Millions of people worldwide suffer from chronic back pain in the lumbar spine. One of the most important treatment methods is the TENS (Transcutaneous Electrical Nerve Stimulation) electrotherapy, which uses small electrical nerve-stimulating pulses to provide non-invasive drug-free pain relief. The WiTouch Pro is a TENS unit that is designed without the cumbersome battery packs and wired electrodes typical of traditional devices of this kind. The innovative wireless unit integrates all necessary elements in a compact and aesthetically appealing housing. A complex dual overmoulded body assembly ensures that the highly flexible electrode wings comfortably hug the body’s contours. Thus, the device is easy to transport and can be worn discreetly underneath the clothes for long periods. The WiTouch Pro is intuitively operated, also via remote control, it is pleasant to the touch and highly flexible in use. A combination of low-energy wireless chips and an intelligent software design allows for cost-efficient use even over a long period of time. This design concept presents a paradigm shift for TENS. It provides new treatment qualities for individual pain relief and a high degree of mobility.
