To examine the effect of attentional focus instructions and dynamic balance training on ankle sprain recovery.
Randomized controlled trial.
Outpatient physical therapy department.
Forty volunteers (age range, 19-33y) referred to treatment within 4 months after sustaining a grade 1 or 2 ankle sprain with no concurrent impairments. Participants were randomly allocated to 1 of 2 groups differing in training instructions.
Postural control training consisted of ten 20-second trials, performed on 3 consecutive days, at 2 stability levels of the Biodex Stability System (BSS). Training instructions directed the participants to either an internal or an external focus of attention. Assessments were conducted on the BSS pre- and post-training, and 48 hours after the last session (retention test).
Overall stability as indicated by variance in platform displacement in all directions; anteroposterior (AP) variance of platform displacement; and mediolateral variance of platform displacement.
Increases in overall and AP stability were observed immediately following training in both groups and were maintained at the retention test. Interaction effect indicates greater improvement in the external-focus group.
Our results suggest that external focus of attention is advantageous for the learning of a postural control task following an ankle injury.
探讨注意力焦点指导和动态平衡训练对踝关节扭伤恢复的影响。
随机对照试验。
门诊物理治疗科。
40名志愿者（年龄范围19 - 33岁），在发生1级或2级踝关节扭伤且无并发损伤后4个月内前来接受治疗。参与者被随机分配到两组中的一组，两组训练指导不同。
姿势控制训练包括在Biodex稳定系统（BSS）的2个稳定水平上连续3天进行10次每次20秒的试验。训练指导引导参与者将注意力集中在内部或外部。在训练前和训练后以及最后一次训练后48小时（留存测试）在BSS上进行评估。
平台在各个方向位移的方差表示的整体稳定性；平台位移的前后（AP）方差；以及平台位移的内外侧方差。
两组在训练后立即观察到整体稳定性和AP稳定性增加，并在留存测试中保持。交互作用表明外部焦点组有更大的改善。
我们的结果表明，注意力的外部焦点有利于踝关节损伤后姿势控制任务的学习。
