Mean differences in physical activity and survey measures at baseline and follow-up.
| Sensor Parameter | Mean Difference | 95% CI | p |
|---|---|---|---|
| Walking duration (min.) | 8.08 | −18.45, 34.60 | 0.536 |
| Step count | 823.45 | −753.35, 2400 | 0.292 |
| Average steps per walking bout 1 | 4.61 | −1.42, 10.64 | 0.131 |
| Number of long walking bouts 2 | 5.53 | −15.29, 26.37 | 0.588 |
| Percent walking relative to sedentary behavior 3 | 4.08 | −11.96, 3.82 | 0.297 |

| Sleep onset latency (min) 4 | 10.42 | −4.35, 25.20 | 0.158 |
| Wakefulness after sleep onset (min) 5 | 11.73 | −59.44, 35.98 | 0.617 |
| Sit-to-stand transition (seconds) | 0.02 | −0.37, 0.41 | 0.916 |
| Survey Measure | |||
| World Health Organization Quality of Life OLD (WHOQOL-OLD) | 0.02 | −1.88, 2.28 | 0.845 |
| Multimorbid Treatment Burden Questionnaire (MTBQ) | 0.67 | −3.51, 3.65 | 0.970 |
| Community Integration Questionnaire (CIQ) | 0.73 | 0.98, −1.27 | 0.459 |
| Life space function | −0.07 | −4.61, 4.48 | 0.976 |
All measures are reported for a period of 24 h. Change is the difference between measurement at baseline and follow-up. 1 A walking bout is a continuous period of walking without stopping. 2 A long walking bout is >30 steps. 3 Sedentary behavior includes sitting. 4 Sleep onset latency is the length of time that it takes to accomplish the transition from full wakefulness to sleep. 5 When an individual shows evidence of wakefulness after falling asleep.
