QuadStar® II – Multi-Modality Stimulator

The QuadStar® II is a portable four channel digital TENS, NMES, and INF and device. The unique device with 3 waveforms, asymmetrical biphasic, symmetric biphasic, and pulsed sine waves can be programmed to deliver soothing therapies at a push of a button. There are 9 pre-programmed Fixed Sequences which enable the user to program 20 minutes of INF followed by 20 minutes of NMES 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 are shown on the screen to assist the user to program the RAMP on and off times. In addition, there is a patient compliance meter, timer, and comes with everything needed to begin your therapy sessions.

Patient Compliance Meter
The Patient Compliance Meter within this device when activated, locks in the program set by the physician preventing changes to ensure the prescribed treatment is used every time. When unlocked the system displays the amount of time the device has been used with the prescribed treatment. A timer allows the patient to use the device for a specified period.

CH1/CH3 (Carrier) Frequency: 4000 Hz
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

NMES Specs

NMES 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. Cycled:This mode delivers the desired stimulation through repeating cycles comprised of “timing options” (RAMP ON, RAMP OFF, ON TIME, OFF TIME and DELAY) in order to elicit repeated muscle contractions and rest periods. In the CYCLED mode all Channels 1, 2, 3, and 4 output then rest waiting for the next cycle occurrence. Reciprocal:This mode delivers the desired stimulation through repeating cycles comprised of “timing options” (RAMP ON, RAMP OFF, ON TIME, OFF TIME and DELAY) in order to elicit repeated muscle contractions and rest periods.In the RECIPROCAL mode Channel 1 and 2 cycles alternate with Channel 3 and 4 cycles.
