Laser Evoked Potentials (LEP) in Patients with Low Back Pain and Healthy Volunteers

(IRB#: IRB_00158608)

People with low back pain may need testing for diagnoses and treatment evaluations. Research is needed to assess if more quantitative measures such as laser evoked potential (LEP) and quantitative sensory testing can be used to tease out differences in patients with low back pain problems and better determine the treatment outcomes. The information we gain may aid future patients.
