When most people think of a chiropractic adjustment, they picture the characteristic popping sound and a firm thrust to the spine. While that describes one approach, it's far from the only one. Chiropractors are trained in a wide range of techniques — some involve high-velocity movements, others use instruments or specialized tables, and some apply no thrust whatsoever. Understanding the main techniques helps you know what to expect, have an informed conversation with your chiropractor, and request an approach that suits your comfort level and condition.
The Main Chiropractic Techniques
The following are the most commonly used and recognized techniques in chiropractic practice. Each has its own clinical applications, training requirements, and appropriate patient population.
Diversified Technique
The most common chiropractic technique, taught at virtually every chiropractic college in the world. The chiropractor applies a precise high-velocity, low-amplitude (HVLA) thrust to a specific spinal joint using their hands. The force is delivered in a specific direction to restore motion to a restricted joint. The familiar "pop" — caused by gas rapidly releasing from the joint capsule (cavitation) — often accompanies Diversified adjustments. It is versatile and can be applied throughout the spine and to extremity joints. Best suited for patients without osteoporosis, acute disc herniation, or other contraindications to thrust techniques.
Gonstead Technique
Considered one of the most precise and thorough chiropractic approaches, the Gonstead Technique involves detailed analysis before any adjustment is made. Gonstead chiropractors use full-spine X-ray analysis to assess spinal biomechanics, along with a nervoscope (an instrument that measures skin temperature differences along the spine to identify areas of nerve irritation) and careful palpation. Adjustments are delivered with a very specific contact point and direction, targeting only the joints identified as dysfunctional. Practitioners often use specialized adjusting chairs and benches for different spinal regions. The technique is known for its diagnostic thoroughness and precision.
Activator Method
The Activator Method uses a small, handheld spring-loaded instrument called an Activator Adjusting Instrument to deliver a quick, low-force impulse to specific spinal segments or joints. Because the device applies a precise, consistent force significantly lower than a manual thrust, it produces no cavitation pop and involves no rotation or extension of the spine. This makes it particularly well-suited for older patients with osteoporosis, patients who are anxious about manual manipulation, those with acute injuries, or anyone who simply prefers a gentler approach. The Activator Method has its own leg-length analysis protocol and is one of the most researched instrument-assisted chiropractic techniques.
Flexion-Distraction (Cox Technique)
Developed by Dr. James Cox, flexion-distraction is performed on a specialized segmented table that gently flexes and distracts the spine in a rhythmic pumping motion. There is no thrusting involved — the technique works by reducing intradiscal pressure, enlarging the spinal canal foramina to relieve nerve compression, and stretching contracted spinal musculature. It is the chiropractic technique with the strongest evidence base specifically for disc herniations and sciatica, making it a first-choice approach for lumbar disc problems. It is also used for spinal stenosis, spondylolisthesis, and post-surgical patients where thrust techniques are contraindicated.
Drop Table Technique (Thompson)
The Thompson Terminal Point technique uses a specialized chiropractic table with segmented drop pieces that are elevated slightly and then release (drop) when the chiropractor applies a thrust. The dropping table section absorbs much of the force of the adjustment, allowing the chiropractor to use less physical effort while still delivering a specific thrust. The drop mechanism also creates a unique movement pattern through the joint being adjusted. This technique is particularly useful for adjusting the pelvis, sacroiliac joints, and lumbar spine, and is often more comfortable for patients than full manual manipulation at those levels.
SOT — Sacro-Occipital Technique
SOT (Sacro-Occipital Technique) is a low-force approach that focuses on the relationship between the sacrum (base of the spine) and the occiput (base of the skull), and how tension in the dural system and craniosacral mechanism affects the entire body. Treatment often involves placing triangular wedge-shaped blocks under the pelvis and allowing gravity and body weight to gently reposition the sacrum over several minutes. SOT categories guide which positions and additional techniques are used. It is particularly gentle and well-suited for patients who cannot tolerate manual thrust techniques, those with chronic conditions, and children or elderly patients.
Myofascial Release and ART
Myofascial release and Active Release Technique (ART) are not chiropractic adjustments — they are soft tissue therapies commonly used alongside spinal manipulation. Myofascial release uses sustained pressure and stretching to release restrictions in the fascia (the connective tissue surrounding muscles). ART is a patented, provider-certified technique in which the practitioner applies specific tension to a muscle while the patient moves through a defined range of motion, breaking adhesions and restoring normal tissue movement. Both are widely used for repetitive strain injuries, plantar fasciitis, carpal tunnel syndrome, and post-injury scar tissue.
IASTM — Instrument-Assisted Soft Tissue Mobilization
IASTM involves using specially designed stainless steel or titanium tools with beveled edges to detect and treat areas of restricted fascial movement, scar tissue, and chronic tendinopathy. The instruments allow the clinician to apply controlled microtrauma to affected soft tissue, stimulating a local inflammatory healing response that promotes tissue remodeling. Common branded versions include Graston Technique and HawkGrips. IASTM is particularly effective for conditions like Achilles tendinopathy, IT band syndrome, lateral epicondylosis (tennis elbow), and post-surgical adhesions. Many chiropractors incorporate it into broader treatment plans alongside spinal adjustments.
Which Technique Is Right for You?
The right technique depends on your condition, your age and bone health, your personal preference, and your chiropractor's training. Here are some general principles:
- For acute disc herniations or sciatica, flexion-distraction is typically preferred over high-velocity thrust techniques.
- For older adults or those with osteoporosis, low-force options like the Activator Method, SOT, or flexion-distraction are generally safer and more comfortable.
- For general mechanical back or neck pain in otherwise healthy adults, Diversified or Gonstead are proven and effective.
- For soft tissue problems — muscle tightness, tendinopathy, fascial restrictions — ART, IASTM, or myofascial release may be the primary focus of treatment.
- For sacroiliac and pelvic issues, Drop Table technique is frequently preferred.
Importantly, most experienced chiropractors do not use a single technique exclusively. They adapt their approach based on each patient's clinical presentation, often combining elements of multiple techniques in the same visit. A chiropractor trained in Diversified may also use Activator for certain segments, flexion-distraction for disc-related pain, and ART for accompanying muscle problems — all in one session.
You can always ask about technique — and request a gentler approach. Before your first adjustment, ask your chiropractor what technique they plan to use and why it's appropriate for your condition. If you are uncomfortable with the idea of a manual thrust, say so. Every reputable chiropractor has low-force alternatives available and will accommodate your preference. Patient comfort and consent are central to ethical chiropractic practice, and there is no single "correct" technique that works for every patient.
Asking Your Chiropractor the Right Questions
When you visit a chiropractor for the first time, the following questions help you understand the planned approach and make an informed decision:
- "What technique do you primarily use, and have you had post-graduate training in it?"
- "Is this technique appropriate for my specific condition, and are there alternatives if I prefer something gentler?"
- "Will you be taking X-rays, and how will those inform your treatment approach?"
- "Do you use soft tissue therapy alongside adjustments, or is it purely spinal manipulation?"
- "What should I expect to feel during and after the adjustment?"
A chiropractor who welcomes these questions, explains their reasoning clearly, and adjusts their approach based on your responses is practicing patient-centered care — which is what you should expect from any licensed healthcare provider.
