Study the Effectiveness of Combined Manual Therapy and Pulmonary Exercises on Ventilatory Function in Patients with Restrictive Lung Diseases

This research investigates the effect of selective manual therapy techniques on chest expansion, pulmonary function (FVC, FEV1, and FEV1/FVC ratio), and functional capacity, in restrictive lung disease patients. The research hypothesis will be that no statistically significant difference would be found between manual therapy combined to conventional treatment and conventional treatment alone in restrictive lung disease patients.
