About

Determining the effects of an intervention plan on the diaphragm related to the center of gravity and range of motion in the lumbar spine (static and dynamic) in healthy individuals is an area that lacks evidence and proper studies. Has such, the investigators consider this a interesting topic to study, therefore it is intended to improve the knowledge on this area.

Full description

All diaphragmatic activity is controlled by metabolic mechanisms and emotional states which may cause restrictions that might be related to disorders in the lower back.

The diaphragm and the lumbar segment of the spine are connected through the diaphgramathic pillars that connect the central tendon and the vertebrae of L2 (left side) and L3/L4 (right side). Consequently, the contraction of the pillars may be related to the fixation of the lumbar spine.

Proper function of the diaphragm is related to better parameters of static balance. It is also possible to conclude that a change in the proper function of the diaphragm is associated with changes in the center of gravity in healthy individuals.

This theme lacks scientific evidence, since no studies were found that focus on the analysis of diaphragmatic treatment only. In this way, the investigators intend to collaborate to increase knowledge in this area, determining the effects of the intervention plan on the diaphragm in relation to the range of motion and center of gravity in the lumbar spine (static and dynamic) in healthy individuals.

60 participants in 2 patient groups

Intervention Protocol in Diaphragm

Experimental group

Description:

In each volunteer, after a brief questionnaire, it will be measured the center of gravity and the range of movement of the lumbar spine before the technique. Each volunteer will stay in supine position with arms along their body, in which their legs may be either extended or flexed. Next, the researcher will perform the intervention protocol in Diaphragm. Then, all the measurements described before, will be repeated by the assessor right after the technique.

Other: Intervention Protocol in Diaphragm

Sham Technique

Sham Comparator group

Description:

In each volunteer, after a brief questionnaire, it will be measured the center of gravity and the range of movement of the lumbar spine before the technique. Each volunteer will stay in supine position with arms along their body, in which their legs may be either extended or flexed. Next, the researcher will perform the Sham technique. Then, all the measurements described before, will be repeated by the assessor right after the technique.
