Abstract
This systematic review aimed at evaluating the risk factors for cervical muscles and neck complaints associated with touch screen devices use. PubMed central, Science direct, Google scholar and Springer link were searched. The methodological quality of included studies was assessed. Strength of evidence for risk factors was determined based on study designs, methodological quality and consistency of results. This review demonstrates that the prevalence of musculoskeletal complaints among mobile device users ranges from 1.0% to 67.8% and neck complaints have the highest prevalence rates ranging from 17.3% to 67.8%. This review also finds some evidence for neck flexion, frequency of phone calls, texting and gaming in relation to musculoskeletal complaints among mobile device users. People using mobile touch screen devices (MTSDs) have been exposed to the musculoskeletal disorder because of physical risk factors. Inconclusive evidence is shown for other risk factors such as duration of use and human-device interaction techniques due to inconsistent results or a limited number of studies
