Product Description

BLD Portable 2 Channel Interferential EMS Unit, IF4250D

The model BLD IF4250D is used to treat symptomatic relief and management of chronic pain and/or as adjunctive treatment in the management of post-surgical and post-traumatic acute pain. The device produces beat frequency in the range 1-250 Hz. The BLD IF4250D delivers very precise and repeatable Interferential therapy. It is engineered with an ultra low power microcontroller for precision, safety, durability and reliability.

What is interferential therapy?
Interferential Electric Stimulation is a unique way of effectively delivering therapeutic frequencies to the tissue. Interferential stimulators use a fixed carrier frequency of 4,000Hz per second and also a second adjustable frequency of 4,001-4,4400Hz per second. When the fixed and adjustable frequencies combine with each other (heterodyne), they produce the desired signal frequency (interference frequency) at the point of intersection between the electrodes. This causes the stimulation to concentrate deep in tissues as well as at the surface of the skin. It provides more analgesic or nerve blocking effect.
