To examine the reliability and validity of a simple device, the Swaymeter, for measuring trunk control in children with CP.
Twenty children with spastic CP participated in this study. Trunk sway was measured while quietly sitting for 30s. Children lean forward or backward as far as possible for measuring dynamic balance range. Test-retest reliability was conducted. The concurrent and construct validity of the Swaymeter was assessed by comparison to the motion capture system and gross motor function measure (GMFM).
The reliability of the Swaymeter was moderate to excellent in measuring trunk sway and dynamic balance range (ICCs = 0.696-0.948). Concurrent validity showed good results (r = 0.818-0.997) and construct validity of dynamic balance in anterior direction showed moderate to high correlation with the GMFM (r = 0.599-0.849).
Assessment of trunk control in a sitting position using the Swaymeter in this study was valid and reliable in children with CP.
研究一种简单的设备——Swaymeter，用于测量脑瘫儿童的躯干控制能力，旨在检验其可靠性和有效性。
本研究纳入了 20 名痉挛型脑瘫儿童。通过让儿童安静地坐 30 秒来测量躯干摆动，然后让儿童尽可能地向前或向后倾斜以测量动态平衡范围。进行了测试-重测信度检验。通过与运动捕捉系统和粗大运动功能测量（GMFM）进行比较，评估了 Swaymeter 的同时效度和结构效度。
Swaymeter 测量躯干摆动和动态平衡范围的可靠性为中等到极好（ICC=0.696-0.948）。同时效度显示出良好的结果（r=0.818-0.997），并且前向动态平衡的结构效度与 GMFM 呈中等到高度相关（r=0.599-0.849）。
本研究中，使用 Swaymeter 评估脑瘫儿童坐姿下的躯干控制能力具有有效性和可靠性。
