300PV™

300pv_anchorLarger View

This portable Neuromuscular Stimulation (NMES) device is a multi-function electrotherapy system, with the ability to function as a NMES, TENS, and High Volt Device. The 300PV offers all the flexibility and power of the larger, more costly tabletop “clinic” devices in a portable package that runs on rechargeable AA batteries. This makes it ideal for both clinic and home use.

The 300PV generates a low level electrical stimulus to cause muscle contraction. Commonly adjusted parameters are waveform, pulse rate, and the length of device operation (duty cycle).

  • Easy to read LCD display
  • 9 NMES and 4 High Volt pre-programmed regimens for a broad range of applications
  • Full parameter control for clinicians that choose to customize individual programs
  • Step-by-step setup and use
  • Program lock to ensure patients’ use as prescribed outside of clinic
  • Digital output-intensity is reproducible from patient-to-patient

Q: Can I use an NMES device as a TENS device for pain control?
A: Yes. The 300PV can also be programmed to deliver basic TENS.
Q: Do you have a motor point chart to help find the best electrode placements?
A: Yes.
Q: How long and how frequently should NMES be used to effectively strengthen a muscle?
A: Depending on the specific rehabilitation goals, a patient with an intact neuromuscular system can use NMES to facilitate muscle contractions for 30-60 minutes/day to achieve optimal outcomes. Please see the references for disuse atrophy in the section for additional information. Follow your physician or therapist's instructions for using this device.
Q: Can NMES be used if a muscle is denervated?
A: No. If a muscle is completely denervated, then direct current is required to elicit a muscle contraction.
Q: If Hi-volt is used to treat swelling or circulation problems, what is the recommended setup for the device?
A: The 300PV Hi-volt preprogrammed regimen 1.
Q: If the Hi-volt application is used, what electrodes come with the 300PV?
A: (1) 4 x 7 dispersive electrode and (2) 2 x 2 reusable electrodes.
Q: How do I lock or unlock the 300 PV settings?
A: To lock programs into the device, follow the LCD screen prompts. To unlock programs, turn the device off by pressing the on/off button. While the display screen is black, simultaneously press and hold the pause and prev. buttons until the screen displays the "Unlock" message. Then follow the LCD prompts. Refer to pages 27-29 of the instruction manual.
Q: What can I do if the batteries don't last for more than two treatments when using the IF setting?
A: Empi offers rechargeable battery packs, which allow for numerous treatments without battery depletion.
