What it is

NMT is not a therapy or a technique. Its authors call it a developmentally sensitive, neurobiology-informed approach to clinical problem solving. A certified clinician uses it to assess a person's developmental history and current brain-mediated functioning. The clinician then selects and sequences…

Format

• Part C: rates current central nervous system functioning on 32 brain-mediated functions. These are grouped by their "final common" region: brainstem, diencephalon/cerebellum, limbic, and cortex/frontal cortex. Each is compared with age-typical peers and colour-coded from severe impairment…
• Stage 4: Implementation and dosing. Implementation runs for months, with activities spread through the day across the therapeutic web. There is no session count. Perry & Hambrick describe the work as "long, frequent" and not time-limited, and say that weekly sessions alone are "rarely enough". Case…

Who practises it, and how they are trained or regulated

• Stage 0: Clinician certification. Only certified clinicians use the Metrics. Certification runs in stages. Phase I includes modular learning, book study, study groups, case presentations and monthly Network calls. Later phases and trainer tracks follow, and there is an ongoing fidelity process. One account gives about 90 hours of training. Perry & Hambrick name the shortage of senior clinicians able to lead…
• Outputs: four domain scores: sensory integration, self-regulation, relational, cognitive;
• the Cortical Modulation Ratio (CMR), an index of top-down cortical capacity relative to lower-network dysregulation;

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• allergies, fear of animals, and any history of harming animals.
• asking for introspection during alarm. Do this work only in calm states.
• rigidity. Novelty is reintroduced gradually once regulation improves (4D.3).
• deferrals that become exclusions. Agree a review date and a graded return plan.
• play escalating into dysregulation. Pause the play and return to rhythm (4G.1).

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
