Abstract
Objective: To evaluate the effect of of myofascial release for intercostal muscles and diaphragm on diaphragmatic excursion and ventilatory functions in post surgical pleural effusion. Background: Accumulation of fluid in pleural space may decrease function of respiratory muscles primarily because of increase of chest wall volume. Force-length relationship of respiratory muscles indicate that for a given neural activation, the pressure developed by muscles decrease with decreasing length. An increase of chest wall volume decrease length of inspiratory muscles mainly diaphragm and increase of expiratory muscles length. So, the aim of this study to maintain flexibility of intercostal muscles and diaphragm in order to get the optimum action of these muscles, increase diaphragmatic excursion and improve the ventilatory function of these patients. Subject and Methods: Forty volunteers (men only), their age ranged between 45-60 years old, their BMI ranged between (25-29.9) and they were randomly assigned into two groups equal in number. (Study group A): Was enrolled in the myofascial release protocol for intercostal muscles and diaphragm in addition to traditional physical therapy program for pleural effusion. (Study group B): was enrolled in the traditional physical therapy program for pleural effusion only. Their diaphragmatic excursion and ventilatory functions (FVC, FEV1, FEV1/ FVC ) were measured before and after 8 weeks of training program for both groups
