Slackline-training has been shown to improve mainly task-specific balancing skills. Non-task specific effects were assessed for tandem stance and preferred one-leg stance on stable and perturbed force platforms with open eyes. It is unclear whether transfer effects exist for other balancing conditions and which component of the balancing ability is affected. Also, it is not known whether slackline-training can improve non-visual-dependent spatial orientation abilities, a function mainly supported by the hippocampus. To assess the effect of one-month of slackline-training on different components of balancing ability and its transfer effects on non-visual-dependent spatial orientation abilities. Fifty subjects aged 18-30 were randomly assigned to the training group (T) ( = 25, 23.2 ± 2.5 years; 12 females) and the control group (C) ( = 25, 24.4 ± 2.8 years; 11 females). Professional instructors taught the intervention group to slackline over four consecutive weeks with three 60-min-trainings in each week. Data acquisition was performed (within 2 days) by blinded investigators at the baseline and after the training. Main outcomes Improvement in the score of a 30-item clinical balance test (CBT) developed at our institute (max. score = 90 points) and in the average error distance (in centimeters) in an orientation test (OT), a triangle completion task with walking and wheelchair conditions for 60°, 90°, and 120°. Training group performed significantly better on the closed-eyes conditions of the CBT (1.6 points, 95% CI: 0.6 to 2.6 points vs. 0.1 points, 95% CI: -1 to 1.1 points; = 0.011, [Formula: see text] = 0.128) and in the wheelchair (vestibular) condition of the OT (21 cm, 95% CI: 8-34 cm vs. 1 cm, 95% CI: -14-16 cm; = 0.049, [Formula: see text] = 0.013). Our results indicate that one month of intensive slackline training is a novel approach for enhancing clinically relevant balancing abilities in conditions with closed eyes as well as for improving the vestibular-dependent spatial orientation capability; both of the benefits are likely caused by positive influence of slackline-training on the vestibular system function.
已有研究表明，走扁带训练主要能提高特定任务的平衡技能。本研究在睁眼状态下，于稳定及受干扰的测力平台上，对串联站立和优势单腿站立的非特定任务效应进行了评估。目前尚不清楚其他平衡条件下是否存在迁移效应，以及平衡能力的哪个组成部分会受到影响。此外，也不清楚走扁带训练是否能提高非视觉依赖的空间定向能力，该能力主要由海马体支持。为了评估为期一个月的走扁带训练对平衡能力不同组成部分的影响及其对非视觉依赖空间定向能力的迁移效应。50名年龄在18至30岁之间的受试者被随机分为训练组（T）（n = 25，23.2 ± 2.5岁；12名女性）和对照组（C）（n = 25，24.4 ± 2.8岁；11名女性）。专业教练连续四周对干预组进行走扁带训练，每周进行三次60分钟的训练。由不知情的研究人员在基线期和训练后（2天内）进行数据采集。主要结果：我院制定的30项临床平衡测试（CBT）（最高分 = 90分）得分以及定向测试（OT）中的平均误差距离（厘米）有所改善，OT是一项在行走和轮椅状态下针对60°、90°和120°的三角形完成任务。训练组在CBT的闭眼条件下（1.6分，95%置信区间：0.6至2.6分 vs. 0.1分，95%置信区间：-1至1.1分；p = 0.011，Cohen's d = 0.128）以及OT的轮椅（前庭）条件下（21厘米，95%置信区间：8 - 34厘米 vs. 1厘米，95%置信区间：-14 - 16厘米；p = 0.049，Cohen's d = 0.013）表现明显更好。我们的结果表明，为期一个月的强化走扁带训练是一种新的方法，可增强闭眼条件下与临床相关的平衡能力，并改善前庭依赖的空间定向能力；这两种益处可能是由于走扁带训练对前庭系统功能的积极影响所致。
