A chiropractic adjustment is a controlled manual technique used to improve movement in a joint that feels stiff or restricted. Although the movement happens quickly, a professional adjustment should never be sudden from the patient’s perspective.
Before an adjustment takes place, the chiropractor should explain the procedure, assess the area, discuss potential benefits and risks, and obtain your consent. You should know which part of your body will be treated and what you are likely to feel.
The familiar popping sound may occur, but it is not the purpose of the treatment. Your bones are not being snapped back into place, and an adjustment can still improve movement without producing any sound.
Most importantly, you remain in control throughout the appointment. If you are nervous or do not want a manual adjustment, gentler alternatives can often be used.
What Is a Chiropractic Adjustment?
A chiropractic adjustment involves applying a quick, controlled movement to a specific joint. Chiropractors commonly use adjustments on the spine, but similar techniques may be used on joints such as the shoulders, hips, knees, ankles and wrists.
The clinical goal is usually to:
- Improve movement in a restricted joint
- Reduce stiffness
- Influence the nervous system’s processing of pain
- Reduce surrounding muscle guarding
- Make normal movement feel easier
- Create an opportunity for active rehabilitation
An adjustment is not a cure for every painful condition. It is one treatment option within a broader plan that may also include soft-tissue therapy, mobilisation, dry needling, exercise and practical lifestyle changes.
What Happens Before an Adjustment?
A chiropractor should not adjust you without first understanding your symptoms and confirming that the technique is appropriate.
During an initial consultation, the chiropractor may review:
- The location and nature of your pain
- How and when the symptoms began
- Previous injuries or operations
- Medical conditions and medication
- Numbness, tingling or muscle weakness
- Recent accidents, falls or trauma
- Activities that improve or aggravate the problem
- Your work, exercise and sleeping habits
The physical assessment may include range-of-motion testing, palpation, orthopaedic tests and a neurological examination.
This process helps identify the likely cause of your symptoms and screens for conditions that should not be treated with an adjustment.

Step 1: Reviewing How You Feel
Each appointment should begin with a brief review. Your chiropractor will ask how you responded to the previous treatment and whether your symptoms have changed.
You should mention any new pain, numbness, dizziness, headaches, weakness or changes in your general health. This information may affect whether an adjustment is performed or which technique is selected.
The chiropractor may also recheck a relevant movement. For example, if you previously struggled to turn your neck to the right, that movement can be measured before and after treatment.
Step 2: Explaining the Procedure
Before the adjustment, the chiropractor should explain:
- Which joint will be treated
- Why the joint has been selected
- How you will be positioned
- Which technique will be used
- What the movement may feel like
- Whether a popping sound may occur
- The expected benefits
- Possible side effects and relevant risks
- Which alternative techniques are available
You should have time to ask questions. The explanation should use clear language rather than technical terms intended to pressure or frighten you.
Step 3: Providing Informed Consent
Consent is an essential part of chiropractic treatment. It is not merely a form signed at reception.
You should understand the proposed treatment and agree to it before the chiropractor proceeds. You can consent to one technique while declining another.
For example, you may be comfortable with treatment to your upper back but not want your neck adjusted. You may prefer gentle mobilisation instead of a high-velocity technique.
You can also withdraw your consent at any point. If you ask the chiropractor to stop, the movement should stop immediately.
Step 4: Selecting the Joint
The chiropractor will use the findings from your history and physical examination to select the joint that requires treatment.
A hands-on assessment may identify:
- Restricted joint movement
- Muscle guarding
- Local tenderness
- Differences between the left and right sides
- A movement that reproduces your familiar symptoms
Feeling one tender spot does not automatically prove that it needs to be adjusted. The chiropractor should consider the full clinical picture rather than adjusting every area that feels tight.
Step 5: Positioning the Patient
Your position depends on the joint and technique being used.
For a lower back adjustment, you may lie on your side with your hips and knees slightly bent. For an upper-back or neck technique, you may lie face down or face up on a padded chiropractic table.
The chiropractor should guide you into position gradually and explain each step. The aim is to isolate the target joint while keeping the rest of your body as relaxed and comfortable as possible.
Tell the chiropractor if a position causes pain, makes you feel vulnerable or creates anxiety. The setup can usually be modified, or another technique can be selected.
Step 6: Choosing the Technique
Not every adjustment involves twisting or a loud crack. Chiropractors can choose from several techniques according to the patient’s diagnosis, age, bone health and preferences.
Manual Adjustments
A manual high-velocity, low-amplitude adjustment involves a quick movement over a short distance. The chiropractor uses their hands to apply a controlled impulse to the target joint.
This technique is commonly used for adults with mechanical joint restrictions when no contraindications are present.
The patient may feel brief pressure or a fast stretch. A popping sound may occur, but it is not required.
Drop-Table Adjustments
A drop table contains sections that lift slightly and move down a short distance when pressure is applied.
The moving section of the table assists the technique, allowing the chiropractor to use a controlled force without placing the patient into a large twisting movement.
The patient usually feels a light thud or vibration from the table. This approach can be helpful for people who dislike traditional positioning or feel anxious about a manual adjustment.
Instrument-Assisted Adjustments
An adjusting instrument delivers a small, rapid impulse to a specific area. The patient usually feels a light tap or click rather than a stretch or twist.
This technique may be considered for:
- Nervous first-time patients
- Older adults
- Selected patients who require low-force care
- People who dislike popping sounds
- Patients who cannot comfortably assume a manual-adjustment position
The instrument should still be used according to a diagnosis and clinical examination. Low force does not remove the need for careful screening.
Gentle Joint Mobilisation
Mobilisation uses slower, rhythmic movements within a joint’s normal range. It does not involve a quick thrust.
It may be appropriate for patients with severe acute pain, significant muscle guarding, sensitive joints or anxiety about manual treatment.
Mobilisation often feels like a gradual stretch and normally does not produce a popping sound.
Step 7: Performing the Adjustment
Once you are comfortable and the target joint has been isolated, the chiropractor applies the selected technique.
During a manual adjustment, the chiropractor gently takes up the available movement in the joint before delivering a quick, shallow and controlled thrust. The movement remains within the joint’s anatomical limits.
The adjustment itself usually lasts less than a second.
You may experience:
- A brief stretch
- A sense of pressure
- A popping sound
- An immediate feeling of release
- No dramatic sensation at all
The speed can surprise a first-time patient, but an adjustment should not feel uncontrolled. If the setup causes pain or you cannot relax, the chiropractor should stop and modify the technique.
What Causes the Popping Sound?
The popping or cracking sound is not caused by bones grinding together.
Many joints are surrounded by a capsule containing synovial fluid. This fluid lubricates the joint and allows the surfaces to move smoothly.
When the joint surfaces separate rapidly during an adjustment, the pressure inside the capsule changes. Dissolved gases in the joint fluid form a cavity or bubble. This process, known as cavitation or tribonucleation, produces the popping sound.
The sound is similar in principle to the pressure change that occurs when a sealed container is opened. It does not mean that a bone has cracked or that something was forced back into place.
Are Bones Being Put Back Into Place?
No. A chiropractic adjustment does not snap misplaced bones back into position.
If a spinal joint were genuinely dislocated, it would be a medical emergency requiring urgent medical care.
A more accurate explanation is that a joint can become stiff or restricted in part of its normal movement. This may occur because of pain, inflammation, muscle guarding, injury or prolonged positioning.
The adjustment introduces movement into that restricted joint. It may help the joint move more comfortably, but it does not permanently realign the skeleton.
This is why exercise and daily movement remain important. Hands-on care can improve mobility, while rehabilitation helps the patient build the strength and control needed to use that movement.
Why Can an Adjustment Reduce Pain?
The effects of an adjustment involve both the joint and the nervous system.
Joints contain sensory receptors that continuously send information about movement and position to the spinal cord and brain. A rapid joint movement produces a strong burst of sensory information.
This input may temporarily change how the nervous system processes pain and muscle tension. Some patients experience an immediate reduction in stiffness or find that a previously painful movement becomes easier.
Improved joint movement may also reduce protective muscle guarding around the area.
The response is not identical for every patient. Some feel an immediate change, while others improve gradually over several appointments combined with exercise and activity changes.
Can an Adjustment Work Without a Crack?
Yes. An adjustment or mobilisation can improve movement without producing any popping sound.
The sound is not a measure of clinical success. It does not prove that the correct joint was treated or that the patient’s condition has been resolved.
Instrument-assisted techniques, drop-table methods and gentle mobilisation may produce little or no sound while still affecting joint movement and sensory input.
The result should be judged by measurable changes such as:
- Improved range of motion
- Reduced pain during movement
- Less muscle guarding
- Improved daily function
- Better tolerance for sitting, walking or exercise
Step 8: Checking the Response
After the adjustment, the chiropractor should check how you feel before moving on.
The treated joint may be reassessed, and the movement tested before treatment can be repeated. If your neck rotation was limited, for example, the chiropractor may measure it again.
This post-treatment check helps determine whether:
- Movement has improved
- Pain has changed
- Muscle guarding has decreased
- The technique had a positive, neutral or negative effect
- Further treatment is appropriate
The chiropractor should not repeatedly adjust the same area simply because no popping sound occurred.
Step 9: Getting Up From the Table
After treatment, you may be advised to sit up slowly. This is particularly important if you have been lying down for a while, are prone to dizziness or have low blood pressure.
Some patients feel immediately lighter or more mobile. Others notice only a subtle change.
An immediate dramatic result is not required for an adjustment to be useful. The important question is whether movement and function improve over time.
What Should You Do After an Adjustment?
Most patients can continue with their normal day after an uncomplicated adjustment. Your chiropractor may provide specific advice based on your condition.
General recommendations may include:
- Take a short, gentle walk
- Keep moving within a comfortable range
- Avoid immediately returning to heavy lifting if the area is irritated
- Complete only the exercises prescribed for you
- Use ice or heat if recommended and if it feels helpful
- Pay attention to how your symptoms respond
Drinking water is sensible for general health, but it does not lock an adjustment into place or flush toxins released by treatment.
The best aftercare is normally gentle movement and following the rehabilitation plan designed for your condition.
Is It Normal to Feel Sore After an Adjustment?
Mild soreness, tenderness or stiffness can occur after an adjustment. It may feel similar to the discomfort experienced after unfamiliar exercise.
Some patients also report temporary fatigue or a mild headache. These reactions will often begin settling within 24 to 48 hours.
Not every patient feels sore. Some experience immediate relief, while others notice gradual improvement over the following day or two.
If you have a history of reacting strongly to manual treatment, tell your chiropractor before the adjustment. A gentler technique or lower treatment dose may be more appropriate.
When Should You Contact Your Chiropractor?
Contact the practice if:
- Soreness lasts longer than 48 hours without improving
- The discomfort is considerably worse than expected
- Your original symptoms become more intense
- You develop new radiating pain
- You experience new numbness or tingling
- You are concerned about any reaction
The chiropractor should review the response before repeating the same technique. Treatment may need to be modified, postponed or stopped.
Which Symptoms Require Immediate Medical Attention?
Serious complications are uncommon, but certain symptoms should never be dismissed as a normal adjustment reaction.
Seek emergency medical care if you experience:
- A sudden severe or unusual headache
- Slurred speech
- Facial drooping
- New double vision or loss of vision
- Severe dizziness with difficulty walking
- New weakness or numbness on one side of the body
- Confusion or loss of consciousness
- Sudden loss of bowel or bladder control
- New difficulty passing urine
- Numbness around the groin, buttocks or inner thighs
- Rapidly worsening arm or leg weakness
- Sudden foot drop
Do not wait for a routine follow-up appointment if these symptoms appear. Contact emergency services or go to the nearest emergency department.
When Should a Chiropractor Not Perform an Adjustment?
Knowing when not to adjust is an essential part of safe chiropractic practice.
A high-velocity adjustment may be unsuitable when a patient has:
- An acute fracture or dislocation
- Severe osteoporosis
- Structural instability
- Active bone or spinal infection
- Cancer affecting the treatment area
- Progressive spinal cord or nerve compression
- A serious bleeding disorder
- Certain significant vascular conditions
- Severe pain following recent trauma that has not been investigated
- New neurological symptoms requiring medical assessment
Some conditions require a complete referral, while others may still allow carefully modified treatment after appropriate medical clearance.
An ethical chiropractor should never use an adjustment when the potential risk outweighs the likely benefit.
How Are Adjustments Modified for Nervous Patients?
Anxiety about chiropractic adjustments is common, especially when someone has watched dramatic treatment videos online.
A nervous patient should be given additional time to ask questions and understand the options. The chiropractor can demonstrate the setup before applying any pressure.
A simple stop signal can also help the patient feel in control. If the patient raises a hand or says “stop,” all movement should stop immediately.
Gentler options may include:
- Instrument-assisted adjustments
- Drop-table techniques
- Slow joint mobilisation
- Soft-tissue therapy
- Stretching and rehabilitation exercises
Trust should be built gradually. A patient should never be surprised with an adjustment they did not expect or approve.
How Are Babies and Children Treated?
Babies and children are not treated in the same way as adults. Forceful adult-style manipulation should not be used on an infant.
Where paediatric chiropractic care is clinically appropriate, the approach should use extremely gentle pressure suited to the child’s age, development and body size.
The chiropractor must also recognise when a child requires assessment by a paediatrician or another healthcare professional. Chiropractic treatment should not be promoted as a cure for infections, colic, asthma or internal medical conditions.
How Are Adjustments Modified During Pregnancy?
A pregnant patient’s comfort and safety should guide every part of the appointment.
Pregnancy pillows or appropriately designed tables can support the abdomen and allow the patient to lie comfortably. Side-lying and seated techniques may also be used.
Because pregnancy changes the body’s weight distribution and ligament behaviour, adjustments should be specific and carefully controlled. The chiropractor should avoid unnecessary force or positions that place pressure on the abdomen.
Chiropractic care may help manage mechanical back or pelvic discomfort, but it should not replace obstetric care or be presented as a guaranteed way to change a baby’s position.
How Are Older Adults Adjusted?
Older adults may have osteoarthritis, reduced mobility, fragile skin, joint replacements or lower bone density. The technique must be adapted accordingly.
A chiropractor may use drop-table methods, instrument-assisted treatment or gentle mobilisation rather than forceful twisting.
The aim may be to maintain useful movement and reduce stiffness rather than restore the joint to how it functioned decades earlier.
Can Someone With Osteoporosis Be Adjusted?
Severe osteoporosis increases the risk of fracture and is a major reason to avoid standard high-velocity manipulation at the affected area.
Depending on the patient’s medical history and bone density, the chiropractor may use very gentle soft-tissue techniques, low-force mobilisation or exercise guidance instead.
A sudden onset of back pain following a minor movement, cough or fall may indicate a compression fracture. Treatment should be postponed until the patient has received appropriate medical assessment and imaging.
How Is Severe Acute Pain Treated?
Patients experiencing severe acute pain may be unable to lie comfortably or relax into a standard adjustment position.
Forcing a painful joint through a manual technique can increase muscle guarding and make the patient feel worse.
Gentler options may include:
- Low-force mobilisation
- Flexion-distraction techniques
- Instrument-assisted treatment
- Comfortable positioning
- Soft-tissue therapy away from highly irritated structures
- Basic pain-free movement exercises
The aim is to calm the condition and gradually restore movement. A forceful adjustment is not automatically the fastest or most appropriate solution.
A Nervous Patient’s First Adjustment
A 34-year-old corporate accountant, whom we will call Sarah, visited the practice with chronic neck tension and recurring tension headaches. Long working hours at a desk regularly aggravated her symptoms.
Sarah was extremely anxious about being adjusted. She had watched online videos showing loud and aggressive neck manipulations and associated the popping sound with bones breaking.
She was also worried about losing control while someone twisted her neck. Information she had read about rare vascular complications increased her fear.
How We Built Trust
Before treatment began, we spent time discussing each concern. Her anxiety was treated as reasonable rather than dismissed.
I used a spine model to explain the difference between a restricted joint and a true dislocation. I also explained that the popping sound is associated with a pressure change inside the joint rather than bones grinding together.
We discussed the potential benefits, limitations and risks of treatment. No screening procedure can guarantee that every risk has been eliminated, but a detailed history and physical examination help determine whether manual treatment is appropriate.
Sarah was offered a non-twisting, low-force option. We agreed that she could ask me to stop at any point. Once she understood the plan and felt comfortable, she provided consent.
The Technique We Selected
Instead of a manual neck adjustment, I selected an instrument-assisted technique.
Sarah lay face down with her head and neck in a comfortable neutral position. The examination identified restricted movement around the right side of the upper neck.
The rubber-tipped adjusting instrument was placed over the selected area. After explaining what she would feel, I delivered a small, rapid impulse.
Sarah described the sensation as a light tap. Her neck was not twisted, and no popping sound occurred.
The Measurable Result
Before treatment, Sarah could rotate her neck approximately 45 degrees to the right, and the movement produced a painful pulling sensation.
After the low-force treatment, rotation improved to approximately 70 degrees without sharp discomfort. The protective tension in the surrounding neck and shoulder muscles also decreased.
By her third appointment, Sarah reported that the frequency and intensity of her tension headaches had decreased by approximately 75%.
As her confidence grew, she progressed to gentle manual mobilisation. She remained in control of the techniques used throughout her care.
This case demonstrates that successful chiropractic treatment does not depend on force, twisting or a loud crack. The correct technique is the one that is safe, clinically appropriate and acceptable to the patient.
Will One Adjustment Fix the Problem?
Some patients experience immediate relief after one adjustment, but that does not mean the underlying problem has completely healed.
An adjustment may improve movement and reduce pain, but it cannot instantly repair an injured tendon, reverse arthritis or rebuild weak supporting muscles.
Long-term improvement may also require:
- Strengthening exercises
- Mobility work
- Posture changes
- Improved lifting technique
- Workstation modifications
- A gradual return to sport or physical work
The adjustment should create an opportunity for better movement. The patient must then use that opportunity to develop strength, confidence and healthier movement habits.
Questions to Ask Before an Adjustment
If you feel uncertain, ask your chiropractor:
- What do you believe is causing my symptoms?
- Why are you recommending an adjustment?
- Which joint will you treat?
- What will the adjustment feel like?
- What are the expected benefits and relevant risks?
- Are gentler alternatives available?
- What should I do if I feel uncomfortable?
- How will you measure whether the treatment worked?
- What symptoms should I monitor afterwards?
- What exercises should I complete between appointments?
A reputable chiropractor should answer these questions clearly and without making you feel pressured.
What Should You Expect From a Professional Adjustment?
A professional chiropractic adjustment should be explained, targeted and based on an appropriate examination.
You should expect the chiropractor to obtain your consent, position you carefully and select a technique suited to your diagnosis, comfort level, age and health.
You may hear a popping sound, but it does not mean that bones were out of place or that the adjustment was successful. A gentle technique without a crack can still improve movement.
Mild soreness may occur for a day or two, but severe pain or new neurological symptoms are not normal and require prompt attention.
Above all, you should feel involved in your treatment. You have the right to ask questions, request a gentler technique or decline an adjustment completely.
The purpose of an adjustment is not to create a dramatic sound. It is to help restore useful movement, reduce pain where appropriate and support your return to normal daily function.
