Filter by:- Assessment of diaphragmatic function (excursion, thickness variation, thickness ratio) in COPD and bronchial asthma patients. - Assessment of presence of correlation between diaphragmatic dysfunction and pulmonary function. - Assessment of possible association between diaphragmatic dysfunction and presence of reversibility in pulmonary function post bronchodilator.
This is a cross-sectional obsessional study. This study aims (1) to investigate the relationship between sternocleidomastoid muscle recruitment and diaphragm thickness fraction during increasing inspiratory resistance in healthy adults; (2) to compare diaphragmatic and sternocleidomastoid muscle recruitment patterns with and without a standard diaphragmatic breathing instruction with increasing inspiratory resistance in healthy adults. Participants will be asked to breathe through a pressure threshold inspiratory loading device under different inspiratory resistances with and without a standard diaphragmatic breathing instruction. sternocleidomastoid muscle activity will be measured with surface electromyography, and diaphragm thickness will be assessed with ultrasonography.
