The purpose of this study is to determine whether application of Transcutaneous Electrical Nerve Stimulation (TENS) is effective on habituation to electrical current whether delivered at a fixed frequency of 100 Hz or at patterned frequency. The secondary purposes are to determine the effectiveness on mechanical pressure pain and the subjective perception of the subjects regarding habituation and comfort of the different stimulations.
Low frequency and low intensity TENS showed strong evidence of inefficiency while conventional high frequency TENS (around 100Hz) applied at "strong but comfortable" intensity proved strong evidence of efficacy on pressure pain. In addition, some studies have shown the importance of current intensity in the effect of TENS.
Either in clinical practice and in research, TENS intensity is usually adjusted according to the sensation of the subjects "strong but comfortable" "strong just below the motor threshold", ...). Usually throughout the TENS applications there is a phenomenon called "habituation" that involve a wide decrease of the sensation of the current applied, even though the perception the output-parameters are maintained.
In this sense, It has been seem that adjusting the intensity throughout the TENS intervention produced a greater hypoalgesic effect than when the intensity remained fixed.
On the other hand, most TENS devices offer the possibility of modulating current with the aim of preventing habituation phenomenon. The modulation of the electric current consists of changing the characteristics of the current (pulse width, pulse frequency, ...) every few seconds during the intervention. Nevertheless, the most common pattern used is the frequency modulation. However, there is a lack of evidence regarding what it is the better methods to avoid habituation during a TENS application.

Loss of detectable antigen from the surface of a cell after incubation with antibodies. This is one method in which some tumors escape detection by the immune system. Antigenic modulation of target antigens also reduces the therapeutic effectiveness of treatment by monoclonal antibodies.
Non-ionizing electromagnetic energy in the frequency range of 100 gigahertz to 10 terahertz which spans from the mid-INFRARED RAYS frequency to the high-frequency edge of the MICROWAVES band.
Ventilatory support system using frequencies from 60-900 cycles/min or more. Three types of systems have been distinguished on the basis of rates, volumes, and the system used. They are high frequency positive-pressure ventilation (HFPPV); HIGH-FREQUENCY JET VENTILATION; (HFJV); and high-frequency oscillation (HFO).
Electromagnetic waves with frequencies between about 3 kilohertz (very low frequency - VLF) and 300,000 megahertz (extremely high frequency - EHF). They are used in television and radio broadcasting, land and satellite communications systems, radionavigation, radiolocation, and DIATHERMY. The highest frequency radio waves are MICROWAVES.
