Pulmonary physical medicine interventions for elderly patients with muscular dysfunction

The respiratory consequences of respiratory muscle impairment, with or without bulbar muscle weakness, usually involve inadequate ventilation and airway secretion encumbrance and may progress to respiratory failure. This article focuses on muscular dysfunction of the bulbar and respiratory musculature in elderly patients with neuromuscular diseases or central nervous system disorders. In addition, the article discusses application of pulmonary physical medicine principles for patients with predominantly restrictive pulmonary disorders caused primarily by muscular dysfunction. Diagnostic evaluation, respective clinical courses and responses to therapy, and the use of noninvasive ventilatory support outside of an acute care setting are also reviewed.
