The Viscerosomatic Reflex: When Your Organs Talk to Your Muscles

Have you ever noticed back tension when you’re stressed, or neck stiffness that seems to flare up when you’re not feeling well? While it may seem coincidental, there’s a fascinating neurological explanation behind these patterns: the viscerosomatic reflex.


Understanding the viscerosomatic reflex helps explain why internal organ dysfunction can show up as muscle tension, pain, or restricted movement—and why chiropractic and massage care can play a valuable role in managing these patterns. Let’s break it down.

What Is the Viscerosomatic Reflex?

The viscerosomatic reflex is a neurological phenomenon where irritation or dysfunction in an internal organ (viscera) causes a response in the musculoskeletal system (soma). This response often presents as muscle tightness, tenderness, altered joint motion, or postural changes.


This happens because internal organs and certain muscles share common spinal nerve pathways. When an organ sends distress signals to the spinal cord, the nervous system may “spill over” into nearby muscles, causing them to contract or become hypersensitive—even though the muscle itself isn’t injured.


In short:

Organ stress → nervous system response → muscle and joint changes

How the Nervous System Connects It All

To understand the viscerosomatic reflex, it helps to look at the anatomy of the nervous system.

  • Internal organs send sensory information to the spinal cord through visceral afferent nerves
  • Muscles, joints, and skin send sensory input through somatic afferent nerves
  • These nerve fibers often enter the spinal cord at the same spinal levels

When the spinal cord receives repeated or intense signals from an organ, it can increase motor output to muscles at that same level. Over time, this may result in:

  • Chronic muscle tension
  • Trigger points
  • Reduced joint mobility
  • Localized pain or discomfort

This is not a conscious process—it’s an automatic protective reflex controlled by the nervous system.

Common Examples of the Viscerosomatic Reflex

The viscerosomatic reflex follows predictable patterns known as segmental relationships. Here are some common examples seen in clinical settings:

1. Heart → Upper Back and Left Shoulder

Cardiac irritation is classically associated with discomfort in:

  • Upper thoracic spine (T1–T5)
  • Left shoulder and arm
  • Chest wall muscles

While this pattern is most often discussed in medical emergencies, mild or chronic irritation can also contribute to persistent upper back tension.

2. Stomach → Mid-Back (Left Side)

Stomach irritation may refer to:

  • Mid-thoracic spine (T5–T9)
  • Left-sided paraspinal muscle tightness

Patients may notice stiffness or aching between the shoulder blades, especially during periods of digestive upset or stress.

3. Liver and Gallbladder → Right Shoulder and Mid-Back

The liver and gallbladder are commonly associated with:

  • Right mid-back tension
  • Right shoulder or upper trapezius tightness

This pattern can mimic muscular strain and may persist despite stretching alone.

4. Kidneys → Lower Back

Kidney-related irritation often refers to:

  • Lower thoracic and upper lumbar spine (T10–L2)
  • Deep, aching low back discomfort

This pain may feel different from mechanical low back pain and may not change significantly with movement.

5. Intestines → Low Back and Pelvis

Digestive organs can influence:

  • Lumbar spine
  • Pelvic musculature
  • Hip flexors

This connection helps explain why bloating, constipation, or GI distress can coincide with low back stiffness.

Why These Reflexes Can Become Chronic

In acute situations, viscerosomatic reflexes are protective. However, when organ stress becomes chronic, the nervous system may remain in a heightened state.


Over time, this can lead to:

  • Persistent muscle guarding
  • Joint fixation
  • Reduced spinal mobility
  • Heightened pain sensitivity

Even after the original organ irritation improves, the musculoskeletal pattern may linger—essentially becoming “learned” by the nervous system.


This is where conservative care can make a meaningful difference.

How Chiropractic and Massage Care Can Help

While chiropractic and massage therapy do not treat internal organ disease, they can address the <strong>musculoskeletal consequences</strong> of viscerosomatic reflexes.

Chiropractic Care

Chiropractic adjustments focus on restoring normal joint motion and reducing abnormal nervous system signaling. When spinal segments associated with viscerosomatic reflexes are restricted, adjustments may help:

  • Improve joint mobility
  • Reduce reflexive muscle guarding
  • Normalize neurological input
  • Improve movement efficiency

By addressing spinal dysfunction at specific segmental levels, chiropractors aim to reduce unnecessary nervous system stress.

Massage Therapy

Massage therapy is especially effective for calming the somatic side of the reflex.


Benefits may include:

  • Reducing muscle hypertonicity
  • Improving local circulation
  • Decreasing trigger point sensitivity
  • Supporting parasympathetic (rest-and-digest) nervous system activity

Techniques such as deep tissue work, myofascial release, and trigger point therapy can help break the cycle of chronic muscle tension driven by reflexive pathways.

The Stress Connection

Stress deserves special attention when discussing viscerosomatic reflexes.


Chronic stress increases sympathetic nervous system activity, which:

  • Alters digestion
  • Changes breathing patterns
  • Increases muscle tone
  • Sensitizes pain pathways

This creates a feedback loop where stress affects organ function, organ signals affect muscles, and muscle tension reinforces stress. Chiropractic and massage care can help interrupt this loop by improving movement and promoting nervous system balance.

When to Seek Additional Medical Care

It’s important to note that unexplained pain—especially when accompanied by symptoms such as fever, unexplained weight loss, severe fatigue, or digestive changes—should always be evaluated by a medical provider.


Chiropractic and massage therapy work best as part of a <strong>collaborative, patient-centered approach,</strong> supporting musculoskeletal health alongside appropriate medical care.

Bringing It All Together

The viscerosomatic reflex highlights just how interconnected the body truly is. Pain doesn’t always originate where you feel it, and tight muscles aren’t always caused by poor posture or overuse alone.


By understanding these neurological connections, chiropractors and massage therapists can take a more informed approach—looking beyond isolated symptoms and addressing patterns that may be driven by the nervous system itself.


If you’re dealing with stubborn muscle tension, recurring spinal stiffness, or pain that doesn’t quite follow the usual rules, the viscerosomatic reflex may be part of the story—and conservative care may help calm the system and restore healthier movement.

If you’ve ever called our office and asked, “Do you have availability for the chair?”—you’re not alone. At this point, the Back-on-Trac Decompression Chair has become something of a local legend. The name may sound intimidating (we promise, no medieval contraptions here), but the experience is quite the opposite. Comfortable, relaxing, and surprisingly gentle, this chair has earned its reputation as one of our most requested therapies. So what’s all the hype about? Let’s take a closer look at why the Back-on-Trac has become a favorite for patients dealing with back and neck pain—and why it might be exactly what your spine has been asking for. Why Spinal Compression Is Such a Big Deal Modern life is not especially spine-friendly. Long hours sitting at desks, staring down at phones, commuting, lifting kids, exercising without enough recovery, and even stress can all add up. Over time, these daily demands compress the spine, especially the discs that sit between each vertebra. These discs are meant to act like shock absorbers, but when they’re under constant pressure, they can lose hydration, bulge, or irritate nearby nerves. That’s when symptoms like stiffness, aching, sharp pain, numbness, or tingling start to show up—and they don’t always go away on their own. This is where decompression therapy comes in. Decompression Therapy: Creating Space to Heal Decompression therapy is a non-surgical, non-invasive approach designed to gently reduce pressure on the spine. Instead of forcing movement or aggressively stretching tissues, decompression works by slowly and carefully creating space between the vertebrae. The Back-on-Trac chair does exactly that. By applying a controlled, gradual stretch, it helps relieve pressure on spinal discs and nerves, encouraging improved circulation and nutrient flow to the area. When pressure is reduced, the body finally gets a chance to do what it does best—heal. A helpful way to think about it: if your spine has been feeling “compressed” by life, decompression therapy gives it room to breathe again. What It’s Like to Use the Back-on-Trac Chair One of the reasons patients love the Back-on-Trac is how comfortable and approachable it feels. You’re seated upright in a supportive chair, secured with straps to ensure proper positioning. Once the session begins, the chair applies a gentle traction force tailored to your body and condition. There’s no sudden pulling, twisting, or cracking. Most people describe the sensation as a deep, relieving stretch—often followed by a feeling of lightness or relaxation. Many patients are surprised by how calming the experience is, especially if they came in expecting something intense. Sessions are typically short, making it easy to fit into your day, and there’s no downtime afterward. You can return to work, errands, or other treatments feeling looser and more comfortable. Who Can Benefit from Back-on-Trac Decompression? Decompression therapy is especially helpful for people whose pain is rooted in disc or nerve compression. Some common conditions we see improvement with include: Herniated or Bulging Discs When discs push outward and irritate nearby nerves, pain can radiate into the arms or legs. Decompression can help reduce that pressure, easing symptoms like sharp pain, tingling, or numbness. Sciatica Pain that travels from the lower back into the hip or leg is often caused by compression of the sciatic nerve. By relieving spinal pressure, decompression therapy may help calm irritated nerves and reduce radiating pain. Degenerative Disc Changes As discs naturally lose hydration with age, the spine can become stiff and painful. Decompression helps offload stressed discs and supports healthier movement patterns. Spinal Stenosis Narrowing of the spinal canal can compress nerves and cause discomfort or weakness. Gentle decompression may help create more space and reduce symptom flare-ups. Chronic Back or Neck Tension Even without a formal diagnosis, everyday aches from posture, overuse, or stress can respond well to decompression therapy. More Than Pain Relief: The Bigger Benefits While pain relief is often the first thing people notice, decompression therapy offers benefits that go beyond symptom management. It’s drug-free. No medications, injections, or reliance on painkillers. It’s non-invasive. No surgery, no recovery period, no risks associated with invasive procedures. It supports long-term spinal health. By improving disc hydration and reducing ongoing compression, decompression therapy can help prevent recurring issues. It pairs well with chiropractic and massage care. Many patients find that decompression enhances the results of adjustments and soft-tissue work by preparing the spine to move more freely. Think of the Back-on-Trac as part of a bigger picture—one tool in a comprehensive approach to caring for your spine. Why an Initial Chiropractic Visit Matters Before hopping into the Back-on-Trac chair, we always start with an appointment with one of our chiropractors. This step is essential. Not every condition is appropriate for decompression, and we want to make sure it’s both safe and effective for you. During your initial visit, your chiropractor will review your health history, assess your spine, and determine whether decompression therapy fits into your personalized care plan. Once you’re cleared, you can schedule Back-on-Trac sessions with confidence, knowing your care is tailored to your body’s needs. We currently offer Back-on-Trac at both of our locations, making it easy to access this popular therapy. Is the Back-on-Trac Right for You? If you’ve been living with back or neck pain, feeling stiff when you wake up, or noticing that everyday activities are becoming less comfortable, decompression therapy may be worth exploring. The Back-on-Trac chair is gentle, effective, and designed to support healing—not just mask symptoms. Sometimes, the most powerful changes come from giving your body the space it needs. Ready to Try “The Chair”? The Back-on-Trac Decompression Chair has helped countless patients find relief, improve mobility, and feel more at ease in their bodies. If you’re curious about whether it’s right for you, we’d love to help. Schedule your initial chiropractic appointment today, and take the first step toward a spine that feels supported, decompressed, and ready for whatever life throws your way.

Thanksgiving is the time of year when we pause to appreciate the big things—family, food, football, and maybe even a perfectly flaky pie crust. But there’s one thing we often forget to be grateful for: our bodies . Every day, your muscles, joints, and connective tissues do a whole lot more than you realize. They carry you through grocery store marathons, marathon-marathons, late-night study sessions, workdays, workouts, and everything in between.  So this season, before you grab that second helping of mashed potatoes (no judgment here), take a moment to thank the parts of you that keep you moving. Here are five simple, meaningful ways to show your body a little gratitude—and feel better in the process.
