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 Citation - WoS: 1Citation - Scopus: 1The Effect of Neck Mobilization Vs. Combined Neck and Lumbar Mobilization on Pain and Range of Motion in People With Cervical Disc Herniation: a Randomized Controlled Study(Elsevier, 2025) Ozdincler, Arzu; Aktas, Dogan; Reyhanioglu, Duygu Aktar; Ozturk, Basar; Aktar Reyhanioglu, DuyguBackground: To assess the effectiveness of Kaltenborn-Evjenth Orthopedic Manual Therapy (KEOMT) applied to cervical-only mobilization versus both lumbar and cervical regions on pain intensity and range of motion (ROM) in individuals with cervical disc herniation. Methods: Thirty-three participants were enrolled in the study. The patients were randomly assigned to two groups. Group A received cervical-only KEOMT, while Group B received combined lumbar and cervical KEOMT. Interventions were administered three times a week for four weeks. Pain was measured using the Visual Analog Scale (VAS), ROM was assessed for flexion and lateral flexion, and Neck Pain and Disability Index (NPDI) and Short-Form 36 Health Survey (SF-36) were used for evaluation. Results: In intra-group measurements, a statistically significant difference was observed in all parameters of pain, ROM, disability, and quality of life for the mobilization methods applied in both groups (p < 0.05). Group B demonstrated significantly greater improvements in ROM/flexion, pain, and disability outcomes compared to Group A in inter-group measurements (p < 0.05). Physical and emotional sub-groups of quality of life measures also favored Group B in intergroup analysis (p < 0.05). However, the power values for ROM and quality of life parameters were found to be low. Conclusions: The cervical plus lumbar KEOMT technique is more effective than cervical-only mobilization in improving pain and disability. However, low power values for ROM and quality of life suggest these results may lack clinical significance, warranting further research.
