AI coaches knee patients: ChatGPT-5, gemini, and DeepSeek put to the test in rehab trial
NCT ID NCT07267962
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding exercise plans created by AI chatbots (ChatGPT-5, Gemini 2.5 Pro, or DeepSeek V3.1) to standard physical therapy helps people with degenerative knee disease feel better and move easier. 84 adults aged 40-65 took part in an 8-week program with supervised sessions twice a week. Researchers measured pain, function, and quality of life to see if the AI-assisted plans outperformed standard therapy alone.
