摘要

在过去12个月内报告跌倒的成年人(N = 54, 80.78±6.08岁)参加了为期12周的内焦或外焦(EF)指导的摆动板训练计划。训练结束后进行语言操作检查,作为使用的注意力焦点的自我报告。随后计算参与者使用EF (EFSR)报告的会话百分比。在第0、6、12、13、16和20周的摇晃板任务中,评估35秒的前后(MVELOAP和MPFAP)和中外侧(MVELOML和MPFML)方向的平均速度和平均功率频率,后3周作为保持测试。分段线性生长模型估计了在干预和保留期间,治疗对MVELOAP和ML、MPFAP和ML个体生长轨迹的影响。无论条件如何,MVELOML均显著降低(π =−)。0019, p = .005), MPFML增高(π = .005)。025, p < .02)。在包括相互作用项的分析中,EF组中报告较高EFSR的参与者在干预期间MPFAP的进展更优越(π =。0013, p = .025)。语言操作检查表明EF在促进姿势控制性能和自动化方面具有优势。

Postural Control in Older Adults During and Following a 12-Week Balance Training Intervention With Attentional Focus Instructions
Adults (N = 54, 80.78 ± 6.08 years) who reported falling during the previous 12 months participated in a 12-week wobble board training program with internal focus or external focus (EF) instructions. Verbal manipulation checks were performed after training sessions as a self-report of the attentional foci used. The percentage of sessions in which participants reported using an EF (EFSR) was subsequently calculated. Mean velocity and mean power frequency in the anterior–posterior (MVELOAP and MPFAP) and medial–lateral (MVELOML and MPFML) direction were assessed during a 35-s wobble board task at Weeks 0, 6, 12, 13, 16, and 20, with the latter three as retention tests. Piecewise linear growth models estimated treatment effects on individual growth trajectories of MVELOAP and ML and MPFAP and ML during intervention and retention periods. Regardless of condition, MVELOML significantly decreased (π = −.0019, p = .005) and MPFML increased (π = .025, p < .02) during the intervention period. In analyses including interaction terms, participants in the EF group who reported greater EFSR had superior progression of MPFAP during the intervention (π = .0013, p = .025). Verbal manipulation checks suggest a preference for and advantage of EF for facilitating postural control performance and automaticity.

期刊介绍: The Journal of Motor Learning and Development (JMLD) publishes peer-reviewed research that advances the understanding of movement skill acquisition and expression across the lifespan. JMLD aims to provide a platform for theoretical, translational, applied, and innovative research related to factors that influence the learning or re-learning of skills in individuals with various movement-relevant abilities and disabilities.
