324: When Robots Amplify Mistakes To Drive Recovery: Error Augmentation In Neuro Rehab With BioXtreme

In this episode, host Erin Gallardo, PT, DPT, NCS interviews BioXtreme CEO Eyal Samuel Shachar and researcher Dr. James Patton, PhD about BioXtreme's robotics-based neurorehabilitation devices, with a focus on their Plaxtream hand system. Inspired by founder Nini Bluman's experience helping his father recover hand function after a stroke, Plaxtream combines robotic hardware, engaging game-based activities, and an AI-driven, adaptive error augmentation approach to improve grasp, release, pronation, and supination. Dr. Patton explains how error augmentation—strategically amplifying movement errors within an optimal "sweet spot"—can accelerate neuroplasticity and learning, and he shares clinical findings showing functional gains using standardized measures like Fugl-Meyer and Wolf Motor Function tests. The guests discuss how the device personalizes training based on each person's range of motion and strength, supports patients from early to chronic stages (with both active and assistive modes), and is designed for in-clinic use. They also highlight BioXtreme's rapid, feedback-driven development process, the importance of close collaboration between engineers and clinicians, and new opportunities for therapists to get involved in research, education, and U.S. market expansion efforts.
