Little is known about daily walking distance levels, which accounts for approximately 80% of overall physical activity per day, in adolescents with idiopathic scoliosis (AIS).
The aim of this study was to assess the level of walking distance in AIS treated by bracing or not, comparing this activity with that of a control group. We used an original method based on smartphone pedometers for studying walking distance in everyday life.
Nineteen AIS patients, aged 14.1 (13-17) years, and 25 asymptomatic patients, aged 12.9 (12-14) years were included prospectively. The 19 AIS cases comprised 9 untreated individuals and 10 with ongoing night brace treatment. The mean walking distance per day as estimated by the pedometer application on smartphones for 2 months was assessed. Weekly sports activities (hours per week) were also reported.
During the first month, the mean walking distance was 2.58±0.65 km/day for control patients, 2.31±1.38 km/day for untreated AIS, and 3.65±0.72 km/day for AIS patients treated with a night brace. During the second month, the mean walking distance was 2.60±0.73 km/day for control patients, 2.40±1.41 km/day for untreated AIS, and 3.70±0.72 km/day for AIS patients treated with a night brace. Statistical analysis between groups showed a statistically significant difference with a higher level of daily walking distance in adolescents treated with a night brace compared with other groups.
The pedometer on smartphones is a cost-effective and friendly tool to assess adolescents' level of walking distance. Our results indicate no restriction in terms of daily walking distance between adolescents without scoliosis and those with idiopathic scoliosis.

对于特发性脊柱侧凸（AIS）患者，每天的步行距离约占每天总体力活动的 80%，但目前对于该人群的每日步行距离水平知之甚少。
本研究旨在通过使用智能手机计步器评估支具治疗或未治疗 AIS 患者的步行距离水平，并将其与对照组相比较。我们采用了一种基于智能手机计步器的原始方法来研究日常生活中的步行距离。
前瞻性纳入 19 例 AIS 患者（年龄 14.1 岁[13-17 岁]）和 25 例无症状患者（年龄 12.9 岁[12-14 岁]）。使用智能手机上的计步器应用程序评估 2 个月的每日平均步行距离。还记录每周体育活动（小时/周）。
在第一个月，对照组患者的平均每日步行距离为 2.58±0.65km/d，未治疗的 AIS 患者为 2.31±1.38km/d，夜间支具治疗的 AIS 患者为 3.65±0.72km/d。在第二个月，对照组患者的平均每日步行距离为 2.60±0.73km/d，未治疗的 AIS 患者为 2.40±1.41km/d，夜间支具治疗的 AIS 患者为 3.70±0.72km/d。组间统计学分析显示，夜间支具治疗的 AIS 患者的每日步行距离明显更高，与其他组存在统计学差异。
智能手机计步器是一种经济实惠且易于使用的工具，可用于评估青少年的步行距离水平。我们的研究结果表明，无脊柱侧凸青少年与特发性脊柱侧凸青少年的日常步行距离无明显差异。
