Workflow

Run a neuropathic pain study

A workflow for linking model induction, behavioral endpoints, controls, and analysis in neuropathic pain studies.

Decision summary

Use this workflow when a study needs a planned sequence from model induction to behavioral readouts. Mechanical sensitivity is usually one part of the evidence package, not the entire claim.

Before model	Baseline mechanical threshold and relevant motor or health checks.
After model	Scheduled endpoint collection with identical acclimation and trial conditions.
Companion readouts	Thermal latency, motor status, body weight, wound or paw condition.
Decision point	Pause interpretation if motor or health changes can explain response shifts.

Use when

The study has a nerve injury, chemotherapy, inflammatory, or other neuropathic pain model.
Baseline and post-model behavioral readouts can be scheduled consistently.
The analysis plan separates mechanical, thermal, motor, and welfare observations.

Do not use when

The model or outcome is acute nociception only.
The study cannot support baseline measures, blinding, or consistent test timing.

Caveats

Mechanical hypersensitivity alone does not identify mechanism.
Testing order and repeated exposure can alter response expression.
Post-surgical or disease-related motor deficits can mimic endpoint changes.

Reporting checklist

State model, timing, and baseline schedule.
Define behavioral endpoints and apparatus.
Report blinding, randomization, and exclusions.
Report welfare observations and motor checks.
Provide calculation methods for thresholds or response probabilities.
