Abstract
Asthma is a major public health problem worldwide, which when uncontrolled, can severely limit the patient’s daily life. Between 300 and 400 million people worldwide suffer from asthma and about 250,000 people die each year. Physical therapy research is recommended to find techniques as substitutions or complementary for medications to reduce its use, dose and/or side effects. To measure the efficacy of bilateral non-invasive cervical vagus nerve stimulation (nVNS) on ventilatory functions and perceived exertion of dyspnea in acute exacerbation of patients diagnosed with bronchial asthma. 52 subjects divided to 10 normal and 11 diagnosed with bronchial asthma not in(acute attack) both 21 subjects were involved as a pre request to assess safety efficacy and any adverse effect of VNS both groups underwent pulmonary functions test (flow-volume curve)to measure (FVC,FEV1,PEF and FEF25-75 as % of predicted after that 31 patients in(acute attack) aged between 21-70 years were assigned randomly into two groups 2/1ratio: VNS group (I) 21 patients and sham VNS group (II) 10 patients both groups underwent pre and post treatment pulmonary functions test (flow-volume curve)to measure parameters of (FVC, FEV1, PEF and FEF25-75%) as % of predicted and modified borg scale of dyspnea(MBSD) to rate difficulty of breathing, group (I) treated with VNS and group (II) with sham VNS for 20 minutes
