What is the objective of postural drainage?

The objective of postural drainage is to facilitate the removal of excess secretions from the lungs. This therapeutic technique involves positioning the patient so that gravity aids in draining mucus from the bronchial tubes, making it easier for individuals, particularly those with respiratory conditions, to expel secretions. By using specific positions and techniques, healthcare providers can enhance lung function, promote clearer airways, and decrease the risk of infections that can arise from accumulation of secretions.

Other options are related to different areas of rehabilitation or therapy. Improving muscle strength focuses on physical training and resistance exercises rather than on mucus clearance. Encouraging voluntary movement pertains to motor skills and rehabilitation for mobility but does not directly address the respiratory function. Stimulating nerve function relates to neurological rehabilitation strategies, which do not encompass the goals of postural drainage. Hence, facilitating the removal of excess secretions directly aligns with the therapeutic aim of postural drainage.
