Biofeedback Flashcards
1
Q
Biofeedback
A
- instantaneous return of info regarding muscle function we may be unaware of
- facilitates immediate volitional control of the muscle activity
2
Q
Biofeedback Mechanism
A
- surface electrodes placed over muscles motor point
- muscles electrical signal detected by electrode and reported to feedback unit
- feedback unit converts electrical signal into audio and visual signals for patient to view
3
Q
Biofeedback Indications
A
- Muscle Strenghtening
- Muscle re-education
- decreasing antagonistic muscle activity
- decreasing muscle spasms
- headache/stress/relaxation
- urinary incontinence, pelvic floor dysfunction
4
Q
Benefits of Biofeedback
A
- muscular re-education
- muscle strenghtening
- decreased antagonistic muscle activity/spasm
- increased ROM
5
Q
Contraindications
A
- condition where muscle contraction or monitored physiological function is contraindicated
- if using stim combined with emg biofeedback, consider all stim contraindications
6
Q
Surface Electrodes Types
A
- metal w/ ocnductive gel
- fixed inter-electrode distance embedded in pre-amplifier
- disposable adhesive
7
Q
Surface Electrode Advantages
A
- ease of application/ reproducible
- patient comfort
8
Q
Surface Electrode Disadvantages
A
- muscle cross talk - detects signals from more than one muscle group
- surface muscles only
9
Q
Fine Wire Electrode
A
- needle electrode containing insulated wire with bared distal ends
- needle inserted into muscle, needle withdrawn, wire remains
10
Q
Fine Wire Electrode Advantages
A
- smaller/ deeper muscles
- increased specificity
11
Q
Fine Wire Electrode Disadvantages
A
- invasive/ patient discomfort
- less repeatable
- require muscle stimulation to confirm location
12
Q
Placement of Electrodes
A
electrodes closer together yield smaller signal with more precision
- electrodes further apart yield larger signal yet possibility for detecting more than one muscle
- apply electrode over the motor unit
