There is physiological and biomechanical evidence suggesting a possible advantage of using poles in walking training programs. The purpose of this proof-of-concept study was to test the hypothesis that untrained elderly training Nordic walking for eight weeks will show higher improvements on the functional mobility, quality of life and postural balance than that training without poles; more likely to occur in self-selected walking speed (primary outcome), and the locomotor rehabilitation index than the quality of life, the static balance and the dynamic stability. It was a two-arm randomized sample- and load-controlled study.
Thirty-three untrained older people were randomly assigned into Nordic walking (n = 16, age: 64.6±4.1 years old) and free walking (n = 17, age: 68.6±3.9 years old) training groups.
Improvements in the self-selected walking speed (primary outcome, p = 0.011, ES = 0.42 95%CI -0.31 to 1.16), locomotor rehabilitation index (p = 0.013, ES = 0.36; (95%CI -0.39 to 1.10), quality of life (p<0.05), static balance (p<0.05) and dynamic variability (p<0.05) were found in both groups.
The hypothesis was not supported, our findings indicated that after 8 weeks, the Nordic walking training did not result in greater improvements than free walking training for the primary outcome (self-selected walking speed) and most of the secondary outcomes (including locomotor rehabilitation index, static balance, dynamic stability, and psychological and social participation domains of quality of life).

有生理和生物力学证据表明，在步行训练计划中使用手杖可能具有优势。本概念验证研究的目的是检验以下假设：未经训练的老年人接受 8 周的北欧式行走训练，在功能性移动性、生活质量和姿势平衡方面的改善程度高于不使用手杖的训练；更有可能在自我选择的步行速度（主要结果）和运动康复指数方面得到改善，而不是在生活质量、静态平衡和动态稳定性方面。这是一项双臂随机样本和负荷对照研究。
33 名未经训练的老年人被随机分为北欧式行走组（n = 16，年龄：64.6±4.1 岁）和自由行走组（n = 17，年龄：68.6±3.9 岁）。
自我选择的步行速度（主要结果，p = 0.011，ES = 0.42 95%CI -0.31 至 1.16）、运动康复指数（p = 0.013，ES = 0.36；95%CI -0.39 至 1.10）、生活质量（p<0.05）、静态平衡（p<0.05）和动态可变性（p<0.05）在两组中均有改善。
假设未得到支持，我们的研究结果表明，在 8 周后，北欧式行走训练并没有比自由行走训练在主要结果（自我选择的步行速度）和大多数次要结果（包括运动康复指数、静态平衡、动态稳定性以及生活质量的心理和社会参与领域）上产生更大的改善。
