Background Physicians often experience work-related stress that may lead to personal harm and impaired professional performance. Biofeedback has been used to manage stress in various populations. Objective To determine whether a biofeedback-based stress management tool, consisting of rhythmic breath...

This study sought to determine if individuals with neurological damage can be trained to regulate their emotions through psychophysiological processes and thereby can learn to improve executive functioning and enhance clear thinking. Participants were drawn from AHRC, a community-based structured da...

Originally a remembrance of an elderly physiologist, this paper illustrates the need for a standardized specification of certain experimental or survey conditions beyond those usually necessarily disclosed in conventional publications, namely calendar-dates, clock-times and geographic locations, to...

Of the many new scientific perspectives that emerged from the 20th century, one of the most profound is that the universe is wholly and enduringly interconnected and coherent.1-3 Complex living systems, including human beings, are composed of numerous dynamic, interconnected networks of biological s...

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 ) and deficits in early stage information processi...

Attention-deficit hyperactivity disorder (ADHD) is the most prevalent behavioral diagnosis in children, with an estimated 500 000 children affected in the United Kingdom alone. The need for an appropriate and effective intervention for children with ADHD is a growing concern for educators...

Objectives This study examined whether a group of participants trained in achieving high states of heart rate variability coherence (HRVC) could facilitate higher levels of HRVC in an untrained subject in close proximity. Design Fifteen adult volunteers were trained to increase their HRVC. In a seri...

In 2007, the leadership team at Grinnell Regional Medical Center participated in a pilot project with the Institute of HeartMath (IHM) to assess the stress level of individual team members and its effect on the organization. At the beginning of the project, the leadership team completed a Personal a...
