8. Step to Set Parameter
The parameter of a treatment course can be adjusted according to the following
steps. Press “Select” button to select the function you wish to set.
a. Turn on the intensity
After the electrodes are placed firmly on skin and the lead wires are plugged in the
socket of device, turn the on/off control clockwise. The menu will appear on LCD.
Notice the indication of power and function on the LCD.
b. Set Contraction Time
The contraction time controls the time of stimulation. By pressing parameter
controls, the contraction time can be pre-set. The range is adjustable from 1
second to 30 seconds.
c. Set Relaxation Time
The relaxation time determines the time of relaxation. The stimulation ceases at
setting. Relaxation time of both channels is changed by pressing the parameter
controls. The range of it is adjustable from 1 second to 45 seconds.
d. Set Ramp Time
This ramp time controls the time of output current that increases from 0 to the
setting level and from the setting value to 0. When the ramp time is set, each
contraction may be ramped in order that signals come on and come off gradually
and smoothly. The ramp time is adjustable from 1 second to 8 seconds by pressing
the parameter controls.
Note: Gradual “Ramp” time
The stimulator special circuitry is designed so the electrical impulses gradually build
to a peak and then level off. This “ramped” pulse produces a gradual muscle
contraction emulating natural muscle movement. It can also prevent spastic
patients from reacting adversely. The duration and intensity of the electrical pulses
are predetermined by the clinician.
e. Set Pulse Rate
The pulse rate determines how many electrical impulses are applied through the
skin each second. By pressing the parameter controls, the number of current
impulses per second (Hz) for both channels can be continually adjusted.
The pulse rate is adjustable from 1 Hz to 150 Hz.
f. Set pulse Width
The pulse width determines the length of time. Each electrical signal is
applied through the skin, which controls the strength and sensation of the
stimulation.The pulse width is adjustable from 50 to 250 ㎲. Press the buttons
until the desired value is reached.
