Maintaining an upright posture while talking or texting on the phone is a frequent dual-task demand. Using a within-subjects design, the aim of the present study was to assess the impact of a smartphone conversation or message texting on standing plantar pressure and postural balance performance in healthy young adults. Thirty-five subjects (mean age 21.37 ± 1.11 years) were included in this study. Simultaneous foot plantar pressure and stabilometric analysis were performed using the PoData system, under three conditions: no phone (), talking on a smartphone () and texting and sending a text message via a smartphone (). Stabilometric parameters (center of pressure (CoP) path length, 90% confidence area and maximum CoP speed) were significantly affected by the use of different smartphone functions ( < 0.0001). The CoP path length and maximum CoP speed were significantly higher under the and conditions when compared to the . CoP path length, 90% confidence area and maximum CoP speed were significantly increased in compared to and . Talking on the phone also influenced the weight distribution on the left foot first metatarsal head and heel as compared with message texting. Postural stability in healthy young adults was significantly affected by talking and texting on a smartphone. Talking on the phone proved to be more challenging.
在打电话或发短信时保持直立姿势是一种常见的双重任务需求。本研究采用被试内设计，旨在评估智能手机通话或短信输入对健康年轻成年人站立时足底压力和姿势平衡性能的影响。本研究纳入了 35 名受试者（平均年龄 21.37 ± 1.11 岁）。使用 PoData 系统同时进行足底压力和平衡分析，在三种情况下进行：无手机（）、使用智能手机通话（）和使用智能手机输入并发送短信（）。在使用不同智能手机功能时，平衡参数（压力中心（CoP）轨迹长度、90%置信区和最大 CoP 速度）受到显著影响（<0.0001）。与 相比，在 和 条件下，CoP 轨迹长度和最大 CoP 速度显著更高。与 和 相比，在 条件下，CoP 轨迹长度、90%置信区和最大 CoP 速度显著增加。与发短信相比，打电话时还会影响左足第一跖骨头和脚跟的重量分布。智能手机通话和短信输入会显著影响健康年轻成年人的姿势稳定性。与发短信相比，打电话更具挑战性。
