The Secret of Free Q

Each Free Q single electrode is a TENS unit in itself, having a positive (cathode) and negative (anode) pole within the same cup. This allows for individual adjustment of each electrode and the use of only one, or as many electrodes as required, all controlled by one lightweight remote control device. Single electrodes are best for local stimulation and acupuncture treatment.

Dual Electrodes have one pole within each cup. The polarity alternates between the two electrodes during treatment, allowing for a range of effects at each electrode. These cups are best for wide-area stimulation and interferential therapy (2 x dual-electrodes are required for interferential therapy).
