Federal University of Health Science of Porto Alegre

Status: Completed

Conditions: Other Disorders of the Autonomic Nervous System; Vertebra; Degeneration

Study type: Interventional

Funder types: Other

Identifiers

UFCSPA-FXA-01

Details and patient eligibility

About

The purpose of this study is to determine whether passive accessory intervertebral mobilization applied to the fourth thoracic vertebra produces autonomic effects.

Full 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.

Enrollment: 86 patients

Sex: All

Ages: 18 to 40 years old

Volunteers: Accepts Healthy Volunteers

---

86 participants in 3 patient groups, including a placebo group

Spinal mobilization

Experimental group

Description:

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.

Treatment:

Other: Spinal mobilization

Spinal Mobilization II

Active Comparator group

Description:

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.

Treatment:

Other: Spinal Mobilization II

Placebo

Placebo Comparator group

Description:

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.

Treatment:

Other: Placebo
