Which of the following statements best describes a benefit of wearable sensors in rehab monitoring?

• A. They are restricted to lab use.
• B. They require video analysis for interpretation.
• C. They are invasive and uncomfortable for most patients.
• D. They can continuously monitor patients in natural environments.

Answer: (D)

Continuous monitoring in natural environments is a major benefit of wearable sensors in rehab monitoring. These devices capture objective data on movement, activity, gait, balance, and physiology while patients go about daily life, not just during a clinic visit. This real-world data adds ecological validity, shows day-to-day fluctuations, and helps track progress over time with potential for timely therapy adjustments. Most wearables are noninvasive and designed for comfort, enabling long-term use and remote monitoring. In contrast, the other statements don’t fit: wearables aren’t limited to labs, they often provide actionable data without video analysis, and they are typically noninvasive rather than uncomfortable.
