Pain researchProtocol review

Movement-evoked pain analysis for guarding and function studies

Measure movement behavior during pain research tasks while keeping self-report, clinical context, and rater interpretation central.

Study measures

What the camera can measure

These outputs are designed for study comparison, rater review, and statistical analysis. They are not diagnostic claims.

Movement avoidance

reduced range, slow initiation, or early task stop

Guarding event

protective posture, hand placement, or altered movement path

Task timing

start latency, movement duration, pause, and completion

Facial action review

visible facial keypoints during approved tasks

Study setup

Build the task around your protocol

ConductVision works best when the task, camera setup, annotations, and export fields are defined before the first participant visit.

Task presets

  • sit-to-stand
  • trunk flexion
  • reach task
  • walk test
  • facial expression review

Researcher annotations

  • self-reported pain
  • task instruction
  • movement stop
  • guarding review
  • medication timing

Export fields

  • task duration
  • range proxy
  • guarding events
  • pause timing
  • paired self-report

Camera setup

Full-body camera for movement tasks; optional face view only when approved by consent and protocol.

What is established

Movement-evoked pain, guarding, facial expression, and function tasks are studied alongside self-report and clinical measures.

What ConductVision quantifies

ConductVision measures visible movement and expression events for review, pairing each output with protocol annotations.

What still needs validation

Pain intensity, causality, and clinical meaning require self-report, clinical context, and study-specific validation.

Data export

Reviewable data for analysis teams

Exports are built for study notebooks, statistical analysis, and rater review. The video remains available for audit when the protocol allows it.

CSV task summary by participant, visit, and session
Frame-level landmark coordinates with confidence values
Event timestamps for starts, stops, repetitions, pauses, and task phases
JSON review files for overlays, researcher notes, and audit history
Evidence

Scientific context for the task family

These links point to the measurement areas researchers commonly use when validating a protocol.

Research-use measurement note

ConductVision outputs are research-use measurements unless a customer has completed their own clinical validation, regulatory review, and intended-use controls. The study team remains responsible for consent, privacy, camera calibration, rater review, and clinical interpretation.
