Abstract

The invention relates to spinal cord stimulation with interferential current. According to the invention, a stimulator and a method for the treatment of intractable pain syndromes by electrical stimulation of the spinal cord are disclosed. An example method includes positioning a first pair of implantable electrodes to a dura matter in an epidural space proximate to a subject's spinal cord at predetermined locations, positioning a second pair of implantable electrodes to the dura matter in the epidural space proximate to the subject's spinal cord at predetermined locations, and transmitting signals of first and second frequencies through the first and second pairs of implantable electrodes respectively, so that the signals of the first and second frequencies interfere with each other to produce at least one beat signal proximate to the subject's spinal cord. The at least one beat signal has a frequency within a range of more than 250 Hz to about 15,000 Hz.

Description

technical field [0001] The present disclosure relates generally to spinal cord stimulation, and more particularly to an apparatus and method for electrically stimulating the spinal cord using interfering current patterns for the treatment of chronic pain conditions. Background technique [0002] Electrical stimulation of the spinal cord in the back (spinal cord stimulation (SCS)) has been developed as an effective therapeutic tool for the treatment of chronic pain conditions. However, little is known about the sites of activation or the neural mechanisms evoked by SCS that reduce pain and promote functional changes in somatic and visceral structures. [0003] Spinal cord stimulation is most commonly used in patients with chronic intractable pain syndrome. It is also used to treat movement disorders and is occasionally used after a head injury. However, one complication of SCS is the adaptation, or modulation, to the stimulus signal. Companies that manufacture spinal stimu...
