Brief Summary:
Comparison of the NightBalance Sleep Position Trainer (SPT) to Positive Airway Pressure (PAP) for the Treatment of Positional Obstructive Sleep Apnea (POSA). Primary Objective: Efficacy and Adherence of the SPT over 3 months of use compared to PAP for the treatment of POSA. The study is run from centers in France, the UK and Germany.

Condition or disease Intervention/treatment Phase
Obstructive Sleep Apnea Device: NightBalance Sleep Position Trainer (SPT) Device: Automatic Positive Airway Pressure (APAP) Not Applicable

Detailed Description:
Participants are randomly allocated to receive one of two treatments, either Automatic Positive Airway Pressure (APAP) or NightBalance Sleep Position Therapy for a three month period. Participants are sent home with instructions to use that device nightly at home for three months. After three months of using the first device, they return to the doctor for assessment of the efficacy of the device using a sleep test and the compliance read from the device. Upon conclusion of the first three month treatment period, patients receive the alternative treatment for a further three months. At the end of the second three month period, participants return to their doctor again to assess the efficacy of the last device and read the compliance. Before any treatment and after each treatment, patients undergo a sleep test and complete some questionnaires. During each treatment period, patients complete a healthcare utilization diary and report any problems.

Arm Intervention/treatment
Experimental: NightBalance Sleep Position Therapy
NightBalance Sleep Position Trainer (SPT) avoids POSA patients from sleeping on their back by delivering a vibrational stimulus, via a small device which is worn in a chest strap during sleep, each time the patient rolls to their back. This prompts the patient to roll over onto their side.

Experimental: Positive Airway Pressure (APAP)
Automatic Positive Airway Pressure (APAP) is a pump that provides a positive flow of air to keep the airway open.

Primary Outcome Measures :
  1. Change of Apnea-Hypopnea Index (AHI) [ Time Frame: Baseline,3 months and 6 months ]
    Efficacy will be measured as Change of Apnea-Hypopnea Index (AHI) from baseline to 3 months and from 3 months to 6 months (NightBalance SPT non-inferior to PAP)

  2. Difference of the total hours medical device use between each treatment arm [ Time Frame: 3 months and 6 months ]
    Adherence will be measured as the difference between the total hours medical device use from baseline to 3 months and from 3 months to 6 months (NightBalance SPT superior to PAP)


Secondary Outcome Measures :
  1. Daytime Sleepiness [ Time Frame: Baseline,3 months and 6 months ]
    Daytime sleepiness is measured using Epworth Sleepiness Scale (ESS). Epworth Sleepiness Scale (ESS), has a minimum value 0, maximum value 24 with higher values indicate worsening daytime sleepiness.

  2. Impact of sleepiness on activities of daily living [ Time Frame: Baseline,3 months and 6 months ]
    Impact of sleepiness on activities of daily living is measured using Functional Outcomes of Sleep Questionnaire (FOSQ). The FOSQ is a sleep related quality of life is measured across five dimensions; activity level, vigilance, intimacy and sexual relationships, general productivity, social outcome. Each rate the difficulty of performing a given activity on a 4-point scale, min value 0, max value 4. Low scores indicate no difficulty, higher scores extreme difficulty.

  3. Health related quality of life [ Time Frame: Baseline,3 months and 6 months ]
    Health related quality of life is measured using EQ-5D at baseline and at the end of each 3 month treatment arm. Health status is measured in terms of five dimensions (5D); mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has five response levels: no problems, slight problems, moderate problems, severe problems, unable to/extreme problems. Responses are coded as single-digit numbers. The digits for the five dimensions can be combined in a 5-digit code that describes the respondent's health state with lower scores indicting worsening health status and higher values improved health status.

  4. Fatigue [ Time Frame: Baseline,3 months and 6 months ]
    Fatigue is measured using Pichot Fatigue Scale at baseline and at the end of each 3 month treatment arm. The Pichot Fatigue Scale is an 8 question survey in which is answered 0 to 4 with a maximum score of 32. A score above 22 reveals excessive fatigue, patients may suffer from inefficient sleep.

  5. Quality of life utilizing SF-36 [ Time Frame: Baseline,3 months and 6 months ]

    Quality of life is measured using SF-36 at baseline and at the end of each 3 month treatment arm. The 36-Item Short Form Health Survey (SF-36) is an indicator of overall health status. It has the following sections: Vitality, Physical functioning, Bodily pain, General health perceptions, Physical role functioning, Emotional role functioning, Social role functioning, Mental health.

    The SF-36 has eight scaled scores; the scores are weighted sums of the questions in each section. Scores range from 0 - 100. The lower scores mean more disability, and higher scores mean less disability.


  6. Mean Disease Alleviation [ Time Frame: 3 months and 6 months ]
    Mean Disease Alleviation is calculated using the AHI and adherence data at the end of each 3-month treatment arm 8. Adverse events are recorded at the end of each 3-month treatment arm

  7. Health Economics and Resource Utilization [ Time Frame: 3 months and 6 months ]
    Health Economics and Resource Utilization are assessed using healthcare utilization diary which is completed by patients during each 3-month treatment arm.
