Influence of neural mobilization in the sympathetic slump position on the behavior of the autonomic nervous system

Abstract

Introduction: The neural mobilization technique in the sympathetic slump position (NMSS) was based on the slump test, whose purpose was to directly influence the sympathetic trunk and thus provide greater analgesia by sympathetic activation and treat pain syndromes caused by peripheral sympathetic changes. Therefore, as the autonomic nervous system (ANS) is responsible for extrinsic regulation of the cardiovascular system through sympathetic and parasympathetic action, the aim of this study was to investigate the influence of the NMSS technique on the systolic and diastolic blood pressure and heart rate variability in athlete and non-athlete men. Methods: Twenty-eight subjects performed the procedure that was divided into three phases: rest; intervention and recovery, lasting 4 minutes and 30 seconds each, totaling a 13-minute and 30 seconds collection time. Results: The results showed that the NMSS technique significantly influences the action/activity of the ANS, as there was predominant sympathetic activation during the application of the technique, which was observed by the increase in systolic blood pressure, low frequency (LF), LF/HF ratio and decreased values of high frequency (HF). Conclusion: It may be concluded that the neural mobilization technique on the sympathetic slump (NMSS) significantly influences the ANS action/activity. Among the groups there was no statistically significant difference in heart rate variability. It is worth noting that patients with cardiovascular disorders may be at risk if the NMSS technique is applied, since there was an increase in SBP and sympathetic activation during its application in both groups.

Comparative effects of tensioning and sliding neural mobilization on peripheral and autonomic nervous system function: A randomized controlled trial

“…Although limited in the literature, other potential effects of NM on autonomic nervous system function have been reported. 17 The hypothesized autonomic benefits include increased neural vascularity and decreased skin temperature. Currently, there are no randomized controlled clinical trials investigating the effects of different NM techniques on nerve root function and autonomic nervous system.…”
