Summary

This study tested a soft robotic sock called VACOM in 19 stroke patients who had trouble moving their ankle. The sock gently moves the ankle to prevent stiffness and improve blood flow, aiming to reduce the risk of blood clots and contractures. The trial is complete, but results are still being analyzed.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Soft robotic sock (VACOM device)
What this could lead to: If it works, this could offer a new way to help stroke patients regain ankle movement and reduce the risk of blood clots without extra medication.
What could go wrong: This was a very small study (19 people) with no phase, so results are preliminary. The device may not work for everyone, and more research is needed.
