适用于脑瘫儿童的站立式乘驾式电动移动设备

实验性的：Intervention Group

Children with cerebral palsy received an individually adapted stand-on ride-on powered mobility device for home and community use over a three-month intervention period. Participants completed biomechanical assessments before and after the intervention.

设备：站立式骑乘式电动移动设备

孩子们将收到改装的玩具车（个性化改装的站立式 PMD），带回家并使用三个月。 PMD 将在他们的房子和家庭熟悉的环境（例如社区、公园、学校）中使用。

Center of Pressure Sway Area, Standing

Center of pressure sway area during quiet standing was quantified as the 95% confidence ellipse area derived from force plate measurements. Larger sway area values indicate greater postural sway and reduced standing balance stability. Reported values represent the absolute measurements obtained during each of the pre-intervention and post-intervention assessments. For participants completing multiple standing trials at an assessment, the participant-level median across trials was used for analysis. The reported values represent the group median of the participant-level medians for the pre-intervention and post-intervention assessments.

Center of Pressure Sway Area, Sit-to-stand

Measure of dynamic balance control during sit-to-stand. Center of pressure sway area during quiet standing was quantified as the 95% confidence ellipse area derived from force plate measurements. Larger ellipse areas indicate greater postural sway. Reported values represent the absolute measurements obtained during each of the pre-intervention and post-intervention assessments. For participants completing multiple standing trials at an assessment, the participant-level median across trials was used for analysis. The reported values represent the group median of the participant-level medians for the pre-intervention and post-intervention assessments.

Trunk-pelvis Coupling

Quantification of timing and magnitude of whole-body motor control coordination during functional tasks (e.g., sit-to-stand, walking turns). Trunk-pelvis coupling was quantified using vector coding analysis to characterize coordination between trunk and pelvis motion during the movement task. Reported values represent the absolute measurements obtained during each of the pre-intervention and post-intervention assessments. For participants completing multiple trials at an assessment, the participant-level median across trials was used for analysis. The reported values represent the group median of the participant-level medians for the pre-intervention and post-intervention assessments.
