Objectives: To determine the association between De Quervain Tenosynovitis (QT) and the hours of Smartphone usage and to explore other potential associated factors. Material and methods: We performed a cross-sectional study in university students. QT was measured through Finkelstein’s test and hours of smartphone usage were determined through a survey. Participants were Smartphone users and students from the business faculty at a local university. Those who reported having an actual injury or in the last year in their hands (fractures, neurological injury, amputation) or reported using a Smartphone for less than a year were excluded. Bivariate associations were tested with Chi squared and Student’s t tests. We calculated the Prevalence Ratio (PR) through Poisson regression models to control for potential confounders. Results: Out of the 515 recruited participants, 68, 68% were women; the average age was 20±2.4 years. Regarding QT, 58, 95% of the population presented a positive sign in Finkelstein’s test. The total mean of hours of Smartphone usage was 7.2±3.4. After adjusting for age and gender, we did not find an association between QT and hours of Smartphone usage (PR: 0.99, IC95%: 0.96-1.01). Other factors tested like age, gender, dominant hand or having a job were also not associated to QT (all PRs>1, p>0.05). Conclusions: We did not found an association between QT and hours of Smartphone usage in university students. Additionally, other factors like age, gender, dominant hand or having a job were not associated to QT.

Objectives: to determine the presence of neck pain and the neck disability index in the students of the National Conservatory of Music as well as to evaluate their associated factors. Materials and methods: A cross-sectional study was conducted in Lima, Peru. The population was formed by students from the National Conservatory of Music, who were evaluated through a self-report survey of neck pain in the last 3 months, neck disability, as well as evaluating the presence of temporomandibular disorders. The association was assessed by calculating the adjusted prevalence ratios. Results: A total of 211 individuals were included, mean age ± standard deviation was 22.0 ± 2.0 years and the majority were male (70.0%). The neck pain prevalence was 69.4%; 45.6% had moderate disability and 45.0% presented mild disability. Playing bowed string instruments was associated with neck pain (RP 1.34 95% CI 1.15 - 1.57). An association between Temporomandibular Disorders (TMD) and neck pain(TMD moderate-severe) was found (RP 1.65 95% CI 0.99 - 2.75). The association between TMD with neck disability (TMD (absent-slight) was demonstrated: RP 2.81 CI 95% 1.00-7.84 and p = 0.048; TMD Moderate / Severe: RP 3.86 CI 95%: 1.39- 10.70 and p = 0.009) Conclusion: The association between neck pain and the practice with bowed string instruments was corroborated. An association of TMD with neck pain and neck disability was found. This also supports the association with neck disability. The active pauses and physical activity programs are tools that help to reduce neck pain. This leads to have less people predisposed to suffer neck disability.
