Large Language Models for Epidural Stimulation Electrode Mapping in Spinal Cord Injury

8 settembre 2026 aggiornato da: Görkem Açar, Istanbul Gelisim University

AI-Assisted Electrode Contact Configuration Mapping for Epidural Electrical Stimulation in Spinal Cord Injury: A Comparative Evaluation of Large Language Models

This observational and methodological study aims to compare the performance of large language models in generating electrode contact configuration recommendations for epidural electrical stimulation in spinal cord injury.

Five standardized synthetic spinal cord injury scenarios will be presented to four large language models: ChatGPT-4o, Claude, Grok 3, and Gemini 2.5 Pro. Each model will receive the same standardized prompt. The generated responses will be anonymized and evaluated independently by experts with experience in spinal cord injury rehabilitation and epidural electrical stimulation.

The responses will be assessed in five main areas: clinical accuracy, technical feasibility, safety awareness, consistency with current clinical guidance, and completeness of the response. Agreement between expert evaluators will also be examined.

No real patients, human participants, clinical interventions, or personal health data are included in this study. The study is designed to explore the potential and current limitations of large language models as artificial intelligence-based clinical decision-support tools in neurorehabilitation.

Popolazione di studio

No human study population is included. The analytical sample consists of five standardized synthetic spinal cord injury scenarios and the responses generated for these scenarios by ChatGPT-4o, Claude, Grok 3, and Gemini 2.5 Pro. Each model is evaluated under the same standardized prompting conditions. Model outputs are anonymized and independently rated by expert evaluators for clinical accuracy, technical feasibility, safety awareness, consistency with clinical guidance, and response completeness.

Descrizione

Inclusion Criteria:

  • Responses generated for one of the five predefined standardized synthetic spinal cord injury scenarios.
  • Responses generated using the identical standardized prompt specified in the study protocol.
  • Responses generated by one of the four prespecified large language models.
  • Complete responses available for expert evaluation.

Exclusion Criteria:

  • Responses generated using prompts that differ from the standardized study prompt.
  • Incomplete, interrupted, or technically corrupted model outputs.
  • Duplicate responses or outputs not corresponding to a predefined synthetic scenario.
  • Any response generated using real patient-identifiable or personal health information.
