“…13,14 This study is an additional analysis of a cohort of subjects whose data were used in previous publications. 14,15 We aimed to investigate the changes in UL capacity and performance from 3 to 6 months post-stroke. Furthermore, we wanted to examine the association between patients' UL capacity, assessed with ARAT, and actual UL performance in patients' everyday lives, measured with accelerometers at 3 and 6 months after stroke.…”

“…In this study, we highlighted that the measure of choice depends on the aspect of UL activity of interest. If a general overview of the duration of UL activity is wanted, activity ratio is a good choice, as it has strong psychometric properties [ 5 , 11 ], has established norm values [ 9 , 12 ], and is easy to understand. If, on the other hand, we want a better view of how both limbs are used together in terms of contribution to and intensity of UL activity, magnitude ratio and bilateral magnitude may add value.…”

“…This was an exploratory study of cross-sectorial data obtained from two cohort studies, performed in two different countries. We combined data collected at either 6 months post stroke in Denmark [ 12 ] or later than 6 months post stroke in Belgium [ 18 ]. The inclusion criteria in both studies were persons with first or recurrent stroke, more than 18 years old, and with cognitive ability to comply with the examinations.…”

“…The activity ratio is reliable and valid, and norm values for different age groups have been established [ 5 , 11 ]. These norm values allow analyzing the divergence from normal use in populations with stroke [ 9 , 12 ]. Although the activity ratio informs about the relative contribution from each UL to the activity, this information is incomplete.…”

We examined factors associated with different aspects of upper-limb (UL) activity in chronic stroke to better understand and improve UL activity in daily life. Three different aspects of UL activity were represented by four sensor measures: (1) contribution to activity according to activity ratio and magnitude ratio, (2) intensity of activity according to bilateral magnitude, and (3) variability of activity according to variation ratio. We combined data from a Belgian and Danish patient cohort (n = 126) and developed four models to determine associated factors for each sensor measure. Results from standard multiple regression show that motor impairment (Fugl–Meyer assessment) accounted for the largest part of the explained variance in all sensor measures (18–61%), with less motor impairment resulting in higher UL activity values (p < 0.001). Higher activity ratio, magnitude ratio, and variation ratio were further explained by having the dominant hand affected (p < 0.007). Bilateral magnitude had the lowest explained variance (adjusted R2 = 0.376), and higher values were further associated with being young and female. As motor impairment and biological aspects accounted for only one- to two-thirds of the variance in UL activity, rehabilitation including behavioral strategies might be important to increase the different aspects of UL activity.
