What does SaMD stand for, and which example illustrates it in rehabilitation engineering?

• A. Software as a Medical Device; an example is a software app that controls a home rehabilitation robot based on patient performance data.
• B. System as a Mechanical Device
• C. Software as a Managed Device
• D. Standard as a Medical Device

Answer: (A)

Software as a Medical Device means software that itself delivers the medical function, rather than being just a part of a hardware device. In rehabilitation engineering, a software app that analyzes patient performance data and uses it to drive or control a home rehabilitation robot demonstrates this idea: the medical function—assessing and guiding therapy—is carried out by the software, even though it interacts with hardware. The hardware serves as a platform, but the software is the device delivering the therapeutic action. The other terms aren’t standard concepts in this context.
