Neurostimulation Is Rewiring How We Treat Chronic Pain
Over 50 million Americans live with chronic pain, yet neurostimulation offers an alternative that doesn’t rely on opioids. It works by sending mild electrical pulses to your nerves or spinal cord, interrupting pain signals before they reach your brain. You can adjust the stimulation with a small remote, targeting specific areas for relief without the side effects of medication.
What Is Neuromodulation for Persistent Pain?
Neuromodulation for persistent pain uses targeted neurostimulation to directly interrupt maladaptive pain signals traveling along nerves to the brain. Instead of masking pain with medication, a small implanted device delivers mild electrical pulses to the spinal cord or peripheral nerves, effectively overriding the faulty circuitry that sustains chronic pain. This approach allows patients to regain control, often reducing pain by 50% or more when other treatments fail.
The core insight is that neurostimulation does not heal tissue; it retrains the nervous system to ignore persistent pain signals, offering a reversible, drug-free on-ramp to functional relief.
For those struggling with neuropathic or post-surgical pain, neuromodulation represents a practical, targeted alternative that can be adjusted as the patient’s condition evolves.
Defining electrical and magnetic therapies for pain relief
Electrical therapies for pain relief, primarily transcutaneous electrical nerve stimulation (TENS), deliver low-voltage pulses through skin electrodes to disrupt pain signals before they reach the brain. Magnetic therapies, such as repetitive transcranial magnetic stimulation (rTMS), use focused magnetic fields to non-invasively modulate cortical excitability, targeting deeper neural pathways involved in persistent pain. Both approaches aim to reduce pain perception without medication, offering drug-free options for chronic conditions. While electrical stimulation is applied locally to peripheral nerves, magnetic stimulation often targets brain regions, providing distinct mechanisms for symptom management.
Electrical and magnetic therapies for pain relief are non-invasive neuromodulation methods: electrical therapies (e.g., TENS) use skin-applied currents, while magnetic therapies (e.g., rTMS) use focused fields to alter nerve activity and reduce chronic pain perception.
How targeted nerve signaling alters pain perception
Targeted nerve signaling alters pain perception by intercepting pain signals at specific neural pathways before they reach the brain. Devices deliver mild electrical pulses to nerves, overriding aberrant pain transmission with controlled paresthesia or sub-sensory modulation. This gating of pain signals effectively competes with nociceptive input, reducing the brain’s perception of intensity. The precise location and frequency of stimulation determine whether pain is replaced, diminished, or blocked entirely.
- Electrical pulses activate inhibitory interneurons in the spinal cord, closing the „gate“ to pain signals.
- High-frequency stimulation disrupts hyperexcitable nerve membranes, normalizing aberrant firing patterns.
- Burst or tonic waveforms desynchronize maladaptive neural circuits that amplify perceived pain.
Types of neurostimulation: implantable versus non-invasive devices
Neurostimulation for chronic pain management divides into implantable versus non-invasive devices, each with distinct practical applications. Implantable systems, such as spinal cord stimulators, require surgical placement of leads near the spine and a pulse generator under the skin, delivering continuous current directly to target neural pathways for severe, refractory pain. Non-invasive devices, including transcutaneous electrical nerve stimulation (TENS), use surface electrodes to deliver controlled electrical pulses through the skin, offering a reversible, low-commitment option for localized or mild-to-moderate pain. The choice hinges on pain severity, patient tolerance for surgery, and need for adjustable versus externally applied therapy. Implantable devices provide deeper, sustained modulation but involve procedural risks, while non-invasive types allow easy user control without permanent hardware.
Mechanisms Behind Pain Relief via Brain and Nerve Stimulation
Sarah’s neurostimulator sends precise electrical pulses into her spinal dorsal horn, instantly activating inhibitory interneurons. This triggers a flood of GABA and glycine that physically block the pain signal before it reaches her brain. Simultaneously, her device targets the periaqueductal gray, the brain’s ancient survival pathway, switching on descending opioid and serotonin circuits that jam incoming pain messages. This dual gating—shutting the spinal gate while the brain drops its own painkillers—is the core mechanism.
The result isn’t a mask, but a cancellation: the nerve traffic of her chronic back pain never completes its journey to consciousness.
Over weeks, repeated stimulation remodels synaptic strength, making this blockade more automatic and durable.
Gate control theory and its role in modern treatment
Gate control theory posits that non-painful input, such as vibration or electrical stimulation, can close a neural „gate“ in the spinal cord, preventing pain signals from reaching the brain. In modern treatment, this principle directly informs transcutaneous electrical nerve stimulation (TENS) and spinal cord stimulation devices. These therapies deliver controlled electrical pulses to large-diameter nerve fibers, effectively overriding smaller pain-carrying fibers. This mechanism explains why many patients experience immediate relief during stimulation sessions. Clinical application now targets specific dermatomes to maximize the segmental pain gating effect, often reducing reliance on pharmacological interventions for chronic conditions like neuropathic pain or failed back surgery syndrome.
Modulating pain pathways through spinal cord stimulation
Spinal cord stimulation (SCS) modulates pain pathways by delivering electrical pulses to the dorsal columns, activating inhibitory interneurons and blocking nociceptive transmission via the gate control theory. This disrupts the ascending spinothalamic tract signal, replacing it with a paresthesia or, with newer waveforms, subthreshold hypoalgesia. Targeting the dorsal horn, SCS also reduces central sensitization by decreasing glutamate release and enhancing GABAergic activity. By altering synaptic plasticity, it recalibrates the dorsal column neuromodulation threshold, providing sustained analgesia without direct tissue damage.
- Depolarizes Aβ fibers to presynaptically inhibit C-fiber input at the substantia gelatinosa
- Downregulates pro-inflammatory cytokines in the dorsal horn microglia
- Reshapes temporal summation by modifying wide-dynamic-range neuron firing patterns
The influence of cortical and deep brain targets on chronic pain
Chronic pain relief depends heavily on where you place the electrodes. Cortical targets, like the motor cortex, modulate how your brain processes pain signals from the body, often reducing the *emotional sting* of persistent discomfort. Deep brain targets, such as the periaqueductal gray or thalamus, work more directly on your body’s natural pain-inhibiting pathways. Choosing between them hinges on your pain’s origin; cortical stimulation tends to help more with nerve pain, while deep brain targets can be powerful for widespread or centralized pain. This is the core of targeted neurostimulation personalization.
Q: Can I choose which brain target is right for my specific pain type?
A: Yes, your doctor uses imaging and symptom mapping to match you. For instance, if standard medications fail, a thalamic deep brain target might be tested for limb pain, while a cortical target could be tried for facial or spinal cord injury pain.
Spinal Cord Stimulation: Indications and Outcomes
After years of failed back surgeries, the patient’s neurosurgeon finally recommended spinal cord stimulation for chronic pain management. The clear indication was persistent neuropathic leg pain unresponsive to conservative care. During the trial lead placement, the patient reported a 70% reduction in burning discomfort. For candidates with failed back surgery syndrome or complex regional pain syndrome, outcomes often include significant functional improvement and reduced reliance on oral opioids. Long-term data show that over half of implanted patients maintain durable pain relief beyond two years, though outcomes depend on precise lead placement and rigorous patient selection to avoid hardware complications or loss of efficacy.
Patient selection criteria for epidural leads and paddles
Patient selection for epidural leads versus paddles hinges on specific anatomical and lifestyle factors. Candidates with robust cervical or lumbar spinal anatomy and no prior extensive scarring may receive percutaneous leads for a less invasive trial. Conversely, paddle leads demand individuals with sufficient epidural space and stable spinal alignment, often following failed lead migration or focal radiculopathy. A history of laminectomy frequently shifts eligibility toward paddles, which offer directional current steering. Uncontrolled bleeding risk or active infection disqualifies all candidates. The decision aligns patient-reported pain patterns with the mechanical durability needed for daily mobility.
Trial phases and long-term implantation success rates
A successful spinal cord stimulator (SCS) journey hinges on a mandatory trial phase, typically lasting 3–7 days, where temporary leads are placed percutaneously. The patient’s reported pain reduction of ≥50% during this trial is the primary predictor for long-term implantation success rates. Following implantation, sustained analgesia at 12–24 months occurs in approximately 60–70% of patients who passed the trial, though failure often results from lead migration, loss of paresthesia coverage, or infection. Rigorous trial protocols, including multi-positional testing, directly correlate with lower explantation rates.
Q: How does the trial phase predict long-term implantation success rates for chronic pain?
A: The trial phase identifies ideal candidates; those achieving ≥50% pain relief with functional improvement have a 70–80% chance of maintaining benefit at one-year post-implant, while poor triallers show significantly higher rates of device removal within two years.
Common conditions treated: failed back surgery syndrome, complex regional pain syndrome
Spinal cord stimulation (SCS) is a primary intervention for two refractory pain conditions. For failed back surgery syndrome (FBSS), SCS targets persistent radicular pain in the legs or thync buttocks following anatomically successful lumbar surgery, offering an alternative to further operations. In complex regional pain syndrome (CRPS), SCS modulates abnormal sympathetic activity and central sensitization, particularly providing relief for the burning, allodynic pain characteristic of CRPS type I. Both conditions demonstrate significant pain reduction and improved function when conservative treatments have failed.
- FBSS: SCS reduces persistent leg and back pain despite prior surgery.
- CRPS: SCS lessens burning pain and allodynia in affected limbs.
- Both conditions: SCS decreases reliance on opioid medications.
- Both conditions: SCS is considered when physical therapy and nerve blocks are insufficient.
Peripheral Nerve Stimulation for Localized Discomfort
Consider a baker whose chronic wrist pain, unyielding to medication, stems from a single nerve branch. Peripheral nerve stimulation for localized discomfort targets precisely that culprit. A thin electrode is placed near the nerve, delivering mild electrical pulses that interrupt the pain signal before it reaches the brain. Unlike broader spinal cord stimulation, this neurostimulation approach focuses on a specific painful territory—like an arthritic knee or a persistent shoulder ache. Over weeks, the brain’s perception of that region shifts, offering relief without systemic side effects. This method works best when the source of pain is anatomically distinct, not diffuse. The patient regains the ability to knead dough or reach for a high shelf without flinching, and sleep through the night without awakening to a dull ache.
Targeting specific peripheral nerves with miniaturized electrodes
Targeting specific peripheral nerves with miniaturized electrodes enables highly localized analgesia by bypassing central nervous system side effects. These advanced leads are precisely implanted near identified pain-generating nerves, such as the occipital or sciatic, delivering pulsed electrical currents that disrupt nociceptive signaling at its source. The electrode’s small size reduces tissue trauma and allows submillimeter proximity to target fibers, enhancing selective stimulation while minimizing off-target recruitment. Adjustable parameters like pulse width and frequency are then fine-tuned to achieve optimal paresthesia coverage directly over the painful dermatomal distribution, providing user-controlled relief for conditions like mononeuropathy or postsurgical neuralgia without systemic drug exposure.
Applications in headache, neuropathy, and postsurgical pain
Peripheral nerve stimulation targets specific nerves driving chronic headache, neuropathy, and postsurgical pain. For headache, leads are placed near occipital or supraorbital nerves to abort or reduce migraine frequency. In neuropathy, stimulation of affected peripheral nerves—such as the tibial or ulnar—interrupts aberrant pain signals, restoring sensation and function. Postsurgically, electrodes positioned near incision-site nerves manage acute-on-chronic pain without systemic opioids, accelerating rehabilitation. A single electrode can serve dual duty, treating both neuropathic and nociceptive components in complex surgical scars. Each application requires precise anatomical targeting and patient-specific programming for sustained relief.
Advancements in ultrasound-guided placement techniques
Recent developments in ultrasound-guided placement techniques have dramatically improved the precision of peripheral nerve stimulation for localized discomfort. Real-time visualization now allows clinicians to navigate around critical neurovascular structures, reducing inadvertent nerve injury and procedural pain. Dynamic needle tracking enables precise tip-to-nerve proximity adjustments, optimizing electrode position for effective current spread. Doppler integration confirms vascular avoidance during lead insertion, significantly lowering hematoma risks. These advancements directly translate to more consistent paresthesia coverage and faster onset of relief for the patient, making targeted placement both safer and more reproducible in clinical practice.
Ultrasound-guided placement techniques enhance safety, accuracy, and consistency in targeting nerve structures for localized discomfort relief.
Non-Invasive Approaches: TENS and rTMS
For chronic pain management, non-invasive neurostimulation primarily uses TENS and rTMS to modulate neural activity without surgery. TENS delivers low-voltage electrical pulses through surface electrodes to activate descending inhibitory pathways, offering patient-controlled relief for localized musculoskeletal or neuropathic pain, though efficacy depends on electrode placement and stimulation parameters. rTMS applies magnetic pulses to specific cortical regions, like the motor cortex, to normalize maladaptive pain circuits. It requires multiple clinic sessions but can provide sustained analgesia for conditions like fibromyalgia or central pain syndromes that resist medication.
A key insight is that TENS targets peripheral nerve gates, while rTMS aims to recalibrate central pain processing.
Both require proper patient selection and realistic expectations regarding response latency.
Transcutaneous electrical nerve stimulation for home use
For chronic pain management, home TENS units offer a practical, self-administered tool by delivering low-voltage electrical pulses through adhesive electrodes placed on the skin. You control the intensity, frequency, and pulse width to target specific pain sites, typically during 20–30 minute sessions. Portable and battery-operated, these devices allow you to interrupt pain signals before they reach the brain. Standard electrode placements follow nerve pathways or trigger points, enabling you to adjust treatment for flare-ups without clinic visits. A gate control mechanism is often cited for its analgesic effect, providing a drug-free alternative for conditions like osteoarthritis or back pain.
| Aspect | Home TENS Use |
|---|---|
| Electrode placement | Directly over pain or along nerve pathways |
| Session duration | 20–30 minutes, multiple times daily |
| Adjustability | Frequency (1–150 Hz) and intensity (mA) |
| Primary mechanism | Gate control theory |
Repetitive transcranial magnetic stimulation in clinical settings
In clinical settings, repetitive transcranial magnetic stimulation (rTMS) for chronic pain management is delivered via a coil placed over the motor cortex, applying rapid magnetic pulses to modulate pain-processing circuits. Sessions typically run 20–40 minutes, often requiring 10–30 daily treatments for sustained relief. Patients remain awake and seated, experiencing only a mild tapping sensation; no sedation is needed. Efficacy is assessed individually, with responders reporting 30–50% pain reduction, particularly for neuropathic conditions. A key marker is cortical excitability, which guides dosage adjustments. What is the success rate for rTMS in clinical pain trials? Approximately 40–60% of patients achieve clinically meaningful pain relief, though results vary by diagnosis and protocol adherence.
Comparing efficacy and safety profiles across modalities
Direct comparisons of efficacy and safety across non-invasive modalities reveal distinct trade-offs for chronic pain management. TENS offers immediate, user-controlled relief with minimal systemic risks, primarily skin irritation, but its efficacy often plateaus due to habituation. Conversely, rTMS demonstrates superior and longer-lasting analgesic effects, particularly for neuropathic pain, yet carries a higher burden of transient headaches and a rare seizure risk. Clinical decisions pivot on this balance: TENS suits at-home, on-demand use with a favorable safety floor, while rTMS demands clinical oversight for greater and more durable pain reduction.
Compared directly, TENS provides safer, self-managed acute pain relief with lower efficacy, while rTMS delivers superior, sustained analgesia at a higher safety risk.
Emerging Technologies: Closed-Loop and Adaptive Systems
Closed-loop neurostimulation transforms chronic pain management by continuously sensing neural signals and adjusting stimulation in real time. Unlike open-loop devices that deliver fixed pulses, adaptive systems detect pathological activity—such as aberrant dorsal horn oscillations—and modulate parameters instantly. This dynamic responsiveness prevents both undertreatment and uncomfortable overstimulation, as the system learns each patient’s evolving pain patterns. For example, a spinal cord stimulator might ramp up output during movement-triggered flares and scale back at rest, preserving therapeutic effect without disrupting daily life. Users experience sustained relief and fewer side effects because the technology responds to their body’s current state, not a pre-set schedule. These systems also minimize frequent reprogramming visits, shifting control to the device’s embedded intelligence.
Responsive neurostimulation that adjusts in real time
Real-time responsive neurostimulation for chronic pain works by continuously monitoring your brain’s specific pain signatures and delivering micro-bursts of stimulation only when abnormal activity is detected. Unlike traditional open-loop devices that provide constant, unvarying pulses, this adaptive system instantly adjusts intensity and location based on your shifting neural signals. The result is significantly fewer false sensations and better dynamic pain relief during movement or rest. How does real-time adjustment improve daily function? By matching stimulation to your moment-by-moment pain state, it prevents over-stimulation numbness and under-stimulation breakthrough pain, allowing you to move, sleep, and exercise without abrupt symptom return.
Integrating wearable sensors with AI-driven algorithms
Integrating wearable sensors with AI-driven algorithms enables real-time physiological monitoring to dynamically adjust neurostimulation parameters for chronic pain. Electromyography and skin conductance sensors detect pain-correlated stress responses, while AI analyzes these patterns to modulate stimulation intensity or frequency without patient intervention. This closed-loop approach reduces energy waste and prevents overstimulation, as algorithms learn individual pain thresholds through iterative feedback. Adaptive neurostimulation calibration ensures that wearable sensors can distinguish between movement artifacts and true nociceptive signals, refining algorithm accuracy over weeks of use. Q: How do wearable sensors validate AI adjustments in real time? A: They cross-reference instantaneous biometric data—like heart rate variability and muscle tension—against the AI’s predicted pain state, triggering immediate recalibration if the algorithm’s output fails to lower the measured distress markers.
Potential for personalized pain treatment protocols
Closed-loop neurostimulation enables real-time adaptive pain protocols by continuously analyzing neural or physiological biomarkers. These systems titrate stimulation parameters—such as amplitude, frequency, and pulse width—to match fluctuating pain intensity throughout the day. A patient with complex regional pain syndrome, for example, could receive lower baseline stimulation during rest and precisely targeted bursts during movement-triggered flares, all without manual adjustment. This dynamic personalization minimizes overstimulation and paresthesia, while maximizing relief for specific pain types like neuropathic or nociceptive components. The protocol inherently learns individual response patterns, refining its algorithm to prioritize the most effective waveform for that person’s neural signature.
Personalized pain treatment protocols use closed-loop feedback to dynamically self-adjust stimulation, delivering precisely timed relief tailored to an individual’s fluctuating pain patterns and neural responses.
Who Benefits Most From These Therapies?
Patients with neuropathic pain from conditions like failed back surgery syndrome or complex regional pain syndrome benefit most from neurostimulation, specifically spinal cord stimulation. Individuals who have not achieved adequate relief from conservative treatments or surgery, and who are psychologically stable, are ideal candidates. The therapy works best when a successful trial period demonstrates at least a 50% reduction in pain intensity. Those with nociceptive pain, such as from arthritis or acute injury, generally do not respond well. Patients willing to commit to device management and follow-up programming sessions see the greatest long-term benefits.
Patient profiles: neuropathic, nociceptive, and mixed pain types
Patients with predominantly neuropathic pain, such as diabetic neuropathy or postherpetic neuralgia, typically respond best to spinal cord stimulation because the therapy directly modulates aberrant nerve signaling. In contrast, those with nociceptive pain from acute tissue damage or osteoarthritis derive limited benefit, as this pain type involves peripheral input less accessible to central neurostimulation. Mixed pain profiles—common in failed back surgery syndrome—often require multimodal programming, where targeted stimulation addresses the neuropathic component (e.g., limb burning) while residual nociceptive input (e.g., axial mechanical pain) may persist.
Q: Why is neuropathic pain more responsive to neurostimulation than nociceptive pain?
Neurostimulation directly disrupts abnormal electrical impulses in damaged nerves, which are characteristic of neuropathic pain, whereas nociceptive pain involves inflammation or mechanical pressure that stimulation cannot fully reverse.
Psychological and functional outcomes in clinical trials
Clinical trials assessing neurostimulation for chronic pain increasingly prioritize psychological and functional outcomes in clinical trials beyond mere pain reduction. These studies typically measure changes in catastrophizing, depression, and anxiety using validated scales like the Pain Catastrophizing Scale and Hospital Anxiety and Depression Scale. Functional outcomes are evaluated through objective metrics such as gait analysis, sleep quality indices, and return-to-work rates. The sequence often follows:
- Baseline assessment of pain-related distress and disability.
- Post-implantation evaluation of mood and daily activity tolerance at 3 and 6 months.
- Composite scoring to identify responders who achieve both meaningful pain relief and functional improvement.
Trials consistently show that patients with higher baseline psychological distress derive greater functional gains, while those with minimal mood disturbance show smaller improvements in daily living scores.
Limitations: contraindications, infection risks, and device failure
Contraindications for neurostimulation include active sepsis, coagulopathy, or untreated addiction, as these conditions elevate procedural and post-implant risks. Infection risks are significant, with perisurgical site infections or deeper pocket infections often requiring device explantation. Device failure, such as lead migration, fracture, or battery depletion, can abruptly halt pain relief, necessitating revision surgery. Even with rigorous sterile technique, biofilm formation on implanted components remains a persistent infection challenge. These factors directly limit candidacy; for example, immunocompromised patients face amplified infection probabilities that outweigh potential benefits. Practical device management hinges on anticipating these failure modes.
Limitations in neurostimulation center on strict contraindications (e.g., coagulopathy, active infection), inherent infection risks (site or implant-level), and device failure (lead issues, power source exhaustion) that can undermine therapeutic continuity.
Combining Neurostimulation With Other Treatments
When neurostimulation alone didn’t fully quiet Sarah’s nerve pain, her clinician wove it into a broader plan. She began physical therapy each morning, the stimulation’s paresthesia masking the sharp spikes that usually stopped her after two stretches. On days when the stimulation provided around 70% relief, she could engage in manual therapy without guarding. Her psychologist taught her to use the device’s intensity settings as a cue for paced breathing during flare-ups. Medication was reduced gradually—the neurostimulation allowed gabapentin to drop from 900 mg to 300 mg without withdrawal. The real shift came when she stopped fighting the pain and started collaborating with the technology’s rhythm. Now, the implant is not a cure but a lever—turning the volume on pain down enough for movement, sleep, and social connection to take hold.
Synergy with physical therapy and cognitive behavioral approaches
Integrating neurostimulation with physical therapy and cognitive behavioral approaches creates a multimodal treatment synergy that addresses both peripheral and central pain mechanisms. Physical therapy enhances neurostimulation outcomes by improving musculoskeletal conditioning, biomechanics, and activity tolerance, which reduces reliance on stimulation intensity. Concurrent cognitive behavioral therapy targets maladaptive pain beliefs, catastrophizing, and fear-avoidance behaviors, thereby lowering central sensitization and improving adherence to both stimulation and exercise protocols. This combined approach sequentially desensitizes the nervous system during movement and reframes pain perception, leading to greater functional gains than either modality alone. Q: How does cognitive behavioral therapy directly complement neurostimulation? A: It reduces hypervigilance and emotional distress, which lowers the dorsal horn’s excitability, allowing lower stimulation amplitudes to produce effective pain relief during physical therapy sessions.
Reducing opioid dependence through electrical modulation
Electrical modulation directly reduces opioid dependence by providing a non-pharmacological analgesic alternative that targets central pain pathways. Spinal cord stimulation, for instance, can attenuate pain signals, allowing clinicians to taper opioid dosages without triggering withdrawal or breakthrough pain. This substitution works best when neurostimulation parameters are titrated against the patient’s existing opioid level, avoiding abrupt cessation that could destabilize pain control. Over time, patients who maintain consistent electrical modulation often report fewer cravings and reduced need for rescue medication. The key mechanism involves activating descending inhibitory pathways, which diminish the brain’s reliance on exogenous opioids for pain relief. Electrical modulation for opioid reduction thus offers a sustainable, dose-titratable bridge toward lower dependence.
Multidisciplinary care models for comprehensive pain management
Multidisciplinary care models for comprehensive pain management integrate neurostimulation with physical therapy, behavioral health, and medication optimization to target the biopsychosocial dimensions of chronic pain. In this framework, neurostimulation is not a standalone intervention but a component within a coordinated regimen; physical therapists adjust exercise protocols based on stimulation parameters, while psychologists teach cognitive-behavioral techniques to mitigate pain catastrophizing. This synergy reduces opioid reliance and enhances functional outcomes by addressing nociceptive, neuropathic, and affective drivers simultaneously. Coordinated care pathways ensure that titration of stimulation settings aligns with physiotherapy progression and psychological readiness, preventing over-reliance on the device alone. The table below outlines how each discipline modifies its protocol relative to neurostimulation:
| Discipline | Integration with Neurostimulation |
|---|---|
| Physical Therapy | Adjusts movement dosage to match stimulation-induced analgesia windows |
| Behavioral Health | Teaches coping strategies for residual pain during stimulation titration |
| Pain Medicine | Weans concurrent medications as stimulation efficacy stabilizes |
