Key Takeaways
- Chronic pain is pain lasting over three months; NICE distinguishes chronic primary pain (no underlying cause fully explains it) from chronic secondary pain (linked to another condition), and guidance differs by diagnosis.
- Set specific, functional goals such as walking 20 minutes or sleeping through the night, rather than just 'less pain,' so both clinician and patient can judge whether a device is helping.
- NICE advises against offering TENS for chronic primary pain and for low back pain, so review condition-specific guidance and use only time-limited, monitored trials with defined stopping criteria.
- Screen for safety before using TENS, including implanted electronic devices, pregnancy, impaired sensation, and skin problems, and treat electrotherapy as one adjunct within broader care like exercise and psychological approaches.
Chronic pain affects millions of adults, and clinics are often the first place patients turn for answers. According to the CDC, 24.3% of U.S. adults reported chronic pain in 2023, and 8.5% lived with high-impact chronic pain that frequently limited work or daily life. For chiropractors, physical therapists, and auto accident injury clinics, this means a steady stream of patients who need more than a single treatment visit.
Learning how to manage chronic pain takes a plan, not a single device. Electrotherapy, including TENS (transcutaneous electrical nerve stimulation), can be one tool within that plan. It is not a cure, and evidence varies by condition. This guide gives clinics nine practical, evidence-aware strategies for using electrotherapy responsibly as part of broader pain care.
What Counts as Chronic Pain?
Chronic pain is generally pain that persists or returns for more than three months. NICE separates it into two groups. Chronic primary pain has no underlying condition that fully explains the pain or its impact. Chronic secondary pain is linked to another condition, such as arthritis or a prior injury. Both types can occur together.
This distinction matters for clinics. Guideline advice differs by diagnosis, so one rule does not fit every patient. The CDC also notes that women reported higher rates of chronic pain (25.4%) than men (23.2%) in 2023, and about 34.9% of adults with chronic pain had high-impact chronic pain. Careful assessment comes first.
9 Ways to Manage Chronic Pain With Electrotherapy
1. Start With a Person-Centered Assessment
Good pain care begins with listening. NICE recommends a person-centered assessment and care plan that looks at function, sleep, mood, and activity, not pain intensity alone. A patient who sleeps poorly and avoids movement needs a different plan than one with a single flare-up.
Before suggesting any device, clinics should document the following:
- Pain location, duration, and triggers
- Impact on work, sleep, and daily tasks
- Prior treatments and how the patient responded
- Safety concerns, such as implanted devices or skin problems
2. Set Clear, Functional Goals
"Less pain" is a weak goal. Better goals are specific and measurable, such as walking 20 minutes without stopping or sleeping through the night. Functional goals give both the clinician and patient a fair way to judge whether a device is helping.
When goals are written down, the patient also stays engaged. Our guide on how to determine if a TENS unit really works offers useful ways to track results.
3. Understand What TENS Can and Cannot Do
TENS delivers low-voltage electrical pulses through skin electrodes. The goal is a comfortable tingling sensation. Some people report temporary symptom relief, but response varies widely. TENS does not find or treat the cause of pain.
The Cleveland Clinic describes TENS as a non-invasive option that works for some patients and not others. Honest expectations build trust. Clinics can read more in 15 Facts: TENS Units - Do They Actually Work?
4. Know What the Guidelines Say
Evidence should never be generalized across diagnoses or devices. NICE advises against offering TENS, ultrasound, or interferential therapy for chronic primary pain. Its review found no clinically important difference from sham TENS or usual care at under three months, and no longer-term evidence was identified. NICE also advises against TENS, PENS, and interferential therapy for low back pain with or without sciatica.
Clinicians should review condition-specific guidance and discuss uncertainty with patients. Evidence in some settings is limited, with small studies and unclear benefit beyond three months. A transparent conversation protects both the patient and the practice. You can also review how to manage lower back pain with electrotherapy in 2026 for a closer look at one common condition.
5. Use Time-Limited, Monitored Trials
If you and the patient choose to try a TENS device, agree on a time-limited trial with a meaningful goal, such as better activity or sleep. Review progress at set intervals. Stop the trial if the device does not help or if it causes discomfort or skin irritation.
A simple trial process looks like this:
- Confirm the device is suitable for the patient.
- Define the goal and the trial length.
- Teach safe use, including electrode placement and intensity.
- Record function and sleep at each follow-up.
- Continue only if the goal is being met.
6. Teach Safe Placement and Intensity
Safe use protects patients and reduces complaints. Electrodes belong on clean, intact skin. Intensity should feel strong but comfortable, never painful. Patients should follow the device instructions closely.
Two resources help here: how to set your TENS unit to the right intensity level and how to choose and use TENS electrodes safely in 2026. Clinics can hand these concepts to patients as plain-language teaching points.
7. Screen for Safety Concerns
Not every patient should use TENS. Clinicians should seek advice about suitability for patients with implanted electronic devices, pregnancy, impaired sensation, or skin problems. When in doubt, hold off and consult the treating clinician.
The table below summarizes common screening points.
Patient Factor | Why It Matters | Suggested Action |
|---|---|---|
Implanted electronic device | Possible interference with device function | Seek clinical advice before use |
Pregnancy | Safety data is limited | Consult the treating clinician |
Impaired sensation | Patient may not feel overstimulation | Use caution or avoid |
Skin irritation or wounds | Electrodes may worsen the problem | Avoid affected areas; monitor skin |

8. Combine Electrotherapy With Broader Care
Electrotherapy works best as an adjunct, not a substitute for assessment or other treatment. Depending on the diagnosis, a care plan may include supported exercise, psychological approaches, treatment of an underlying condition, and appropriate medicines. These choices should be made with a qualified healthcare professional.
The CDC lists nonopioid therapies for pain management as an important part of clinical care. Chiropractic and physical therapy clinics can pair in-office care with home tools. Related reading includes 9 pillars of professional pain management in 2026 and 6 ways TENS units support chronic pain management.
9. Extend Care Into the Patient's Daily Life
Relief gained in the office can fade by evening. Home-use tools help patients carry progress into everyday life. This is especially valuable for auto accident injury clinics treating whiplash and soft tissue complaints, where daily symptom control supports recovery.

How the Evidence Differs by Situation
Because guidance varies, a quick comparison helps clinics set expectations before recommending anything.
Situation | What Guidelines Indicate | Clinical Takeaway |
|---|---|---|
Chronic primary pain | NICE advises against offering TENS | Prioritize exercise and psychological approaches |
Low back pain, with or without sciatica | NICE advises against TENS, PENS, and interferential therapy | Review condition-specific guidance first |
Other diagnoses | Evidence varies by condition and device | Use a short, monitored trial with clear goals |
This table is a starting point, not a rulebook. Clinics should always consult current, condition-specific guidance.
Practical Tips for Clinics Building a Pain Program
A repeatable process keeps care consistent across providers. Consider these steps when building or refining a chronic pain program:
- Create a standard intake form that captures function, sleep, and mood.
- Train staff to explain what TENS can and cannot do.
- Keep a written trial plan for every device recommendation.
- Schedule follow-ups to review goals and stop ineffective trials.
These habits protect patients and improve outcomes. For program design ideas, see how to build an effective medical pain management program. The National Institutes of Health has also reported on high rates of persistent chronic pain among U.S. adults, which underscores the need for structured clinic programs.
Why Supplier Choice Matters
The device itself is only part of the picture. A reliable supplier makes it easier to keep electrodes, lead wires, and replacement parts available. That keeps patient trials running smoothly and avoids gaps in care.
Liberty Medical Solutions is a Tampa, Florida-based nationwide supplier built around a provider-first approach. The company works with chiropractic and physical therapy clinics and accepts Commercial PPO/POS plans with out-of-network benefits, Workers' Compensation, Auto Accident, and Third-Party Liability claims. Coverage is never guaranteed, so clinics should verify details for each patient. To compare supplier qualities, read 7 traits of a trustworthy electrotherapy medical supply company.
Conclusion
Managing chronic pain well means building a plan around the whole person. Electrotherapy can play a supporting role, but only when it is matched to the right patient, tested with clear goals, and stopped if it does not help. Honest conversations about evidence, strong safety screening, and combined care give patients the best chance at meaningful progress in 2026.
