Infants at high-risk of unilateral Cerebral Palsy (UCP) may have asymmetry in upper extremity movement and function, which should be identified as soon as possible for management.
To explore the feasibility of using two AX3 Axivity monitors in wrist-worn bracelets to quantify movements, and to identify whether accelerometry parameters are consistent with hand function.
6 infants at high risk of UCP (aged 3 to -12 months) were included in a Single-Case Experimental Design to explore the impact of an 8-week bimanual stimulation home program.
Each week of the baseline (randomized duration 4-7 weeks) and 8-week program, the Hand Assessment for Infants (HAI) was performed and accelerometry parameters were collected during HAI and also during spontaneous activity, several times a week.
Actimetry was analyzed during HAI and 238 spontaneous activity sessions (mean 42 ± 21 min). Actimetry ratios distribution and evolution show a high variability, especially for spontaneous activity. No strong correlation was found between HAI scores and accelerometry parameters, either collected during HAI, or during spontaneous activity times.
Despite its feasibility, using accelerometry bracelets looks unreliable for detecting and monitoring hand function in infants under one year.
患有单侧脑瘫（UCP）高风险的婴儿上肢运动和功能可能存在不对称，应尽快发现并进行管理。
探索使用两个 AX3 Axivity 腕带监测器对手腕运动进行量化的可行性，并确定加速度计参数是否与手功能一致。
纳入 6 名患有 UCP 高风险的婴儿（年龄 3 至-12 个月），采用单病例实验设计，探索 8 周双上肢刺激家庭计划的影响。
在基线（随机持续时间 4-7 周）和 8 周计划的每一周，均进行婴儿手评估（HAI），并在 HAI 期间以及每周几次的自发性活动期间收集加速度计参数。
尽管可行，但使用加速度计腕带看起来不可靠，无法检测和监测一岁以下婴儿的手功能。
