背景:频闪视觉训练可以迫使感觉重新加权,通过增强对于本体感觉信息的敏感性而使其重新恢复原有权重,这可能是改善本体感觉的有效方法。目的:确定低频、高频和正常视觉条件下的平衡训练对慢性踝关节不稳患者踝关节本体感觉的影响。方法:在西南医科大学学生中招募36例慢性踝关节不稳患者,随机分为低频视觉训练组(n=12)、高频视觉训练组(n=12)和正常视觉训练组(n=12),均进行渐进跳跃稳定平衡训练,其中低频视觉训练组、高频视觉训练组在训练过程中佩戴频闪眼镜,频闪频率分别为1.75,5 Hz,每周训练3次,连续训练4周。训练前及训练完成后1周内,评估所有受试者的踝关节本体感觉、动态姿势稳定性和踝关节稳定性自我评价。结果与结论:①踝关节本体感觉具有显著的时间主效应(P<0.05);与训练前相比,低频视觉训练组和高频视觉训练组受试者训练4周后的踝关节本体感觉有明显改善(P<0.05);训练4周后,低频视觉训练组受试者的踝关节本体感觉较正常视觉训练组有明显改善(P<0.05);②踝关节稳定性自我评价具有显著的时间主效应、组别×时间因素主效应(P<0.05);与训练前比较,3组训练4周后的踝关节稳定性自我评价均提高(P<0.05);训练4周后,高频视觉训练组受试者的踝关节稳定性自我评价高于正常视觉训练组(P<0.05);③与训练前相比,低频视觉训练组、高频视觉训练组受试者训练4周后的前向动态姿势稳定性、后内侧动态姿势稳定性、后外侧动态姿势稳定性均有明显改善(P<0.05),正常视觉训练组受试者训练4周后的前向动态姿势稳定性、后外侧动态姿势稳定性均有明显改善(P≤0.05);④结果表明,无论频率如何,在频闪视觉条件下进行平衡训练均可以改善慢性踝关节不稳患者的本体感觉、踝关节稳定性自我评价及动态姿势稳定性。
BACKGROUND:Stroboscopic visual training can force sensory reweighting to restore the original weights by increasing sensitivity to proprioceptive information,which may be an effective method to improve proprioception.OBJECTIVE:To determine the effects of balance training in three conditions,low frequency,high frequency and normal vision,on ankle proprioception in patients with chronic ankle instability.METHODS:Thirty-six patients with chronic ankle instability recruited from the students of Southwest Medical University were randomly assigned to a lowfrequency vision training group,a high-frequency vision training group,and a normal vision training group,with 12 subjects in each group.Subjects in the three groups underwent progressive hop stabilization and balance training,in which the low-frequency vision training group and the high-frequency vision training group wore stroboscopic spectacles during the training,with a stroboscopic frequency of 1.75 and 5 Hz,respectively.The training in each group was performed three times a week for 4 consecutive weeks.Assessments,including ankle proprioception,ankle stability self-assessment and dynamic postural stability,were performed before training and within 1 week after the completion of training.RESULTS AND CONCLUSION:There was a significant main effect of time factor in ankle proprioception(P<0.05).Compared with the pre-training period,subjects in the low-frequency vision training group and the high-frequency vision training group showed significant improvement in ankle proprioception after 4 weeks of training(P<0.05);and subjects in the low-frequency vision training group showed a significant improvement in ankle proprioception compared with that of the normal vision training group after 4 weeks of training(P<0.05).There were significant main effects of time factor and group×time interaction in ankle proprioception(P<0.05).Compared with the pre-training period,the ankle stability self-assessment in all three groups was improved after 4 weeks of training(P<0.05).And the ankle stability self-assessment in high-frequency visual training group was higher than that in normal vision training group after 4 weeks of training(P<0.05).Compared with the pre-training period,subjects in the low-frequency vision training group and the high-frequency vision training group showed significant improvements in forward dynamic postural stability,posteromedial dynamic postural stability,and posterolateral dynamic postural stability after 4 weeks of training(P<0.05),while in the normal vision training group,forward dynamic postural stability and posterolateral dynamic postural stability were significantly improved after 4 weeks of training(P≤0.05).To conclude,balance training under stroboscopic visual conditioning improves proprioception,ankle stability self-assessment,and dynamic postural stability in patients with chronic ankle instability regardless of frequency.
