Final: Biofeedback Flashcards
___ is the recording of electrical activity generated in a muscle
EMG
An _______ is a graphic representation of electrical currents associated with muscle action
electromyogram
EMGs have (low/high) sensitivity to low levels of muscle activity
high
What is the order of an EMG signal
EMG signal initiated Raw Amplified Rectified Smoothed Signal processed back to user
What type of electrodes can be used with biofeedback
needles or skin electrodes
______ is the nearly instantaneous return of information to a person about physiologic functions she or he may not otherwise be aware of
biofeedback
Biofeedback provides information about ______ or ______ processes that can be acted on for improved function and performance
physiological and biomechanical
True or False
Biofeedback requires user action
true
True or False:
Just like other physical agents, biofeedback results from transfer of energy to targeted area
False, it does not result from transfer of energy
What are the two types of biofeedback
direct and transformed
(direct/transformed) biofeedback is an accurate, numerical value of bioprocesses
direct
What is an example of direct biofeedback
heart rate monitor
(direct/transformed) biofeedback is a representative signal of muscular electrical activity
transformed
What is an example of transformed biofeedback
EMG
What are the physiological effects of biofeedback
provides feedback for volitional alteration activity based on myoelectrical activity
What are the primary neurophysiological mechanisms of biofeedback
neuromuscular facilitation
inhibition
coordination
Neuromuscular inhibition is an (increase/decrease) tone due to activation of fewer or smaller motor units
decrease
In regards to neuromuscular inhibition, is there an increase or decrease of afferent inhibition of aberrant efferent signals
increase
What are three indications of using neuromuscular inhibition techniques
relaxation techniques
postural training
decrease excessive muscle tone
What are 8 clinical applications of using EMG biofeedback
muscle reeducation relaxation of muscle guarding hemiplegia quadriceps strengthening pelvic floor disorders chronic pain disorders TMJ disorders
In regards to using biofeedback for muscle reeducation, is the sensitivity supposed to be high or low
low
In regards to using biofeedback for muscle guarding, is the sensitivity supposed to be high or low
high, make sure the noise is turned off
