Chiropractic adjustments
for injury recovery
A quick, short push by hand to a sore, stiff spinal joint, used alongside exercise to ease neck and back pain after a car crash. With Ryan Lloyd, DC, QME, at our Petaluma office.
Understanding the Treatment
What is a chiropractic adjustment?
A chiropractic adjustment, or spinal manipulation, is a quick, short push by hand to a sore, stiff spinal joint. In the neck it lasts about a tenth of a second. The small joints at the back of the spine part slightly, then close again. The pop you may hear is thought to be gas in the joint fluid, not a bone moving back into place.
Its effects are real but small and short-lived, so we use adjustments as one part of an exercise-based plan, as guidelines for neck pain after a car crash advise.
Before any adjustment, Ryan Lloyd, DC, QME, examines your neck and back: where it's sore, how it moves, your nerves, and warning signs that would rule an adjustment out. We track your recovery with the Neck Disability Index or the Bournemouth Questionnaire, a record that supports medical-legal reports and impairment ratings.
Aimed by Your Exam
We aim at the sore, stiff area your exam finds. The push also reaches neighboring joints, and aiming at one exact level did no better in trials.
A Burst of Signals
Sensors in the joints and muscles fire, and nearby muscles give a brief reflex. Measured effects, like lower sensitivity to pressure, last minutes.
Progress You Can Measure
We track pain and daily life with the Neck Disability Index or the Bournemouth Questionnaire, and watch the trend across visits, not one day.
Matched to You
Most adjustments here are a quick push by hand. Early after a crash, or when that doesn't suit you, we use gentle, low-force techniques.
In slow motion
Inside one neck adjustment
The thrust takes about a tenth of a second. Scroll to slow it down.
First
Find where it's sore and stiff
Before any adjustment, we examine your neck to find where it's sore and stiff, and check for warning signs that would rule an adjustment out.
Preload
A light push first
The hands take up the slack first. In two studies of neck adjustments this push was about 10 newtons or less, roughly the weight of a 2-pound bag of flour. Some chiropractors press harder.
Thrust
One quick push
Then a short, fast push. In studies of neck adjustments, the whole thrust lasts about a tenth of a second.
The pop
Gas, not bones
Bones popping back into place.On X-ray video, the neck's small facet joints part by just under a millimeter during the thrust. As they part, a gas bubble is thought to form in the joint fluid, making the sound; it's been filmed in knuckles. One thrust often makes several pops, and a pop isn't needed for an adjustment to help.Response
Nerves and muscles answer
The muscles near the joint usually give a brief reflex, within a fraction of a second. In lab animals, a fast push made the back muscles' stretch sensors fire far more than a slow push did.
Afterwards
Small, short-lived changes
Sensitivity to pressure can ease slightly for a few minutes, though a convincing pretend adjustment may do the same. Over the first few visits, about half of people notice some soreness, stiffness or a headache, usually mild to moderate and mostly gone within a day. Guidelines for neck pain after a crash pair adjustments with exercise, and so do we.
The PI Approach
How we use adjustments for injury recovery
Where adjustments fit after a crash: what guidelines advise, the window of relief they give, what you might feel, and how we measure change.
The Plan After a Crash
For neck pain after a car crash, the guideline written for traffic injuries starts with checks for serious injury, reassurance that most people improve, and advice to stay active. For the first three months it recommends range-of-motion exercise and education, and an adjustment or gentler mobilization can be added to that exercise. In the first weeks, we use gentle, low-force techniques. No trial has tested adjustments on their own after whiplash, so we use them as one part of that plan, not instead of it.
A Window to Move
Right after an adjustment, many people with neck pain feel less pain and tenderness and can turn their head further. That window of relief is a good time for stretches and exercises, so we follow adjustments with exercise you can build on.
What You Might Feel
Over the first few visits, about half of people notice some soreness, stiffness, a headache or tiredness after an adjustment. In a study of over 1,000 new patients, most reactions began within four hours and about three in four were gone within a day. Serious problems are rare. A tear in a neck artery is rare but serious and often starts with neck pain or a headache; the American Heart Association advises that patients be told about the link before a neck adjustment. Tell us how you felt after each visit.
Measuring Real Change
We track your recovery with a standard questionnaire about pain and daily life: the Neck Disability Index or the Bournemouth Questionnaire. Both have been tested in people with neck pain, and each has a published threshold for a real change; on the Bournemouth, a drop of about 13 points. After each adjustment we also recheck by hand how the joint moves: that check guides the visit, and the questionnaires track progress across visits.
Conditions
Conditions we treat with adjustments
Adjustments are one part of care for these injuries. Here is what research shows for each, including where it hasn't been studied after a crash.
Whiplash
Guidelines for neck pain after a crash start with reassurance, staying active and range-of-motion exercise, and an adjustment or gentler mobilization can be added to that exercise. No trial has yet tested adjustments on their own after whiplash.
Learn more →Neck Pain
In adults with neck pain for 2 to 12 weeks, a course of adjustments eased pain about as much as home exercise with advice, and more than medication. Several studies saw neck movement rise a few degrees right after an adjustment. These studies weren't in crash patients.
Learn more →Back Pain
For new low back pain, adjustments eased pain by about 1 point on a 0–10 scale over the first six weeks. For long-lasting back pain, they helped about as much as other recommended care. Guidelines include them alongside exercise.
Learn more →Radiculopathy
For leg pain from a disc bulge, one trial found 55% of people free of leg pain after real adjustments, against 20% after a sham; added to home exercise, leg pain was better at 12 weeks but not at a year. For arm pain from the neck, the evidence is very limited. We recheck your nerves as care goes on.
Learn more →Headaches
For long-lasting headaches that come from the neck, 18 visits of neck and upper-back adjustments over six weeks halved headache days in one trial, about 3 fewer every four weeks than light massage. For headaches after a head injury, research is too thin to say. We check for other causes first.
Learn more →TMJ Dysfunction
For jaw (TMJ) pain, treatment to the upper neck eased pain by about 2 points on a 0–10 scale more than a sham in the short term. The evidence is limited and not from crash patients.
Learn more →Chest & Rib Pain
Chest pain after a crash needs a medical check first. For chest-wall pain that doctors have found isn't from the heart, chiropractic care including adjustments helped more than self-care at 4 and 12 weeks, but not at a year. Rib injuries from seatbelts haven't been studied.

What to expect during treatment
From your first exam to your last visit, we recheck your progress and adjust the plan.
Initial Evaluation
A history and exam: where it hurts, how you move, your nerves, and warning signs that would rule an adjustment out, plus a questionnaire about pain and daily life. At 3100 Lakeville Highway in Petaluma, just off Highway 101.
Treatment Plan
A plan built around exercise and staying active, with adjustments added when they suit you: gentle, low-force techniques in the first weeks, quick adjustments by hand later. Visits are spaced to what you need.
The Adjustment
A quick, short push by hand; in the neck it's over in about a tenth of a second. You may hear a pop or not; results were the same either way. If a quick push doesn't suit you, we use a gentler technique.
Afterwards
Over the first few visits, about half of people notice some soreness, stiffness or a headache; it usually starts within hours and mostly fades within a day. Tell us at your next visit.
Ongoing Assessment
We recheck your progress at every visit and repeat your questionnaire as care goes on, until you've recovered or reached maximum medical improvement, a medical-legal judgment these records support.
