Effects of Diaphragm-releasing Techniques on the Lumbar Spine and Diaphragmatic Function in Healthy Women

Study Overview
=================
Brief Summary
-----------------
The aim of this study was to evaluate the immediate effects of diaphragmatic release techniques on posterior chain flexibility and lumbar spine amplitude. Respiratory muscle strength and chest cavity mobility in healthy women.

Detailed Description
-----------------
The aim of this study was to evaluate the immediate effects of diaphragmatic release techniques on posterior chain flexibility and lumbar spine amplitude; Respiratory muscle strength and chest cavity mobility in healthy women. This is an intervention study with a randomized controlled trial design. The randomized study in two groups, the Intervention Group in which two diaphragmatic release techniques were performed and the Control Group where two placebo techniques were applied in 75 participants between 18 and 35 years of age. For intragroup analysis the paired Student t test was used, comparing the outcomes before and after the intervention and for intergroup analysis the independent Student t test.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: The sample was randomly divided by electronic draw in two groups, the intervention group (GI), where two techniques were performed, one for diaphragmatic release and another for relaxation of the diaphragm pillars. In the control group (CG) the same techniques were applied, but in a placebo form.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Diaphragmatic release<br>The stretching of the peripheral fibers of the diaphragm | Procedure: Diaphragm lift<br>* The purpose is to generate the stretch of the peripheral fibers of the diaphragm, being performed with the patient in the supine position and the physiotherapist standing on the patient's head and Pulling the Your costal arch In the cephalic direction, for one minute, twice<br>* Other names: Diaphragmatic release 1;Procedure: Relaxation of the diaphragm pillars<br>* Second technique aims to promote the rhythmic stretching of the double psoas diaphragm pillars, being performed with The patient in the ventral position and the therapist standing at his side placing the ulnar border of his cephalic hand on the last ribs and his caudal hand flattened in front of the popliteal fossa of the popliteal fossa, stretching was done for one minute<br>* Other names: Diaphragmatic release 2;|
| Placebo Comparator: Diaphragmatic release control<br>In both placebo techniques, only the light touching of the contacts of the volunteers' skin | Procedure: Diaphragm lift<br>* The purpose is to generate the stretch of the peripheral fibers of the diaphragm, being performed with the patient in the supine position and the physiotherapist standing on the patient's head and Pulling the Your costal arch In the cephalic direction, for one minute, twice<br>* Other names: Diaphragmatic release 1;Procedure: Relaxation of the diaphragm pillars<br>* Second technique aims to promote the rhythmic stretching of the double psoas diaphragm pillars, being performed with The patient in the ventral position and the therapist standing at his side placing the ulnar border of his cephalic hand on the last ribs and his caudal hand flattened in front of the popliteal fossa of the popliteal fossa, stretching was done for one minute<br>* Other names: Diaphragmatic release 2;|
