Article Investigating Text Neck Syndrome and Duration of Mobile Phone Use, Muscle Activity, Hand Grip Strength, Posture, and Disability(Elsevier Sci Ltd, 2026) Yasaci, Zeynal; Zirek, Emrah; Mustafaoglu, Rustem; Ozdincler, Arzu RazakNeck and shoulder musculoskeletal symptoms related to smartphone use are becoming increasingly prevalent, yet the underlying mechanisms including smartphone usage duration, muscle activity, hand grip strength, posture, and disability remain incompletely understood. This study examined the interaction between text-neck syndrome and factors such as smartphone usage duration, muscle activity, hand grip strength, posture, and disability. Forty participants (Text Neck group: n = 18; 14 females or Control group: n = 22; 15 females) underwent neuromuscular assessment. Surface electromyography measured bilateral muscle activity in the upper trapezius (UT) and abductor pollicis brevis (APB) muscles during smartphone use. Secondary outcomes included the Visual Analogue Scale (VAS) to assess pain intensity, hand grip strength, New York Posture Rating Scale (NYPRS), Neck Disability Index (NDI), and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. The Text Neck group demonstrated significantly higher smartphone use (p < 0.001), higher texting time (p = 0.006), and lower muscle activation at activity in the dominant APB (p = 0.011), dominant UT (p < 0.001), and non-dominant UT (p = 0.008). These findings provide novel insights into how excessive smartphone use alters muscle function and postural alignment in individuals with text-neck syndrome. Understanding these mechanisms may inform targeted prevention and rehabilitation strategies to mitigate musculoskeletal risk associated with modern technology use.Article The Relation of The Duration of Work in Dentists With Postural Problems, Range of Motion and Pain(Bezmialem Vakif Univ, 2020) Tekin, Demet; Koksal, MesutObjective: The aim of this study is to determine the relationship between cervical and lumbar range of motions, pain and postural problems with the time spent in the occupation in dentists. Methods: A total of 56 dentists (27 males, 29 females), participated in this research as a volunteer (age=29.55 +/- 9.5 years). Firstly, the participants were divided into 3 groups according to the working years in their life and the time spent at unit during the day; they were also divided into 2 groups according to the intermittent or uninterrupted working conditions during the day. Cervical and lumbar joint range of motions were measured to determine limitations. The McGill pain scale survey was used to evaluate the pain. Kruskal Wallis and Mann-Whitney U tests with a posthoc Bonferroni test were used for all statistical analyses. Results: It was seen that the cervical and lumbar joint range of motions decreased, and the postural deformities in the spine and knee were observed and the level of pain increased significantly in comparatively to the excess of the time spent in the profession. However, in the analysis according to the time spent at the unit during the day, only the decrease in the range of motion of the regions was determined with the increase of the time spent at the unit during the day. Conclusion: With the increase in the working years in the dentists, it was revealed that the limitation of the range of motion increased and posture disorders and pain were formed. It is thought that all these problems will be caused by working in non-ergonomic environments for a long time. In this respect, it is important to include experts in the field of physiotherapy in the courses given under the name of preventive medicine. As a result, it can be said that the health problems encountered with the increase in time spent in the profession have increased.
