Acute clinical benefits of chest wall-stretching exercise on expired tidal volume, dyspnea and chest expansion in a patient with chronic obstructive pulmonary disease: A single case study

Chest physical therapy (CPT) has an important role in a medical team to assist in resolving the critical problems deriving from chronic lung disease.

These critical problems include increased secretion volume, difficult breathing or dyspnea, ineffective coughing, inability to be weaned off a ventilator, and physical deterioration resulting from low aerobic capacity and endurance after prolonged bed rest. The inability to be weaned off a ventilator does not only result from secretion production or muscle weakness, but other conditions including chest stiffness or immobility. The procedure to increase chest mobility includes specific chest stretching and mobilization. Chest wall-stretching exercises were composed of thoracic rotation and anterior compression with stretching in sitting position, trunk extension and rib torsion in supine lying, and lateral stretching in side lying. These exercises were given to the patient as a regular daily program along with postural drainage, percussion, breathing exercise and limb exercises. The expired tidal volume, dyspnea level, and chest expansion were evaluated and clinical efficiency was analyzed during CPT, compared to Pre-CPT and Post-CPT with Bloom table. The results showed a significant clinical improvement of expired tidal volume, reduction in dyspnea level, and increase in chest expansion.
