A
The amount of time from the initial nonzero charge to the return to a zero charge, including the intrapulse interval.
Pulse duration
A circuit in which the current has only one path to follow.
Not at sensory level that is perceptible.
Subsensory level
when two different frequencies interfere with each other and become a different frequency.
Interferential Stimulation
A complete pathway that allows electrons to flow to and from the electrical source.
Closed circuit
A negatively charged atomic particle
Electrons
A pulsed current possessing two phases, each of which occurs on opposite sides of the electrical baseline. The bidirectional flow of electrons that is marked by discrete periods of noncurrent flow.
Biphasic pulsed current flow
time between the end of one pulse and the start of the next pulse.
Interpulse interval
High enough to activate motor nerves. VISIBLE contraction of muscles.
What is the best method for reducing edema?
ELEVATION
A flow of electrons is marked by discrete periods of non-electron flow.
Pulsed current
A law stating that opposite charges attract and like charges repel each other.
Coulomb's Law
Direct current modalities deliver a unidirectional, uninterrupted current flow within the tolerance of the patient and without the destruction of tissue.
Medical Galvanism or Galvanic Stimulation
An incomplete pathway that does not allow electrons to flow to or from the electrical source.
Open circuit
What is HVPS used for?
muscle re-education, nerve stimulation, reduction of edema, wound healing, pain control.
The number of cycles per second.
Hertz
The period within a discrete pulse when the current is not flowing. The duration of the intrapulse interval cannot exceed the duration of the interpulse interval
Intrapulse interval
This level stimulates pain fibers, has a short phase duration, and low pulse rate.
Noxious level
What are the factors that determine resistance?
1) material
2) length of circuit
3) cross-section
4) temperature
Which intermittent compression device is PRIMARILY used for acute or chronic pain management?
TENS: Transcutaneous Electrical Nerve Stimulation
The number OF TIMES an event occurs in 1 second; measured in hertz (cycles per second) or pulses per second
Frequency
Providing care that falls below the minimum standard.
Negligence
The effects of electrical stimulation result of depolarizing sensory, motor or pain nerve fibers.
Central Electrical Stimulation
When a blood clot forms in one or more of the deep veins in the body.
Deep vein thrombosis
This level has a longer phase duration and intensity level that causes muscle fibers to depolarize.
Muscle fiber level
