Brief summary
The purpose of this study is to determine whether passive accessory intervertebral mobilization applied to the fourth thoracic vertebra produces autonomic effects.
Detailed description
Asymptomatic subjects will be recruited to this study. Pressure pain threshold, heart rate, heart rate variability and skin conductance will be measured before, immediately after and fifteen minutes after the intervention. Subjects will be randomized into three groups: Passive accessory intervertebral mobilization one, passive accessory intervertebral mobilization two and placebo group. The researcher that will do the intervention will be blinded to the outcomes measures, and the researcher that will do the measurements will be blind to the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Skin conductance | Change from Baseline imediately after, and 15 minutes after the intervention | Skin conductance will be measured with Biopac MP150, the electrodes will be attached to the third and fourth fingers bilaterally. This measurement will be made during all the procedure, before, during and until 15 minutes after the intervention. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pressure pain threshold | Change from Baseline imediately after, and 15 minutes after the intervention | Pressure pain threshold will be measured with a digital algometer (Model FDX 10; Wagner Instruments, Greenwich, CT). This measurement will be made on the spinous process of C5 and T4, on the first dorsal interossei, and on the anterior tibial tuberosity bilaterally. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Heart rate variability | Change from Baseline imediately after the intervention | Heart rate variability will be measured with a Polar Advantage Interface (Polar Electro Oy, Kempele, Finland). The belt will be positioned centrally, directly below the xiphisternum. Heart rate data acquisition will me made for 5 minutes at baseline and for 5 minutes immediately after the intervention. |
