“…It seems that higher frequency of right-handed individuals than left-handed individuals and the higher frequency of performing physical activities with the right hand than left hand in all societies are the reason for higher prevalence of this syndrome in right hand [29][30][31]. In this study, this disorder was most common in patients aged 40 to 60 years old.…”

“…Ulnar neuropathy can occur at the wrist just proximal to, within, or distal to Guyon's canal [30]. Ulnar nerve compression at Guyon's canal may be associated with an occupational disease in which the nerve is exposed to repetitive blunt trauma or high frequency vibration [31]. Guyon's canal syndrome, due to occupational overuse, has been attributed to prolonged flexion or extension of the wrist and repeated pressure on the hypothenar eminence [32].…”

Objectives: Repetitive microtrauma or overuse injuries may often affect upper extremities of the long term computer users. The aim of this study was to compare sensory nerve conduction velocities (SNCV) for median, radial and ulnar nerves in the wrist of computer users with the same parameters in controls who do not use computers regularly. Material and Methods: Twenty one male computer users (age: mean (M) = 28.3 years ± standard deviation (SD) = 7.5 years) and 21 male control subjects (age: M±SD = 24.1±4.6 years) were recruited for the study. Limb length and the perimeters of the dominant arm and forearm were measured for each subject. The neurophysiological study consisted of measuring sensory nerve conduction of the median, ulnar and radial nerves. Results: The sensory conduction velocities of both median and ulnar nerves were significantly delayed in the dominant arm of the computer users compared to the controls. In addition, sensory conduction velocity of the median nerve was significantly delayed in the dominant extremity of the computer users compared to their non-dominant extremity. Conclusions: This study shows that computer users have a tendency toward developing median and ulnar sensory nerve damage in the wrist region. Mechanism of delayed SNCV in the median and ulnar nerves may be due to sustained extension and ulnar deviation of the wrist during computer mouse use and typing. Reduced SNCV changes were more apparent on the dominant side of the median nerve. This may indicate the increased neural deficits related to an increased use of the dominant side. Further investigation is needed to determine how to reduce potential risk factors at this stage in order to prevent development of median or ulnar neuropathy in the long term computer users.

Abstract.[Purpose] The present study was intended to examine the effect of excessive use of smartphones on the carpal tunnel and median nerve in the wrist. [Subjects and Methods] A questionnaire was used to determine the degree of addiction to smartphones in 125 normal adults who used smartphones; then, ultrasonography of the median nerve, Phalen's tests, and reverse Phalen's tests were conducted on the subjects.[Results] Based on the results of the experiment, the thickness of the median nerve did not change in relation to duration of smartphone use per day, duration of continuous smartphone use, periods of the use of smartphones, or the degree of addiction; however, statistically significant shortening of time to wrist tingling was identified in the Phalen's tests and reverse Phalen's tests conducted to examine clinical symptoms. [Conclusion] In conclusion, excessive use of smartphones may act as a cause to trigger carpal tunnel syndrome due to pressure on the carpal tunnel in the wrist joint; thus, precautions are necessary when using smartphones.
