Electric Modalities Flashcards
It is the application of electrical stimulation to facilitate a desired therapeutic response
Clinical Electrotherapy
High Frequency Current: Frequency
> 100,000Hz
High Frequency Current : WL
<10mm
High Frequency Current: Clinical effects
Heating
Middle Frequency Current: Frequency
1000-100,000Hz
Middle Frequency Current : WL
> 10mm
Middle Frequency Current: Clinical effects
Pain modulation
Low Frequency Current: Frequency
<1000Hz
Low Frequency Current: Wl
> 10MM
Low Frequency Current: Clinical effects
Nerve and muscle
stimulation
- Driving force that moves electrons or pushes charge
Voltage
Materials in which ions or electrons move freely
Conductors
materials in which charged particles are not free to move or do not move
easily
Insulators
Unresisted movement of ions or electrons in a conductor in response to a voltage force
Current
Frequency-dependent form of resistance
Impedance
- Opposition to the flow of alternating current
Impedance
device that serves as the interface and link between an
electrical stimulation (ES) device and the patient
Electrodes
two elements of electrodes
- electrode itself
- conducting coupling medium
Use of two
electrodes: (1)
active electrode (2)
inactive/dispersive
Monopolar
Use of two active electrodes
Bipolar
- application of two or
more electrodes from two
separate circuits.
Quadripolar
to activate skeletal muscle
for improving muscle performance or strengthening, to attenuate or alleviate pain, to improve blood flow,
to decrease or control edema, or to facilitate tissue healing.
Electric Stimulation
Activation of skeletal muscle with the primary goal of: strengthening.
Neuromuscular Electrical Stimulation
Activation of skeletal muscle with the primary goal of: reeducation and retraining for
functional use and ADL performance.
Functional Electric Stimulation
Activation of skeletal muscle with the primary goal of facilitating muscle contraction and delaying atrophy
Electric Muscle Stimulation
Activation of sensory level and motor level (but not muscle fiber level) with the primary goal of pain modulation
Transcutaneous Electrical Muscle Stimulation
Another name for uninterrupted/continuous direct current
High Voltage Galvanic Stimulation for Wound and Tissue Repair
is a technique which uses direct current to facilitate the movement of ions (drugs/medicine) across the skin.
Iontophoresis
