“…Studies examining the effect of smartphone use and addiction on the median nerve and f lexor pollicis longus tendon have been conducted with healthy people. [14][15][16][17][18][19] In a cross-sectional study, the use of electronic devices, including smartphones, was examined in people with CTS symptoms, and it was emphasized that conducting case-control studies or prospective studies with nerve conduction testing was valuable. [20] The current study, to the best of our knowledge, is the first study comparing smartphone use and addiction in CTS case and control groups in the literature.…”

“…[14] As a result, a significant decrease in sensory nerve conduction velocity, which is a wellknown early parameter of CTS, is an indicator that excessive smartphone use affects the median nerve. [15] Although there are cross-sectional and experimental studies examining the relationship between smartphone use, smartphone addiction, and CTS, [14][15][16][17][18][19][20] no case control study exists in the literature. To the best of our knowledge, this is the first study investigating smartphone use and addiction in CTS case and control groups.…”

Objectives: This study aims to investigate the use of and addiction to smartphones in individuals with and without carpal tunnel syndrome (CTS). Patients and methods: The cross-sectional study included a total of 404 participants (286 females, 118 males; mean age: 39.7±11.6 years; range, 16 to 75 years) who applied to the Neurology Department of the Fırat University Faculty of Medicine, between April 2019 and October 2019. The participants were divided into two groups: 202 patients diagnosed with CTS were included in the case group, and 202 patients and their relatives who did not have hand and wrist complaints were included in the control group. The diagnosis of CTS was made by evaluating the history, physical examination, and electromyography findings. Data were collected with participant information forms and the Smartphone Addiction Scale. Results: It was found that the risk of CTS increased 1.022 times with a one-unit increase in the SAS score and 1.292 times with a 1-h increase in daily smartphone use. Conclusion: Smartphone addiction can be considered as a potential risk factor for CTS; however, the effect of smartphone addiction on CTS severity was not examined in this study. The relationship between disease severity, smartphone use, and smartphone addiction in CTS patients requires further investigation to provide clarification on this issue.

“…In this context, faulty postures such as prolonged wrist flexion and repeated thumb use may affect median nerve 19) . Ilik et al 41) reported that repeated wrist-flexion and extension movements may have resulted in the larger median nerves that were noticed among high-frequency smartphone users. Wrist-flexion or extension motions are also related to increased pressure in the carpal tunnel resulted in decreased space for the median nerve inside 46) .…”

Evaluating hand performance and strength in children with high rates of smartphone usage: an observational study

This study investigated the interaction effects between the levels of smartphone use and hand dominance on handgrip, pinch strengths, and functional hand performance in children. [Participants and Methods] A total of 60 children aged between 9 and 15 were assigned into two groups: Group A (high-frequency smartphone users) and Group B (low-frequency smartphone users). Use levels were determined according to the smartphone addiction scale-short version. A hand dynamometer and pinch gauge were used to measure handgrip and pinch strength respectively. Functions of the upper extremity and hand were scored using the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire. [Results] Group A participants had reduced measurements in hand grip and pinch strength, especially in the dominant hand. However, Quick Disabilities of the Arm, Shoulder, and Hand scores indicated that hand function was decreased in the dominant hand whether the child was a high-or low-frequency smartphone user. [Conclusion] Results indicated that high levels of smartphone use diminished hand and pinch-grip strengths as well as and hand function. That is, hand and pinch-grip strengths were reduced in the dominant hands of high-frequency smartphone users. However, hand functions were affected in the dominant hands among both high and low-level smartphone users.

“…When performing pinch grip and thumb opposition with the wrist in ulnar deviation, a thickening of the circumferential surface area of the median nerve was noted in yet another study 30 . In the present study, we also observed an increase in pinch grip for the dominant hand, with a mean of 9.33±1.57 kg compared to 8.27±1.27 kg for the non-dominant hand (p<0.001).…”

Background and Aim The adverse effects of smartphone size and weight on the hand and hand function have not been studied extensively. This study aimed to investigate the changes to the flexor pollicis longus tendon and median nerve using diagnostic ultrasound for high and low addiction smartphone users. Methodology In this cross-sectional study, 54 healthy male university students were divided into two groups according to the Smartphone Addiction Scale: high and low users. Demographic data, hand grip strength (kg), pinch strength (kg), and smartphone weight, length and width were measured and recorded. Diagnostic ultrasound examination determined the cross-sectional area of the median nerve (mm2) and flexor pollicis longus tendon (mm2) of the dominant and non-dominant hand. Result The cross-sectional area of the median nerve was significantly higher in the high-user group (7.4±1.3 mm2) than the low-user group (6.7±1.0 mm2). The correlation of phone weight, length and width with median nerve area was respectively positive, higher and significant (0.718, 0.747, and 0.733; p<0.05). The flexor pollicis longus tendon in the mid-thenar region was moderately positively correlated with phone length (0.430; p<0.02) for high addiction smartphone users. Conclusion The findings of the current study demonstrates that change to the median nerve and flexor pollicis longus tendon, could be linked to the width, weight and length of the smartphone and high addiction.
