• Symptomatic relief of chronic intractable pain post traumatic and post surgical pain. (IF-mode)
• Relaxation of muscle spasms
• Prevention or retardation of disuse atrophy
• Increasing local blood circulation
• Muscle re-education
• Immediate post surgical stimulation of calf muscles to prevent deep venous thrombosis
• Maintaining or increasing range of motion

• The IF8000 offers two channel interferential operation with four electrodes as well as a two electrode configuration.
• The IF8000 has five frequency shift options, allowing you to program the unit for specialized rehabilitation needs.
• C  Continuous mode.  Beat frequency remains constant during the entire treatment period.
• 1/1  Abrupt.  Beat frequency shifts in one second durations from a 30% below to a 60% above the set frequency.
  (Thus at frequency of 10 Hz at 1/1 the net delivered beat frequency would modulate from 7 Hz to 16 Hz every other second)
• 1/1  Ramped.  Beat frequency ramps in one second durations from a 30% below to a 60% above the set frequency.
• 6/6  Abrupt.  Beat frequency shifts in six second durations from a 30% below to a 60% above the set frequency.
• 6/6  Ramped.  Beat frequency ramps from a 30% below to a 60% above of the set frequency once per 6 second interval, with a slow, up and down ramping transition.
• The IF8000 offers a choice between constant stimulation and a neuromuscular stimulation option.  The muscle stimulator option has a 6 second ON/6 second OFF duty cycle and for additional comfort a 1 second ramp up and 0.5 second ramp down.  The frequency shift options are functional during muscle stimulation.
• The IF8000 has a constant current output that makes it more comfortable and safer than most other available devices.
• The IF8000 automatically shuts off after 20 minutes treatment or any other preset time.
• The IF8000 is portable, wearable and easy to use.
• The IF8000 is covered by a three year limited warranty.
• The IF8000 is controlled by a micro-processor that allows advanced programming and many safety features.
• The IF8000 has digital display.
• The IF8000 records compliance data, such as usage time and number or times used.
