If you’ve ever been to a chiropractor, you may have experienced the distinctive “click” or “pop” sound during an adjustment. But what exactly causes this noise? And more importantly, what happens inside your body when a chiropractor performs an adjustment?

Understanding the mechanics and benefits of a chiropractic adjustment can help ease any anxiety and show why it’s a trusted treatment for back pain, neck pain, and overall wellness.

In this article, we’ll take you behind the scenes of a chiropractic adjustment to explain what happens during the process and why it feels so good afterward.

What Is a Chiropractic Adjustment?

A chiropractic adjustment—also called spinal manipulation—is a precise, controlled movement applied to a joint of the spine or other parts of the body. The goal is to restore proper alignment, improve joint function, and reduce pain.

Chiropractors are specially trained healthcare professionals who assess your spine’s mobility and identify areas where joints may be restricted or misaligned, known as subluxations.

The Science Behind the "Click and Pop" Sound

The familiar “click” or “pop” heard during an adjustment is caused by cavitation. This occurs when:

• The chiropractor applies a quick, gentle force to a joint.
• This force causes a rapid change in joint pressure.
• Gases (mostly nitrogen) dissolved in the joint fluid form tiny bubbles.
• When these bubbles collapse or burst, they create the popping sound.

This process is similar to the sound you hear when cracking your knuckles—but a professional adjustment targets specific joints and is much safer and more controlled.

What Happens to Your Body During an Adjustment?

1. Joint Realignment

The adjustment restores proper positioning of the vertebrae or other joints, helping to reduce abnormal stress on muscles, ligaments, and nerves.

2. Improved Range of Motion

Releasing joint restrictions helps increase mobility, making it easier to move without stiffness or pain.

3. Nervous System Benefits

Proper spinal alignment can improve communication between your brain and body by reducing nerve irritation. This may enhance overall function and healing.

4. Pain Relief

Adjustments often decrease inflammation and muscle tension, leading to reduced pain and improved comfort.

5. Muscle Relaxation

Many patients experience a sense of relaxation as muscles around the adjusted joint loosen and tension dissipates.

What to Expect During Your Chiropractic Appointment

• Initial Assessment: Your chiropractor will review your health history, symptoms, and conduct a physical exam.
• Palpation and Motion Testing: The chiropractor feels and moves your spine to find restricted joints.
• Adjustment: The chiropractor uses hands or a specialized instrument to deliver the adjustment.
• Post-Adjustment Advice: You may receive recommendations on stretches, exercises, or lifestyle changes.

Is it Safe to Crack Your Own Back?

While occasional self-manipulation can provide temporary relief, it’s not a substitute for professional chiropractic care. Chiropractors are trained to identify the underlying causes of joint dysfunction and apply safe, targeted techniques.
Repeated or improper self-cracking can lead to injury or worsen problems.

Who Can Benefit from Chiropractic Adjustments?

Chiropractic care is beneficial for a range of conditions, including:

• Lower back pain
• Neck pain and headaches
• Sciatica and nerve-related pain
• Joint stiffness or restricted movement
• Sports injuries
• Postural imbalances

Conclusion

Behind the familiar “click and pop” of a chiropractic adjustment lies a complex and carefully controlled process designed to restore joint function, reduce pain, and promote overall health. Whether you’re new to chiropractic care or considering treatment for chronic discomfort, understanding what happens during an adjustment can help you feel confident in your journey to wellness.
