A transcutaneous electrical nerve stimulation device for treating a user's lower back pain or discomfort is provided. The inventive device comprises a stimulation pad with an array of electrodes therein. A controller communicates with the electrodes to energize / de-energize them in a patterned, sequential manner. The patterned actuation of the electrodes in a sequential fashion provides electrical impulses to the patient's skin, simulating a transverse wave motion. The transverse wave motion simulation provides the user with the effect of the electrical stimulation combined with the mechanical tissue stimulation received in traditional massage therapy, resulting in improved pain and discomfort relief. The device may use programs stored in the controller. Alternatively, the user may manually actuate one or more electrodes as well as manually move the electrode actuation to concentrate on a specific lower back region using an electrostatic touch pad or the equivalent. The user may also use voice commands to access the stored programs, move the electrode stimulation region, change the electrode actuation intensity and / or dwell time. The device may store the user's manually-generated routines for repeating when desired. A visual display may provide feedback to the user regarding the electrode actuation position and pattern.
