Abstract
Background: Bronchial asthma is considerd a major health problem characterized by a chronic inflammatory disorder of the airways, in which many cells and cellular elements play a role. The global prevalence,morbidity, mortality and eco-nomic burden associated with asthma have increased since the 1970s, particularly in children various methods are used to assess airflow limitation, but two methods have gained widespread acceptance for use in patients over 5 years of age. These are spirometry, particularly the measurement of Forced Expiratory Volume in 1 second (FEV1) and Forced Vital Capacity (FVC), and peak flow meter.
The chronicity of bronchial asthma and the fear of steroid therapy cause many patients to seek alternative methods of treatment such as (physical therapy modalities, acupuncture and herbal medicine).
The purpose of the study: To investigate if there difference between the effect of frolove device versus pursed lip breathing exercises on ventilatory functions in patients with bronchial asthma.
Methods: A prospective, randomized, controlled trial was conducted on 36 asthmatic females involved in this study. The participants had at least three year's history of bronchial asthma. Their ages ranged (35-55) years. Their body mass index ranged (31-37Kg/m2). They were divided into two equal groups (Frolov and pursed lip). FEV1, FVC, FEV1/FVC, MVV and ACT were measured in both groups in the initial examination at the beginning of the study, and at the end of the study. The frolov Group (A) received training by frolov device for at least 20 minutes, two sessions a week, for 8 weeks. The pursed lip Group (B) received pursed lip brathing exercise for at least 20 minutes, two sessions a week, for 8 weeks.
Results: The results of this study revealed significant changes in all variables in Group (A) as FEV1 improved (30.85%T), FVC improved (26.08%T), the ratio of FEV1 to FVC improved (3.92%T), MVV improved (30%T) and the ACT improved (26.09%T). While in Group (B) the results showed a significant changes in FEV1 (20.22%T) and FVC (14.41%T), but there was no significant changes in the ratio of FEV1 to FVC (4.48%T), MVV improved (19.38%T) and the ACT improved (27.66%T).
Conclusion: Frolov breathing device for two months had obvious benefits in improving ventilatory functions levels and controlling asthma than pursed lip breathing.
