Background-Low back pain is a common, costly & often chronic condition, estimated to affect 85% of people in their lifetime. A form of electronic pain control currently in use is TENS. Although the exact mechanism is not completely understood, it is proposed that its effectiveness is based on the gate control theory. Biowave has developed new patentable technology & a related device in the field of electromedicine. The device delivers a precise electrical signal to a specific volume of tissue in the body, which blocks the transmission of pain impulses.
