What Your Chiropractor Says Before the Adjustment Affects How You Feel After
A 2026 study found that the words your provider uses right before a spinal manipulation predicted 24-hour pain relief better than your own pre-existing beliefs about chiropractic care.
The 60-second answer
A 2026 randomized trial took 66 patients with chronic low back pain and gave them all the same spinal manipulation. The only thing that changed was a short message before the adjustment, either positive, neutral, or negative. Twenty-four hours later, the patients who heard the negative message reported worse pain. The positive group reported better pain. Their pre-existing beliefs about chiropractic? Did not predict outcomes. What the provider said in the moment did. The takeaway for patients: the explanation you get before an adjustment is part of the treatment, not just the introduction.
What the Study Did
Researchers at John Paul II University in Poland, working with collaborators in Spain and Italy, took 66 young adults with chronic non-specific low back pain and randomized them into three groups. Everyone got the same lumbar spinal manipulation. The only difference: each group heard a different short message just before the adjustment.
- Positive group: heard a message framing the manipulation as effective and well-tolerated.
- Neutral group: heard a procedural description with no judgment of effect.
- Negative group: heard a message that included possible discomfort or limited effect.
Outcomes were measured at three time points: just before the adjustment, immediately after, and 24 hours later. The two outcomes were a numeric pain rating from 0 to 11 and a pressure pain threshold test on the lumbar spine.
The researchers also asked patients about their pre-existing expectations, their attitudes toward manual therapy, and whether the treatment met their expectations afterward. Then they ran a regression model to figure out which of these factors best predicted pain reduction at 24 hours.
The Surprising Result
The patient's pre-existing beliefs and expectations did not predict outcomes. Whether someone walked in expecting to feel better, walked in skeptical, or walked in neutral, those starting attitudes did not show up consistently in the data.
What did predict outcomes? The verbal framing group. That was the only factor the regression model retained.
- Negative framing predicted higher 24-hour pain.
- Positive framing predicted lower 24-hour pain.
- The model explained 26 percent of the variance in 24-hour pain ratings, which is meaningful for a single intervention with one short message.
In plain English: the message right before the adjustment carried more weight than what the patient already believed walking in.
Why This Should Not Be Surprising (Even Though It Is)
Pain is not just a signal from your tissues. It is a prediction your nervous system makes based on what it expects, what it has learned, and what your provider just told you. The expectancy and placebo literature has been showing this for decades, mostly in laboratory settings with sugar pills.
What the Zaworski study adds is real-world clinical data, in a real clinical procedure, where the only manipulated variable was the words. No fake pills. No theatrical setup. Just the same hands-on treatment with three different brief explanations.
If you are a chiropractor, that finding is humbling and useful. The hands-on technique is one ingredient in the outcome. The explanation that surrounds it is another. Both matter.
If you are a patient, the practical implication is that the way your provider talks to you is part of the care, not just the customer service. A provider who explains what is going to happen, in plain language, with a calibrated tone, is delivering treatment ingredients, not just bedside manner.
The framing question gets sharper when a treatment carries a four-figure price tag. A 2026 meta-analysis of 15 randomized trials (Pei et al., n=740) tested platelet-rich plasma injections for low back pain, where marketing language and patient expectancy are doing real work on the perceived outcome. My read on the PRP meta-analysis separates the honest short-term signal from the inflated long-term claims.
What to Listen For at a Chiropractic Visit
Based on the Zaworski findings and the broader expectancy literature, here is what good provider communication sounds like before a manipulation. None of this is theater. All of it is part of what shapes your nervous system's response.
1. A clear description of what is going to happen
"I am going to set you up on your side, place my hand here on your hip and shoulder, and apply a quick directional thrust. You may hear a pop or a click. That is the sound of synovial fluid in the joint, not bone."
Patients who know what to expect do better. The brain's prediction machinery has less work to do when it is not bracing for the unknown.
2. An honest expected response
"Most patients feel a release of tension immediately. Some feel a brief soreness for a few hours, similar to what you feel after a workout. By tomorrow morning, most people feel either the same or better than today. If you feel worse for more than 48 hours, call us."
That kind of language sets a realistic expectation. It does not over-promise. It does not under-promise. It teaches the patient how to interpret their own response over the next day, which is when most of the change happens.
3. A reason for the technique choice
"For your case, I am picking a side-posture lumbar adjustment because the joint that is restricted is in your low back at L4-L5 and the side-posture setup gives me the best mechanical advantage with the least force."
Patients who understand WHY a specific technique was chosen for their specific case rate care higher and do better. The information itself is treatment.
4. Calibrated tone
Not over-confident. Not hedged into oblivion. The Zaworski study did not use scripted scary language for the negative group, just neutral framing of possible discomfort or limited effect. Even that was enough to predict worse outcomes. So a provider who hedges every sentence with "this might not work" is not doing you a favor. They are setting your nervous system up to confirm their hedge.
What Bad Provider Communication Sounds Like
Three patterns that show up in busy practices and should be a flag for you as a patient.
- Silent adjustment. Provider walks in, sets you up, adjusts, walks out. No explanation before, no explanation after. The Zaworski data suggests this is leaving outcome on the table.
- Over-warning. Provider lists every possible adverse outcome before any positive framing. Negative framing predicts worse outcomes. Patients deserve safety information AND a realistic expectation. Both can fit in 30 seconds.
- Sales-coded language. Provider frames every visit as a step in a 24-visit prepaid plan. The framing is no longer about the visit's actual mechanism. It becomes about commitment to the package, which is not what helps your nervous system update.
Why This Matters in Tulsa Specifically
Tulsa has dozens of chiropractors, and the variation in communication style is huge. Some practices run high-volume visits where the doctor is in and out in under five minutes. There is no time for a calibrated explanation. The Zaworski data tells you that low-touch model is missing a real treatment ingredient.
At Vanguard Chiropractic in Brookside, the standard visit includes a brief check-in on what changed since the last visit, a quick explanation of what I am about to do, the adjustment itself, and a quick interpretation of what to expect over the next 24 hours. That structure is not customer service flavor. It is part of how the visit works.
What to Ask Your Chiropractor Before the First Adjustment
Three questions to ask any provider, not just at Vanguard Chiropractic. The answers tell you whether you are in good hands before the hands ever touch you.
- "What are you about to do, and why?" A real provider can describe the technique and the reason in plain language.
- "What should I expect to feel for the next 24 hours?" A real provider can give you a realistic range, including the possibility of brief soreness or feeling the same.
- "What would tell us this isn't working?" A real provider has a clear definition of when to switch approach. Vague answers are a flag.
If a chiropractor cannot answer those three questions in plain language, that is information. Walk away.
Walk in. Get a real explanation.

Frequently Asked Questions
Does the chiropractor's explanation actually affect how I feel?
According to a 2026 randomized trial, yes. Researchers gave 66 patients the same spinal manipulation but varied the verbal framing before treatment. The framing predicted 24-hour pain levels better than the patients' own pre-existing beliefs about chiropractic. Negative framing predicted worse pain. Positive framing predicted better pain.
Is this just a placebo effect?
It is part of the same family of mechanisms as expectancy and placebo, but the Zaworski study held the actual treatment constant. Everyone got the same manipulation. So the verbal framing did not replace the treatment, it modulated how the body responded to it. The treatment matters. The framing matters too. Both are real.
What should a good chiropractor say before adjusting me?
A clear description of the technique, an honest range of expected response over the next 24 hours, the reason this technique was chosen for your specific case, and a calibrated tone that is neither over-confident nor over-warning.
Should I worry if my chiropractor does not explain things?
Worry is too strong. But the silent-adjustment style is leaving outcome on the table. Ask the three questions: what are you about to do and why, what should I expect to feel for 24 hours, what would tell us this is not working. If a provider cannot answer those in plain language, consider another option.
Does this finding apply to all chiropractic care or just spinal manipulation?
The Zaworski study specifically examined lumbar spinal manipulation. The broader expectancy literature suggests similar effects apply across most musculoskeletal interventions, but the strongest direct evidence at this point is for the manipulation context. The general principle, that provider communication shapes outcomes, applies broadly.
Can negative framing actually make pain worse?
The data say yes, in the short term. Negative framing in the Zaworski trial predicted higher 24-hour pain ratings even when the same treatment was delivered. That is part of why responsible providers avoid scripted scary language while still being honest about safety information.
