## The human problem

Spinal injury can interrupt signals between the brain and muscles.

## The prior constraint

Existing stimulation systems offered limited voluntary adaptation.

## AI’s actual role

Decoders converted cortical signals into spinal stimulation commands.

## The documented result

The participant used the digital bridge for voluntary movement during the study.

## Why it may matter

A step toward restoring movement under a person’s own control.

## Limitations

A single-participant study with implanted devices and rehabilitation.

## Unresolved questions

Study safety and benefit across more participants.
