in these cohorts and the factors in CPM reliability. Patients and Methods Individuals aged 65 or older were recruited in Narita, Japan. The measurements were performed on separate days 2 weeks apart (sessions 1 and 2). Each participant’s hand was immersed in cold water, and we measured pressure pain threshold (PPT) before and after the immersion. The ratio before and after PPT measurements was presented as CPM index. The autonomic activities (heart rate variability, heart rate, and blood pressure) were simultaneously measured. An absolute reliability of CPM index was analyzed by the adjusted two-way analysis of variance (ANOVA) and the Bland Altman plot, and relative reliability was analyzed by intraclass correlation coefficient (ICC). Spearman’s rho correlation and the adjusted multivariate regression analysis were utilized for examining the CPM reliability factors. Results Thirty-two participants were divided into two groups: chronic pain (n=19) and non-chronic pain (n=13) groups. The mean difference between session 1 and 2 in CPM index showed a systematic error in the chronic pain group at 17.3 (confidence interval, CI: 15.0 to 19.7), but none in the non-chronic pain group at 3.7 (CI: −0.02 to 7.4). The adjusted two-way ANOVA for CPM index did not identify any differences. ICC was not significant at p=−0.247 in the non-chronic and 0.167 in chronic pain. Multivariate regression analysis revealed total power and low/high frequencies as significant factors for CPM index. Conclusion This study identified low inter-session reliability in older adults with chronic musculoskeletal pain and autonomic nervous system activities as factors in CPM reliability.

ObjectiveTo investigate the circadian changes of the autonomic function in patients with zoster‐associated pain (ZAP).MethodsA total of 37 patients with ZAP from April 2022 to October 2022 were enrolled as the observation group, and 37 normal volunteers at the same time were selected as the control group. All participants were required to wear a 24‐h Holter, which was used to compare the heart rate variability (HRV) between the two groups. HRV analysis involved time‐ and frequency‐domain parameters.ResultsThere was no statistically significant difference in general information between two groups. Patients with ZAP had an increased mean heart rate and decreased the standard deviation of normal‐to‐normal (SDNN) R–R interval, the root mean square of the differences (RMSSD) in successive RR interval, low frequency (LF), and high frequency (HF) compared with control groups in all periods (p < .05). The ratio of LF/HF between two groups had no significant difference (p = .245). SDNN had no significant difference between day and night in the control group (p > .05), whereas SDNN of ZAP patients in night period was reduced than that in day period (p < .001). The level of RMSSD during the day was lower than those at night in the control group (p < .05), whereas no significant difference of RMSSD between two periods was observed in patients with ZAP (p > .05).ConclusionThe results of this study indicated that ZAP contributes to the decline of autonomic nervous system (ANS) function, especially parasympathetic components. The patients with ZAP lost parasympathetic advantage and had a worse ANS during the night.
