Back Marvel is a pain therapy belt specifically targeted to offer relief from agonizing back pain. This belt has been developed by doctors on a technology based on TENS therapy which stands for Transcutaneous Electrical Nerve Stimulation.
Back Marvel uses four contacts on the back of the belt to send electrical impulses to the underlying nerve fibres of the lower back where the pain sensors are located. These impulses in return stimulate the nerves and muscles, which block the pain immediately.
