Chiropractic Adjustment Techniques Explained (2026)

Steven Lockstone

New patients often assume every chiropractor "cracks backs" the same way, but adjustment techniques vary widely in force, tools and approach. This guide breaks down the six most common chiropractic adjustment techniques used in Australian clinics in 2026 so you know what to expect and what questions to ask before your first visit.

TL;DR

Diversified Technique is the most widely used chiropractic adjustment technique and suits general spinal complaints.
Activator Method uses a handheld instrument instead of manual thrust, a common choice for patients wanting a low-force option.
Flexion-Distraction Technique stretches rather than thrusts the spine, often discussed for disc-related concerns.
Gonstead Technique relies on detailed segment-by-segment analysis before any adjustment is made.
Which technique suits you depends on your presentation, history and comfort, and that call sits with your chiropractor after assessment.

Why this matters

Chiropractic adjustment techniques are not interchangeable. Some rely on a quick manual thrust, others use a spring-loaded instrument, and a few avoid any thrust at all. New patients who understand the differences ask better questions during their first consultation and feel less caught off guard by the sound, sensation or table setup.

If you have not been to a chiropractor before, it helps to read up on how to prepare for your first chiropractor appointment before comparing techniques, since your chiropractor will select an approach based on your history, imaging (where relevant) and physical assessment, not the other way around.

None of the techniques below are described as a cure or guaranteed fix for any condition. Whether a technique is appropriate for you depends on individual assessment by a registered chiropractor.

What makes an adjustment technique suitable for a patient

Force level — some techniques use a fast, low-amplitude thrust; others use gentle, sustained pressure or an instrument.
Joint and tissue tolerance — older patients, those with osteoporosis risk factors, or anyone post-surgery may need lower-force options.
Presenting complaint — disc-related pain, general stiffness and joint-specific issues are approached differently.
Patient preference — some people are comfortable with the cavitation "pop" sound, others prefer techniques without it.
Chiropractor training and clinical judgement — technique selection follows assessment, not patient request alone.
Response to prior care — a technique that felt uncomfortable in the past is usually swapped for an alternative on review.

Chiropractic adjustment techniques at a glance

Technique	Best for	How it works	Key consideration
Diversified Technique	General spinal complaints	Manual, high-velocity low-amplitude thrust	Requires manual dexterity and produces the typical cavitation sound
Activator Method	Patients wanting a low-force option	Spring-loaded handheld instrument delivers a small, controlled impulse	No twisting or thrust motion involved
Thompson Drop-Table Technique	Pelvic and lower back adjustments	Segmented table drops slightly as the adjustment is applied	Table maintenance and calibration affect consistency
Flexion-Distraction Technique	Disc-related concerns	Specialised table gently stretches and flexes the spine, no direct thrust	Sessions can run longer than thrust-based techniques
Gonstead Technique	Detailed, segment-specific analysis	Assessment-heavy approach using posture, palpation and (where indicated) X-ray before a precise single-segment adjustment	More time-intensive per visit
Low-Force Mobilisation	Sensitive joints or a preference against cracking sounds	Slow, sustained pressure without a fast thrust	Change may take longer to notice than with thrust-based methods

1. Diversified Technique: best overall for general spinal complaints

Diversified Technique is the manual adjustment most people picture when they think of chiropractic care: a fast, controlled thrust applied by hand to a specific joint, often producing an audible release of gas from the joint capsule. It is taught as a core technique in most Australian chiropractic programs and used across a wide range of presentations.

Diversified Technique pros:

Broad application across the spine and extremities
Widely taught, so most registered chiropractors are trained in it
Immediate, hands-on feedback for the practitioner during assessment

Diversified Technique cons:

The audible pop can be off-putting for first-time patients
Not always the first choice for patients with reduced bone density or acute inflammation
Requires the chiropractor to physically position and move the patient

Best for: patients without contraindications who are comfortable with manual, hands-on adjusting. Diversified Technique is the default starting point most chiropractors discuss at a first assessment in 2026.

2. Activator Method: best low-force option for cautious or older patients

The Activator Method uses a small, spring-loaded handheld instrument to deliver a quick, controlled impulse to a joint instead of a manual twist or thrust. It is a common alternative for patients who want the sensation of an adjustment without a manual push.

Activator Method pros:

No twisting or manual thrust required
Consistent force delivery from the instrument
Often considered for patients who feel apprehensive about manual techniques

Activator Method cons:

Some patients feel the instrument-based impulse is less noticeable than a manual adjustment
Requires the instrument to be properly calibrated and maintained
Not every presentation responds the same way to a localised impulse

Best for: patients who prefer a gentler introduction to chiropractic adjustment techniques, including those raised in discussions about chiropractic care for seniors with joint stiffness. Whether it's appropriate for you is a question for your chiropractor after assessment.

3. Thompson Drop-Table Technique: best for pelvic and lower back work

The Thompson Drop-Table Technique uses a specially designed table with sections that drop a short distance as the chiropractor applies a light thrust. The slight drop assists the adjustment and reduces the amount of manual force needed from the practitioner.

Thompson Drop-Table pros:

Table assistance reduces the manual force required
Frequently used for pelvic and lower back segments
Generally well tolerated by patients who find manual thrust techniques uncomfortable

Thompson Drop-Table cons:

Requires specific equipment not every clinic has
The mechanical drop can feel unfamiliar on a first visit
Table calibration needs regular checking for consistent results

Best for: patients with lower back or pelvic-related presentations where a chiropractor judges reduced manual force to be appropriate.

4. Flexion-Distraction Technique: best for disc-related concerns

Flexion-Distraction Technique uses a specialised table that gently flexes and stretches the spine in a slow, rhythmic motion, without any high-velocity thrust. It is often discussed in the context of chiropractic techniques for herniated discs, where a gentler, non-thrust approach may be considered following assessment.

Flexion-Distraction pros:

No direct thrust to the spine
Table motion can be adjusted in speed and range
Often discussed alongside disc-related presentations

Flexion-Distraction cons:

Sessions typically run longer than thrust-based adjustments
Requires a dedicated flexion-distraction table
Not every clinic offers this technique

Best for: patients whose chiropractor has identified a disc-related presentation where a stretch-based, non-thrust approach is considered appropriate on assessment.

5. Gonstead Technique: best for detailed, segment-specific analysis

Gonstead Technique places heavy emphasis on assessment before any adjustment: posture analysis, palpation, and where clinically indicated, X-ray review, to identify the precise spinal segment involved. The adjustment itself is a manual, single-segment thrust, delivered without the patient lying in a fully flexed position.

Gonstead Technique pros:

Detailed, structured assessment process before adjusting
Targets a single identified segment rather than a general region
Well documented technique with a long training history

Gonstead Technique cons:

The assessment process takes more time per visit
Specific table and positioning setup required
Not every clinic has a chiropractor trained specifically in this method

Best for: patients who want a highly structured, analysis-first approach and are comfortable with a longer initial assessment.

6. Low-Force Mobilisation: best for sensitive joints or no-crack preference

Low-force mobilisation techniques apply slow, sustained pressure to a joint rather than a fast thrust. There is no cavitation sound, and the movement is gentler in both speed and range compared with thrust-based techniques.

Low-Force Mobilisation pros:

No cracking or popping sound
Gentler entry point for patients new to chiropractic care
Often discussed for sensitive joints or reduced tissue tolerance

Low-Force Mobilisation cons:

Change may take longer to notice compared with thrust-based techniques
Fewer chiropractors specialise heavily in low-force-only practice
Some patients find the lack of an audible release less satisfying, even though the sound has no bearing on outcome

Best for: patients who prefer a gentler technique, want to avoid the cracking sound, or whose chiropractor has flagged reduced tissue tolerance on assessment.

How we ranked these techniques

The order above follows how commonly each technique is taught and used in Australian clinics, how much equipment or specialised training each requires, and the type of presentation each is typically discussed for. It is not a ranking of clinical superiority — a technique lower on this list may be the right one for you depending on your presentation. If you're unsure whether your symptoms need chiropractic input or a GP first, how to know when back pain needs a chiropractor vs a doctor covers the red flags worth knowing before booking either.

Which chiropractic adjustment technique should you choose?

There is no single "correct" technique for every patient. Diversified Technique remains the most broadly applicable starting point discussed at first assessments in 2026, while Activator Method and low-force mobilisation suit patients who want a gentler introduction. Flexion-Distraction and Gonstead techniques are more often discussed for specific presentations like disc-related pain or segment-specific findings.

The honest answer for a new patient in 2026: book an assessment, describe your history and preferences, and let your chiropractor recommend the technique suited to your presentation rather than picking one from a list in advance.

FAQ

What is the most common chiropractic adjustment technique?

Diversified Technique is the most widely taught and used chiropractic adjustment technique in Australia in 2026. It uses a manual, high-velocity low-amplitude thrust and is often the starting point discussed at a first assessment.

Is the Activator Method as effective as manual adjustments?

The Activator Method uses a handheld instrument instead of a manual thrust and is a recognised alternative technique. Whether it’s appropriate compared to manual adjustment for your presentation is a question to raise directly with your chiropractor.

Do all chiropractic adjustments make a popping sound?

No. Techniques like Activator Method, Flexion-Distraction and low-force mobilisation do not involve a fast thrust and typically produce no cavitation sound, unlike Diversified or Thompson Drop-Table techniques.

Which technique is used for disc-related back pain?

Flexion-Distraction Technique is often discussed for disc-related presentations because it stretches the spine gently rather than applying a direct thrust. Suitability is determined on individual assessment.

What is the Gonstead Technique known for?

Gonstead Technique is known for its detailed, segment-by-segment assessment process before a precise single-segment adjustment is applied. It typically requires a longer initial visit than other techniques.

How do I know which chiropractic technique is right for me?

Your chiropractor selects a technique based on your history, presentation and physical assessment, not from a general preference list. Raise any concerns about force level or sensation during your consultation.

Are low-force chiropractic techniques suitable for older patients?

Low-force techniques such as Activator Method or manual mobilisation are commonly discussed for patients with reduced tissue tolerance, including some older adults, but suitability is confirmed on individual assessment.

How many chiropractic adjustment techniques are there?

There are dozens of named chiropractic adjustment techniques taught worldwide, but Diversified, Activator, Thompson Drop-Table, Flexion-Distraction, Gonstead and low-force mobilisation are among the most commonly used in Australian clinics in 2026.

One last thing

The technique itself matters less than most new patients assume — what actually shapes your experience is the assessment before the adjustment. A chiropractor who spends real time on history, posture and movement testing before touching a table is doing the part of the process that determines which of these six techniques, if any, gets discussed with you in 2026.
