Aim: To determine the effects of mobile phone use on fine motor functions, neck, and upper limb disability values.
Methods: Time duration of mobile phone use was recorded for a week. Rapid Upper Limb Assessment (RULA) was used to determine the risk level about posture while texting message on phones. Neck Disability Index (NDI) for neck pain and functional disability of neck on activities of daily life, Disabilities of the Arm, Shoulder, and Hand-Function/Symptom (DASH-FS) for the limitation in the functions of upper limb, Jebson Taylor Hand Function test for fine motor function.
Results: Two hundred and seventy individuals (141 women, 129 men) whose mean ages were 21,48±1,86 years were included. While a significant correlation between duration of phone use and NDI score was specified (r=0,172; p=0,005), no significant correlation was found between duration of phone use and DASH-FS scores (r=0,092; p=0,130). It was found that there was a negative significant relationship between the duration of phone use and the total function score of the left hand and throwing small objects (p<0,01). According to RULA 95,6% of individuals have unacceptable phone usage postures, but no significant relationship was found between ergonomic risk level and NDI values, DASH-FS values, and hand functions (p>0,05).
Conclusion: Although increased duration of phone use could cause neck problems, manual ability may be positively affected. In addition, since most participants have a poor posture while using a mobile phone, it is thought that this may be a risk factor for more musculoskeletal problems in older ages.
