Episode Transcript Excerpt

HOST (Amin Said): The question I always get from patients is — is chiropractic actually backed by science? Dr. Dick, you're a published researcher. How do you answer that?

DR. DICK: The evidence for spinal manipulation is actually quite strong. Systematic reviews, Cochrane reviews — the data on spinal manipulation for musculoskeletal conditions is real. Where chiropractors get into trouble is overclaiming. The moment you start saying manipulation cures conditions that aren't in the literature, you lose the credibility you built with what is documented. I publish research specifically to strengthen that evidentiary base. Eight peer-reviewed publications. Every one is a documented, measurable clinical outcome. That's the answer to 'is it backed by science' — show the work.

HOST: What about laser therapy — photobiomodulation. There's a lot of buzz around it. Does the evidence support it?

DR. DICK: There's legitimate mechanism here — we understand how photons interact with mitochondria, cytochrome c oxidase, the cellular energy cascade. The basic science is solid. The clinical evidence is more mixed. It works for some conditions, in some patient populations, at specific parameters. The problem is that devices get sold to practices with promises that outpace the evidence. I want to see the wavelength, the joules per centimeter squared, the tissue depth, the specific condition being treated. Without that, you're guessing.

HOST: Spinal decompression — when does it actually help?

DR. DICK: Decompression works when you have the right patient: confirmed discogenic pathology, contained herniation, radiculopathy, and a spine that can tolerate the distraction. It doesn't work for everyone, and it's not a first-line intervention for general back pain. The mistake practices make is applying it broadly because they paid for the equipment. Clinical discernment matters more than the device. If you can't articulate why this patient needs this modality, you shouldn't be billing for it.

Frequently Asked Questions

Is chiropractic care backed by science?

The evidence for spinal manipulation is strong. Systematic reviews and Cochrane reviews document real clinical benefit for musculoskeletal conditions. Where the profession loses credibility is in overclaiming — asserting that manipulation treats conditions beyond what the published evidence supports. Evidence-grounded practice, documented with peer-reviewed research, is the standard that separates credible from non-credible claims.

Does laser therapy (photobiomodulation) work for chiropractic patients?

There is legitimate biological mechanism — photons interacting with mitochondria and cytochrome c oxidase have real effects at the cellular level. The clinical evidence is more mixed. Effectiveness depends on wavelength, joules per centimeter squared, tissue depth, and the specific condition being treated. Clinical discernment matters more than equipment investment.

Which patients benefit most from spinal decompression?

Spinal decompression is most effective for confirmed discogenic pathology — contained disc herniations with radiculopathy — in patients whose spine can tolerate the distraction force. It is not a first-line intervention for generalized back pain, and it should not be applied broadly to justify equipment costs. Each decompression prescription should be tied to a specific structural finding.
