PWR-084 · Touch, Chemosensation & Interoception

Nociceptive discrimination

Pain is not a toughness score. Nociceptive discrimination is real, but deliberate painful training is not authorised.

Canonical Power learning unit · TLU-PWR-084

Using the supplied practice-only routing card, the learner completes two sets of fictional cases by separating event, sensation, pain report, function and uncertainty, then consistently selects EMERGENCY, URGENT, ROUTINE CLINICAL or MONITOR without provoking pain.

Explanation is not permission.

This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.

Complete bounded explanation

What this power means.

Capability to develop or express nociceptive discrimination in a declared context without inheriting broader claims.

What the current evidence supports

Nociceptive discrimination exists, but Titan has no public route for training it; pain and nociception must remain distinct, and stronger tolerance is not assumed to be safer.

How to observe or measure it without overclaiming

Name the controlled stimulus and discrimination outcome while recording the person's pain report separately; stimulus intensity is not pain and neural activity cannot settle lived experience.

Myth

Pain immunity

Metric

Ethically controlled noxious discrimination plus separate pain and harm outcomes

Boundary

Higher tolerance, lower report or altered threshold does not prove safety, health or superior capability.

Negative and limiting findings

  • Noxious temporal-spatial discrimination was worse than innocuous tactile discrimination.
  • Tactile pain interventions are mixed and do not establish nociceptive training.

Claims this evidence cannot support

  • Become pain-proof
  • Condition nerves with repeated injury
  • A high pain threshold proves toughness
  • Infer pain from biomarkers or behaviour

How to learn this Power now.

Using the supplied practice-only routing card, the learner completes two sets of fictional cases by separating event, sensation, pain report, function and uncertainty, then consistently selects EMERGENCY, URGENT, ROUTINE CLINICAL or MONITOR without provoking pain.

  1. Get readyEnd any deliberate pain test and move away from an accidental hazard when that can be done safely.
  2. Learn the method6 concrete steps teach the permitted method from start to finish.
  3. See right and wrong5 comparisons show correct or safer execution beside common wrong or riskier choices.
  4. PractiseFor Set 2, wait at least seven days and do not reread the Set 1 answers. Complete Cards E–H in shuffled order, then reveal the answer strip. Record delayed performance separately. Never use fictional cards to route a real symptom.
  5. Check progressScore event, sensation, pain report, function, uncertainty, controlling sign and category. Any deliberate stimulus is an automatic failure. Score Set 1 and the seven-day Set 2 separately.

Authority boundary: Titan teaches recognition, prevention, safe response and accountable routing without teaching the prohibited act. The method is Power-specific; its actionability follows this treatment.

Current teaching and evidence boundary

The next gate remains visible.

External confirmation is required before higher-authority use because: a clinical, high-risk or regulated configuration; a supervision or non-attempt boundary; a restricted safety or legitimacy boundary.
