Fitness trackers vs. Doctor's eye: which better gauges cancer Patients' mobility?

This study tested whether consumer movement trackers could provide a more precise measure of cancer patients' physical abilities than the standard ECOG score, which relies on a doctor's observation. Researchers enrolled 41 cancer patients and used a Kinect device to record their movements during simple tasks like standing up and walking. The goal was to see if these objective measurements could better predict how well patients can function, which helps guide treatment decisions.
