Psychophysiological coherence training to moderate air traffic controllers’ fatigue on rotating roster

The nature of the current rotating roster, providing 24-h air traffic services over five irregular shifts, leads to accumulated fatigue which impairs air traffic controllers’ cognitive function and task performance. It is imperative to develop an effective fatigue risk management system to improve aviation safety based upon scientific approaches. Two empirical studies were conducted to address this issue. Study 1 investigated the mixed effect of circadian rhythm disorders and resource depletion on controllers’ accumulated fatigue. Then, study 2 proposed a potential biofeedback solution of quick coherence technique which can mitigate air traffic controllers’ (ATCOs’) fatigue while on


Psychophysical Coherence Training Regulating Air Traffic Controller's Heart Rate Variability and Resilience to Fatigue

Published on: 23-08-2021

Abstract. Heart Rate Variability (HRV) can reflect individuals’ cognitive workload objectively. HRV measurement is a non-invasive method to evaluate relevant physiological changes in a human body. Physiological changes and cognitive processes are associated with the cardiac dynamic autonomic control, and thus to influence individuals’ ability to cope with fatigue and achieve resilience. As a dynamic process to be learned, resilience can be formed and improved through Quick Coherence Training in a short time. To study the regulatory effects of


Heart rate variability biofeedback in chronic disease management: A systematic review

Background: Heart rate variability biofeedback (HRVB) is a non-pharmacological intervention used in the management of chronic diseases.
Method: A systematic search was performed according to eligibility criteria including adult chronic patients, HRVB as main treatment with or without control conditions, and psychophysiological outcomes as dependent variables.
Results: In total, 29 articles were included. Reported results showed the feasibility of HRVB in chronic patients without adverse effects.


Heart Rate Variability Biofeedback Improves Emotional and Physical Health and Performance: A Systematic Review and Meta Analysis

We performed a systematic and meta analytic review of heart rate variability biofeedback (HRVB) for various symptoms and human functioning. We analyzed all problems addressed by HRVB and all outcome measures in all studies, whether or not relevant to the studied population, among randomly controlled studies. Targets included various biological and psy-chological problems and issues with athletic, cognitive, and artistic performance. Our initial review yielded 1868 papers, from which 58 met inclusion criteria. A significant small to moderate effect size was found favoring HRVB, which does not differ from that of other effective treatments. With


Stress Management Based on Trait-Anxiety Levels and Sleep Quality in Middle-Aged Employees Confronted with Psychosocial Chronic Stress

A  stress  management  program  using  cardiac  coherence  was  implemented  after  an  organizational  down-sizing. The study was conducted in nine voluntary workers in order to evaluate the efficiency of the program.  A  baseline  evaluation  was  conducted  on  psychological  variables  (anxiety,  perceived-stress,  well- being  and  sleep),  endocrine  assessments  (urinary  cortisol  excretion,  alpha-amylase  and  salivary  concentrations)  and  physiological  recordings  (sleep  and  heart  rate  variability).  The  low  number  of
