Arista SD Plus TENS Unit
The Arista Strength Duration unit reduces pain by controlling each channel independently. This is a TENS unit that operates with Burst, Normal or Modulation modes. This is a dual channel unit, which allows you to use up to four electrodes at a time (two electrodes per channel). It comes with an AC/DC adaptor that plugs into the wall or it can work with a 9 volt battery.

Mode Selections
The SD TENS unit offers six settings on the mode switch:
- Burst Mode: This mode provides a series of seven pulses at a fixed rate of 80Hz. Bursts occur two times per second.
- Normal Mode: This mode provides standard stimulation for TENS.
- Modulation Modes: The four modulation modes are designed for the patient to obtain maximum comfort from TENS. Individual preferences can be met with these additional modes, improving patient compliance. Modulation of the TENS output parameters: width, rate and amplitude may prevent the nervous system from accommodating to the continuous mode of TENS, thus improving duration of pain relief.
- A. Strength-Duration Modulation (SD): Strength-Duration Modulation consists of alternating modulated amplitude and width so that one parameter is always decreasing while the other is increasing and vice versa. The amplitude decreases 60% from the amplitude control setting and returns to that setting. The width decreases 50% from the width control setting and returns to that setting. Total cycle time is six seconds.
- B. Modulated Width (MW): Pulse width decreases 48% (pulse width= 250 u sec.), 33% (pulse width= 180 u sec.) from the selected value, and then returns to the selected value. Total cycle time is six seconds.
- C. Modulated Rate (MR): Pulse rate decreases 63% (pulse rate= 150 Hz), 56% (pulse rate= 100 Hz) from the selected value, and then returns to the selected value. Total time is six seconds.
- D. Combination Modulation (CM): Combination modulation consists of alternating modulated width and modulated rate so that one parameter is always decreasing while the other is increasing and vice versa.
All values have 10% +/- tolerance
