The objective of the present study was to develop a scientifically sound rationale for the application of the pulsed low-frequency electrostatic fields (PLIESF) for the combined treatment of the children presenting with bronchial asthma and the comparative assessment of the effectiveness of the use of this method either as monotherapy or together with therapeutic physical exercises based on the immediate and long-term results of the treatment. The dynamic clinical observations and special investigations were carried out on 101 children at the age varying from 5 to 15 years who suffered from bronchial asthma. PLIESF were shown to produce the beneficial effect on dynamics of clinical symptoms in the children manifested as the disappearance or reduced frequency of episodes of laborious respiration and the improvement of sputum discharge, auscultation picture, bronchial patency, and respiratory excursions of the chest. The application of PLIESF significantly increased the level of the general physical performance in the children with bronchial asthma, improved the functional conditions of the cardiovascular system, normalized both the cardiac rhythm and the heart rate. It was shown based on the analysis of the short-term and long-term outcomes of the treatment that the combined therapy with the use of the two physical factors, i.e. the pulsed low-frequency electrostatic fields and therapeutic physical exercises, ensures the significantly higher effectiveness of the treatment than the separate application of either of them.
