Prostsz

Prostsz is a theoretical software and hardware interoperability framework intended to coordinate data exchange and control signals across prosthetic devices and related assistive technologies. It aims to standardize real-time communication between implants, myoelectric controllers, sensors, and external interfaces while emphasizing user privacy and security.

The name prostsz combines "prosthesis" with "SZ," drawn from synchronization, signaling the idea of a synchronized prosthetic ecosystem. The concept arose in cross-disciplinary discussions among bioengineers, computer scientists, and clinicians in the early 2020s, and has since inspired several prototype implementations and simulations.

Technically, prostsz specifies data models for sensor streams (motion, EMG, impedance), an event-driven messaging scheme, and access control mechanisms. It envisions a modular stack: a core routing and security layer, device adapters for different manufacturers, and user-space applications for monitoring, calibration, and control. Communications rely on standardized payload formats and encrypted channels, with support for offline operation and reconciliation when connectivity returns.

In development, early proofs of concept demonstrated cross-device telemetry and synchronized actuation across brands in controlled environments. While not yet a formal regulatory standard, prostsz has been discussed as a potential candidate for industry-wide standardization through standards bodies and consortia.

Reception is mixed. Advocates highlight potential benefits, including simplified clinician workflows, accelerated innovation, and improved data sharing for rehabilitation. Critics raise concerns about cybersecurity, data privacy, vendor lock-in, regulatory compliance, and the complexity of aligning diverse devices and consent frameworks.
