Background

Using a mobile phone while performing a postural and locomotor tasks is a common, daily situation. Conversing or sending messages (SMS) while walking account for a significant share of accidental injuries. Therefore, understanding the consequences of using a mobile phone on balance and walking is important, all the more so when these postural and locomotor tasks are aggravated by a disease.

Research question

Our objective was to conduct a scoping review on the influence of a dual-task situation – generated by the use of mobile phone – on users' postural and/or locomotor tasks.

Methods

The literature search was conducted in English on PubMed/Medline and CINHAL databases, using keywords associated with postural and locomotor tasks and with the use of mobile phone. Study location, population, number of subjects, experimental design, types of phone use, evaluated postural-locomotor tasks and expected effects were then analyzed.

Results and significance

46 studies were included in this work, 24 of which came from North America. All studies compared postural and locomotor tasks with and without the use of a smartphone. Ten studies also compared at least 2 groups with different characteristics. Only 4 studies included pathological subjects. Various modalities were tested, and most studies focused on walking. Results show that the use of smartphones slows down movement and induces a systematic imbalance, except when listening to music. The dual task of "using the smartphone during a postural or locomotor tasks" induces systematic disturbances of balance and movement, which must be taken into account in the rehabilitation approach. Future studies will have to extend the knowledge regarding pathological situations.

使用手机对姿势和运动任务的影响：范围回顾

背景

在执行姿势和运动任务时使用手机是一种常见的日常情况。走路时交谈或发送消息（SMS）在意外伤害中占很大比例。因此，了解在平衡和步行状态下使用手机的后果非常重要，当这些姿势和运动任务因疾病而加重时，尤为如此。

研究问题

我们的目标是对使用手机产生的双重任务情况对用户的姿势和/或运动任务的影响进行范围审查。

方法

文献检索是在PubMed / Medline和CINHAL数据库上以英语进行的，使用与姿势和运动任务相关的关键字以及通过移动电话进行的搜索。然后分析研究地点，人口，受试者人数，实验设计，电话使用类型，评估的姿势运动任务和预期效果。

结果与意义

这项工作包括46个研究，其中24个来自北美。所有研究都比较了使用和不使用智能手机的姿势和运动任务。十项研究还比较了至少两个具有不同特征的组。仅4项研究包括病理学主题。测试了各种方式，大多数研究集中在步行上。结果表明，智能手机的使用会减慢运动速度，并导致系统的不平衡，但听音乐时除外。“在姿势或运动任务中使用智能手机”这一双重任务会引起系统的平衡和运动障碍，这在康复方法中必须予以考虑。未来的研究将不得不扩展有关病理情况的知识。
