“…Obviously, prolong neck bending will alter cervical curvature and creating undue stress and experiencing constant discomfort over adjacent structure 11 . Even though, there is moderately weak correlation between addiction and upper back, arm discomfort the results is consistent with previous study 12,13,14 . The limitation of this study is the small respondent size which represents at one shopping mall in Kuala Lumpur.…”

Background and objectives: Smartphone is ubiquitous in this digital era and the remarkably evolved of technologies is an evident of heavy usage of such gadget in daily life. Recent evidence indicate that there is significant association between upper arm discomfort and smart phone user. However, there is limited finding on the smart phone addiction on upper body discomfort. Therefore, this study aimed to investigate level of smartphone addiction among Kuala Lumpur young adults. Methods: This is a cross sectional analytical type of study. Self-administer questionnaire is used to determine the level of smartphone addiction level and body discomfort. Results: A total of 290 subjects (80.7% females and 19.3% males) are involve in this study. Majority of respondents (69.7%) suffer mild smartphone addiction and there is significant association with neck and shoulder discomfort (p<0.05). Respondent's belief that the discomfort experience were due to prolonged smartphone usage (74.1%). Furthermore, 84.5% of respondents noted that discomfort experienced was relieved when not using smartphone. There is significant differences between between time spent on smartphone with age categories, gender, occupation and smartphone addiction level (p<0.05). Conclusion: Time spent on smartphone is consistent to smartphone addiction level. A higher level of smartphone addiction will increase the risk in developing upper body discomfort.

“…reported that while using a smartphone, individuals with minor neck pain bent their neck slightly more than those without neck pain, although the causal relationship could not be identified . In this regard, Lee and Seo (2014) noted that a higher degree of smartphone addition may lead to a reduction in the ability to recognize neck posture (Lee and Seo, 2014). These studies suggest that the use of a smartphone can impair the sensory ability to recognize neck posture, thereby becoming a factor that causes pain by bending the neck at a higher angle.…”

| Abstract |1 )PURPOSE: The purpose of this study was to examine changes in the neck flexion angle according to posture while using a smartphone and the duration of smartphone usage. METHODS:The subjects in this study were 16 healthy young students in their 20s. The subjects wore a cervical range of motion instrument. They were instructed to use a smartphone while standing, sitting on a chair, and sitting on the floor. In all postures, they could use the smartphone and use their arms freely while keeping their back connected to the wall or the back of the chair. When sitting on the floor, they assumed a cross-legged position. The neck flexion angle was measured at zero, three, six, and nine minutes for each posture. RESULTS:Neck flexion is affected by the posture while using a smartphone (p<.05). Neck flexion in the standing position is larger than that in the sitting on the floor position.Neck flexion was affected by smartphone usage duration (p<.05). In general, as usage time increases, the neck flexion angle increases as well. CONCLUSION:This study suggests that using †Corresponding Author : lovewisd@u1.ac.kr This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. smartphone in the standing position and for a short period of time is a method to reduce the neck flexion angle.

Purpose: Individuals are utilizing smartphones for different tasks on a daily basis. Prolonged smartphone usage might lead to deficient postures such as forward head posture and rounded shoulders. The purpose of this study was to look at the impact of the heavy use of smartphones versus light use on Joint Position Error (JPE), Craniovertebral Angle (CVA), and balance measures. Method: Thirty healthy participants were recruited in this study, and they were divided into two groups: light use (phone use<4 h/d) and heavy use (phone use>4 h/d). Subjects were assessed for cervical repositioning errors using the JPE test. Forward head posture was measured by CVA. Dynamic balance was assessed using the Biodex stability system. Results: There was a significant increase in JPE of both right and left rotation in the heavy-use group compared with that of light-use group. Also, there was a significant increase in balance indices in the heavy-use group. However, there was no significant difference in CVA between groups. Conclusion: Our study showed that prolonged duration of smartphone use could negatively affect cervical proprioception and dynamic balance ability. Further considerations are required to outline the negative impacts of heavy usage of smartphones and to implement preventive measures.
