Postural and autonomic modifications following osteopathic manipulative treatment (OMT): comparison between two techniques. A pilot study

Objective: With reference to OMT principles consistent mention is made of the capability of stimulating Autonomic Responses through both Ortho- and Para-Sympathetic channels. Several studies have been performed to demonstrate this kind of interaction. The purpose of this pilot study was twofold: 1) Compare different OMTs that supposedly interact either with Ortho- or Para- Sympathetic branches of the Autonomic System; 2) Ascertain whether there is a relationship between Autonomic Balance and Quiet Upright Stance Balance. Results: A Sample of 51 young healthy students underwent to a series of four assessment tests for both functions over a 5 hr period. Conclusion: The time plot of the main parameters afforded by the Heart Rate Variability (HRV) Instrumental Assessment and by the Romberg Test performed on a Force Platform actually confirmed that different OMTs challenge different Autonomic components and can achieve different responses in quiet upright stance balance control.
