'Premod' is similar in its benefits and ease of use for patients as interferential current. The main difference between the two is how the current is delivered to the patient’s muscle tissue. With premod current, a single channel is used to mix the frequencies prior to delivery of the current through the electrode of the body (using two electrodes rather than four). This is beneficial when treating areas of the body that have less space available for electrode placement. This makes it the perfect choice to use on smaller muscle groups and joints such as the elbow, ankle, foot, and hands.

Frequency Sweep For Interferential Curren

# data[].attributes.body
Nerves will accommodate to a constant signal & a sweep (or gradually changing frequency) is often used to overcome this problem. The principle of using the sweep is that the machine is set to automatically vary the effective stimulation frequency using either pre-set or user set sweep ranges. The sweep range employed should be appropriate to the desired physiological effects (see below). It has been repeatedly demonstrated that ‘wide’ sweep ranges are ineffective whenever they have been tested or evaluated in the clinical environment

A transdermal delivery system in which a substance bearing a charge is propelled through the skin by a low electrical current. This method can be used to drive a drug across the skin barrier.

therapy is an effective therapy option used by many physiotherapy clinics to relieve pain and accelerate the self-healing process, getting your body back to a healthy, pain free state. The high frequency signals of an IFC penetrate through the skin into deeper lying muscle tissues

The continuous vs burst protocols were evaluated (i.e. continuous 2500Hz or 2500Hz burst at 10ms intervals). There was no significant difference in the maximal force generated, but the burst mode generated the same result with less current having been applied (50% less). The recommendation is therefore that the stimulation should be applied with a 2500Hz carrier medium frequency sinusoidal alternating current, burst at 50 Hz (10ms ON : 10ms OFF) at a maximum tolerable level.

Benefits of Electric Muscle Stimulation Therapy

# data[].attributes.body
The mechanism of the muscle stimulation is it delivers small pulsating currents directly on the muscles, which in turn promotes muscle stimulation, blood circulation and muscle healing. The main benefit of electrical muscle stimulation therapy is pain relief

# data[].attributes.body
The stimulation was applied at a range of 'medium' frequencies (100-500-1000-2500-3000-5000Hz) and it was found that as the stimulating frequency increased, there was a greater comfort for the recipient, and it was therefore (predictably) identified that a greater current could be delivered to the muscle with increased (higher) frequencies.

The stimulation was found to generate fatigue if delivered for more than 10 seconds (at maximal tolerable intensity). Various interpulse rest phases were tested ranging from 10 through to 50 seconds. Both the 40 and the 50 seconds rest were identified as effective, though some subjects appeared to start to demonstrate fatigue with the 40 seconds rest, hence the 50 second period was subsequently adopted.
