Effects of SIMEOX on Static Hyperinflation in Patients With COPD

Short-term Effects of SIMEOX on Static Hyperinflation in Patients With Chronic Obstructive Pulmonary Disease

This study will investigate the effects on the SIMEOX technology on static hyperinflation in patients with chronic obstructive pulmonary disease (COPD).

This is a crossover study assessing the short-term effects of SIMEOX and PEP device on static hyperinflation in patients with COPD.

Patients will perform lung function tests (to assess the residual volume and functional residual capacity) before, after and 30 minutes after a 20-min long session of SIMEOX or PEP (depending of randomization).

Inclusion Criteria:

• Patients with chronic obstructive pulmonary disease,
• Forced expiratory volume in 1s (FEV1) <80% of predicted value,
• Stable condition (no pulmonary exacerbation for more than 28 days).

Exclusion Criteria:

• Routine use of one of the two treatments - SIMEOX and/or PEP,
• Inability to understand or carry out the instructions,
• Severe cardiac comorbidity, neuromuscular disease,
• Severe scoliosis,
• Patient with a pacemaker.
