Neuromodulation in Granada Hills

What Is Neuromodulation?

Neuromodulation is a class of advanced pain management therapies that use precisely delivered electrical signals to alter — or “modulate” — the way the nervous system processes and perceives pain. Rather than masking pain with medication, neuromodulation works by directly targeting the neural pathways responsible for transmitting pain signals, interrupting those signals before they reach the brain.

This approach is particularly valuable for patients with chronic pain that has been difficult to control through conventional means. Neuromodulation therapies are minimally invasive and reversible, and many patients experience dramatic improvements in pain levels and quality of life. At Modern Pain Solutions in Granada Hills, CA , Dr. Lim offers a full suite of neuromodulation treatments tailored to each patient’s unique condition and anatomy.

Spinal Cord Stimulation (SCS)

Spinal Cord Stimulation is one of the most well-established and effective neuromodulation therapies available for chronic pain. During SCS therapy, a small pulse generator is implanted under the skin, connected to thin electrode leads that are carefully positioned in the epidural space near the spinal cord. The device delivers gentle electrical pulses that interfere with pain signals traveling to the brain — effectively replacing the sensation of pain with a mild tingling sensation or, with newer waveform technologies, no sensation at all.

SCS is particularly effective for conditions including:

• Failed back surgery syndrome (FBSS)
• Complex regional pain syndrome (CRPS)
• Neuropathic leg or arm pain
• Chronic back and neck pain that has not responded to other treatments
• Peripheral vascular disease-related pain
• Post-herpetic neuralgia

Before permanent implantation, patients undergo a trial period with an external device to evaluate whether SCS provides meaningful relief. Only after a successful trial — in which patients typically experience at least 50% pain reduction — is a permanent system implanted.

Dorsal Root Ganglion (DRG) Stimulation

Dorsal Root Ganglion Stimulation is a more targeted form of neuromodulation that specifically addresses the dorsal root ganglion — a cluster of sensory nerve cell bodies located just outside the spinal canal at each spinal level. The DRG plays a critical role in how pain signals from specific areas of the body are processed and transmitted.

By delivering electrical stimulation directly to the DRG, this therapy can provide highly precise pain relief to well-defined anatomical regions — such as the foot, knee, groin, or chest wall — that are difficult to target effectively with traditional SCS. DRG Stimulation is especially beneficial for patients with:

• Complex regional pain syndrome (CRPS) affecting a specific limb or extremity
• Chronic pelvic or groin pain
• Post-surgical pain syndromes in localized areas
• Focal neuropathic pain unresponsive to conventional SCS

Peripheral Nerve Stimulation (PNS)

Peripheral Nerve Stimulation targets specific peripheral nerves — the nerves that extend beyond the brain and spinal cord to supply sensation and motor function to the limbs and body. Electrode leads are placed near the targeted nerve, and a pulse generator delivers gentle electrical impulses that disrupt pain signal transmission.

PNS is an excellent option for patients experiencing localized, chronic pain in areas such as the arms, legs, lower back, or other regions where the pain can be traced to a specific peripheral nerve. It is also used for occipital nerve stimulation to address chronic headaches and migraines. Common conditions treated with PNS include:

• Chronic limb pain following injury or surgery
• Peripheral neuropathy
• Shoulder and extremity pain — see our Shoulder Pain page
• Intractable lower back pain — related to our Back & Neck Pain services
• Post-amputation pain

Why Choose Modern Pain Solutions for Neuromodulation?

Neuromodulation is a highly specialized field that demands deep expertise and precise technical skill. Dr. Lim’s fellowship training in interventional pain medicine and his extensive clinical experience with complex pain syndromes make him exceptionally well-qualified to evaluate, select, and implement neuromodulation therapies for his patients.

Key advantages of pursuing neuromodulation therapy at Modern Pain Solutions include:

• Individualized Evaluation: Dr. Lim conducts a thorough assessment of your pain history, prior treatments, imaging, and functional goals before recommending neuromodulation.
• Trial Period First: All spinal cord and DRG stimulation implants are preceded by a reversible trial to confirm effectiveness before any permanent hardware is placed.
• Minimally Invasive Implantation: Procedures are performed with precision using imaging guidance, minimizing tissue disruption and recovery time.
• Ongoing Support: Dr. Lim and our team provide device programming, follow-up care, and adjustment of stimulation parameters to optimize your results over time.

Neuromodulation may also be combined with other services at Modern Pain Solutions, including injection therapies, PRP therapy, and minimally invasive spine procedures, as part of a comprehensive pain management strategy.
