To examine how postural control changes following pediatric mild traumatic brain injury.
Urban pediatric emergency department.
Children 11 to 16 years old who presented within 6 hours of sustaining mild traumatic brain injury.
Prospective observational cohort followed for 1 month.
Total center of pressure path velocity and path velocity within distinct frequency bands, ranging from moderate to ultralow, were recorded by the Nintendo Wii Balance Board during a 2-legged stance. Measurements were recorded in 2 separate tests with eyes open and closed. The scores of the 2 tests were compared, and a Romberg quotient was computed.
Eleven children were followed for 1 month postinjury. The ultralow frequency, which reflects slow postural movements associated with exploring stability boundaries, was lower (p = .02) during the eyes closed stance acutely following injury. The Romberg quotient for this frequency was also significantly lower acutely following injury (p = .007) than at 1 month.
Following mild traumatic brain injury, children acutely demonstrate significantly more rigid sway patterns with eyes closed than with eyes open, which were highlighted by the Romberg quotient. The Romberg quotient could allow for accurate identification and tracking of postural instability without requiring knowledge of preinjury balance ability.
研究小儿轻度创伤性脑损伤后姿势控制如何变化。
城市儿科急诊科。
在轻度创伤性脑损伤后6小时内就诊的11至16岁儿童。
前瞻性观察队列，随访1个月。
在双脚站立期间，通过任天堂Wii平衡板记录总压力中心路径速度以及从中度到超低不同频段内的路径速度。测量在睁眼和闭眼的2个单独测试中进行。比较2个测试的分数，并计算罗姆伯格商数。
11名儿童在受伤后随访1个月。反映与探索稳定性边界相关的缓慢姿势运动的超低频，在受伤后急性期闭眼站立时较低（p = 0.02）。该频率的罗姆伯格商数在受伤后急性期也显著低于1个月时（p = 0.007）。
轻度创伤性脑损伤后，儿童在闭眼时比睁眼时急性表现出明显更僵硬的摇摆模式，这在罗姆伯格商数中得到突出体现。罗姆伯格商数可以在无需了解伤前平衡能力的情况下，准确识别和跟踪姿势不稳定情况。
