The QuadStar II is a portable four channel digital NMS, INF and TENS device. The unique device with 3 waveforms, symmetric biphasic, pulsed sine and asymmetrical biphasic can be programmed to deliver NMS, INF or TENS therapy.

There are 9 preprogrammed Fixed Sequences which enable the user to program 20 minutes of INF followed by 20 minutes of NMS therapy and ending with 20 minutes of TENS therapy. A Programmable Sequence allows the user to customize the therapy and times. A graphic representation of the timing parameters is shown on the screen to assist the user to program the on/off ramps and on/off times.

In addition there is a patient lock system when activated prevents the patient from changing any parameters. When the lock is turned off, a patient compliance meter is displayed.

The device comes with a Wall Adaptor.

  • CH2/CH4 Frequency: 4001-4150 Hz
  • Beat Frequency: 1-150 Hz
    CH1/CH2 are an Interferential Pair
    CH1: Fixed Frequency (4000 Hz)
    CH2: Adjustable 4001-4150 Hz
    CH3/CH4 are an Interferential Pair
    CH3: Fixed Frequency (4000 Hz)

  • NMS Specs

  • Waveform: Symmetrical, biphasic, square Asymmetrical, biphasic, square
  • Pulse Rate: Adjustable 1-120 Hz peak to peak
  • Pulse Width: Adjustable 50-400 uS
  • On Ramp: 0-10 seconds
  • On Time: 0-99 seconds
  • Off Ramp: 0-10 seconds
  • Off Time: 0-99 seconds
  • Modes: Constant Use the Constant Mode or a Pulse Rate greater than 60 Hz. for the relaxation of muscle spasms only. Use of continuous stimulation and/or rates above the normal physiological range (e.g., greater than 60 Hz) could lead to rapid onset of muscle fatigue, making the device less effective in producing repeated forceful muscle contractions.

    4 of 5 One of the Electrodes/Leadwires is not working wel July 16, 2014
    Reviewer: JINPING ZHANG from ORILLIA, ON Canada  
    One of the Electrodes/Leadwires is not working well sometime.

    The Intensity looks like not from 0 - 120 mA,I feel It is from 50-120mA .to hot!
