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 | |
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] |
