Senior Solutions™ Therapy System
4 SPECIFICATIONS
E. VMS™- Figure 4.6
VMS is a symmetrical biphasic waveform with a 100 μsec interphase
interval. Because the pulse is relatively short, the waveform has a low
skin load, making it suitable for applications requiring high intensities,
such as in muscle strengthening protocols.
Output Mode………………………………………Electrodes
Output Intensity………………………………………0-200 mA
Channel Mode……………………Single, Reciprocal, Co-Contract
Phase Duration………………………………………20-400 μsec
Mode Selection…………………………………………CC or CV*
Anti-Fatigue……………………………………………Off or On
Set Intensity…Individual Channel Intensity Setting in Reciprocal and
…………………………………………………Co-Contract modes
Cycle Time…………Continuous, 5/5, 4/12, 10/10, 10/20, 10/30, 10/50
Frequency…………………………………………………1-200 pps
Ramp………………………………0.5 sec, 1 sec, 2 sec, and 5 sec

F. IFC (Interferential) Premodulated (2p)- Figure
4.7
Premodulated Current is a medium frequency waveform.
Current comes out of one channel (two electrodes). The
current intensity is modulated: it increases and decreases
at a regular frequency (the Amplitude Modulation
Frequency).
Output Mode……………………………………Electrodes

Sweep Low Beat Frequency………………………1-199 Hz
Sweep High Beat Frequency…………………… 2-200 Hz
Cycle Time…Continuous, 5/5, 4/12, 10/10, 10/20, 10/30, 10/50
Mode Selection ……………………………………CC or CV*
Treatment Time………………………………… 1-60 Min
Available on Channel………………… 1 & 2, 3 & 4 Option
