Manual Therapy in Patients With Asthma

Study Overview
=================
Brief Summary
-----------------
Physical therapists have traditionally included various forms of manual therapy among the therapeutic approaches to respiratory conditions. The aim of this study was to evaluate the effect of diaphragmatic stretching technique on pulmonary ventilation, rig bage excursion and spirometric values in patients diagnosed with asthma.

Detailed Description
-----------------
Asthma is a chronic lung disease involving an inflammation and a narrowing of the airways. Asthma causes wheezing, chest tightness, shortness of breath, and coughing. A variety of manual therapies are commonly used to treat patients with asthma. There is a need to conduct studies in order to examine the effects of manual therapies on clinically relevant outcomes. Techniques aim to increase movement in the rib cage and the spine to try and improve the working of the lungs and circulation.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Diaphragm stretching<br>30 Patients with asthma are included in this group. They will receive a diaphragm stretching technique | Other: Diaphragm stretching<br>* The therapist stands behind the patient and passes his hands around the thoracic cage, carefully introducing fingers under the costal margins. The patient slightly rounds the trunk in order to relax rectus abdominis. During the exhalation of the patient the therapist grasps the lower ribs and costal margin and eases the hands caudally. This traction was maintained during 5-7 minutes.<br>* Other names: Manual therapy;|
| Placebo Comparator: Placebo group<br>Ultrasound disconnected in same position and with the same duration. | Other: Placebo<br>* The same therapist, patient position and duration of the technique, but using disconnected ultrasound<br>* Other names: Disconnected ultrasound.;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Forced vital capacity | The amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. It is going to be measured using a spirometer as recommended by the American Thoracic Society. | Baseline, 7 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Abdominal Kinematics | Abdominal kinematic measurements can be used as an evaluative method to quantify possible alterations in abdominal movements. | baseline, 7 days | 
| Airway diffusing capacity | The airway diffusion capacity will be measure using the deep breeze device. This is a non-invasive and radiation-free gadget that provides a dynamic image of the lungs, delivering both structural and functional information. | baseline, 7 days | 
| Forced expiratory volume in the first second | This is the amount of air which can be forcibly exhaled from the lungs in the first second of a forced exhalation. It is going to be measured using a spirometer as recommended by the American Thoracic Society. | baseline, 7 days | 
| Rib cage excursion | Rib cage excursion can be used as an evaluative method for diaphragmatic breathing excursion to quantify possible alterations in thoracic capacity and chest wall compliance as achieved by all expiratory and inspiratory muscles | baseline, 7 days |
