Neck Grasp as a Predictor of Sleep Apnea
Neck Grasp as a Predictor of Sleep Apnea
A previous pilot study on the use of self neck grasp, ESAP (Easy Sleep Apnea Predictor),
 showed a positive maneuver (unable to wrap hands completely around neck) to be 100%
 predictive of sleep apnea in a sleep clinic population. The investigators now would like to
 compare ESAP to other tests used to diagnose and screen for Sleep Apnea in type 2 diabetics.
 The tests will included Home Sleep Testing, sleep questionnaires Berlin and STOP-BANG and
 polysomnogram (PSG). Patients with type 2 diabetes in the Bassett Endocrine Clinic who are
 scheduled for a routine evaluation will be recruited to undergo; a Home Sleep Test along with
 two sleep questionnaires PSG. The screen test wil be compared to the results of the gold
 standard diagnostic test the PSG for their predictive value os OSA in the type 2 diabetic
 population.
The goal is to evaluate the ESAP study (simple neck grasp) as a predictor of Obstructive
 Sleep Apnea (OSA) in combination with, and in comparison to; Home Sleep Test ( HST), Berlin
 Sleep Questionnaire and STOP-BANG questionnaire. All predictors are being evaluated against
 the gold standard test, the polysomnogram (PSG).

 OSA is the common disorder affecting 3-7% of the adult population. It has many negative
 health consequences such as; cardiovascular disease, diabetes, motor vehicle accidents and
 depression. Data from both epidemiological and clinical studies suggest that OSA is also
 independently associated with alterations in glucose metabolism and places patients at an
 increased risk of the development of type 2 diabetes It is often missed in a busy practice.
 This simple diagnostic tool may help us in identifying the patient at an earlier stage, thus
 also helping to prevent further complications in diabetic patients.

 Participants will undergo 3 study visits/procedures:

 Visit 1: Participants will be consented for the study, undergo the ESAP test, complete the
 Berlin Sleep Questionnaire & STOP-BANG questionnaire, and provide medical history/demographic
 information.

 Visit 2: Participants will undergo a PSG at the Bassett Sleep Lab.. Visit 3: The morning the
 PSG is completed, participants will be given the HST recorder and instructed in its use in
 order to complete the HST. Participants can then drop off the HST recorder at any Bassett
 Clinic and it will be returned to the Sleep Lab in Cooperstown.

 The ESAP test, Berlin Sleep Questionnaire, and the STOP-BANG Questionnaire will be
 administered by a study coordinator, research nurse, and/or research assistant. The PSG and
 the HST will be read and evaluated by independent evaluators/physicians. These physicians
 will not have access to the ESAP or the questionnaire results prior to the evaluation of the
 PSG or HST.

 If a participant has any test (except the ESAP test alone) that is indicative or suspicious
 for OSA, a study physician will review these results and advise them of any further follow up
 recommendations.
