Biofeedback

Question 1

what is biofeedback

Answer 1

The process of detecting physiological activity in the body and converting that activity into visual and/or auditory cues that the patient can use

Question 2

how is biofeedback measured

Answer 2

The scale on a biofeedback unit may use the number of microvolts, a simple 0-to-10 scale, or a bar graph or other visual representation as the measure

Question 3

what does the “two active electrodes” measure

Answer 3

the amount of electrical activity within the muscle

Question 4

what is the thrid electrode used for and what is refered to as

Answer 4

it’s called the refernece electrode and used to filter out nonmeaningful electrical activity

Question 5

what is the neuromuscular effect of biofeedback

Answer 5

assist in reopening a neural loop that sends efferent signals to the appropriate muscles

Question 6

how does biofeedback help with pain reduction

Answer 6

• Re-educating muscle and reducing atrophy helps to restore normal biomechanics
• Decreasing muscle spasm reduces the amount of mechanical pressure placed on nociceptors

Question 7

what are the contraindications for biofeedback

Answer 7

• Conditions where muscle tension or joint motion would cause further injury
• Unstable fractures
• Joint structure injury

Question 8

true or false

Primary concern relates to the unit’s accuracy in detecting the muscle’s raw signal

Answer 8

true

Question 9

what is the instrument called which allows fine adjustments on the threshold required to obtain feedback

Answer 9

tuner

Question 10

Question 11

what are methods to help facilitate muscle contractions

Answer 11
