Smartphone Use and Postural Balance in Healthy Young Adults

Abstract

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 (control), talking on a smartphone (talk) and texting and sending a text message via a smartphone (text). 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 (p < 0.0001). The CoP path length and maximum CoP speed were significantly higher under the talk and text conditions when compared to the control. CoP path length, 90% confidence area and maximum CoP speed were significantly increased in talk compared to text and control. 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.

The Specificity of Cognitive-Motor Dual-Task Interference on Balance in Young and Older Adults

“…We used tablet-based cognitive tasks in part because of the increasing role of devices in daily life. Indeed, other cognitive-motor dual-tasking studies have found that using mobile devices can impact postural control for both younger and older adults ( Cho et al, 2014 ; Nurwulan et al, 2015 ; Laatar et al, 2017 ; Bruyneel and Duclos, 2020 ; Hsiao et al, 2020 ; Onofrei et al, 2020 ). Future work with larger samples is needed to extend investigations into the specificity of cognitive-motor dual-task interference on balance to more realistic tasks people complete on mobile devices.…”

Satisfaction in parturients receiving epidural analgesia after prenatal shared decision-making intervention: a prospective, before-and-after cohort study

“…Second, childbearing women were in relatively young age among both groups. Young people often have the ability to use smartphone to watch videos via QR code Table 2 Subjects' baseline characteristics stratified by interventions Table 3 Percentage of score increasement in the comprehension a and satisfaction b between study groups [21]. Third, pregnant women have to schedule prenatal visits every 2 weeks after their 28th week of gestation; therefore, they have oppurtunities to discuss with anesthesiologist in their routine visits in hospital.…”

Üniversite Öğrencilerinde Akıllı Telefon Bağımlılığı ile Kas-İskelet Sistemi Ağrısı, Depresyon ve Uyku Kalitesi Arasındaki İlişki

“…Akıllı telefon kullanımının ayakta dururken ve yürürken spinal duruş ve pelvik pozisyon üzerindeki etkisini araştıran yakın zamanlı bir çalışmada, akıllı telefon kullanımının sagital ve frontal omurga parametrelerinde lomber lordoz gibi önemli değişikliklere yol açtığı gösterilmiştir (28). Sağlıklı genç yetişkinlerde akıllı telefonla konuşmak ve mesajlaşmak postural stabiliteyi önemli ölçüde etkilemektedir (29). Başın uzun süre öne doğru eğilmesi, alt servikal vertebralarda servikal lordozun azalmasına ve üst torasik vertebralarda kifozun artmasına neden olabilir.…”
