Metric

Description

Rationale for selection

Upper limb metrics

 Hourly arm use bar graph

This vertical bar plot indicated the total active time of each arm at each hour (from 8am to 11 pm). A green and a red arrow indicates the hour with the most or the least activity

To illustrate arm use activity throughout the day [12]

 Arm use ratio dial plot

This dial plot displayed the percentage of time in active movement between the right and left arms/hands on a half-circle

To quickly see the symmetry of arm/hand movements [12, 19]

 Total active time bar plot

This vertical bar plot indicated the total active time of each arm over the entire day

To provide an overall measure of the activity of each arm/hand [12, 19]

 Use ratios (horizontal bar plot)

This horizontal bar plot displayed the average arm use ratio for each hour. The vertical dotted lines indicated a potential target for symmetrical use of both arms

To visualize movement symmetry throughout the day

We anticipated that this plot may be harder to understand for stroke survivor [12]

Mobility metrics

 Hourly steps bar plot

This vertical bar plot displayed the total number of steps taken by this participant every hour from 8am to 11 pm. A green and a red arrow indicates the hour with the most or the least steps

To show the frequency at which the steps are accrued throughout the day [2, 20]

 Time spent in stance

This vertical plot displayed the time spent in stance on the right and left legs, averaged over the day

To offer gait quality metric

This may be relevant for clinicians and potentially, stroke survivors [21]

 Daily steps bar plot

This vertical bar plot displayed the total number of steps for each day of the week. A green and a red arrow indicates the day with the most or the least steps

To show the walking volume and offer insights as to whether this outcome is consistent or variable between days [2, 22]

 Stance % this week

This vertical plot displayed the time spent in stance on the right and left legs, averaged over the day

To offer gait quality metric and offer insights as to whether this outcome is consistent or variable between days [21]
