Primary Outcome Measures

Name	Time	Method
<p>To construct an algorithm for detection of cardiac arrest related falls using<br /><br>wrist-derived accelerometer signals from simulated sudden falls and non-fall<br /><br>movements and study the sensitivity and specificity of the developed algorithm. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>1. To study wrist-derived accelerometry signal characteristics in relation to<br /><br>sudden falls, soft falls and non-fall-motions in healthy subjects who simulate<br /><br>falls.<br /><br>2. To study positive and negative predictive value of the algorithm for sudden<br /><br>falls.<br /><br>3. To study sensitivity and false positives of an algorithm to detect soft<br /><br>falls.<br /><br>4. To identify sources of noise interfering with correct accelerometry-based<br /><br>measurement of movements.<br /><br>5. To study false positive rates of the recently developed first PPG-based<br /><br>cardiac arrest detection algorithm (DETECT-1) in this controlled study setting<br /><br>6. To validate the steps per minute recorded by the CardioWatch by the steps<br /><br>per minute recorded by the CE/FDA certified Actigraph.<br /><br>7. To validate the active calories per minute recorded by the CardioWatch by<br /><br>the active calories per minute recorded by the CE/FDA certified Actigraph.</p><br>
