Are there clinical trials related to Christian Goodman work?

1) Are there clinical trials of Christian Goodman–branded programs?

Short answer: Nonone that are indexed in major medical databases or trial registries. Searches of PubMed/Medline for “Christian Goodman” as an author and for “Blue Heron Health News” as a trial sponsor or intervention do not return randomized or registered clinical trials of his branded programs. Likewise, press and marketing materials for Blue Heron spotlight consumer programs and testimonials rather than registered trials. In other words, there is no peer-reviewed, randomized clinical trial that tests “Christian Goodman’s [program name]” as a formal, named intervention. blueheronhealthnews.orgGoogle Sites

That absence does not mean related techniques are unstudied. Several categories of exercises central to his programs have, in fact, been evaluated by independent researchersjust not as “the Christian Goodman program.” Below is the state of the evidence in those domains.

2) Oropharyngeal (mouth & throat) exercises for snoring and mild–moderate obstructive sleep apnea (OSA)

This is the area with the clearest clinical-trial support among Goodman-adjacent techniques.

• A randomized controlled trial (Guimarães et al., 2009) in the American Journal of Respiratory and Critical Care Medicine showed that 3 months of targeted upper-airway (oropharyngeal) exercises significantly reduced the apnea–hypopnea index (AHI) and improved symptoms in adults with moderate OSA. The study was registered (ClinicalTrials.gov NCT00660777). ATS JournalsPubMed

• A separate randomized trial (Ieto et al., 2015) in CHEST found that 3 months of daily oropharyngeal exercises reduced objectively measured snoring frequency by ~36% and snoring power by ~59% among primary snorers/mild OSA vs. a control regimen. Registered as NCT01636856. PubMedScienceDirectjournal.chestnet.org+1

• Reviews and overviews in reputable outlets summarize that myofunctional/oropharyngeal therapy can produce clinically meaningful improvements in snoring and modest AHI reductions in mild–moderate OSA, with effectiveness tied to consistent daily practice over 2–3 months. jwatch.org

What this means: There are RCTs supporting the category of exercises (tongue, soft palate, and oropharyngeal muscle training) frequently described in Goodman’s snoring/sleep-apnea materials. But these trials did not test a branded “Christian Goodman” protocol; they tested clinically designed myofunctional regimens under academic teams. For moderate–severe OSA, CPAP and other guideline therapies remain standard; exercise regimens are best viewed as adjuncts or alternatives in selected patients, not universal replacements. ATS JournalsPubMed

3) Slow, paced, or device-guided breathing for blood pressure

Goodman’s blood-pressure content often features relaxation and slow breathing. Here, the clinical literature is mixed and quality-sensitive:

• Early device-guided breathing studies (e.g., with the RESPeRATE device) suggested small BP reductions and led to FDA clearance for reducing stress/lowering BP; however, later independent analyses note modest effects and methodological concerns (e.g., control conditions, sponsorship). PMCMayo Clinic

• A more recent systematic review and meta-analysis (2022) that separated device-guided slow breathing (DGSB) from non-device slow breathing (NDGSB) found that higher-quality, independent, sham-controlled trials often showed limited or inconsistent BP reductions, casting doubt on robust, durable antihypertensive effects from breathing alone. PubMedWiley Online Library

• Individual RCTs with ambulatory BP monitoring have reported no significant difference vs. control despite slowed respiration, underscoring the variability in outcomes when tight controls are used. PubMed

What this means: Slow breathing is physiologically plausible and generally safe, and some people experience small BP drops, but the best-quality evidence does not support large, reliable, stand-alone antihypertensive effects. As such, any program (branded or otherwise) claiming major BP normalization from breathing alone is going beyond what rigorous trials currently show. PubMed

4) Dizziness/vertigo: vestibular rehabilitation and related exercises

Many alternative programs (and some Goodman materials) propose head/eye/neck/balance exercises for dizziness. In clinical practice, the relevant evidence base is vestibular rehabilitation therapy (VRT):

• Cochrane reviews conclude there is moderate to strong evidence from multiple RCTs that vestibular rehabilitation improves symptoms and function in unilateral peripheral vestibular dysfunction (e.g., after vestibular neuritis). cochranelibrary.comPubMedPMCCochrane

• For benign paroxysmal positional vertigo (BPPV), the first-line, evidence-based therapy is a canalith repositioning maneuver (e.g., Epley). VRT can be useful for residual balance problems or chronic dizziness in certain subgroups, but repositioning is the primary intervention when BPPV is the diagnosis. cochranelibrary.comCochrane

What this means: There are strong trials for clinical VRT protocolsagain, not for a “Christian Goodman”-branded routine. If a consumer program mirrors established VRT principles and is used for the right diagnosis, it aligns with evidence; if it replaces repositioning maneuvers in classic BPPV, it departs from best-practice care. cochranelibrary.com

5) Other domains sometimes referenced in alternative programs

Some consumer materials touch on topics like tinnitus, anxiety, or posture-related pain. Briefly:

• Tinnitus: The intervention with the most consistent RCT support for reducing distress (not the perception of sound itself) is cognitive-behavioral therapy (CBT), delivered in-person or digitally. Musculoskeletal/“somatic” tinnitus protocols (jaw/neck–directed) have promising but preliminary evidence for select subtypesnot universal relief. (High-quality systematic reviews remain cautious.)

• Anxiety/stress: Multiple RCTs show that breath-focused practices and mindfulness-based programs can reduce stress markers and anxiety symptoms; these are adjunctive, not curative for all anxiety disorders.

• Posture/back pain: Clinical guidelines recommend exercise and movement-based care as first-line for many cases of nonspecific chronic low back pain; structural pain etiologies may require additional medical management.

(These points synthesize broad guideline/trial trends; since they’re tangential to “Goodman-related trials” specifically, I’m keeping them brief and uncited here.)

6) So… are there clinical trials “related to” Goodman’s work?

Yes, if we mean “related by technique,” and No, if we mean “his exact branded programs tested.”

• Direct, branded trials of “Christian Goodman” programs: None identified in PubMed or in the way reputable trials are normally registered and reported. Marketing and third-party write-ups describe the programs but do not link to registered trials testing the package itself. blueheronhealthnews.orgGoogle Sites

• Closest clinically tested techniques that mirror his themes:

  • Oropharyngeal/myofunctional exercises for snoring and mild–moderate OSA → Supported by RCTs and summarized in respected journals; benefits are modest–moderate, adherence-dependent, and adjunctive rather than a universal CPAP substitute. ATS JournalsPubMed

  • Slow/paced breathing for hypertension → Mixed evidence; high-quality independent trials/meta-analyses show small or inconsistent BP changes, so it’s not a stand-alone antihypertensive therapy on par with medications or comprehensive lifestyle programs. PubMed

  • Vestibular rehabilitation for dizziness (non-BPPV vestibular dysfunction) → Supported by multiple RCTs/Cochrane; for BPPV, repositioning maneuvers remain first-line. cochranelibrary.com

7) Practical implications if you’re considering a Goodman-style program

1. Match the technique to the diagnosis.
   If snoring/mild OSA is your issue, oropharyngeal exercises have trial support; if you have moderate–severe OSA, guideline care (e.g., CPAP) is still the backbone, with exercises as a possible adjunct. For BPPV, seek canalith repositioning first; generic “neck/balance” routines are not a substitute. For hypertension, slow breathing may be supportive but insufficient by itself. ATS JournalsPubMed+1cochranelibrary.com

2. Expect benefits to be dose- and adherence-dependent.
   The positive airway-exercise trials typically required daily practice over 2–3 months; sporadic use blunts outcomes. PubMed

3. Be skeptical of “clinically proven” claims attached to a brand name.
   Unless a program has a registered, peer-reviewed trial of that exact protocol, “clinically proven” usually means “inspired by techniques that have some evidence”not that the commercial package itself was tested head-to-head. blueheronhealthnews.org

4. Use clinicians as allies, not obstacles.
   A sleep physician, vestibular therapist, or hypertension specialist can help you combine safe self-care with evidence-based medical treatments, maximizing benefit and avoiding delays in care.

8) Balanced conclusion

• There are no peer-reviewed randomized clinical trials of Christian Goodman–branded programs (as named products) that I can locate in the major medical literature or reputable trial registries. His and Blue Heron’s public materials promote consumer-facing programs and do not cite registered trials testing the full branded packages. blueheronhealthnews.orgGoogle Sites

• However, several techniques that resemble the core of his approachmost notably oropharyngeal exercises for snoring/mild OSAdo have clinical-trial support and appear in respected journals with trial registration numbers (e.g., NCT00660777, NCT01636856). These studies report real but bounded benefits that depend on consistent practice and are adjunctive for many patients. ATS JournalsPubMed

• For blood pressure, the best-controlled evidence on slow/device-guided breathing shows small or inconsistent effects, indicating it is not a robust stand-alone therapy for most people, even though it’s low-risk and physiologically plausible. PubMed

• For dizziness/vertigo, vestibular rehabilitation is strongly supportedbut as clinical VRT protocols for the right diagnoses; and BPPV specifically calls for repositioning maneuvers as first-line. cochranelibrary.com

If you’re evaluating a Goodman-style program, the most evidence-aligned path is to treat these methods as complementary strategiesespecially in domains where trials exist for similar techniquesand to pair them with standard, guideline-based care when your diagnosis warrants it. That way, you capture the potential upside of accessible, self-directed practice without sacrificing the proven benefits of conventional therapy.
