Sensory recovery and retraining

Sensation can sometimes be retrained or supplied through technology, but recovery and substitution must not be confused.

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 sensory recovery and retraining in a declared context without inheriting broader claims.

What the current evidence supports

Selected sensory functions can be retrained or supplied through a configured rehabilitation/device pathway.

How to observe or measure it without overclaiming

Psychophysical thresholds, discrimination, proprioception, task function and embodiment are separate; device-on effects are not biological recovery.

Myth

Restore lost sensation completely

Metric

Modality-specific thresholds, discrimination, task function, device state and user value

Boundary

A reported percept does not establish natural sensation, broad recovery or independence.

Negative and limiting findings

  • The lower-limb stroke pilot found no between-group differences for most outcomes.
  • Home prosthesis evidence involved only two participants and device interruptions.

Claims this evidence cannot support

  • regrow lost nerves through practice
  • restore every sense
  • prosthesis becomes biologically identical
  • sensory games cure stroke

How to learn this Power now.

With a rehabilitation professional, Amir completes coded S/R foam trials and uses vision plus a temperature indicator for a cup instead of trusting impaired heat sensation.

  1. Get readyThe clinician identifies the affected modality and skin/nerve condition and chooses a non-injurious stimulus.
  2. Learn the method8 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. PractiseThe clinician sets frequency and advances from obvious to closer contrasts or to a related daily object only after matched random-order blocks show reproducible discrimination beyond the learner’s first block without skin harm. Compensation remains until functional safety is directly established.
  5. Check progressRecord correct, incorrect and no-response trials for the named modality, confidence, presentation rule, skin condition and use of compensation in a declared functional task.

Authority boundary: Titan teaches the complete method; a qualified person controls the parts that require supervision, clearance, specialist equipment, load, dose or progression. 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; cultural, community-rights or affected-person authority; a restricted safety or legitimacy boundary.

A Power-specific tutorial is available at /tutorials/pwr-058/. It contains a plain-English method, 8 ordered steps, a worked example, right-versus-wrong comparisons, specific mistakes and corrections, practice, measurement, accessibility, stopping rules and evidence. Its supervised mode remains controlling.
