Post Market Study of the Electrophysiological Course of Low Back Pain Using CERSR Technology

The purpose of this research study is: 1. to measure with CERSR® (Computerized Electrophysiological Reconstruction of the Spinal Regions) the electrical signals made by the muscles in the lower back during the treatment of the low back pain, and 2. to study the changes which take place in these muscles with treatment. The device is non-invasive which means nothing is put into your body. The CERSR® pad is an adhesive (sticky) array (ordered rows) of electrodes. The investigators hope to find information about the quality of the muscles' electrical signals in reaction to injury causing back pain, which will improve understanding of the nature of back pain and back injury. The investigators also hope to improve treatment by creating a simple test, which will tell us objectively (through computerized measurement) whether the treatment is helping.
