I/t curve
It is recommended to use the results obtained by determining I/t curve to create a program of
electrostimulation of flaccid muscles treatment program that will be executed exclusively with the
PhysioGo.Lite Electro unit.
Step Description
1.
Switch the unit on.
2.
Choose the tab 1, mode
Confirm by the button or once again press
the selected field.
3.
If the unit is in manual mode, press
4.
Using keys or by touch set the position of I/t curve. Confirm by pressing the selected field
once again.
5.
Prepare the patient for the treatment according to indications in point 7.1. It is recommended to use
the point electrode (cathode, black plug) as an active electrode.
6.
Press key
or button . The unit is in stimulation mode.
7.
Using the keys or buttons , increase the output current for the pulse duration of
1000 ms until reaching value, at which minimum muscle contraction is observed. The current value
is automatically applied to the chart.
The pulses appear at 2 seconds intervals.
8.
Using the button , move one position to the
right to the value under 700 ms pulse duration.
Again, set the current at such a value at which
minimum muscle contraction occurs, then mark it
on the diagram (setting starts with value
measured for the previous pulse width time, you
can reduce the current and start your observation
from zero value of the output current). Repeat
the procedure for all rectangular and triangular
pulse time values.
9.
Upon completion of stimulation, press the
button , the unit will automatically display:
• rheobase, chronaxie, accommodation
threshold value,
• accommodation factor value along with
commentary and visual evaluation on the
scale,
• quotient accommodation value with
commentary and visual evaluation on the
scale.
10.
Press to see again the graph. Press to save the curve. Enter the name and press
