The Quattro 2.5 Clinical Electrotherapy Unit

quattro The Quattro 2.5 clinical electrotherapy unit is named after the Italian word for ‘four’ not only because it has four channels of electrical stimulation output, but also because it features four different waveforms: Interferential, Russian Stim, TENS, and EMS.

Features

  • Four channels of electrical stimulation output.
  • Easy-to-Read Large LCD display.
  • Exact dial performance.
  • 2 Separate Programmable Timer.
  • Waveforms include: TENS, EMS, Premodulated (2-Pole Interf.) and Interferential (4-Pole Interf.), and Medium Frequency (Russian).
  • 10-presets per waveform.
  • User-defined memory positions for user protocols.
  • Designed for tabletop, therapy cart, or mobile use.
  • Includes eight sets of electrodes, eight sets of rubber electrodes with sponges, eight straps, four sets of lead wires and a user manual.
  • User-friendly design.
  • Portable.

Pros

The Quattro 2.5 clinical electrotherapy unit can be used to relax muscle spasms, prevent disease atrophy, promote blood circulation, reeducate muscles, maintain or improve range-of-motion, relieve symptoms of chronic pain, and manage post-traumatic acute pain and post-operative pain. Additionally, it can be used to treat two different patients or two different areas of the same patient at the same time.

Cons

Electrical stimulation may cause skin irritation, inflammation, and electrode burns underneath the electrodes. Patients may experience headache during or following stimulation near the eyes, head, or face. Electrotherapy has no curative value and is not effective against pain of central origin. It does not replace pain medications or other pain management therapies. This product is not to be used on patients with a pacemaker, implanted defibrillator, or any other implanted metallic or electronic device.

Recommendations

Users are recommended to read the entire instruction manual carefully to make the most of the device’s use, effectiveness, and safety. Use the Quattro 2.5 clinical electrotherapy unit only for the purposes that it has been intended to fulfill. Physician-recommended precautions should be followed when treating patient with heart disease, epilepsy, or who tend to bleed internally, or who have had a recent surgical procedure, as well as pregnant women.
