Wrist-Worn Electrodermal Activity as a Novel Neurophysiological Biomarker of Autonomic Symptoms in Spatial Disorientation.

Spatial disorientation is one of the most frequent causes of aircraft accidents, and is thus a major problem affecting air safety. Although a number of studies have examined spatial disorientation, the precise physiological changes occurring as a direct result of spatial disorientation and motion sickness remain unclear. The present study sought to investigate electrodermal activity (EDA) and subjective autonomic symptoms during spatial disorientation training, and to develop an indicator of physiological changes for pilot candidates.

Introduction: Cardiovascular diseases can lead to sudden in-flight incapacitation and long-term disability in aircraft pilots. Electrocardiogram (ECG) has been widely used to screen for these diseases in routine aeromedical examinations. Several ECG changes such as complete left bundle-branch block (CLBBB) and left ventricular hypertrophy (LVH) have been associated with increased likelihood of underlying structural cardiac diseases in addition to the emergence of newly recognized cardiovascular diseases such as Brugada syndrome.
