Lin Health vs Sword Health: How the Two Programs Compare

If you live with chronic pain and your employer or health plan offers a digital pain program, two names you may have seen are Lin Health and Sword Health. Both deliver care virtually. Both are typically covered by insurance or an employer benefit. But the two programs are built around very different ideas about what drives chronic pain and how to address it.

This article is a side-by-side look at what each program does, who it tends to fit, and the evidence base each one draws on. It is not a head-to-head efficacy ranking. Any decision about how to manage chronic pain should involve a clinician who knows your medical history.

Key Takeaways

• Roughly 1 in 4 US adults lives with chronic pain, and the CDC's 2022 prescribing guideline calls nonopioid therapies (both nonpharmacologic and nonopioid pharmacologic) preferred for subacute and chronic pain.
• Lin Health is a coach-led behavioral pain program for chronic pain and persistent symptoms (migraine, IBS, long COVID, tinnitus, POTS), delivered through a recovery coach and an app, with insurance coverage in CO, TX, FL, CA, and NY.
• Sword Health is a virtual physical-therapy program for musculoskeletal pain (back, neck, joints) and other conditions, delivered through licensed clinicians and an AI care specialist, typically accessed as an employer benefit.
• The two programs target different contributors to chronic pain: Sword's evidence base sits in exercise for chronic back pain and similar musculoskeletal conditions; Lin Health's sits in behavioral therapies for nociplastic and centralized chronic pain.
• They are not interchangeable. Choosing between them depends on the kind of pain you have, what you have already tried, and what kind of support you are looking for.

Two Different Approaches to Chronic Pain

After about three months, pain often involves changes in how the nervous system processes signals, not just ongoing tissue damage at the original injury site. The International Association for the Study of Pain calls this pattern nociplastic pain when it appears without a clear lesion or pathology to explain it. Many people with chronic pain have a mix of contributors: a movement or deconditioning component, a centralized or nociplastic component, and sometimes a structural component as well.

Lin Health and Sword Health target different pieces of that picture.

Sword Health is built around movement. Its chronic-pain program (called Thrive) delivers digital physical therapy through licensed clinicians and an AI care specialist, the same general modality with substantial evidence for chronic back pain and a long history of use across other musculoskeletal conditions.

Lin Health is built around the nervous system. The program uses behavioral modalities (CBT, ACT, AET) delivered by a recovery coach to address the fear of movement, the emotional loops, and the learned patterns that can keep a pain alarm firing long after the original tissue has healed. This kind of approach has evidence for adult chronic pain and a growing evidence base specifically in chronic primary back pain and older veterans with chronic pain.

Both approaches sit comfortably inside what the CDC's 2022 prescribing guideline calls "nonopioid therapies preferred for subacute and chronic pain." They are different tools for different jobs.

Lin Health at a Glance

What it is

Lin Health is a digital behavioral program for chronic pain and persistent symptoms. The program is built on a brain-first model of how chronic pain works: after the body has healed, a pain alarm can stay stuck in the nervous system and continue firing without ongoing tissue damage. Lin Health's role is to help retrain that alarm.

How it works

A patient signs up on the Lin Health website and gets a same-day callback to check insurance eligibility. After enrollment, the patient is matched with a trained recovery coach and works through structured modules combining live calls, between-session messaging, and an app with learning and practice materials.

Modalities used

The program's clinical approach draws on cognitive behavioral therapy, acceptance and commitment therapy, and emotional awareness and expression therapy, along with other behavioral modalities adapted specifically for chronic pain and persistent symptoms. The clinical philosophy is informed by the work of researchers in pain reprocessing therapy and the field of nociplastic pain.

Conditions addressed

Lin Health works with adults living with:

• Chronic low back pain, neck pain, and shoulder pain
• Fibromyalgia
• Chronic migraine and other persistent headache conditions
• IBS, long COVID, tinnitus, and POTS
• Other persistent-symptom conditions where the nervous system plays a central role

Cost and insurance

Lin Health is in-network with major insurance plans across Colorado, Texas, Florida, California, and New York, with additional coverage in other states. Most enrolled patients pay zero out of pocket.

Wait times and onboarding

Patients who sign up typically receive a callback the same day, and the path from signup to first coach session is short relative to traditional behavioral-health intake processes.

Who it tends to fit

• Adults whose pain has persisted beyond what imaging or examination explains
• Patients who have tried physical therapy, medication, injections, or surgery without lasting relief
• Patients with chronic conditions that physical therapy does not address (migraine, IBS, long COVID, tinnitus, POTS)
• Patients drawn to a brain-first model of pain (often readers of work by Drs. John Sarno, Alan Gordon, or Howard Schubiner)

Sword Health at a Glance

What it is

Sword Health is a digital health company that describes itself publicly as an "AI Care platform" for several condition areas including muscle and joint pain. Its model pairs a licensed clinician with what Sword calls an "AI Care Specialist."

How it works

According to Sword's public materials, the program is delivered virtually and combines licensed clinicians with an AI care specialist that supports personalization and accessibility.

Programs

Sword publicly lists multiple programs. The one most relevant to a chronic-pain comparison is Thrive, described by Sword as "AI Care for pain through digital physical therapy that pairs AI and licensed clinicians." Other programs include Bloom (women's health), Pulse (cardiometabolic), Mind (psychologist-led mental health care), and Predict (an AI engine focused on detecting members at risk for avoidable musculoskeletal and pelvic surgery).

Conditions addressed

The Thrive program is positioned for muscle and joint pain. Sword's other programs address other clinical areas, but they fall outside the chronic-pain scope of this article.

Access

Sword is most commonly accessed through an employer benefit or a health plan. Sword also describes a direct-to-consumer enrollment path on its website.

Who it tends to fit

Based on Sword's public positioning, Thrive is built for patients whose pain is clearly tied to a specific muscle or joint region and who are likely to benefit from a guided exercise and physical-therapy approach.

Side-by-Side: The Short Version

Lin Health is a coach-led behavioral program for chronic pain and persistent symptoms, delivered with insurance coverage in select US states.

Sword Health is a virtual physical-therapy program for musculoskeletal pain and other condition areas, delivered through licensed clinicians and an AI care specialist, typically as an employer benefit.

The two programs are not interchangeable. They target different contributors to chronic pain, draw on different evidence bases, and tend to fit different patient situations.

The Evidence Each Program Draws On

The evidence base behind virtual physical therapy and the evidence base behind behavioral pain therapy are distinct. Each program sits in a different research tradition, and the studies that support one approach do not automatically transfer to the other.

What supports an exercise-based approach for musculoskeletal pain

Exercise therapy has a long evidence base for many musculoskeletal conditions. A 2021 Cochrane review of 249 trials with more than 24,000 participants found that exercise improves chronic back pain and function for adults with chronic non-specific low back pain compared with other conservative treatments, with the strongest signal versus education alone or non-exercise physical therapy.

The American College of Physicians' 2017 chronic low back pain guideline recommends nonpharmacologic first-line treatment, including exercise, multidisciplinary rehabilitation, mindfulness-based stress reduction, and cognitive behavioral therapy, for adults with chronic low back pain.

This is the research universe that supports a Sword-style virtual physical therapy program for musculoskeletal pain.

What supports a behavioral approach for chronic and nociplastic pain

A different set of studies supports the behavioral approach Lin Health uses. A 2020 Cochrane review of psychological therapies for chronic pain in adults (excluding headache) found that CBT helps adult chronic pain, with small or very small beneficial effects on pain, disability, and distress observed both immediately after treatment and at follow-up.

A 2022 randomized trial in adults with chronic primary back pain found that PRT left 66 percent pain-free or nearly pain-free at the end of treatment, compared with 20 percent in an open-label placebo group and 10 percent in usual care. A 2025 five-year follow-up of the same trial reported that more than half of PRT participants remained nearly or completely pain-free five years after treatment.

A 2024 trial in older US military veterans with chronic musculoskeletal pain found that EAET outperformed CBT for pain, with 63 percent of EAET participants achieving a clinically meaningful pain reduction at week 10 compared with 17 percent in the CBT group.

These trials studied specific populations (chronic primary back pain in adults aged 21 to 70; older US veterans with chronic musculoskeletal pain) and their findings should be read inside those scopes. They are also the research tradition Lin Health's approach is built on, and they help explain why a behavioral program can produce meaningful change in pain that has not responded to physical or medical approaches alone.

No peer-reviewed trial has compared Lin Health and Sword Health directly. Each program's evidence base is its own.

Which Program Fits Your Situation

The honest way to choose between Lin Health and Sword Health is to start with your own pain rather than the programs.

Sword Health tends to fit when:

• Your pain is clearly tied to a specific muscle, joint, or movement
• You have a recent or recurring musculoskeletal issue (back, neck, shoulder, knee, hip)
• Imaging or exam findings line up with where you feel pain
• You have not yet tried structured physical therapy or want a guided exercise program
• You learn best by doing exercises and getting feedback on your movement

Lin Health tends to fit when:

• Your pain has persisted for months or years beyond what imaging explains
• Your pain has spread to multiple areas, or moves around your body
• You have already tried physical therapy, medication, injections, or surgery without lasting relief
• You have a persistent symptom that physical therapy does not address (migraine, IBS, long COVID, tinnitus, POTS)
• You suspect a central nervous-system role in keeping your pain going
• You are drawn to a brain-first model of chronic pain and want a recovery coach to walk you through it

If you are not sure which describes your situation, the most useful next step is a conversation with a clinician who can look at your full history.

How Lin Health Helps With Chronic Pain

Lin Health was built specifically for the kind of pain that does not resolve on its own and does not fully respond to physical or pharmacological treatment. The program's approach is based on a growing body of pain-neuroscience research that shows how chronic pain can become a learned signal in the brain and nervous system, separate from any ongoing tissue damage.

In the program, a trained recovery coach works with you weekly through a protocolized set of modules drawn from cognitive behavioral therapy, acceptance and commitment therapy, emotional awareness and expression therapy, and related modalities. You also get between-session messaging access to your coach and an app with structured learning and practice materials.

Lin Health is in-network with major insurance plans across Colorado, Texas, Florida, California, and New York, with additional coverage in other states. Most enrolled patients pay zero out of pocket. The onboarding path is short: a same-day callback after you sign up, an eligibility check, and a first appointment with a physician who enrolls you into the program.

If you have been living with chronic pain that has not responded to the standard treatment path, or you have a persistent symptom like chronic migraine, IBS, long COVID, tinnitus, or POTS that physical therapy does not address, a behavioral pain program may be worth exploring as part of a coordinated care plan.

FAQ

Is Lin Health a replacement for physical therapy?

No. Lin Health is a behavioral pain program, not a physical-therapy program. It does not prescribe exercises or provide hands-on care. Many patients have already tried physical therapy before coming to Lin Health, and some continue working with a physical therapist alongside the program. Whether either approach is right for you depends on what is driving your pain, which is a conversation worth having with a clinician.

Is Sword Health a replacement for behavioral pain therapy?

Sword Health publicly describes its Thrive program as digital physical therapy for muscle and joint pain. It is built around guided exercise and licensed clinicians, not behavioral pain modalities. If your pain has a strong centralized or nociplastic component, a virtual physical-therapy program may not fully address it.

Does Lin Health treat back pain?

Yes. Chronic low back pain is one of the most common conditions Lin Health works with. The behavioral approach is most useful when back pain has persisted beyond what imaging explains, has spread to other regions, or has not responded to physical therapy and medication alone.

Does Lin Health work with conditions other than musculoskeletal pain?

Yes. Lin Health works with adults living with chronic migraine, IBS, long COVID, tinnitus, POTS, and other persistent-symptom conditions where the nervous system plays a central role. These conditions are generally outside the scope of a virtual physical-therapy program.

Is Lin Health covered by insurance?

Lin Health is in-network with major insurance plans across Colorado, Texas, Florida, California, and New York, with additional coverage in other states. After you sign up, a Lin Health team member will check your specific eligibility on a same-day callback. Most enrolled patients pay zero out of pocket.

How do I know which program is right for me?

Start with the pain you have and what you have already tried. If your pain is tied to a specific joint and improves with exercise, a virtual physical-therapy program may be a good fit. If your pain has persisted beyond what imaging explains, has spread, or has not responded to physical therapy and medication, a behavioral pain program may be worth exploring. The most useful next step is a conversation with a clinician who knows your history.
