Mobile technology and cumulative trauma symptomology among millennials

Introduction Technology use among the millennial population is increasing and related postural compromise may lead to cumulative trauma disorder symptomology. The aim of this study was to explore trends of hand-held mobile technology use and upper extremity cumulative trauma disorder symptomology among a sample of millennials. Methods A convenience sample of graduate students ( n = 42) was used for the study. Demographic and technology use information was obtained through self-report using the smartphone screen time tracking feature. Cumulative trauma disorder symptomology was assessed through administration of various orthopedic special tests. Results On average, participants spent 2 h and 23 min per day using hand-held mobile devices. Out of 42 participants, 54.8% tested positive for at least one orthopedic special test. The symptomatic group spent 2 h and 29 min using hand-held mobile devices, while the asymptomatic group spent 2 h and 4 min. The most common positive orthopedic special tests were Finkelstein’s test ( n = 19; 36%), hyperabduction (Wright’s) test ( n = 13; 25%), and the elbow flexion test ( n = 10; 18.9%), indicating symptoms associated with De Quervain’s tenosynovitis, thoracic outlet syndrome, and cubital tunnel syndrome, respectively. Discussion Results were consistent with prior research on time spent using hand-held mobile technology and cumulative trauma disorder among millennials. Additionally, a difference in mean time spent using mobile technology between the asymptomatic and symptomatic groups was found, suggesting a relationship which warrants further research.
