Wearable Devices and SUDEP Risk Assessment

June 19, 2020
Our partners at CURE provide a summary on the abstract “Post‐ictal accelerometer silence as a marker of post‐ictal immobility”

Wearable Devices and SUDEP Risk Assessment: An accelerometer (ACC) is a wearable device that measures motion during a convulsive seizure. This study now shows that the “silence” recorded by ACCs after a seizure is a reliable indicator of “postictal immobility” (PI) which is the absence of motion following a seizure. PI has been associated with potentially life-threatening complications, including SUDEP.

 

Post-Ictal Accelerometer Silence as a Marker of Post-Ictal Immobility

Abstract, published in Epilepsia

Objective: Movement-based wearable sensors are used for detection of convulsive seizures. The identification of the absence of motion following a seizure, known as post-ictal immobility (PI), may represent a potential additional application of wearables. PI has been associated with potentially life-threatening complications and with sudden unexpected death in epilepsy (SUDEP). This study aimed to assess whether wearable accelerometers (ACCs) could be used as a digital marker of PI.
