Bob Johnson from Medfaxx, www.medfaxxinc.com, shows proper tens electrode placement ( pain patch) ( tens pad) and tns electrode size for back pain. Interferential treatment is best for back pain and the Infrex combines interferential with tens therapy. Infrex on interferential therapy mode provides carryover pain relief so the patient has fewer treatments but longer pain relief between treatments with the portable Infrex Interferential Tens Unit. Also referred to as residual pain relief without drugs.
