Detailed Description
Obstructive sleep apnea syndrome (OSAS) is a common form of sleep-disordered breathing (SDB) characterized by repetitive episodes of cessation of breathing during sleep due to upper airway collapse. It causes sleep fragmentation, disabling daytime sleepiness, impaired cognitive function and poor quality of life. In addition, OSAS is associated with non-fatal and fatal cardiovascular consequences including sudden death as well as to an increased risk of road traffic accidents. OSAS is a common disease, affecting approximately 2% of women and 4% of men residing in Western communities.
Risk factors for OSAS include obesity, aging, particularly males, abnormal craniofacial morphology, nasal obstruction, and genetic factors. OSAS is associated with several cardiovascular consequences and social consequences such as motor vehicle accidents, impaired cognitive performance, and depression. Various epidemiologic studies have shown an association between OSAS and hypertension. In a cross-sectional study, OSAS was associated with increased prevalence of self-reported heart failures and strokes. OSAS has been shown to be independently associated with coronary artery disease after adjustment for traditionally considered risk factors.
According to the American Medical Association in 2013, obstructive sleep apnea syndrome (OSAS) is a common disorder that affects everyone in all ages, especially middle-aged and elderly people. In fact, evidence showed that OSAS rates had been increasing due to the escalation of obesity rates. Thus, the goal of the OSAS treatment is to alleviate the airway obstruction during sleep. The standard first-line OSAS treatment involves continuous positive airway pressure (CPAP) devices, which deliver compressed air into the airway in order to stay open. In most cases, many patients cannot tolerate CPAP and often are unable to adhere to the instructions for many reasons. Patients began to feel discomfort and claustrophobic as well as skin irritation and noise. Although small studies lack data of other OSAS treatments, this case resulted in insufficient evidence to determine the efficacy of these strategies. In regards to limited data, the evidence is not yet resolved on the effectiveness of the treatment. There is very limited evidence on the clinical outcomes of the OSAS intervention, and most of the data focus on immediate results that are exceedingly direct and provide no long-term benefits. Likewise, evidence in evaluating the relative efficacy of weight loss, oronasopharyngeal exercise and tongue retraining device interventions for OSAS treatment was insufficient. Low-quality evidence indicated that the above interventions improved sleep measures and should be recommended for patients with OSAS.
Purpose:
The aim of the study was to assess the effect of PSG data, Epworth Sleepiness scale (ESS), WHOQOL-BREF questionnaire (EQ-5D), 6-minute walking test (6MWD), rate of perceived exertion scale (RPE), flow-volume loop (FV-Loop), tongue and grasp muscle strengths, anthropometric data and daily note record between two groups (control group: CPAP therapy and experimental group: subgroup have WE, TIMT and TMT therapies) patients with moderate to severe obstructive sleep apnea syndrome (OSAS).
Hypothesis:
The investigators hypothesize that more moderate to severe obstructive sleep apnea syndrome patients in a home-based recovery activity intervention program will have improved PSG data, quality of life, exercise ability, pulmonary function, muscle strength, anthropometric data and daily note record than patients receiving CPAP alone.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Experimental group
Subjects will be in random cluster assign to walking exercise (WE), Threshold Inspiratory Muscle Trainer (TIMT) and Tongue Muscle Trainer (TMT) treatment groups.
|
Subject will be instructed to compress the Iowa Oral Performance Instrument (IOPI) IOPI's bulb using tongue in three directions (anterior and both lateral sides).
Then, hold 30-35 seconds each time.
Subjects will be encouraged to do 60 minutes of exercise daily then continue three to five times a week for a total of 3 months.
Resistance of the TIMT devices will be set from 30% of the maximum inspiratory pressure.
Nose clip follow by normal breathing.
Seal the mouth to the device's mouth piece then inhale through the device.
Subjects will be encouraged to do 60 minutes of exercise daily then continue three to five times a week for a total of 3 months.
Subjects will be encouraged to perform walking exercise in the field 10000 steps/ 60 minutes daily then continue three to five times a week during first months.
Followed by 12500 steps and 15000steps per day during the second and third months.
|
Active Comparator: Control group
Up to 95% of OSAS cases are treated with continuous positive airway pressure (CPAP), CPAP treatment group will be the control group.
|
CPAP regular therapy per day (use ≥ 4 h/day) then continue three to five times a week for a total of 3 months.
