Phrenic neuropathy etiologies and recovery trajectories in outpatient rehabilitation and neuromuscular medicine clinics: A retrospective analysis

Phrenic neuropathy (PhN) impairs diaphragm muscle function, causing a spectrum of breathing disability. PhN etiologies and their natural history are ill-defined. This knowledge gap hinders informed prognosis and management decisions. This study aims to help fill this knowledge gap on PhN etiologies, outcomes, and recovery patterns, especially in the context of nonsurgical clinical practice.
