Complex Regional Pain Syndrome (CRPS), formerly known as Reflex Sympathetic Dystrophy (RSD), is a challenging and often misunderstood condition. Despite its prevalence — affecting up to 9% of the population — it remains underdiagnosed and undertreated. As healthcare providers, it's crucial to recognize this condition and understand the role that laser therapy can play in its management. In this blog post, we’ll dive into the research behind CRPS and how laser therapy can offer relief.
What is CRPS?
CRPS is a pain disorder that typically follows an injury or trauma, like a sprain, surgery, or even excessive icing, as in several cases I encountered. It's characterized by extreme pain disproportionate to the initial injury, and the pain often persists well beyond the usual healing time. This pain is typically not confined to a specific nerve or dermatome, making it challenging to diagnose. There are two types of CRPS:
Type 1: No nerve injury is present, and the pain often spreads across the affected area, creating extreme sensitivity and discomfort.
Type 2: There is a clear nerve injury, often following trauma or surgery.
Patients with CRPS may experience a range of symptoms beyond pain, including changes in skin color, temperature asymmetry, nail growth asymmetry, swelling, and even motor dysfunction like weakness or limited range of motion. The pain is often described as hypersensitive to touch, air movement, or even light pressure.
The Struggle with Diagnosis
Despite its significant impact, CRPS is often mistaken for other conditions, such as somatoform disorders, especially because it typically affects women aged 40-60. The pain and symptoms can be so severe that some patients are wrongly labeled as "dramatic" or "drug-seeking." This lack of understanding can leave patients feeling frustrated, dismissed, and without hope.
Recognizing CRPS requires careful observation. If a patient presents with severe, ongoing pain after what would typically be a mild injury (like an ankle sprain), along with symptoms like hypersensitivity, temperature changes, and swelling, CRPS should be considered. However, there's no single test for CRPS — it’s primarily diagnosed through a process of elimination.
Laser Therapy for CRPS: A Promising Solution
Research has shown that low-level laser therapy (LLLT) can be a highly effective treatment for CRPS, offering significant pain relief and reducing swelling (edema). A study published in the Turkish Journal of Physical Medicine and Rehabilitation in 2013 compared LLLT with interferential current therapy (IFC) in treating CRPS. The results were compelling: laser therapy was found to have a more significant impact on pain intensity and edema reduction.
In this study, participants received laser therapy at an 810 nm wavelength with pulsed light frequencies at 70 Hz, 640 Hz, and 5,000 Hz. The treatments were applied to specific points on the affected joint and painful areas, totaling 1.5 joules per centimeter squared per session. After just 10 treatments over two weeks, patients in the laser therapy group showed impressive improvements.
The researchers suggest that laser therapy works by:
Modulating pain perception through endogenous opioid production.
Reducing inflammation and increasing local circulation.
Enhancing tissue oxygenation and promoting healing.
Why Does Laser Therapy Work?
While the exact mechanisms are still under study, laser therapy appears to have a multi-faceted effect on CRPS. It helps control neurogenic inflammation, which is thought to be the root cause of CRPS Type 1, by normalizing the sympathetic nervous system tone. Laser light also helps stabilize cell membranes and reduces the entry of sodium ions into the cells, which plays a key role in reducing pain.
Additionally, laser therapy stimulates reduction of the level of prostaglandin E-2 and has inhibitory effects on cyclooxygenase 2 while promoting tissue regeneration, all of which is essential for healing in cases of CRPS.
Key Takeaways for Healthcare Providers
Early Recognition: CRPS is often underdiagnosed and misdiagnosed. Be vigilant in looking for signs like extreme pain following mild injuries, hypersensitivity, and swelling. A thorough evaluation is crucial to avoid dismissing legitimate cases.
Multidisciplinary Approach: While physical therapy and medications like Lyrica or Gabapentin can be helpful, combining these approaches with laser therapy may yield better results for patients with CRPS.
Laser Therapy as a Lifeline: Laser therapy offers a non-invasive, effective solution for CRPS patients. It can help reduce pain, inflammation, and improve overall quality of life, especially for those suffering from severe cases.
If you have laser therapy equipment in your clinic, consider using it to treat CRPS patients. It has the potential to make a significant difference in their recovery. In my experience, laser therapy has provided substantial relief for CRPS patients, allowing them to regain mobility and reduce reliance on medications.
