## Stroke patients face therapy shortage
Strokes leave five million people with long-term impairments each year, but a growing shortage of physical therapists makes it hard for them to get the care they need.
## Robot learns from real therapists
Johannes Lachner at Purdue University and Noah Geiger developed a robotic system using generative AI and real-time force feedback to learn from human therapists and provide personalized assistance during rehabilitation exercises.

> not to replace therapists, but to extend their reach
## Clinical trials and future applications
Initial robotic experiments have demonstrated feasibility. The next phase aims to develop therapist-specific models and evaluate them in a long-term clinical study with patients who previously received manual therapy.
## Key takeaway

Researchers at Purdue and MIT developed a robotic therapy system using generative AI to learn from human therapists and assist stroke patients with rehabilitation exercises.
