Translational neuropathic pain research

Area of Science:

• Neurology
• Pain Research
• Translational Science

Background:

• Traditional neuropathic pain research often translates animal findings to humans, facing extrapolation challenges.
• An inverse translational approach, starting with human clinical data, has emerged as a valuable strategy.
• Assessing sensory phenotypes guides mechanism-based therapeutic development.

Purpose of the Study:

• To review various aspects of translational research in neuropathic pain.
• To highlight the shift towards inverse and multimodal approaches.
• To emphasize the integration of diverse methods for mechanism investigation and therapeutic response prediction.

Main Methods:

• Narrative review of translational research methodologies in neuropathic pain.
• Analysis of traditional (bottom-up) and inverse (top-down) translational strategies.
• Discussion of multimodal approaches integrating patient data and advanced techniques.

Main Results:

• Inverse translational research, exemplified by neurostimulation, has advanced neuropathic pain therapy.
• Phenotype-guided therapeutic strategies offer insights into underlying mechanisms.
• Multimodal approaches represent the leading trend for mechanistic studies and predicting treatment efficacy.

Conclusions:

• Translational research in neuropathic pain is evolving beyond traditional animal-to-human models.
• Inverse and multimodal strategies are crucial for understanding complex pain mechanisms and developing effective treatments.
• Integrating diverse data sources enhances the prediction of therapeutic success in patients with nerve injury.
