Brief Summary:
This is a crossover randomized controlled trial comparing a convenient positional therapy (PT) device to continuous positive airway pressure (CPAP) in the treatment of positional obstructive sleep apnea (OSA).

Condition or disease Intervention/treatment Phase
Sleep Apnea Syndromes Device: Night Shift positional device Device: continuous positive airway pressure Not Applicable

Detailed Description:
This study aims to compare a convenient positional therapy (PT) device used for 8 weeks to continuous positive airway pressure (CPAP) used for 8 weeks in patients with positional obstructive sleep apnea (OSA) in a crossover randomized controlled trial.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Night Shift positional device
Randomized to Night shift positional therapy first for 8 weeks, followed by CPAP for 8 weeks, with a 1 week washout period.
 Device: Night Shift positional device
Night Shift is a small, positional therapy device that is worn at the back of the neck using a latex free silicone rubber strap. The strap is adjustable and is secured with a magnetic clasp. When a supine position is detected, the device vibrates with increasing intensity till the subject changes to a non-supine position.
Active Comparator: Continuous positive airway pressure
Randomized to CPAP first for 8 weeks, followed by positional therapy for 8 weeks, with a 1 week washout period.
 Device: continuous positive airway pressure
Automated adjusting continuous positive airway pressure


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Epworth Sleepiness Scale ( ESS) [ Time Frame: 8 weeks after the beginning of each intervention ]
    Difference in sleepiness ( PT minus CPAP) measured by the Epworth Sleepiness Scale ( ESS) after 8 weeks of device use


Secondary Outcome Measures :
  1. Functional Outcomes of Sleep Questionnaire ( FOSQ) [ Time Frame: 8 weeks after the beginning of each intervention ]
    Difference in FOSQ

  2. 36-Item Short Form Survey (SF-36) [ Time Frame: 8 weeks after the beginning of each intervention ]
    Difference in SF-36

  3. Pittsburgh Sleep Quality Index (PSQI) [ Time Frame: 8 weeks after the beginning of each intervention ]
    Difference in PSQI

  4. Apnea-hypopnea Index ( AHI, events/hr) [ Time Frame: 8 weeks after the beginning of each intervention ]
    Difference in AHI

  5. DASS21 questionnaire [ Time Frame: 8 weeks after the beginning of each intervention ]
    Difference in mood symptoms ( DASS21)

  6. Patient adherence ( hours of device use per night) [ Time Frame: 8 weeks after the beginning of each intervention ]
    Compare patient adherence based on device download information

  7. Patient preference [ Time Frame: Upon study completion at week 17 ]
    patient preference for treatment modality will be assessed via a questionnaire

  8. Oxygen desaturation index (3%) and lowest oxygen saturation ( %) [ Time Frame: 8 weeks after the beginning of each intervention ]
    Oxygen indices
