Biofeedback

Development of Biofeedback

• Instrumental conditioning of the autonomic nervous system (1967-1969 Miller)

• Psychophysiology (Shapira 1965)

• 1969 – Biofeedback Research Society

• 1988 – Association of Applied Psychophysiology and Biofeedback –www.aapb.org

Biofeedback is a technique that enables an individual to learn how to change

physiological activity for the purposes of improving health and performance

(Gilbert & Moss, 2003; Schwartz & Andrasik, 2003)

Physiological activity7

• Muscle Tension – ElektroMyoGram/EMG

• Heart Rate – EKG/Pulse

• Respiration (rate)

• Sweating – Skin Conductance

• Peripheral Temperature

• Brain Waves – EEG

• And more: Force, HEG, Oxygen, etc.

Biofeedback8

• Important:

– Motivated Client

– High quality instruments thatreliably measure what you would like to measure (validity)

– Good therapist.

Active involvement of client = Training!

Biofeedback Instruments

Biofeedback instruments are used to visualize physiological processes, increase awareness of them and to gain voluntary control over

body and mind.

Learning principle:• Operant conditioning: creating new habits by (positive) reinforcement (Skinner)

Set-up 12

Therapist Client

General indications for Biofeedback

• Showing psychophysiological interaction and increasing knowledge of biopsychosocial model

• Stressmanagement/relaxation

Specific indications for Biofeedback

• Tension Headache, Migraine• Chronic pain, back pain• Essential hypertension • ADHD• Anxiety• Insomnia • PTSD• Performance enhancement – sports/management • Constipation• Substance abuse – drugs/alcohol• Rehabilitation• Incontinence• …….

“Evidence-Based Practic in Biofeedback and Neurofeedback”. Carolyn Yucha Ph.D; Doil Montgomery, Ph. D. American Association of Apllied Psychophysiology & Biofeedback (AAPB. www.aapb.org)”

Goals of Biofeedback

• Improvement of perception of physiological processes (Interoception)

• Improvement of controlling these processes and improvement of believe of control.

• Identification of factors that influence physiological processes

Steps in Biofeedback

• Awareness of physiological processes

• Control – changing Behaviour

• Generalization - Transfer to daily life.

Generally about 10 sessions in Biofeedback/30-40 in Neurofeedback

Stress - Biopsychosocial model17

Stress Stress

Stress

WHO 1948: “Health is a state of complete

physical, mental and social well-being and

not merely the absence of disease or infirmity”

Environment18

Stress and our brain19

Stress/Thoughts can lead to physical/physiologicaleffects that can be similar to physical excercise

(body/mind interaction)

Psychosomatic Romans about 2000 years ago “Mens sana in corpero sano” – A healthy mind in a healthy body.

(Autonomic) Nervous System 20

The nervous system

Central nervous system (CNS)

Brain Spinal cord

Peripheral nervous system (PNS)

Somatic nervous system

Controls voluntary movement

Peripheral nervous system

Controls involuntary responses

Sympathic

Fight or flight

Parasympathic

Rest and digest

Sympathetic (Gas – Fight/Flight) Parasympathetic (Brake - Relaxation)

Stress - Survival mechanism22

Chronic Stress 23

Effect stress fully normal, chronic stress can lead to disbalances which in its turn can lead to different (or have effect on) conditions like chronic tension

headache, anxiety, hypertension, etc.

Stress related parameters

What happens in stress?25

• Muscle Tension

• Skin Conductance

• Heart Rate

• Temperature

• Respiration rate

What happens in stress?26

• Muscle Tension

• Skin Conductance

• Heart Rate

• Temperature

• Respiration rate

A core principle that Biofeedback uses is physiological activation versus relaxation

Activation versus relaxation

(Ab-)normal stress responses28

Normal stress response

Abnormal stress response

Stress profiling

• Set-up

– Baseline (reading in silence)

– Stressors

• Alphabet backwards

• Think of as much animals with an “R”

• Deduct 7 from 1081, etc..

– Relaxation

• Offers valuable information for client and therapist (or athlete!)

Performance enhancement - Sports

Peak performance does not depend on physical ability alone.

Where physiology meet psychology

• Difference can be made by mental focus of an athlete, especially under high pressure.

• Athletes have to be able to relax and control their mental state.

Psychology Physiology

Performance and Bio- Neurofeedback

Biofeedback and Neurofeedback can be helpful for athletes to

detect shift in mental state while resting, practicing, or participating in high stress

and competitive environment.

Performance and Bio- Neurofeedback

• Getting insight in psychophysiology (biofeedback) in order to:

– Improve emotional self-regulation (biofeedback). More contol over energy levels.

– Improve focus (bio- and neurofeedback)

• Can help facilitate in recovery from injury.

Use and training techniques

• Examples

– Complementary to existing (relaxaton) techniques

– Visualization: reduce stress, sustain focus by directing attention of the athlete to a specific aspect of the performance.

– Simulators: replicate physiological sensations and control them, learning to better anticipate

– Insights in physiology before, during and after performance

Use and training techniques36

Training Mind-Body functions

Demo measurement

Case Headache40

• Intake

– Headaches since 1 year, originated from stressfull period.

– Less stress is less complaints, symptoms never completely gone.

Skin Conductance

Temperature

Breathing

Heart rate

Left shoulder

Right shoulder

42 Left Trapezius1,9 uV

Frontalis –forehead 2,1 uV

Right Trapezius2.2 uV

Case Headache43

• Results– EMG and hand temperature go well– Skin Conductance high and reactive– Breathing rate high (18 times a minute)– Too little interaction between heart rate and

breathing rate

• Client– Also thinks muscle tension is not a problem and

recognizes warm (sweaty) hands– Skin conductance: always busy, sees and hears

everything– Didn’t know about interaction breathing/heart rate

Case Headache44

• Protocol– Headache probably not related to muscle tension.

High skin conductance remarkable. Client continuously reacting which can lead to overload, which results in headache

– Idea to try biofeedback to lower skin conductance and normalize breathing

• Home work– Slower breathing

– Meditation – bodyscan

Case Headache45

• Session 2

– Home work done in car and at home, could not do it a work

– Bodyscan very hard

• New measurement

– With breathing based on feeling

– SC little less and little less reactive

Skin Conductance

Temperature

Breathing

Heart rate

Left shoulder

Right shoulder

Case Headache47

• Training

– Puzzle: stops when skin

conductance rises

– Bargraph: moves too much

Case Headache48

• Training

– Bargraph removed:

Lowering SC, still quite reactive

– Slow breathing at same time

Case Headache49

• Results

– Learned to control and lower skin conductance within 4 session

– Takes more rest, especially when too many thing are going on

– Strong reduction headache to almost none

– Last appointment cancelled due to absence of complaints

Case Fatigue 50

• Intake

– Mrs B, 46 years old

– Fatigued, agitated and emotionally unstable

– Feeling gest worse at situations she does not feel at ease, feeling of unwelcomeness and no being accepted

Temperature

Breathing

Heart rate

Left shoulder

Right shoulder

Case Fatigue52

• Results

– Fast and shallow breathing

– Cold hands with temperature decreasing during the test.

– Unconcious tensing shoulder.

– Cold hands may indicate that client approaches the world with suspision, which is indeed the case. (insecurity, anxious). Shallow breathing may be explained by this as well (pattern associated with anxiety)

Case Fatigue53

• Protocol– Breathing training with pacer

– Home excercises.

• Results– Noticed that other accepted her, being herself.

– Comfortable in groups

– Another job, which suited better

– After a while fatigue diminished

– Last stress stress warm hand and normal responses

Neurofeedback

Neurofeedback is a speciality field within Biofeedback where the goal is to training

people to gain control over electro-physiological activity in the human brain (EEG

– ElectroEncephalogram)

(Gilbert & Moss, 2003; Schwartz & Andrasik, 2003)

Development of EEG/Neurofeedback81

Neurofeedback training approaches

- Frequency band training

* Standard protocol (Cz, C3, C4)

* QEEG guided Neurofeedback

- Z-score training

- Slow Cortical Potentials neurofeedback

- HEG neurofeedback

Neurofeedback sessions

• 30/40 session 1-2 times a week

– Often combined with BFB to reduce # sessions

– Different phases:

• Learning/Automisation;– 1-10 sessions; client feels tired in beginning, after around 10

sessions getting feeling of control and keeping the desired state

• Stabilising: – 11-20: learned condition is stabilised and can be controlled for

longer periods. Often more feeling of focus. Often feeling ofbteer sleeps, faster recovery.

• Performance enhacement phase– 21-30: Increasing learned control even more.

QEEG117

QEEG is Quantified EEG. Nuwer, 1997: The mathematical processing of digitally recorded EEG in order to highlight specific waveform components, transform the EEG into a format or domain that provides relevant information, or associate numerical results with the EEG data for subsequent review or comparison.” (Nuwer, 1997)

One of the simplest forms is spectral analysis 1 channel quantified EEG

QEEG118

- Often linked to 21 channel full cap EEG.

- Clinically: comparing (standard deviations) to a QEEG database like:

• Neuroguide• Loreta

-Prognostic tool.
