Wearable Monitoring
“Healthy” Activity • Sufficient activity level
• Frequent activity
• Good quality of movement
• Safe movement
“Unhealthy” Activity • Falling
– Long-lie after fall
• Increased fall risk:
– stumbling
– Bad balance and coordination
– Fall history
• Less daily activity
• No variation in activity
