1 Product Description
1.1 The 300 PV Electrotherapy System
The Empi 300 PV is a state-of-the-art, multifunction electrotherapy device. It has
the ability to provide two channels of conventional NMES, conventional TENS
and a single channel of High Volt (Galvanic Stimulation) electrotherapy. This
wide-ranging capability allows the clinician to employ electrotherapy throughout
the healing cycle with a single device. Furthermore, programmability of the device
allows for customization to each patient's needs.
The 300 PV Neuromuscular Electrical Stimulation (NMES) feature produces an
electrical stimulus that, when properly applied, activates specific muscles and/or
muscle groups. The waveforms are fully programmable for maximum treatment
flexibility.
The 300 PV has a High Volt feature that can be used for increasing local blood
circulation.
The 300 PV has thirteen preprogrammed regimens for NMES, TENS, and HV, or 3
available Sport PPR's. Treatment duration time is also controllable. In addition, the
device may be set for either symmetric or asymmetric biphasic waveforms.
1.2 How Does Electrotherapy Work?
The device produces a mild electrical current transmitted via lead wires to
electrodes placed on the skin over the motor point of the targeted muscle.
Stimulation of motor end plates cause nerve depolarization and activation of
muscle fibers, resulting in a muscle contraction.
When applied as a TENS device, electrical stimulation may directly block
transmission of pain signals along nerves. In addition, electrical stimulation has
been shown to promote the release of endorphins, which are natural painkillers
produced by the body.
1.3 The 300 PV Features
The 300 PV device provides many features that permit a range of treatment
options:
• Two independent digital intensity controls
• Timed therapy sessions
• Continuous or cycled stimulation
• Adjustable pulse rates
• 13 preprogrammed regimens for NMES, TENS, and HV, or 3 available
Sport PPR's
