Self-administered Hyperinsufflation Chest on the Risk of Low Respiratory Infection in Patients With Multiple Sclerosis With Sputum Capacity Deficit

During multiple sclerosis (MS), although expiratory involvement and reduced sputum capacity are predominant, automated techniques of hyperinsufflation and in-exsufflation remain underused and undervalued. A single retrospective study suggests a decrease in the decline in respiratory function with regular manual hyperinsufflation. Evidence of a benefit of chest mobilization by hyperinsufflation by a controlled trial is therefore necessary before recommending its use in MS.
