Lewis: Stress Biofeedback Flashcards
What is the mechanism of stress?
Increased HPA, SNS, altered behaviors
What is biofeedback?
A group of therapeutic procedures that
uses electronic or electromechanical instruments to accurately measure, process, and feedback, to persons & their therapists,
Information with educational & reinforcing properties
about their neuromuscular and autonomic activity, both normal & abnormal,
In the form of analog or binary, auditory, and/or visual feedback signals.
What are biofeedback modalities?
Physiological changes result in symptom changes
Cognitive changes lead to symptom changes
Placebo/nonspecific effects account for symptom changes
Freeforward processes account for symptom changes
What evidence supports the effectiveness of biofeedback therapy?
Real time feedback of physiological change to assist in operant conditioning and patient education
Developing psychophysiological self regulation is often unlearnable without this information
Provision of safe, effective, and cost efficient non-pharmacological therapies
Define heart rate variability.
A measure of the autonomic nervous system that assesses sympathetic and parasympathetic responses (relaxation and stress response) by recording inter-beat intervals
shown to predict CVD, diabetes and HTN
What stress hormones are associated with HPA stress pathways? SAM stress pathways?
HPA- EPI and NE
SAM- CRH, ACTH, cortisol
What are the two branches of the nervous system and what physiological functions are they associated with?
Sympathetic- fight or flight
Parasympathetic- rest and digest
What are the three HRV frequencies and what do they represent?
VLF (very low frequency) .005-.05–> sympathetic activation (increase in worry)
LF (low frequency) .05-.15–> parasympathetic and sympathetic balance (meditation increases)
HF (high frequency) .15-.40–> parasympathetic activation (relaxation response)
What type of educational intervention is biofeedback?
operant conditioning
