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

There is a long history of pre-deployment PTSD prevention efforts in the military and effective pre-deployment strategies to prevent post-deployment PTSD are still needed. Materials and Methods: This randomized controlled trial included three arms: heart rate variability biofeedback (HRVB), cognitive bias modification for interpretation (CBM-I), and control. The hypothesis was that pre-deployment resilience training would result in lower post-deployment PTSD symptoms compared with control. Army National Guard soldiers (n =

Objective:The aim of this study is to examine a resilience training intervention that impacts autonomic responses to stress and improves cardiovascular risk, psychological, and physiological outcomes in police. Methods: Officers [(n=38) 22 to 54 years] modified emotional and physical responses to stress using self-regulation. Measurements include psychological and physiological measures [eg, heart rate variability (HRV), blood pressure, C-reactive protein)] obtained at three time intervals. Results: Age was significantly (P<0.05) associated with

Police Special Forces (a.k.a. special weapons and tactics [SWAT]) officers are tasked with responding to the most critical situations, including incidents that require specialized skills and equipment beyond typical policing activities. In this study, we tested the feasibility of applying Arnetz and colleagues’ resilience promotion training that was developed for patrol officers to SWAT team officers (n = 18). The resilience promotion training program included psychoeducation focused on police stress and resilience, and the practice of resilience

The objective of this case study was to test the impact in law enforcement personnel of an innovative self-regulation and resilience building program delivered via an iPad (Apple Inc, Cupertino, California) app and personal mentoring. The Stress Resilience Training System (SRTS) app includes training on stress and its effects, HRV coherence biofeedback, a series of HeartMath self-regulation techniques (The Institute of HeartMath, Boulder Creek, California), and HRV-controlled games. The stressful

Objective: Chronic pain is an emotionally and physically debilitating form of pain that activates the body’s stress response and over time can result in lowered heart rate variability (HRV) power, which is associated with reduced resiliency and lower self-regulatory capacity. This pilot project was intended to determine the effectiveness of HRV coherence biofeedback (HRVCB) as a pain and stress management intervention for veterans with chronic pain and to estimate the effect sizes. It was hypothesized that

Background • The need for treatment of posttraumatic stress disorder (PTSD) among combat veterans returning from Afghanistan and Iraq is a growing concern. PTSD has been associated with reduced cardiac coherence (an indicator of heart rate variability [HRV]) and deficits in early stage information processing (attention and immediate memory) in different studies. However, the co-occurrence of reduced coherence and cognition in combat veterans with PTSD has not been studied before. Primary Study Objective • A pilot study was

This study investigated the impact of a new stress management program on physiological and psychological stress and health risk factors among 75 correctional officers. The experimental group received training in emotion self-regulation techniques intended to reduce stress and health risk factors. Practice of the techniques was enhanced by heart rate variability feedback, which helped participants learn and sustain use of the self-management tools. Measures of physiological stress included cortisol, DHEA, cholesterol, triglycerides, fasting glucose
