In a crossover design, subjects with unilateral vestibular loss (UVL) practiced tandem gait with eyes closed on two days, two weeks apart, with and without vibrotactile biofeedback (BF) applied to the lateral trunk. Results showed an immediate improvement in postural stability (reduction of lateral center-of-mass displacement, trunk tilt, and medial-lateral step width) that was significantly larger than effects of practice alone. However, BF did not increase the rate of improvement or retention of improved stability during gait.
在交叉设计中,单侧前庭丧失(UVL)的受试者在相隔两周的两天内闭眼练习串联步态,分别在有和没有对侧躯干施加振动触觉生物反馈(BF)的情况下进行。结果显示,姿势稳定性立即得到改善(质心横向位移、躯干倾斜和内外侧步幅减小),且改善程度显著大于单纯练习的效果。然而,生物反馈并未提高步态改善的速度或改善后稳定性的保持率。
