The purposes of this pilot project were to examine the impact of power mobility training on (1) electroencephalography (EEG) activity in children with severe cerebral palsy (CP) and (2) power mobility skill acquisition. A single-subject A-B-A-B research design with a 5-week duration for each phase (20 wk total) was replicated across three participants with severe CP (Gross Motor Function Classification System Level V). Data related to the target behaviour, as represented by EEG activity, were collected each week. Power mobility skills were assessed using the Canadian Occupational Performance Measure (COPM), the Wheelchair Skills Checklist (WSC), and the Assessment of Learning Powered mobility use (ALP). Weekly power mobility training was provided during the intervention phases. EEG data were analyzed by means of three measurement metrics (power spectral density, mutual information, and transfer entropy). All three participants demonstrated changes in activation in frontoparietal EEG recordings and clinically significant improvements in power mobility skill acquisition as measured by the COPM as well as by the ALP and WSC. Power mobility training appeared to affect both neuroplastic and skill acquisition. Combining the use of EEG with direct therapist-observation measurement tools may provide a more complete understanding of the impact of power mobility training on children with severe CP.
本试点项目的目的是研究动力移动训练对（1）重度脑瘫（CP）儿童脑电图（EEG）活动的影响，以及（2）动力移动技能习得的影响。对三名重度CP患者（粗大运动功能分类系统V级）采用单受试者A-B-A-B研究设计，每个阶段持续5周（共20周）。每周收集与EEG活动所代表的目标行为相关的数据。使用加拿大职业表现测量（COPM）、轮椅技能检查表（WSC）和学习动力移动使用评估（ALP）对动力移动技能进行评估。在干预阶段提供每周一次的动力移动训练。通过三个测量指标（功率谱密度、互信息和转移熵）分析EEG数据。所有三名参与者的额顶叶EEG记录激活均有变化，并且通过COPM以及ALP和WSC测量，动力移动技能习得在临床上有显著改善。动力移动训练似乎对神经可塑性和技能习得都有影响。将EEG的使用与治疗师直接观察测量工具相结合，可能会更全面地了解动力移动训练对重度CP儿童的影响。
