intelligent, but the one most responsive to change.”
-Charles Darwin
The overall goal of the ECU Wounded Warrior Program is to increase performance and promote functional independence. The program involves methods to help
Marines learn how to control physical and emotional reactions to stress (resiliency), as well as techniques to increase strength, endurance, cognitive performance, social and life skills.
The program involves sessions both at Camp Lejeune and at the Biofeedback Clinic at East Carolina University.
PTSDWhen a person is exposed to extreme stress such as sexual abuse, war, or even the extended effects of a natural disaster, clinically significant symptoms often emerge.
The existence, frequency, intensity, and duration of these symptoms are dependent upon many factors, including, gender, age, and ethnic background of the person exposed to the stressor as well as the person’s social environment and ability to employ coping strategies.
Specific emotional and behavioral responses to stress have been observed and studied by mental health professionals in multiple settings, under different circumstances, over time. These symptoms have become the clinical indicators used for identifying the stress related disorder known as posttraumatic stress disorder (PTSD).
APA categorizes PTSD symptoms into three main clusters:
1.A traumatic event that is persistently re-experienced; 2.A persistent avoidance of stimuli associated with the trauma and 3. A numbing of general responsiveness and persistent symptoms of increased arousal. The symptoms must last at least one month and adversely affect normal functioning.
“the development of characteristic and persistent symptoms along with difficulty functioning after exposure to a life-threatening experience”. These persistent, post trauma symptoms were the basis for the development of the original PTSD diagnosis in 1980 and with some modification still serve as the diagnostic criteria. While this classification system is a useful is has some limitations such as the exclusion of some less common cognitive, emotional, behavioral and physiological-somatic symptoms.
• Inescapable Shock • Autonomic Nervous System • Sympathetic• Parasympathetic • Learned Helplessness • Defense Defeat Model
• Possible bipolar effect with parasympathetic becoming dominant and then sympathetic rather than rhythmic
Exposure of rhythmic environments to chemical or behavioral stressors can result in increases and decreases in the response (Antleman (1996, 1997)
Possible innate biological function designed to reset the rhythm
Sympathetic Dominance can produce: muscle bracing, bruxism, occular
divergence, tachycardia, diaphoresis, pallor, tremor, startle, hypervigilance, panic rage and constipation
• Symptoms of palpitations, nausea, dizziness, indigestion, abdominal cramps, diarrhea, and incontinence
• Self perpetuating symptoms causing continued dysregulation “free falling”
“The syndrome of trauma has now literally taken control of the body”
The ANS plays an important role in the development and maintenance of a wide range of somatic and mental diseases
In general autonomic imbalance and decreased parasympathetic tone may be the final common pathway linking negative affective states and ill health (Thayer & Brosschot, 2005)
Symptoms of dissociation mimic the bipolar nature of the defining symptoms of PTSD (arousal, reexperiencing, avoidance).
Altered perception of time, space, sense of self and reality.
Emotional Expressions can range from panic to numbing and catatonia.
Altered sensory perceptions may vary from anesthesia to analgesia to intolerable pain.
Motor problems include weakness, paralysis, and ataxia as well as tremors, dysarthia, shaking, and convulsions.
Cognitive Symptoms include confusion, dysphasia, dyscalculia, and extreme attentional deficits.
Perceptual symptoms include ignoral and neglect
Memory alterations may appear as hyperamnesia (Flashbacks), fugue states or selective traumatic amnesia.
Endogenous opiate reward systems contribute to the establishment of conditioned procedural memory in trauma.
Exposure to war trauma often results in a sustained period of analgesia (soldiers in wounded in battle require lower doses of morphine than in other non-combat related wounds)
Stress can induced analgesia in many forms of trauma
Relates to facts and events Plays an important role in conscious
recall of traumatic events) Involves the hippocampal and prefrontal
cortical pathways (inaccurate and subject to decay)
acquisition of new motor skills and habits to the development of emotional memories and associations, and to the storage of conditioned sensorimotor responses. Unconscious, implicit, and extremley resistant to decay when linked to emotional or threat based interventions. (Scaer, 2001)

“environmental demands tax or exceed the adaptive capacity of an organism, resulting in psychological or biological changes that may place persons at risk for disease.”
Cohen, Kessler & Gordon (1995). Measuring Stress
“Technically speaking, a stress reaction is a mental and physical response to an adverse situation that mobilizes the body’s emergency resources, the flight or fight mechanism, which floods the body with hormones that arose to meet the challenge. Unfortunately modern life continually triggers this response when we can neither fight or flee, which can lead to chronic heightening of blood pressure and muscle tension, irritability, anxiety, and depression-and a lowering of immune effectiveness”.
(Daniel Brown, 2003. Stress, Trauma and the Body, p. 89).
Stress enhances susceptibility to disease
Both psychosocial & biological stressors evoke the flight or fight response
Stress Disinhibition Theory People engage in a broad
range of dysfunctional behaviors as a result of stress
commonplace stressful events produce immunological alterations
chronic stressors have been linked to the longer-term down-regulation of immune function
immunological changes have negative consequences for health Lonely Person with a Kind Heart
Endocrine system facilitates communication between the
mind and body acts as an internal intelligence carrying
information that regulates the organism receptors for catecholamines (adrenaline)
in immune cells nerve fibers go "into virtually every organ
of the immune system and form direct contacts with the immune system cells“ (Ader, 1993).
The Defense/Defeat Model fight or flight immune system suppression Folkov (1993)
The central nervous system that regulates the ANS balance is called the central autonomic network (CAN). The CAN work with networks to regulate the following functions:
Executive Social, Affective Attentional Motivational
Autonomic, cognitive, and
affective function assist humans
maintaining balance in the face of environmental
challenges
Inhibitory or negative
processes or feedback
circuits that permit
behavior and redeploy
resources needed
elsewhere
When negative circuits are
compromised positive circuits
develop and result in hypervigalance. The symptoms can be devastating and if not ameliorated can develop into
permanent conditions
A common subcortico neural system regulates defensive behavior including autonomic, emotional and cognition
When prefrontal cortex is taken “offline” for whatever reason parasympathetic inhibitory action is withdrawn and relative sympathetic dominance associated with defensive occurs
This can be measured by assessing parasympathetic contribution to overall HRV
Growing evidence supports the use of HRV as a predictor of hypervigilance and inefficient allocation of attentional and cognitive resources (Thayer & Brosschot, 2005)
“Autonomic Imbalance and Decreased Parasympathetic Tone in particular may be the final common pathway linking negative affective states and dispositions, including the indirect effects via poor lifestyles, to numerous diseases and conditions as well as increased mortality, and it may also be implicated in psychopathological conditions”.
Low HRV is associated with the following conditions
cardiac symptoms of panic attack Poor attentional control Poor emotional regulation Behavior inflexibility

Depression (Thayer et al., 1998) Generalized anxiety disorders ( Thayer
et al, PTSD (Cohen et al., 1999) Cardiovascular morbidity and mortality Diabetes (Ziegler et al., 2001)
Immune deficiency and inflammation contributing to: Aging CVD Osteoporosis Arthritis Alzheimer’s Periodontal disease Certain types of cancers as well as
muscle decline increased frailty and disability
The overall objective of Heart Rate variability training is to decrease ANS hyperarousal and improve its balance.
Wounded Warriors learn to control ANS responses to stress producing stimuli such as thoughts, memories and images associated with combat.
Decreasing arousal and maintaining ANS balance for increasing lengths of time is the goal of training.
Once it was observed that alpha waves were dysfunctional in vulnerable populations protocols were developed to help people learn to train alpha and theta waves as a method of improving function.
Peniston and Kulkosky showed increased alpha and theta brainwave production resulted in normalized personality measures; and prolonged prevention of relapse in alcoholics. The protocol has also showed efficacy as an intervention in drug addiction, depression and PTSD.
The graded stress exposure training program used in this study is one month in duration and consist of a pre assessment, 16 biofeedback sessions (four per week) a post session evaluation and a 3 month follow up.
Each week participants will be exposed to increasing stress producing stimuli: 1. Stroop Color Word Test, Math Stressor; Talk Stressor/Everyday Events 2. Talk Stressor/ Combat Experiences; 3. Images and Sounds of Combat; 4. Virtual Baghdad or Afghanistan (virtual reality exposure).
Each biofeedback session consists of 5 minutes of baseline followed by 5 minutes of the weekly stressor, followed by 20 minutes of HRV and neurofeedback training, followed by 5 minutes of the stressor; followed by 20 minutes of HRV and neurofeedback and finally 5 minutes of recovery data.
Preliminary clinical data collected so far indicate decreases in ANS hyperarousal and increases in parasympathetic activity. Reports on PHQ-SF 36 indicated positive changes in physical symptoms, and decreases in depression panic attack and anxiety.

Dysfunction in ANS and CNS flexibility and balance are associated with symptoms of PTSD in combat veterans.
Methods that are designed to restore balance in these systems are needed to ameliorate these symptoms.
Biofeedback/Neurofeedback is a safe method to achieve these goals.
To create an awareness and understanding of the components of effective health improvement programs.
To explore the specific application of health applications in the treatment of PTSD, anxiety, and depression.
Define the treatment components of health improvement programs and their prescriptive parameters

Exercise and Body Awareness Nutrition Stress Management Mental Focus Relaxation-meditation- and other
antidotes to stress (recreation/physical activity)
The overall focus is on positive behavioral change and coping.
The first requirement necessary for change is that you want to change!
We are all in different STAGES with respect to multiple behaviors in our lives.
DEFINITIONS: Precontemplation
Someone in this stage probably has no intention of making change or adopting healthier habits.
Contemplation Someone in this stage realizes the importance of specific
changes. They may be thinking of making some behavioral changes in the next six months.
Preparation Someone in this stage is ready to make some behavioral
changes. They may already engage in some health behaviors some of the time but it is just not something they do regularly.
Action Someone in this stage has overcome all the obstacles and have
integrated behavioral changes but haven’t been doing it very long . They are doing it! (e.g., They are physically active on a regular basis– less than six months).
Maintenance Someone in this stage is has integrated the behaviors on
regular basis and has maintained these for more then six months.
PrecontemplationExample: Learn about all the benefits of being physically active. Start thinking about what being physically active could mean for you.
ContemplationExample: Remind yourself all the benefits you will get from being active. Picture yourself healthier and more energetic than ever before. Try to record your progress and improvements and make sure you have support from family and friends.
Preparation Set a start date. Tell everyone you know. Establish priorities. Make the change a high priority in your
life. Leave no room for excuses.
Stages of Change
ActionExample: Participate in activities that are not effected by the weather- join an exercise class or indoor sports league.Make physical activity a priority. Plan physical activity in your daily schedule. Make sure your family and friends know how important physical activity is to you.
MaintenanceMaintain your behaviors. Reinforce yourself.Examples: Try a new activity or sport.Vary your walking or cycling path.Change the music you walk to.Be active at different times during the day.
Stages of Change
Each level of the activity pyramid is important in helping you increase your physical activity level and overall health. Each day you should try to participate in a variety of physical activities. Remember not to limit yourself to one type of activity.
DEFINITIONS OF ACTIVITY PYRAMID LEVELS Aerobic Exercise: Aerobic exercise improves cardiovascular fitness and makes your heart and lungs stronger (3-5X/wk.). Recreational Activities: Recreational activities may also improve cardiovascular efficiency or more simply said will make your heart and lungs strong (2-3X/wk.). Leisure Activities: Leisure activities are low-level endurance activities. Flexibility and Strength: Flexibility activities help to increase and maintain muscle flexibility. Strength exercises can help improve muscle strength (2-5X/wk.). Sedentary: The top level of the pyramid signifies sedentary life. This is the smallest part of the pyramid and the activities here should take up the smallest amount of your leisure time.
Identify your personal activity levels based upon the activity pyramid.
Estimate the types of activities you do on an average week.
The purpose of this activity is to demonstrate the many inherent benefits of a recreational activity Think social, emotional, cognitive, physical, and
spiritual. Bingo: Swimming: Gardening: Arts & Crafts: Scuba Diving:

There is a need to identify automatic thoughts and patterns before intervention begins. One effective method is to have the
client/patient record a daily record of automatic thoughts ( A positive and negative thought diary!).
