| Summary: | Accurate monitoring of physical activity (PA) and sedentary behaviour (SB) is crucial for tailoring interventions aimed at improving movement behaviour. This study evaluated the validity of the pocket-worn RISE device for measuring movement behaviour in community-dwelling patients with stroke. Criterion validity was assessed in a laboratory setting using video recordings. Construct validity was assessed in a free-living setting using the thigh-affixed ActivPAL. In the laboratory setting (25 participants, 66 ± 11.8 years), the RISE device showed good criterion validity for SB and PA. In the free-living setting (19 participants, 73 ± 10.2 years), the RISE device showed good construct validity for SB and PA, though further improvements could enhance the accuracy of individual-level measurements of moderate to vigorous physical activity (MVPA) and prolonged sedentary bouts. The mean absolute percentage error and mean percentage error were below the predefined 20% threshold for SB and PA. Intraclass correlation coefficients (ICCs) for SB and PA showed good reliability, but ICC ranges for prolonged sedentary bouts and MVPA were too broad to draw firm conclusions. These findings indicate the RISE device is well-suited for measuring SB and PA in free-living conditions. With real-time feedback, app compatibility, and pocket-wear convenience, the RISE device shows potential for behavioural interventions targeting movement behaviour in stroke and other chronic conditions. |
