iTENS Terapix Dual Channel Digital TENS EMS Machine background

iTENS Terapix features 2 independent channels that facilitate TENS or EMS treatments of 2 different body areas at the same time. The iTENS Terapix can even be used by 2 different people at the same time as the intensity of the stimulation can be adjusted independently on each channel depending on personal tolerance or preference.

iTENS Terapix has a selection of 20 pre-set programs for pain relief and another 20 programs for the EMS muscle stimulation. Time and intensity are adjustable on all pre-set programs on each channel individually, which means that you can apply the same treatment at different intensity level to different body areas - if required. Additionally, there are also 10 custom programs for pain relief and 10 custom programs for EMS that can be conveniently programmed to personal needs.    

For ease of use, the LCD on the iTENS unit displays area of the body that the individual pre-set programs treat. The current used by the device is biphasic rectangular current that reduces strain on the muscles and reduces discomfort caused by fatigue. You will note that there is more than one program that addresses pain in the same body area. You should note that albeit the areas are the same, the frequency of the current is different, because different frequencies address different muscle fibres and different muscular issues that cause pain and discomfort. For instance, the low frequencies up to 15 Hz work on slow twitch muscle fibres, whilst the fast twitch fibres respond better to frequencies over 35 Hz. Higher frequencies (i.e. over 45 Hz) help to improve muscle elasticity and help to increase muscle strength, helping to combat muscle tension and fatigue. You should identify the program or programs designed to address the pain/discomfort in body area relevant to you and then establish, which program works best for you, using the above information about the application of frequencies as a guide to select suitable program(s).

Using iTENS Terapix TENS EMS is easy, effective and safe. TENS and EMS therapies are proven to be effective and have been thoroughly tested for safety. When used as a TENS machine for pain relief, use as required. For best EMS outcomes, such as body toning, muscle firming or body outline shaping, use the iTENS Terapix for up to 3 times a day for 30 minutes a time.  When desired outcomes are achieved, use the device as required or at least 3 times per week to maintain results.
