The Center for Neuromodulation was created with a goal to provide our region with expertise in state-of-the-art technologies to treat chronic pain. We perform spinal cord stimulation and peripheral nerve stimulation for treating patients with severe refractory pain of various causes. The field of neuromodulation for pain is becoming increasingly complex,and we believe that patients are best served by experts who are very familiar with these emerging technologies. The Center for Neuromodulation combines expertise within OHSU's Neurosurgery Department and the Comprehensive PainCenter, ensuring that patients get the best care.


  • Severe pain of the trunk and limbs
  • Post-laminectomy syndrome (Failed Back Surgery Syndrome)
  • Complex regional pain syndrome (Reflex Sympathetic Dystrophy and Causalgia)
  • Pain due to neuropathy or neuralgia (Groin pain, post hernia repair surgery pain, post vasectomy pain)
  • Pain that persists despite treatment with surgery, injections, medication, physical therapy and other modalities.

Treatment Options

  • Conventional spinal cord stimulation
  • High frequency spinal cord stimulation
  • BurstDR and high frequency waveforms
  • Peripheral nerve stimulation

Our Expert Physicians

We believe that spinal cord stimulation is a safe, minimally invasive therapy that can dramatically improve pain and function in carefully selected patients, without the typical side effects encountered withmedications or additional surgery. Our group consists of a neurosurgeon, Ahmed Raslan M.D., and a pain physician, Andrei Sdrulla M.D., Ph.D. who have significant experience and a deep understanding of all aspects of neuromodulation for chronic pain. We are active both clinically and in basic and translational research (link), and frequently enroll patients in clinical trials (link). We work together to offer a personalized approach to pain reliefusing all the available state-of-the-art technologies in a friendly, down to earth manner.
