There are dozens of named chiropractic techniques, but most adjustments fall into a few families: a quick, precise thrust (the classic “crack”), a gentle instrument-assisted impulse, a slow stretching or table-assisted movement, and non-thrust mobilisation. Which one you get should depend on your diagnosis, your age, your comfort and how your body responds, not on a clinic’s favourite habit. This guide explains each type in plain English, what to expect, and what a good chiropractor should ask before touching your spine.
TL;DR
- Most adjustments are either a high-velocity, low-amplitude (HVLA) thrust or a gentler alternative: instrument-assisted, table-assisted or mobilisation without a thrust.
- The “pop” is gas moving in a joint. It is not the goal, and a good adjustment does not need one.
- Diversified is the most widely used technique, but the right one for you depends on your condition, your preferences and your examination findings.
- Check that your chiropractor is on the General Chiropractic Council (GCC) register, and expect a proper history and examination before any adjustment.
- Regular “maintenance” visits are for people who have already recovered well. They are not a requirement for everyone.

What a chiropractic adjustment actually is
An adjustment, or spinal manipulation, is a hands-on (or instrument-assisted) movement applied to a joint, usually in the spine, to improve how it moves and to ease pain. The NHS describes chiropractic treatment as including spinal manipulation, short sharp thrusting movements, gradually moving joints into different positions, and stretching muscles in different directions. So the NHS itself treats “adjustment” as a range of movements, not a single move.
The literature draws a useful line between two ideas. A spinal adjustment typically uses a high-velocity, low-amplitude thrust to restore motion, while mobilisation uses gentle, passive movements without a thrust. Everything below sits on one side of that line or the other, or blends the two.
The main types of chiropractic adjustment
Diversified technique
This is the technique most people picture: you lie on a treatment table, the chiropractor positions a joint and delivers a fast, shallow thrust. It is an HVLA technique. A job analysis of chiropractic found it was used by around 96% of chiropractors surveyed, though the list is dated and reflects North American practice, so treat the figure as a sign of how common it is rather than a UK statistic.
Diversified is popular because it is adaptable. The same basic skill can be applied to the lower back, mid-back, neck and even joints outside the spine, and the force, speed and position can be modified. People searching for “diversified adjustment” are usually asking whether it is safe or painful. For most people it is neither: a brief pressure, sometimes a pop, and then a looser feeling. If you are tense, sore or simply do not want a thrust, say so. A good clinician will change approach.
Activator method
The Activator uses a small handheld spring-loaded instrument that delivers a light, quick tap to a specific spot. There is no twisting and no big movement. The same job analysis reported it as the second most widely used technique, at around 63% of chiropractors.
It suits people who are nervous about manual thrusts, who are frail or in a lot of pain, or whose joints are sensitive. Some clinicians also use it on shoulders, hips and the jaw. The trade-off is less of a sense of immediate “release”, which some patients expect but others are glad to avoid.
Flexion-distraction
Here the table itself moves. You lie face down while the table gently flexes and stretches your lower spine, and the chiropractor applies light pressure with their hands. It is slow, rhythmic and rarely produces a pop.
This approach is often chosen for lower back and leg symptoms where a thrust feels too much, including some disc-related pain. It is a good example of how the “best” technique depends on the problem, not on a ranking.
Drop table technique
A drop table has sections that are raised slightly and then drop a few millimetres when the chiropractor applies a quick, light thrust. The small drop is meant to let the thrust work with less force. It is a variation of the thrust family, so the sensation is similar to a gentle diversified adjustment but often feels lighter. It can suit people who find firm manual thrusts uncomfortable. Note that tables and settings vary between clinics, so ask what equipment will be used and why.
Gonstead and other segment-specific methods
Gonstead is a thrust technique built around very detailed analysis of one spinal segment: palpation, posture, heat and sometimes imaging, then a specific, targeted adjustment. Other named systems (there are well over a hundred in total) differ in how they decide where to adjust and how to deliver the force. Names matter less than reasoning. A clinician who can explain why this joint, why this method and what they expect to change is worth more than any brand.
Mobilisation and soft tissue work
Not every session involves a thrust. Joint mobilisation moves a joint through its range slowly and passively. Soft tissue therapy, trigger point work and myofascial release address tight muscles around the joint. Many chiropractors combine these with exercises and advice. For people with acute, irritable pain, or those who prefer a lighter touch, this can be the sensible starting point, with thrust techniques added later if appropriate.
Techniques at a glance
| Type | How it feels | Typical use | Pop likely? |
|---|---|---|---|
| Diversified (HVLA thrust) | Quick, firm, brief | Back, neck and other joints | Often |
| Activator (instrument) | Light tap | Sensitive patients, extremity joints | Rarely |
| Flexion-distraction | Slow, rhythmic stretch | Lower back and leg symptoms | Rarely |
| Drop table | Light thrust with a small drop | Patients preferring less force | Sometimes |
| Gonstead (targeted thrust) | Specific, firm | Single-segment problems | Often |
| Mobilisation / soft tissue | Slow, passive, massage-like | Acute pain, stiffness, muscle tension | No |
About the pop
Many patients worry about the sound, or chase it. It is a cavitation, a release of gas within the joint fluid, and it is not the aim of treatment. An adjustment can be effective without any sound, and a loud pop does not mean it worked better. If someone tells you that you must hear a crack for treatment to count, be wary.
How a chiropractor chooses the right technique
The technique should follow the assessment, never the other way round. A sound first appointment includes:
- A detailed history. When it started, what eases or aggravates it, previous injuries, medication, general health.
- A physical and neurological examination. Movement, joint tests, reflexes, strength and sensation, especially if you have arm or leg symptoms.
- Screening for red flags. Signs of something that is not a chiropractic problem at all.
- A clear explanation and plan. What they think is going on, what the options are, how many visits to expect before review, and how progress will be measured.
The research on choosing a clinician points the same way: look for a comprehensive assessment with history, physical and neurological testing, clear clinical reasoning, willingness to work with your GP or other specialists, and an individual plan. Routine x-rays are not usually needed when the history and examination are clear enough, according to NHS referral guidance for neck problems.
Red flags: when an adjustment is the wrong answer
Certain symptoms mean you need medical assessment first, not manipulation. The same NHS guidance lists rapidly progressing neurological loss such as bladder or bowel problems, unexplained weight loss, fever, severe unrelenting night pain, and vascular signs such as transient blindness. An international framework of red flags for serious spinal pathology explains that clinicians weigh combinations of findings, because no single sign is diagnostic alone.
If you develop new numbness around the groin or saddle area, trouble controlling your bladder or bowels, or sudden weakness in a leg, do not wait for an appointment: go to A&E or call 999. Our page on lumbar radiculopathy symptoms and when to seek emergency care goes through what to look out for.
Risks, stated plainly
The NHS says chiropractic is generally safe when carried out by a trained, registered chiropractor. Mild aches, stiffness or tiredness are common and usually pass within a few days. It also notes a risk of more serious problems, such as stroke, from spinal manipulation, which is rare. This is one reason neck technique and screening matter so much, and why a clinician should explain the risks and get your consent before treating your neck. Newer or unusual manoeuvres deserve extra caution: a clinical commentary on the Y-axis manipulation examined the efficacy and safety of one such technique, and a paediatric scoping review raised concerns about high-velocity, high-amplitude manoeuvres lacking established safety protocols.
Adjustments for different people
Neck pain and headaches. Neck work is usually the most carefully screened and often the gentlest. Many patients start with mobilisation, soft tissue work or instrument-assisted methods. You can read how we approach this on our pages for neck and shoulder pain and headaches and migraines.
Low back pain and sciatica. Thrust, table-assisted and flexion-based methods are all used, depending on whether the pain is mainly in the back or travels into the leg. See our pages on low back pain and sciatica and leg pain.
Pregnancy and children. Technique choice changes substantially: lighter, non-thrust approaches are the norm, and the evidence base for children is still developing. Our guide to chiropractic during pregnancy in the UK sets out safety checks worth making.
Older adults or those with osteoporosis. Bone health matters. Tell your chiropractor about diagnoses and medication, so that force and technique can be adjusted.
Wellness and maintenance care
Some people continue visits after their pain settles. This is often called wellness or maintenance care. A systematic review of maintenance care describes it as continuing treatment after optimum benefit has been reached, and it is aimed at people who responded well and want to reduce the chance of recurrence, not at everyone who has ever had treatment.
There is no standard number of adjustments. Frequency depends on age, lifestyle, physical demands and your history of flare-ups. Some people compare it to dental check-ups, and a monthly rhythm is sometimes mentioned, but it should be agreed with you, reviewed against your progress, and stopped if it is not helping. Be cautious of any clinic that sells a long block of prepaid visits before it has assessed you.
What you do between visits counts too. Sleep position and your mattress can aggravate a stiff back, and this overview of adjustable beds and back pain is a reasonable starting point if you are rethinking your set-up. Exercise, walking and staying active matter more than any single technique.
Perspective: why we start with the assessment, not the technique
We have been treating patients for over 25 years, and the question “which adjustment is best?” almost always puts the cart before the horse. At Elaris, we look at structural, neurological and emotional factors together, because pain that keeps coming back rarely has one cause. A stiff joint may be the symptom; the reason it is stiff may be elsewhere.
So we begin with a hands-on examination and neurological testing, explain what we find in plain language, and give you a written treatment plan. Progress is measured at every stage, and you see the same two practitioners each visit, so nobody is guessing from scratch. If a gentler approach suits you better than a thrust, we say yes. The goal is not a click. It is getting you moving, understanding why you hurt and needing us less over time.

Choosing a chiropractor in Essex
Start with registration. Chiropractor is a protected title in the UK, and the GOV.UK regulated professions register confirms the General Chiropractic Council regulates the profession under the Chiropractors Act 1994. You can check the GCC register online before you book. Then ask:
- Will I have a full examination before any treatment?
- Will you explain the diagnosis, the options and the risks?
- Can I decline a thrust and still be treated?
- How will we measure whether this is working, and when will we review?
- Who will treat me each time?
If you are local, we see patients from Maldon, Tiptree, Witham and surrounding villages, and you can find our pages for Maldon, Tiptree and Witham.
Book a first consultation
Our first consultation and examination costs £105. It covers a thorough history, a hands-on and neurological examination and an explanation of what we think is happening and what we recommend. You can arrange it through our Great Totham clinic page. If chiropractic is not right for your symptoms, we will tell you and point you to the appropriate care.
FAQ
Which type of chiropractic adjustment is best?
There is no single best type. Thrust techniques such as diversified are the most commonly used, while instrument-assisted, table-assisted and mobilisation methods suit people who want less force. The right choice follows your examination, your condition and your preferences.
Does a chiropractic adjustment hurt?
Most people feel brief pressure or a stretch, and some feel mild soreness or tiredness afterwards. The NHS says such side effects are usually mild and pass in a few days. Tell your chiropractor if anything hurts during treatment so they can change approach.
Do I have to hear the pop for it to work?
No. The sound is gas released within the joint fluid and is not the aim. Gentler techniques often produce no sound at all and can still be effective.
Is it normal to have regular adjustments forever?
No. Maintenance care is meant for people who have recovered well and want to reduce recurrence, and the frequency should be individual, reviewed and agreed with you. There is no standard number of visits that suits everyone.
What are the warning signs that I should see a doctor instead?
Rapidly worsening weakness, bladder or bowel changes, numbness in the saddle area, fever with back pain, unexplained weight loss or severe night pain all need urgent medical assessment. Go to A&E or call 999 for sudden loss of bladder control or leg weakness.
