Abstract

Aim: The aim of this study was to evaluate the construct validity of the Both Hands Assessment (BoHA) using activity of the upper limbs as detected by accelerometry in children with bilateral cerebral palsy (CP).

Methods: Observational study of children with CP (n = 44, n = 27 boys, aged 9.1 ± 1.6 years; Manual Ability Classification Scale I: n = 15, II: n = 22, III: n = 7) completing a BoHA assessment while wearing a triaxial accelerometer on each wrist. BoHA Each-Hand sub-scores, BoHA percentage difference between hands, BoHA Units, mean activity for each hand, mean activity asymmetry index and total mean activity were calculated. Linear regressions were used to analyze associations between measures.

Results: There were significant, positive associations between BoHA Units and total mean activity (B = 0.86, 95%CI: 0.32, 1.40), BoHA Percentage difference between hands and mean activity asymmetry index (B = 0.95, 95%CI: 0.75,1.15), and BoHA Each-Hand sub-score and mean activity for the non-dominant hand (B = 1.71, 95%CI: 1.16, 2.28), but not the dominant hand (B = 0.50, 95%CI: -0.45, 1.45).

Conclusions: This study provides further evidence for the construct validity of the BoHA as a measure of upper limb performance. Wearable wrist sensors such as accelerometers capture and quantify gross upper limb movement in children with CP but cannot measure fine finger movements captured by the BoHA.

使用腕戴式加速度计进行双手评估的结构有效性。

目的：本研究旨在评估双手评估（BoHA）在双侧脑瘫（CP）儿童中的结构有效性 = 44，n = 27名男孩，年龄9.1岁 ± 1.6 年；手动能力分类量表I:n = 15，II:n = 22，III:n = 7）在每个手腕上佩戴三轴加速度计的同时完成BoHA评估。计算每只手的BoHA子得分、手之间的BoHA百分比差异、BoHA单位、每只手平均活动、平均活动不对称指数和总平均活动。线性回归用于分析度量之间的相关性。结果：BoHA单位与总平均活性呈正相关（B = 0.86，95%CI:0.32，1.40），手与平均活动不对称指数之间的BoHA百分比差异（B = 0.95，95%CI:0.75,1.15），以及BoHA每只手的子得分和非优势手的平均活动（B = 1.71，95%CI:1.16，2.28），但不是优势手（B = 0.50，95%可信区间：-0.45，1.45）。结论：本研究为BoHA作为上肢表现指标的结构有效性提供了进一步的证据。可佩戴的手腕传感器，如加速度计，可以捕捉和量化CP儿童的上肢粗运动，但不能测量BoHA捕捉到的手指精细运动。临床试验注册：澳大利亚-新西兰临床试验注册中心（ACTRN12616001488493和ACTRN12618000164291）。
