Clinical Trial Summary

Objective: To investigate the effectiveness of core stabilization exercises combined with the patient education program (AEP) and breathing exercises in patients with asthma.

Design: A randomized controlled study Setting: Chest diseases clinic of a university hospital. Subjects: The study sample consists of 26-68 years old asthma patients who were diagnosed at least 6 month prior to the study.

Interventions: All subjects were included in the asthma education program (AEP) and both groups were trained for diaphragmatic and pursed lip breathing exercises (2times/wk. 6-week duration at clinic). The core stabilization program was applied twice a week for a duration of 6 weeks in TG.

Main Measures: Spirometry, maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), International Physical Activity Questionnaire Short Form (IPAQ), Hospital Anxiety and Depression Scale(HADS), Asthma Quality of Life Questionnaire(AQOL), Six-minute walking test(6MWT), Prokin PK200, Italy were used to evaluate feasibility of interventions.

Description:

All volunteers received an asthma education program (AEP) and trained for diaphragmatic and pursed lip breathing exercises. Additionally, the TG participated in the core stabilization exercises program combined with AEP and breathing exercises. Data were collected from all the patients at baseline and post interventions (6 week) by the same physiotherapist who also supervised the exercise sessions.

All subjects were included in the asthma education program (AEP). AEP was performed at least once for approximately 20 minutes via face to face interviews. Education topics covered description of asthma, physiological changes of lungs, risk factors, treatment methods, relaxation positions to reduce dyspnea and usage of a specific inhaler. Breathing exercises were comprised of instructing breathing control, diaphragmatic breathing and pursed lip breathing exercises. Participants attended breathing exercises training for 2 days at the clinic under the supervision of a physiotherapist and 3 days at home as a home-exercise program. Total duration of breathing exercises lasted for 6 weeks. TG performed core stabilization exercises combined with breathing control for 2 days/a week for the duration of 6 weeks under the supervision of a physiotherapist at the clinic. Basic knowledges on spine, muscles of core stabilization and working principle of diaphragm and biofeedback unit (SPB) (Chattanooga Stabilizer Pressure Biofeedback, USA) were explained before the training. The SPB consists of an inflation pump and a cell like sphygmomanometer, which reflects body spinal movement in terms of mmHg by changing pressure in air filled cells. The SPB was placed under the lumbar 5th vertebra and patients attempted to maintain their core stability performing neutral zones at the settled level of 40 mmHg pressure. Furthermore, physiotherapist tried to improve thoracolumbar awareness by following changes from SPB and volunteers assured a constant lumbar position during upper and lower extremity movements combined with diaphragmatic movements. The 6 week exercise protocol emphasized core muscle co-contraction in hook-lying position with a flat cushion between two knees to provide integration between the pelvic floor muscles and diaphragm. Subsequently, exercises progressed as diaphragmatic breathing, flexion of both shoulder with breathing control and extending knees bilaterally with breathing control. Moreover, the hold time and the number of repetitions were increased from 5 repeats x 1 set to 5 repeats x 4 sets and each session lasted 20 minutes.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Inspiratory Pressure	The Micro Medical Micro RPM, England respiratory pressure meter was used to measure respiratory muscle strength	Six Weeks
Primary	Functional Capacity Test	The Six Minute Walking Test was used to evaluate functional capacity of volunteers. 6MWT was performed on a 30 meter corridor in the clinic according to American Thoracic Society guidelines. Walking distance was calculated.	Six Weeks
Primary	Forced vital capacity in 1 second (FEV1)	Medical International Research Spirodoc® Spiro, Italy brand named spirometry was used to evaluate pulmonary functions of volunteers.	Six Weeks
Primary	Quality of life	Asthma Quality of Life Scale (AQOL) was utilized to assess quality of life of participants over two weeks prior to the interview which was validated for the Turkish population.l	Six Weeks
Primary	Maximum Expiratory Pressure	The Micro Medical Micro RPM, England respiratory pressure meter was used to measure respiratory muscle strength	Six Weeks
Primary	Functional Vital Capacity (FVC)	Medical International Research Spirodoc® Spiro, Italy brand named spirometry was used to evaluate pulmonary functions of volunteers.	Six Weeks
Primary	Tiffeneau Ratio (FEV1/FVC)	Medical International Research Spirodoc® Spiro, Italy brand named spirometry was used to evaluate pulmonary functions of volunteers.	Six Weeks
Primary	Forced Expiratory Flow from 25 % to 75 % of Vital Capacity (FEF25-75)	Medical International Research Spirodoc® Spiro, Italy brand named spirometry was used to evaluate pulmonary functions of volunteers.	Six Weeks
Secondary	Physical Activity	International Physical Activity Questionnaire Short Form (IPAQ) was used to determine physical activity status.The total score of IPAQ is calculated by summation of the duration (in minutes) and frequency (days) of three physical activities.	Six Weeks
Secondary	Depression level	The valid and reliable version of the Hospital Anxiety and Depression Scale (HADS) for the Turkish population was utilized to determine depression level.	Six Weeks
Secondary	Anxiety level	The valid and reliable version of the Hospital Anxiety and Depression Scale (HADS) for the Turkish population was utilized to determine anxiety level.	Six Weeks
Secondary	Dynamic balance	Dynamic balance alterations of the subjects were assessed by TechnoBody Prokin PK 200 (PK), Italy dynamic balance instrument. PK is a circular mobile balance assessment platform like conventional rocker board. PK transmits data from platform to the computer with a wireless transmitter and it can detect each single angular movement with a chip inside the platform. Additionally, PK has four different applicators (easy, medium, hard and rectangular) to place under the mobile platform. The bipedal position for 30 seconds with the easy applicator during the dynamic balance test was used. PK is connected to a computer; in this way each single movement is recorded by a computer in real time mode.	Six Weeks
