This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a portable robotic ankle device called AMBLE to help stroke survivors recover better walking. About 30% of people who survive a stroke are left with foot drop—difficulty lifting and clearing the foot when walking—which increases fall risk and limits mobility. The robot works by providing just-enough assistance during physical therapy to help your brain relearn how to walk, gradually stepping back so you regain control.
Currently, stroke survivors with foot drop rely on canes, walkers, and ankle braces for safety, but these tools don't fix the underlying problem. This trial exists to see whether the robotic device can actually help your nervous system recover and improve walking function in ways that traditional therapy alone cannot.

You would attend 18 one-hour physical therapy sessions over 9 weeks. Depending on which group you're assigned to, you'll either wear the robotic ankle device while doing walking and mobility exercises, or do the same exercises with just your therapist's help. The therapy is divided into three phases of increasing difficulty based on your progress, and you'll be doing real-world walking tasks—not just treadmill work—so the skills carry over to your daily life.
