This study aimed to assess the following in individuals after stroke: (1) relationship between upper limb (UL) use by direct observation at home with use perceived and measured by accelerometers; (2) complementarity of these three measurements; and (3) relationship between UL bilateral capacity and bilateral use.
Thirty-one individuals with chronic hemiparesis participated in this cross-sectional study. UL use was assessed using a behavioral map (BM), the Motor Activity Log-Amount of Use (MAL-AOU), and accelerometers, while UL capacity was assessed using the (TEMPA).
The BM was strongly correlated with perceived use (MAL-AOU, ρ = 0.76) and accelerometer (ρ = 0.70). Bilateral UL use (BM) was moderately (ρ = 0.65) correlated with bilateral MAL-AOU and bilateral use by accelerometers (ρ = 0.62). The BM aided our understanding of how the paretic UL was used. The correlation between bilateral capacity (TEMPA bilateral) and bilateral use (BM) was significant (ρ = 0.49), while that with bilateral MAL-AOU and accelerometer were ρ = 0.68 and ρ = 0.50, respectively.
A BM is a valid way to quantify UL use and can complement information assessed regarding perceived use and by accelerometers.Implications for rehabilitationBehavioral maps may be valuable to complement information assessed by perceived UL use and accelerometers.Quantifying bilateral capacity will reflect in a better understanding of actual paretic UL use after stroke.Accelerometers can underestimate the amount of paretic UL use in asymmetrical bilateral tasks.
本研究旨在评估脑卒中患者的以下情况：（1）在家中通过直接观察上肢（UL）使用与通过加速度计感知和测量的使用之间的关系；（2）这三种测量方法的互补性；（3）UL 双侧能力与双侧使用之间的关系。
31 名慢性偏瘫患者参与了这项横断面研究。使用行为图（BM）、运动活动日志-使用量（MAL-AOU）和加速度计评估 UL 使用情况，而 UL 能力则使用 TEMPA 评估。
BM 与感知使用（MAL-AOU，ρ=0.76）和加速度计（ρ=0.70）高度相关。双侧 UL 使用（BM）与双侧 MAL-AOU 和双侧加速度计使用呈中度相关（ρ=0.65）。BM 有助于我们理解非瘫痪 UL 的使用方式。双侧能力（TEMPA 双侧）与双侧使用（BM）之间的相关性具有统计学意义（ρ=0.49），而与双侧 MAL-AOU 和加速度计的相关性分别为 ρ=0.68 和 ρ=0.50。
BM 是一种量化 UL 使用的有效方法，可以补充感知使用和加速度计评估的信息。
行为图可能对补充通过感知 UL 使用和加速度计评估的信息有价值。量化双侧能力将更好地反映脑卒中后实际瘫痪 UL 使用情况。加速度计可能会低估不对称双侧任务中瘫痪 UL 的使用量。
