“Are you sure you won’t snap my neck?”
“What if you paralyse me?”
Thanks in part to viral YouTube videos and social media, there’s an increase in awareness as well as confusion around chiropractic adjustments. And to be fair, if you’ve never experienced a chiropractic adjustment before, watching someone’s neck move quickly and hearing a loud crack can seem a little intimidating.
The reality, however, is very different from what you see online.
A chiropractic adjustment or manipulation is a highly specific manual technique used to improve the movement of joints that have become stiff, restricted, or uncomfortable. Far from being a forceful twisting of the spine, an adjustment is a precise and controlled procedure delivered only after a thorough assessment of your symptoms, medical history, movement patterns, neurological function, and overall suitability for treatment.
If an adjustment is appropriate, a chiropractor applies a small, carefully directed force to a specific joint. Clinically, this is known as a high-velocity, low-amplitude (HVLA) thrust. While the terminology sounds technical, it simply refers to a very quick movement over a very small distance.
The objective is not to “put bones back into place” or force the body beyond its natural limits. Rather, the goal is to restore normal joint movement, reduce pain, improve function, and help the surrounding muscles relax.
What Causes the Crack?
Of course, chiropractic is perhaps best known for the crack.
The popping sound is not bones grinding together, moving back into place, or breaking. It’s known as a cavitation and occurs when there is a rapid change in pressure within the joint. The joints of the spine are surrounded by a capsule containing synovial fluid, which helps them move smoothly and comfortably. During an adjustment, the pressure within this capsule changes momentarily, producing that familiar snap, crackle, and pop.
Interestingly, while many patients enjoy hearing it, the sound itself is not what creates the therapeutic effect. Some excellent adjustments produce little or no audible release at all.
What Are the Benefits?
The primary benefits of spinal manipulation are improvements in pain, movement, and overall function (Jupin 2025).
Firstly, research suggests chiropractic adjustments can be effective for reducing pain (JAMA 2017). Many patients also report feeling looser and moving more freely immediately following treatment, helping them perform at their very best.
One reason adjustments can feel so effective is that they stimulate specialised receptors within the joints and surrounding tissues. This influences how the nervous system processes movement and pain, often resulting in reduced muscle tension, improved mobility, and an increased range of motion (Langenfeld et al. 2025).
However, an adjustment is only one part of the picture.
At Remedy, we believe the best long-term outcomes come from combining hands-on treatment with expert rehabilitation, movement coaching, education, and lifestyle strategies that support lasting health and performance. The adjustment may provide immediate relief, but it is the wider treatment plan that helps create meaningful and sustainable results.
But Is It Safe?
For the vast majority of people, chiropractic adjustments are considered very safe when performed by a suitably trained and regulated healthcare professional.
At Remedy, safety begins long before treatment itself. Every patient undergoes a detailed consultation and examination designed to identify any potential risk factors, underlying conditions, or reasons why a particular technique may not be appropriate.
If there is any indication that an adjustment is not the right option, we simply won’t perform one.
Instead, treatment may involve a combination of soft tissue therapy, stretching, rehabilitation exercises, mobilisation, traction, medical acupuncture, and tailored lifestyle advice. The treatment is always adapted to the individual rather than forcing every patient into the same approach.
The most common potential reactions following an adjustment are mild and temporary, such as short-lived soreness, stiffness, or fatigue – similar to what you might experience after a new exercise session.
Serious complications are exceptionally rare. Research suggests that severe adverse events following cervical (neck) manipulation occur at a rate estimated between approximately one in several hundred thousand and one in several million treatments.
One concern that is frequently raised is stroke, specifically a condition known as vertebral artery dissection. Current research suggests that patients experiencing the early stages of a dissection often develop neck pain and headache before the condition is diagnosed. As a result, they may seek care from chiropractors, physiotherapists, or medical doctors because of these symptoms. While an association may therefore be observed, current evidence has not demonstrated that chiropractic manipulation causes these events.
This is precisely why thorough screening, clinical expertise, and careful patient selection remain central to safe and effective chiropractic care.
The Bottom Line
A chiropractic adjustment is a precise, controlled technique designed to improve joint movement, reduce pain, and restore optimal function.
When performed by a properly trained chiropractor following a thorough assessment, spinal manipulation is considered a very safe treatment option, with serious complications being exceptionally rare.
And while the crack may be what chiropractic is famous for, at Remedy it is the extras around the adjustment—the improvements in your movement, performance and quality of life—that truly matter.
