What considerations are there for data logging in rehabilitation devices?

• A. Time-stamped events, privacy, data minimization, secure storage, access controls, and data useful for V&V and clinical evaluation.
• B. Only the size of the data files.
• C. Only the color of the log files.
• D. Data logging is optional in rehab devices.

Answer: (B)

Data logging in rehabilitation devices should capture meaningful, traceable information that supports safety, validation, and clinical usefulness. The key idea is to record time-stamped events so you can replay sessions, verify how the device behaved, and detect patterns or issues. Privacy and data minimization matter so only what’s necessary is stored, reducing risks to patients. Secure storage and strict access controls protect the data from unauthorized use, while keeping logs available for those who need them for maintenance, verification, and regulatory reviews. Designing logging with verification, validation, and clinical evaluation in mind ensures the data can support safety assessments, device improvements, and real-world outcomes. Focusing only on data file size misses when events occurred, who accessed data, and how the data will be used; file color is irrelevant; and treating logging as optional would undermine accountability and traceability.
