Spinal Cord Stimulation for CRPS: Addressing the Underdiagnosed and Undertreated Reality of CRPS

Updated: Apr 6, 2023


Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that can dramatically impact a person's quality of life. Unfortunately, CRPS often goes undiagnosed and untreated due to its elusive nature and the lack of awareness among medical professionals and the general public. Spinal cord stimulation (SCS) has emerged as a promising treatment option for CRPS patients, offering hope for those struggling with this debilitating condition. In this blog post, we will discuss the use of SCS for CRPS, highlighting its effectiveness and the need for increased awareness of this often undiagnosed and undertreated condition.

Understanding Complex Regional Pain Syndrome (CRPS):

CRPS is a chronic pain disorder that typically affects one limb, often following an injury, surgery, or trauma. The condition is characterized by severe, persistent pain that is disproportionate to the initial injury. CRPS can also cause changes in skin color, temperature, and swelling in the affected area. There are two types of CRPS:

  1. CRPS Type I (previously called Reflex Sympathetic Dystrophy or RSD): This form of CRPS occurs without a confirmed nerve injury.

  2. CRPS Type II (previously called Causalgia): This type of CRPS results from a confirmed nerve injury.

The Elusive Nature of CRPS:

CRPS remains underdiagnosed and undertreated for various reasons:

  • Lack of Awareness: Many healthcare providers are unfamiliar with CRPS, leading to misdiagnosis or delays in proper treatment.

  • Complexity: CRPS symptoms can vary widely and change over time, complicating the diagnostic process.

  • Limited Research: The exact cause of CRPS is still not fully understood, and limited research funding hinders the development of new diagnostic tools and treatments.

Spinal Cord Stimulation for CRPS:

Spinal cord stimulation is a minimally invasive treatment that has shown promising results in managing CRPS pain. The procedure involves implanting a small device (spinal cord stimulator) under the skin, which delivers low-level electrical impulses to the spinal cord. These impulses help block pain signals from reaching the brain, providing significant pain relief for CRPS patients.

Advantages of SCS for CRPS:

  1. Targeted Pain Relief: SCS directly targets the spinal cord and pain pathways, making it particularly effective for neuropathic pain conditions like CRPS.

  2. Customizable Treatment: SCS devices can be adjusted and programmed according to each patient's unique pain patterns and needs.

  3. Minimally Invasive: The SCS implantation procedure is minimally invasive and reversible, providing a safer alternative to more invasive surgeries.

  4. Reduced Reliance on Medications: With successful SCS treatment, patients may experience reduced dependence on pain medications, minimizing potential side effects and drug interactions.

The Need for Increased Awareness:

To improve the diagnosis and treatment of CRPS, increased awareness is crucial. This includes:

  • Educating healthcare providers on CRPS symptoms, risk factors, and treatment options.

  • Increasing research funding for developing better diagnostic tools and therapies.

  • Advocating for CRPS patients to ensure they receive proper care and support.


Spinal cord stimulation offers a promising treatment option for those suffering from Complex Regional Pain Syndrome, a condition that often goes undiagnosed and undertreated. By increasing awareness among medical professionals and the public, we can improve the lives of CRPS patients and ensure they have access to effective treatment options like SCS.
