2. HOW DOES THE DIRECT TENS™ DEVICE FUNCTION... Via electrodes attached to the skin, Direct TENS™ sends electrical pulses to the nerves. This will block the pain impulses. Four electrodes – two for each channel – can be connected to the device. Pain relief is most efficient during stimulation, but the effect can last after the treatment.
™ 2.1. TENS therapy principle Two pain theories play an important role in the application and parameter settings of the Direct TENS™ device: • The Gate Control Theory by WALL and MELZACK (1965) • The Endorphine Theory by ERIKSON and SJÖLUND (1979) According to the Gate Control Theory, weak TENS impulses block the pain impulses travelling to the brain (sensor stimulation).
