Emotion Code

Founder and first publication

The method is associated with Bradley Nelson, whom the sponsoring organisation Discover Healing describes as its founder and as the author of The Emotion Code, The Body Code and The Belief Code. The same page lists his credential as D.C. (retired), which denotes a chiropractor. It gives no account of when or how he developed the method, and no dates.

A library catalogue record gives 2007 as the first year of publication of the book The Emotion Code, with later editions listed in 2011 and 2019. The 2019 editions include a hardcover from St. Martin's Essentials, an audiobook and UK editions. This is a bibliographic record only. The sources reviewed do not say whether the method was taught before the book appeared or how it changed between editions.

Ideas the method draws on

The authors of the only published study of the method state that it rests on several beliefs: an energy body, Chinese acupuncture meridians, distant prayer and intention, the use of magnets to release energy, and muscle testing derived from applied kinesiology. They add that the methodology as a whole is not grounded in common conceptions of scientific causality. This is the study authors' own account and not an independent history.

A review by applied kinesiology practitioners describes that system as an attempt to assess structural, chemical and mental aspects of health by manual testing of muscles combined with other methods. The same review notes that many derivatives of applied kinesiology exist and advises caution about those that lack its essential features. Whether the Emotion Code counts as a derivative in that sense is not addressed in the sources reviewed.

Related branded programmes

Discover Healing presents the Emotion Code as the first of three certification levels, followed by the Body Code and the Belief Code. The Heart-Wall is described on the method's own pages as a related concept with its own book. None of the pages reviewed gives dates for these additions, so the order in which the programmes were developed cannot be stated from these sources.

A branded name

Emotion Code is the name of a specific method, written with a registered trademark symbol on the sponsor's pages alongside Body Code and Belief Code. It is not a general term for emotional release or for therapies that work with feelings. Readers searching for emotional processing in psychotherapy or other body-based approaches will find different practices under different names.

Trapped emotions

The sponsor's pages describe a trapped emotion as the energy of a past emotion that becomes lodged in the body and is said to affect physical, mental, emotional and spiritual health. The 2021 study describes the founder's account as congested energetic masses in an etheric energy body. This is the method's own vocabulary. None of the independent sources reviewed uses or defines the term.

Muscle testing, applied kinesiology and proxy testing

Practitioners of the method describe muscle testing as applied kinesiology used to obtain yes or no answers from the body. In the research literature, manual muscle testing is a way of grading muscle strength, and a challenge is an added stimulus such as holding a substance or a thought while strength is tested. A 2025 systematic review separates testing without a challenge from testing with nonmusculoskeletal challenges. Proxy testing means that the practitioner tests their own muscles on behalf of a client at a distance, which the 2021 study calls the least scientifically supported element of the method.

Session sequence reported in the 2021 study

In the 2021 study, each session was given by a certified practitioner and began with the client and practitioner connecting through prayer and intention. Muscle testing was done on the client in person or on the practitioner as a proxy. Using a chart of emotions and yes or no questions, the practitioner identified one emotion at a time and the age at which it was said to have become trapped, and asked whether anything else needed to be known before release.

Release was attempted by passing a magnet along the meridian running from the base of the spine to the crown of the head, with the intention of releasing the emotion, after a further muscle test confirmed it could be released now. The study reports a 48-hour pause between sessions and after-session instructions to drink water and rest. The number of sessions varied between participants. The sponsor's page adds that five to ten emotions can often be identified and released in a twenty-minute session.

Practitioners and training

Certification is run by Discover Healing. Its page states that the courses can be completed entirely online over a six-month timeline, that Level 1 has no prerequisites, that students record hands-on practice sessions in a portfolio, and that students must be 18 or older. The organisation reserves the right to refuse certification. Its FAQ says that certification requires documented practice sessions on humans and animals, and none of the pages lists a medical or psychological qualification as a prerequisite.

The sponsor states that practitioners can work with clients anywhere in the world by proxy testing. The sources reviewed identify no independent accreditation body, professional register or external training standard for the method, and no statutory regulation or training standard was found.

Claims made by the method's proponents

The sponsor describes the method as a way to discover and release trapped emotions so that healing in the body is faster and more efficient. Its FAQ states that the methods are not meant to treat disease but to remove underlying imbalances so that the body is in the best position for its own healing. A sponsor article on how the method works says it may help prevent emotional and physical discomfort.

A sponsor article on pregnancy states that trapped emotions may affect fetal development and describes distance sessions using muscle testing and meridian work. No source reviewed tests these statements, and they are recorded here as claims only.

Uses that have been studied

The one published study of the method examined self-reported depression, anxiety and post-traumatic stress symptoms in adults who had started sessions. The sponsor's research page also lists a preliminary before-and-after study of a protocol for morning sickness, a mouse study and forthcoming work on inherited trapped emotions and low back pain, and marks these as not peer reviewed. The sources reviewed do not document why people seek the method in everyday life.

The published study of the method

Gelb and colleagues (2021) analysed 146 adults, 132 of them women, recruited by Emotion Code practitioners from clients beginning sessions for the first time. Participants completed the PCL-5 (post-traumatic stress), Zung anxiety scale and PHQ-9 (depression) questionnaires before and after treatment. The authors report significant decreases on all three measures, larger among those who began with higher scores.

The design had no control group in the analysis: a control group was collected but discarded because it differed in demographics, collection method, sample size and pricing. The authors state that outcomes were self-reported, that causal effects cannot be concluded, that a placebo effect has not been ruled out, and that randomised replication is needed. The work was funded in part by Discover Healing, and the sponsor's research page quotes 158 participants, not 146.

PubMed searches for the method's name and for trapped emotions combined with muscle testing returned no further studies of the method, and the sponsor lists no other peer-reviewed study. No randomised trial or systematic review of the Emotion Code was found.

Muscle testing as a diagnostic or detection tool

A 2025 systematic review of manual muscle testing in applied kinesiology included 7 of 8,720 records. Reliability ranged from nonexistent to very strong. Testing with nonmusculoskeletal challenges showed nonexistent reliability and was not recommended for clinical use, whereas testing without challenges was moderately to very reliable for some muscles. A 2022 study of 38 people reported good reliability of the test for differences in gluteus medius strength; grading strength differs from detecting emotions.

A double-blind randomised study of 51 participants (151 sets of trials) asked kinesiologists to identify which of two vials contained a toxic solution by muscle testing. They were correct in 53 per cent of sets, consistent with chance, and a dynamometer arm also performed at chance. The authors concluded that applied kinesiology has not shown itself to be a reliable diagnostic tool for health decisions. A review by applied kinesiology practitioners states that the effectiveness of challenge and therapy localisation is not yet established in peer-reviewed research. Neither study tested emotions.

Proxy testing, magnets and the ideomotor effect

The 2021 study states that the use of magnets as done in this method has not been studied or verified. The US National Center for Complementary and Integrative Health states that research does not conclusively support static magnets for pain relief, citing a 2021 review of seven studies of which four showed improvement and three did not.

The ideomotor effect is the term for unconscious muscle movements caused by thinking of a motion. In one study, people who asked a hand-held pendulum whether a target letter was present were correct 53 per cent of the time, compared with 57 per cent when answering aloud. The study did not examine muscle testing, so any link to the method is an inference.

Reported effects

In the 2021 study, participants were told they might have processing symptoms, such as headache, fatigue or feeling emotional, which would pass within 48 hours. No adverse-event data were reported in the sections of the paper reviewed, and the sources reviewed contain no systematic reporting of harms. Lack of reporting does not establish that none occur. The sponsor's pregnancy article describes the method as safe for the baby because magnets or fingers are used, a statement no independent source reviewed supports.

Using muscle testing to identify illness

The British Dietetic Association states that there is no scientific evidence that kinesiology can accurately diagnose food allergies and lists it among alternative tests that are not scientifically validated. The 2025 systematic review recommended against clinical use of muscle testing with nonmusculoskeletal challenges. A muscle test result should therefore not be used to decide whether a person has an allergy or illness, or to change a diet, medicine or treatment.

The sponsor states that the method is not meant to treat disease, which is consistent with using it only alongside, never in place of, assessment and treatment. Magnets also carry their own cautions: the national centre advises people with pacemakers or insulin pumps, those who are pregnant and those due an MRI scan to take care with magnetic devices. That guidance covers static magnets for pain, and its application to a magnet passed over the spine and head is an inference.

Training, cost and when to seek care

Because certification is awarded by the sponsor and requires no clinical background, a certificate says little about a practitioner's ability to recognise mental or physical illness. People can ask what training a practitioner has, what they claim the method can do, and whether they will say when a medical or psychological assessment is needed.

Thoughts of self-harm, severe or persistent low mood, panic, new physical symptoms or distress after a session are reasons to contact a doctor, a mental health professional or an emergency service. The method is not a replacement for assessment or for prescribed treatment.
