C. TENS- Symmetrical Biphasic- Figure 4.4
The Symmetrical Biphasic waveform has a short pulse duration
and is capable of strong stimulation of nerve fibers in the skin
and in muscle. This waveform is often used in portable muscle
stimulation units, and some TENS devices. Because of its short
pulse duration, the patient typically tolerates the current well,
even at relatively high intensities.
Output Mode……………………………Electrodes
Output Intensity……………………………0-80 mA
Phase Duration……………Adjustable 20-1000 μsec
Frequency…………………………………1-250 Hz
Mode Selection…………………………… CC or CV*
Burst Frequency……………………………0-10 bps
Frequency Modulation……………………0-250 Hz
Amplitude ModulationOff, 40%, 60%, 80%, and 100%
Treatment Time……………………………1-60 min
D. High Voltage Pulsed Current (HVPC)-
Figure 4.5
The High Voltage Pulsed Current (HVPC) has a very
brief pulse duration characterized by two distinct peaks
delivered at high voltage. The waveform is monophasic
(current flows in one direction only). The high voltage
causes a decreased skin resistance making the current
comfortable and easy to tolerate.
Output Mode…………………………Electrodes or Probe
Output Intensity……………………………………0-500 V
Polarity……………………………… Positive or Negative
Ramp……………………………0.5 sec, 1 sec, 2 sec, 5 sec
Display………………………………Peak Current or Volts
Sweep…… Continuous, 80/120 pps, 1/120 pps, 1/10 pps
Frequency…………………………………… 10-120 pps
Cycle Time…5/5, 4/12, 10/10, 10/20, 10/30, 10/50, Continuous
Treatment Time………………………………… 1-60 Min
Available on Channels…………………1 & 2, 3 & 4 Option
