To investigate the effect of a 6-week stroboscopic balance training program on cortical activities in athletes with chronic ankle instability.
Randomized controlled trial.
Single-center.
Thirty-nine participants were assigned to the strobe group (SG, n = 13), non-strobe group (NSG, n = 13), and control group (CG, n = 13).
Cortical activity and balance velocity were evaluated while the athletes were on the HUBER balance device. Electroencephalographic measurements of cortical activity were made at the transition from bipedal stance to single-leg stance.
The SG showed significant increases in Cz theta and alpha values and COP-v (center of pressure velocity) between pretest and posttest (p < 0.001, p = 0.003, p < 0.001). Posttest Cz theta was significantly higher in the SG compared to the CG (p = 0.009) and posttest Cz alpha was significantly higher in the SG compared to the NSG (p = 0.039) and CG (p = 0.001). Posttest COP-v was significantly higher in the SG than in the CG (p = 0.031) and NSG (p = 0.03).
Stroboscopic training may be clinically beneficial to improve balance parameters in athletes with CAI, and may have utility in sport-specific activity phases of rehabilitation to reduce visual input and increase motor control.
研究 6 周频闪平衡训练计划对慢性踝关节不稳运动员皮质活动的影响。
随机对照试验。
单中心。
39 名参与者被分配到频闪组（SG，n=13）、非频闪组（NSG，n=13）和对照组（CG，n=13）。
运动员在 HUBER 平衡装置上时，评估皮质活动和平衡速度。在从双足支撑到单足支撑的过渡期间，进行皮质活动的脑电图测量。
SG 在 Cz theta 和 alpha 值以及 COP-v（压力中心速度）方面，与预测试相比，后测试时均有显著增加（p<0.001，p=0.003，p<0.001）。SG 的后测试 Cz theta 值明显高于 CG（p=0.009），SG 的后测试 Cz alpha 值明显高于 NSG（p=0.039）和 CG（p=0.001）。SG 的后测试 COP-v 明显高于 CG（p=0.031）和 NSG（p=0.03）。
频闪训练可能对改善 CAI 运动员的平衡参数具有临床益处，并可能在康复的特定运动活动阶段有用，以减少视觉输入并增加运动控制。
