Respiratory Rehabilitation in Obstructive Sleep Apneas

Patients: Eligible patients aged between 40 and 80 years old, with BMI \< 30 and with a recent diagnosis of mild Obstructive Sleep Apnea evaluated with home night cardio-respiratory monitoring. The investigators will exclude patients with one or more of the following conditions: subjects who regularly use hypnoinductive drugs, with craniofacial malformations, who have suffered recent facial trauma, suffering from hypothyroidism, suffering from neuromuscular diseases, with recent strokes, severe obstructive nasal disease, systemic infectious diseases and neoplastic diseases. Home night cardio-respiratory monitoring: all patients will be evaluated according to international guidelines (AAMS American Academy Sleep Medicine) with an instrument equipped with sensors for detection oral/nasal flow, snoring, chest/abdomen movements, pulse oximetry and heart rate. Questionnaire: The investigators will employ questionnaires validated in Italy: Snoring frequency (derived from the Berlin questionnaire); subjective daytime sleepiness (Epworth questionnaire); quality of sleep (Pittsburgh sleep quality questionnaire). Patients will be randomized into two groups randomly with a 1: 1 ratio: group 1 (treated group) or group 2 (control group) for a total of 20 patients per group (according to the sample size calculation reported in the protocol). The treatment group will be subjected to an integrated rehabilitation protocol, composed of Respiratory rehabilitation exercises with diaphragmatic breathing, thoracic mobilization exercises and manual pompage techniques, followed by manual trigger point therapy techniques, (that were identified by palpation following the guidelines provided by Travell and Simons trigger point manual), the accessory inspiratory muscles like pectoralis minor muscle, scapula elevator muscle, Sternocleidomastoid muscle. The integrated rehabilitation protocol will be 45 minutes, 3 weekly sessions for 4 weeks, for a total of 12 consecutive sessions. Also, at every patient will be taught oropharyngeal exercises to perform at home twice a day (the duration of 15 minutes each session) involving in particular exercises for soft palate, tongue, facial and genio-glosso muscle. Both in the treated group and the control group will be given a booklet with the rules for proper sleep hygiene because sleep is influenced by our lifestyle and various environmental factors can affect the quality of night sleep.
