Effect of Inspiratory Muscle Training in Obstructive Sleep Apnea Syndrome.

Sleep apnea-hypopnea syndrome is a sleep-related respiratory disorder characterized by partial or total interruptions in breathing during sleep. The majority of syndromes involve an obstructive mechanism (OSA), caused by a reduction in the caliber of the upper airway (UA), most often associated with hypotonia of the surrounding muscles, preventing air from entering the UA during inspiration. The clinical consequences of this syndrome are excessive fatigue and daytime sleepiness, which have a negative impact on the quality of life of patients. Despite the positive results on apnea-hypopnea index and daytime sleepiness of continuous positive airway pressure (today's reference treatment), its 3-year compliance rate (i.e 59.9% according to a study by Abdelghani et al points to the need to develop other associated therapies. Several studies have demonstrated the efficacy of physiotherapy, such as physical activity and oro-pharyngeal muscle strengthening, notably on the apnea-hypopnea index and daytime sleepiness measured by the Epworth scale. Few studies have investigated the effect of inspiratory muscle training (IMT), even though the use of the inspiratory musculature (i.e. the diaphragm) is a means of supplementing the peri-pharyngeal muscles, as it helps to maintain the permeability of the upper airways. Inspiratory muscle training (IMT) could therefore be considered as part of the physiotherapeutic management of the OSA. The heterogeneity of current results concerning IMT …
