Background:

The static sciatic index (SSI) is a standard metric for evaluating functional recovery in rat models of peripheral nerve injury.
Current SSI measurement methods are labor-intensive and difficult to standardize across studies.

Purpose of the Study:

To validate a novel machine learning (ML) approach for automated SSI measurement.
To assess the performance of the ML method across diverse experimental setups.
To evaluate end-user requirements for practical application in nerve repair research.

Main Methods:

A previously developed ML algorithm was employed to automatically calculate the static sciatic index.
The ML method was tested on two distinct datasets derived from different experimental configurations.
Performance was compared against traditional manual SSI measurements.

Main Results:

The ML model generated nerve regeneration profiles consistent with manual measurements.
The automated method demonstrated significantly improved consistency, with a tighter standard deviation (±5-±10) compared to manual methods (±10-±50).

Conclusions:

An affordable, automated tool for functional analysis in nerve repair research has been successfully developed and validated.
The open-source software is readily available to enhance the quantification of peripheral nerve crush injury recovery.
