Expiratory muscle weakness

WebVital capacity (VC) is an easily obtained measurement with spirometry, which, when decreased, points to respiratory muscle weakness. The VC averages approximately 50 mL/kg in normal adults. However, VC is not specific and may be decreased because of both inspiratory and expiratory muscle weakness and restrictive lung and chest wall diseases. WebExpiratory muscle adaptations have been less comprehensively studied, but it is likely that the expiratory muscles respond to training in a similar manner to the inspiratory muscles. ... Respiratory muscle weakness is a common complication in many neuromuscular and chest wall conditions, and although it may occasionally be a presenting feature ...

WebMEP is measured during a similar maneuver at total lung capacity (TLC) because expiratory muscle strength is directly related to lung volume (again in a curvilinear fashion). The information available from these maneuvers is nonspecific, however, and cannot distinguish between insufficient effort, muscle weakness, and a neurologic disorder. WebDiaphragm weakness in Charcot-Marie-Tooth disease 1A (CMT1A) is usually associated with severe disease manifestation. This study comprehensively investigated phrenic nerve conductivity, inspiratory and expiratory muscle function in ambulatory CMT1A patients.
