To compare the effects of attentional focus to augment balance outcomes in individuals with Parkinson's disease.
Randomised controlled clinical trial.
University gait and balance research laboratory.
Forty-nine individuals with idiopathic Parkinson's disease.
Participants were randomly assigned into one of four groups (three balance intervention groups and one control). The three intervention groups all received the same 4-week balance training program augmented with either external, internal, or no focus instructions. The control group did not receive any balance training.
Outcomes were measured at baseline, post intervention, 2-weeks post intervention, and 8-weeks post intervention and included: Sensory Organization Test, Berg Balance Scale, Self-Selected Gait Velocity, Dynamic Gait Index, Activities-Specific Balance Confidence Scale, and obstacle course completion time.
There were no differences among the groups in trajectory over the course of the trial for all outcomes (ps ⩾ .135). All groups improved from baseline to post intervention and from baseline to 2-weeks post intervention for all outcomes (ps ⩽ .003), except Self-Selected Gait Velocity, which did not change over the course of the trial (P = .121).
Attentional focus instructions to augment a 4-week balance training program did not result in any change over and above a control group in measures of gait and balance in individuals with Parkinson's disease. Additionally, while all four groups improved, there was no difference among the groups, including the control, suggesting that the 4-week balance training program in this trial was not effective.
比较注意力焦点对改善帕金森病患者平衡能力的影响。
随机对照临床试验。
大学步态与平衡研究实验室。
49名特发性帕金森病患者。
参与者被随机分为四组（三个平衡干预组和一个对照组）。三个干预组均接受相同的为期4周的平衡训练计划，并分别附加外部、内部或无焦点指导。对照组未接受任何平衡训练。
在基线、干预后、干预后2周和干预后8周测量结果，包括：感觉统合测试、伯格平衡量表、自选步态速度、动态步态指数、特定活动平衡信心量表和障碍课程完成时间。
在试验过程中，所有结果的组间轨迹均无差异（p值≥0.135）。除自选步态速度在试验过程中未改变（P = 0.121）外，所有组在所有结果上从基线到干预后以及从基线到干预后2周均有改善（p值≤0.003）。
在为期4周的平衡训练计划中附加注意力焦点指导，在帕金森病患者的步态和平衡测量方面，与对照组相比没有产生任何变化。此外，虽然所有四组均有改善，但包括对照组在内的各组之间没有差异，这表明本试验中的为期4周的平衡训练计划无效。
