Osteopathic Manipulative Treatment Induces Functional Connectivity Changes
Study Details
Study Description
Brief Summary
Osteopathic Manipulative Treatment (OMT) is a whole-body intervention mainly focused on correcting the somatic dysfunctions present in different regions of the body. Osteopathic research to date has mostly been concerned with various clinical conditions such as musculoskeletal disorders and primary headache. The neurophysiological effects underlying clinical improvements are still under debate. Although models explaining the therapeutic effects of OMT include the potential for higher brain mechanism, OMT effects on functional brain connectivity is not fully understood and still lacking in healthy adults. Magnetic resonance imaging (MRI) research includes several different approaches to estimate cortical functions. Several of these approaches have demonstrated functional brain changes associated with OMT. Using Arterial Spin Labeling MRI, recently was demonstrated that the treatment of somatic dysfunctions induces cerebral perfusion changes in asymptomatic young participant. Thus, the aim of this study is to explore the neural correlates associated with OMT effect in terms of cerebral functional connectivity, as derived by complex network analysis of resting state fMRI data recorded in asymptomatic young volunteers with somatic dysfunctions

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Osteopatic Manipulative Treatment (OMT)
|
Other: OMT
OMT techniques were focused on correcting the dysfunctions found during the initial physical examination and included articular and myofascial techniques, balanced ligamentous tension, visceral manipulations and osteopathy in the cranial field
|
| Placebo Comparator: Manual Placebo (MP)
|
Other: MP
MP treatment was performed by the same osteopaths who performed OMT and was carried out in the same hospital setting. P treatment consisted of a passive touch without joint mobilization in a protocolled order. The osteopaths were standing next to the bed, they touched lumbar and dorsal spine of the subjects in prone position for 10 minutes, and then in supine position, they touched for 10 minutes the shoulders, the hips, then the neck, the sternum and the chest were touched for 5 minutes each. Another researcher on the placebo protocol specifically trained the osteopaths.

Outcome Measures
Primary Outcome Measures
- functional Magnetic Resonance Imaging (fMRI) changes [at baseline, immediately after the intervention and after 3 days]
Changes in correlation of brain activity in different regions of brain as assessed by Blood Oxygenation Level Dependent (BOLD) signal. fMRI data are collected using gradient-echo echo-planar imaging at 3T (Philips Achieva) using a (T2*)-weighted imaging sequence sensitive to BOLD (TR = 3 s, TE = 30 ms, matrix = 80 x 80, FOV=224x224, slice thickness = 3 mm, flip angle = 90°, 50 slices, 240 vol).
Secondary Outcome Measures
- De-Blinding questionnaire [immediately after the intervention]
The questionnaire consists of three consecutive questions about subjects' perception of the treatment received. After being questioned on whether according to their perception, they thought they have received OMT or MP treatment, subjects were asked on a 0-10 numeric rating scale (NRS), where 0 represented absolutely uncertainty and 10 represented absolutely certainty, how certain they were regarding group allocation. Finally, they were asked to rate the perceived usefulness of the treatment received, based on a 0-10 NRS, where 0 represented absolutely useless and 10 represented absolutely useful
