Detailed Description

All ReliaMed EMA and IF units have protective caps over the amplitute adjusment knobs to prevent unintended changs to the pulse amplitude. All Digital ReliaMed units (TENS, EMS and IF) have a patient compliance feature that allows the prescribing doctor to monitor the patient's usage of the device. All ReliaMed Electrotherapy units come in hard-sided protective plastic cases.

Specifications:

Timer: 15 min; 30 min • Adjustable 0-60 mA peak into 500 ohm load each channel, constant current.

Interferential electrical stimulation's is a unique way of effectively delivering therapeutic frequencies to tissue. Conventional TENS and Neuromuscular stimulators use discrete electrical pulses delivered at low frequencies of 2-160 Hz per second.

However, Interferential stimulators use a fixed carrier frequency of 4,000 Hz per second and also a second adjustable frequency of 4,001-4,400 Hz per second.

When the fixed and adjustable frequencies combine (heterodyne), they produce the desired signal frequency (Interference frequency).

Interferential stimulation is concentrated at the point of intersection between the electrodes. This concentration occurs deep in the tissues as well as at the surface of the skin.
