Read the walk at the wrist

1 · Say what the study found

Beginner

What did this study show about the patients' walking?

It changes more when the tumour progresses Step counts are enough to spot progression The wristband can already replace MRI

Of the 26 visits analysed, 11 were progressive. The threshold's sensitivity, the share of progressive visits it flags, is 0.727.

Intermediate

How many progressive visits did the threshold flag?

3 8 11

Expert

Why divide each value by the patient's average at stable visits?

To correct for wristband faults To give more weight to stable visits Because everyone walks in their own way

Expert

Why can the method not yet raise the alarm before the MRI?

The wristband only measures walking once a month Its reference may include later stable visits Its area under the curve is too close to chance
