What is a key advantage of wearable sensors for rehab assessment?

• A. They require a clinical lab.
• B. They provide continuous monitoring in natural environments.
• C. They replace therapists entirely.
• D. They produce less data than lab systems.

Answer: (B)

Continuous monitoring in real-world environments is the main advantage. Wearable sensors collect data as people go about daily activities, not just during a single clinic visit. This long-term, natural-context data reveals how function and symptoms change over days or weeks, captures variability between moments of use, and shows how rehab effects translate into real-world performance. That richness lets clinicians track progress more accurately, detect early signs of decline, and tailor interventions based on how a person actually works in daily life.

Note that wearables are designed to augment assessment and care, not replace therapists. They also generate substantial datasets to navigate, rather than being limited to a small lab-based collection. And while some devices can be used in lab settings, their real strength lies in providing continuous, in-context information outside the clinic.
