Abstract

The aim of this report was to give ergonomic recommendations in order to prevent musculoskeletal symptoms/disorders among young people due to intensive texting on mobile phones. In a study of 56 Swedish young adults (19-25 years, 41 with musculoskeletal symptoms in neck and/or upper extremities and 15 without symptoms) registration of thumb movements with electrogoniometry, muscle activity with electromyography and observation of texting technique were conducted during texting on mobile phones. The results showed differences in physical load between the group with musculoskeletal symptoms and the group without symptoms. There were also found differences in muscle activity and kinematics between different texting techniques. These differences could not be explained by the asymptomatic group having symptoms but may be a possible contribution to their symptoms. According to these results it can be recommended to support the forearms, to use both thumbs, to avoid sitting with the head bent forward and to avoid texting with high velocity in order to prevent musculoskeletal disorders when using mobile phones for texting.
