Deep lung insufflation training improved maximum insufflation capacities (MICs) and assisted peak cough flows (PCFs) in patients with neuromuscular disease. This intervention enhances cough effectiveness despite disease progression.

Area of Science:

  • Respiratory Physiology
  • Neuromuscular Disorders

Background:

  • Neuromuscular diseases often impair respiratory muscle strength.
  • Reduced vital capacities (VCs) and peak cough flows (PCFs) compromise airway clearance.

Purpose of the Study:

  • To evaluate the impact of deep lung insufflation training on MICs and PCFs.
  • To assess the efficacy of air stacking in patients with neuromuscular disease.

Main Methods:

  • Forty-three patients with neuromuscular disease and VCs < 2,000 mL underwent air stacking training.
  • Vital capacity, MIC, and assisted/unassisted PCF were monitored before and after training.

Main Results:

  • Mean MICs significantly increased from 1,402 mL to 1,711 mL (p < 0.001) in 30 patients.

  • Assisted PCF significantly increased from 3.7 L/s to 4.3 L/s (p < 0.05) in patients with improved MICs.
  • Some patients experienced decreased VCs and unassisted PCFs.

    • Conclusions:

    • Air stacking training can enhance deep lung insufflation capacity.
    • Improved MICs correlate with increased cough effectiveness in neuromuscular disease.
    • This technique offers a potential benefit for airway clearance in affected individuals.
