OVERVIEW
Intensity (Electrotherapy)
- Intensity is the output of electrotherapy distributed by the unit to the patient. Depending on the waveform,
intensity is measured in milliamps (mA) or volts (V).
Intensity (Ultrasound)
– Ultrasound power delivered to the patient expressed in total power as watts (W) or in terms of the sound head’s
effective radiating area, watts per centimeter squared (W/cm
2
).
LCD-
The LCD (Liquid Crystal Display) allows the user to view and monitor the information displayed during ultrasound therapy. The
following information is displayed on the LCD: Frequency, Duty Cycle, Power and Treatment Time.
Lead Zirconate Titanate
– A synthetic crystal used to create the ultrasound beam by vibrating 1000000 (1 MHz) or 3300000 (3.3 MHz)
times per second. This type of crystal is both durable and efficient in its functions.
Leadwires
- The leadwires consist of the main plugs that are connected to the unit, and 4 leads (2 black and 2 red) that connect to
electrodes.
Medium Frequency Current
- These are the currents used by Interferential, Premodulated, and Russian waveforms that is higher than
1000 Hz, but lower than 5000 Hz.
Operating Channels
- Operating Channels are the paths by which the electrotherapy is distributed from the unit to the patient. The unit
provides two channels of electrical stimulation.
Phase Duration
- This is the time in which the current flows in one direction only. Phase duration is the determined period of time
elapsing from the beginning to the end of one phase, usually expressed in microseconds (μsec) or milliseconds (ms).
Polarity
- Polarity refers to the charge of an individual lead: positive or negative.
Polarity Reversal
- This is a feature available on the unit in which the polarity changes at a determined time.
Power
– A measure of the intensity of the ultrasound delivered to the patient. The unit of measure is watts (W).
Protocol
– A group of parameters (e.g., Frequency, Duty Cycle, etc.) unique to a form of therapy (i.e., electrotherapy or ultrasound).
Pulse Duration
– Refers to the amount of time the ultrasound is being delivered in the pulsed mode. For example, in the 20% duty cycle
mode, the ultrasound is delivered for 2 msec and off for 8 msec (at 100 Hz) throughout the treatment period.
Pulse Frequency
– The pulse frequency is the number of pulses per second and is expressed in hertz. The available pulse frequencies for
ultrasound therapy is 100 Hz.
