      Objective: Assess the association between leisure inline skating practice and knee joint functionality in adults in Lima, Peru. Methods: This analytical cross-sectional study took place in Lima, Peru. The population involved 120 adults of both sexes who practiced leisure activities such as running, roller skating and cycling. The knee functionality has been evaluated by IKDC (International Knee Documentation Committee). In addition, the lower limb alignment was analyzed with PAS program (Postural Assessment software). Information like age, sex and activities features were analyze through surveys. For the analysis, it was used the T Test of Student for a mean difference and a Multiple Linear Regression Analysis for the confusing variable control. Results: There were 120 survey respondents between 36,1 years old. The 40,3% of the population did skating and the rest of population did other activities (running or cycling). After comparing the knee alignment level, the roller skaters had an average of 4,75 points less than the non-roller skaters (IC95%: -9,12 a -0,39). This difference was significant even after adapt the effects of age, sexes, lateral dominance and knee alignment. Conclusion: The roller skaters present a less knee functionality than the non-roller skaters. This could show some movements or posture adopted by roller skaters a damage for their knees.

      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.

    • Efectos de un programa de pausa activa más folletos informativos en la disminución de molestias musculoesqueléticas en trabajadores del área administrativa de una institución pública en Lima, Perú.

      Universidad Peruana de Ciencias Aplicadas (UPC) (Universidad Peruana de Ciencias Aplicadas (UPC), 2017-02-22)
      Purpose: To demonstrate the effect of an active pause program plus informative leaflets in reducing the perception of musculoskeletal discomfort on administrative employees from a public entity of Lima, Peru. Materials and methodology: A quasi-experimental non randomised study on administrative employees from two branches of a public institution was conducted. The initial and final measurement included frequency and intensity of musculoskeletal discomfort using Nordic Musculoskeletal Questionnaire NMQ. The intervention after the initial measurement was for eight weeks. A total of 372 individuals were invited to participate, 135 individuals in the intervention group, who received an program active pause supervised and informative leaflets and 127 in the control group, who received only informative leaflets. The program consisted on breathing, stretching and muscle warm-up exercises. Furthermore, information leaflets were handed once a week. Outcome: Average participants’ age was 38 years old. The physical anatomy structures most affected were the neck and mid-back area. During the last seven days the intervention group suffered a decreased of 20% regarding prevalence of the musculoskeletal discomfort on the neck (p<0,001), and 17% on the low-back area (p<0,001). The controlled group showed a decrease on prevalence only in the mid-back area (p=0,029). In terms of discomfort severity, in the final measurement, the intervention group experienced a greater decrease in all areas included in the NMQ (p<0,05). Conclusion: Active pause program plus leaflets decreased musculoskeletal discomfort in office employees. Therefore, it can be implemented at other public or private entities with similar characteristics.
