简要总结
The purpose of this study is to determine whether passive accessory intervertebral mobilization applied to the fourth thoracic vertebra produces autonomic effects.
详细描述
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.

研究组 & 干预措施
Spinal mobilization
20 subjects will be randomized to this arm. A postero-anterior (PA) mobilization, to the fourth thoracic vertebra will be applied, for 3 sets of one minute. The subject will be comfortable prone lying.
干预措施: Spinal mobilization (Other)
Spinal Mobilization II
20 subjects will be randomized to this arm. A postero-anterior (PA) mobilization, to the fourth thoracic vertebra will be applied, for 3 sets of one minute, but in this case, the subject will be seated, in a position that influence the sympathetic trunk, at the thorax.
干预措施: Spinal Mobilization II (Other)
Placebo
20 subjects will be randomized to this arm. Only manual contact will be applied, without any oscillation. The subject will be comfortable prone lying. The intervention time is the same of the other arms.
干预措施: Placebo (Other)
结局指标
主要结局
Skin conductance
时间窗: 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.
次要结局
- Pressure pain threshold(Change from Baseline imediately after, and 15 minutes after the intervention)
