Waveform?
IS THE CONSISTENT PATTERN OF A CURRENT MEASURE ON A OSCILLOSCOPE.
A unit of measure or electrical power or electromotive force?
VOLT
The minimal intensity used with a long current duration that produces a small muscle contraction?
RHEOBASE
Resistance?
DESCRIBES THE ABILITY OF A MATERIAL TO OPPOSE THE FLOW OF IONS THROUGH IT
Refers to the number of seconds it takes for the amplitude to gradually increase or decrease to the maximum value set by amplitude control?
RAMP
The amount of time that it takes to complete all phases of a single pulse?
PULSE DURATION
Pulse duration is often labeled as?
PULSE WIDTH
One individual waveform?
PULSE
Has gained one or more electrons and posses a negative charge?
NEGATIVE ION
Describes a pulse that has either a positive or negative polarity and moves in only one direction from a zero baseline and returns to the baseline within a predetermined amount of time?
MONOPHASIC
Low-volt current?
LOW-VOLT CURRENT IS CHARACTERIZED BY A WAVEFORM OF LESS THAN 150 VOLTS AND IS USED FOR NEUROMUSCULAR STIMULATION
Ion?
A POSITIVELY OR NEGATIVELY CHARGED ATOM
The period of time of electrical inactivity between each pulse, usually expressed in microseconds or milliseconds?
INTERPULSE INTERVAL
Is the property of a substance that provides resistance to the flow of current by offering an alternate current?
IMPEDANCE
Is intermittent and is used for deeper tissue penetration?
HIGH-VOLT CURRENT
High-volt current?
IS CHARACTERIZED BY A WAVEFORM GREATER THAN 150 VOLTS WITH A SHORT PULSE DURATION.
Determines the number of pulses delivered through each channel per second?
FREQUENCY
Frequency controls are often rated as?
RATE
Electrical impedance?
IS THE RESISTANCE OF A TISSUE TO ELECTRICAL CURRENT
Duty cycle?
REFERS TO THE PERCENTAGE OF TIME THAT ELECTRICAL CURRENT IS ON IN RELATION TO THE ENTIRE TREATMENT TIME.
Refers to the constant unidirectional flow of ions. The direction of the current is dependent on polarity?
DIRECT CURRENT (MONOPHASIC OR GALVANIC)
Direct current is AKA?
*MONOPHASIC
*GALVANIC
Current?
DESCRIBES THE FLOW OF ELECTRONS FROM ONE PLACE TO ANOTHER
Describes the ease at which a particular material will allow current to flow (mho)?
CONDUCTANCE
Chronaxie?
A TESTING PROCEDURE USED TO MEASURE THE AMOUNT OF TIME REQUIRED TO PRODUCE A SMALL MUSCLE CONTRACTION AT A PARTICULAR INTENSITY?
Used during direct current electrotherapy is the negatively charged electrode that attracts positive ions?
CATHODE
A property of an insulator that allows for the storage of energy when the opposing surfaces of the insulator have an electrical potential difference?
CAPACITANCE
An interrupted group of pulses that are delivered in a finite series and predetermined frequency?
BURST
What are the different forms of biphasic pulse?
*SYMMETRICAL
*ASYMMETRICAL
*BALANCED
*UNBALANCED
Biphasic?
DESCRIBES A PULSE THAT MOVES IN ONE DIRECTION, RETURNS TO BASELINE, THEN IN THE OTHER DIRECTION AND BACK TO BASELINE AGAIN WITHIN A PREDETERMINED AMOUNT OF TIME.
Used during direct current electrotherapy is the positively charged electrode that attracts negative ions?
ANODE
Amplitude controls are often labeled as?
*INTENSITY
*VOLTAGE
Ampere?
A UNIT OF MEASURE USED TO DESCRIBE THE RATE OF CURRENT
Allows for the constant change in flow of ions?
ALTERNATING CURRENT (BIPHASIC CURRENT)
