Any pain that lasts longer than 12 weeks is considered chronic. Chronic pain can be challenging to treat, especially in the lower back. However, studies reveal that high-frequency spinal cord stimulation (SCS) may provide an effective, low-cost treatment option to alleviate chronic lower back pain.
What Is Spinal Cord Stimulation?
Spinal cord stimulation uses a device surgically implanted into the spinal cord to deliver electricity that blocks or changes nerve activity to reduce the pain communications reaching the brain.
Often, SCS is a last resort for patients who have exhausted non-surgical treatment options for chronic pain relief.
What Is Different About High-Frequency SCS?
Original SCS treatments used low-frequency (50 Hz) electrical pulses to block or modify nerve signals, a practice approved by the FDA in 1989. However, low-frequency SCS has some adverse side effects, most notably paresthesia, which is a feeling of tingling or prickling.
High-frequency SCS uses waveforms running up to 10,000 Hz, a treatment approved by the FDA in 2015. Until recently, the main benefit of choosing high-frequency over low-frequency SCS was the newer treatment’s lack of paresthesia as a side effect.
A new study shows that high-frequency SCS may offer additional significant benefits.
How Is High-Frequency SCS Better Than Low-Frequency?
A new research study published in the Journal of Bioelectronic Medicine revealed that high-frequency (10,000 Hz) SCS can be more effective in alleviating pain and reducing prescription painkiller requirements for patients with chronic lower back pain.
High-frequency SCS delivers stimulation pulses at higher wavelengths but in shorter duration and lower amplitude.
The study followed patients who received SCS, with some receiving low-frequency SCS and others receiving high-frequency SCS. Looking at male and female patients at three and six months post-implantation, all patients showed an improvement in their perceived pain.
However, patients receiving high-frequency SCS experienced a more significant reduction in their perceived pain and required fewer opioids to manage their chronic pain.
In addition to reducing pain, high-frequency SCS offers a low-cost alternative to many other chronic lower back pain treatments.
Can High-Frequency SCS Treat More Than Back Pain?
In addition to serving as an effective treatment for managing back pain, high-frequency SCS can also treat several chronic pain conditions, including:
- Chronic neck pain
- Complex regional pain syndrome
- Peripheral neuropathy
- Refractory angina
As researchers continue to study how SCS works to treat challenging chronic pain conditions, the treatment is gaining popularity as a safe and effective way to reduce debilitating chronic pain.
