    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.

    Moscoso Porras, Miguel Giancarlo; Sánchez Bardales, Isabel (Universidad Peruana de Ciencias Aplicadas (UPC), 2018-01-15)
    Introduction: Children diagnosed with attention deficit and hyperactivity disorder (ADHD) commonly present developmental coordination disorders (DCD). However, current evidence is still unclear about the relationship between having ADHD and presence of DCD. Objective: To determine the association between DCD in children and ADHD. Materials and methods: A matched retrospective cohort study was conducted in Lima, Perú. Participants were children between the ages 6 and 12 years old. The sample included 160 participants, from which 32 were previously diagnosed with ADHD. A 1:4 matching was made recruiting healthy children closely related to the one that had ADHD, such as family or friends of same age and sex. The DCDQ’07 questionnaire was used to identify DCD and the SNAP-IV behavior scale to rule out ADHD in the healthy group. Mixed regression models were used to account for matching and to control confusion. Results: Data from the 160 participants were analyzed. DCDQ’07 scores in Children with ADHD were 10.3 points lower than the children without ADHD (CI 95%: -15,3 – -5,4, p<0,001). Within DCDQ’07 specific areas, children with ADHD scored in average 4.4 points less in general coordination (IC 95%: -6.1 – -2.8, p<0.001), 3.3 points less in fine motor skill (CI 95%: -4.9, – -1.7 p<0.001) and 2.6 points less in control during movement (CI 95%: -4.6 – -0.6, p<0.001) in comparison to those without ADHD. These differences remain significant in the model after adjusting for preterm birth, low birth weight and chronological age. Through the conditional logistic regression analysis, in adjusted and unadjusted models, children had 6 times the probability of developing DCD when compared to those without ADHD (CI 95%: 2,6 – 15,5, p<0,001). Conclusions: We found that the average score for DCD in the children diagnosed with ADHD was lower than the ones without ADHD. This suggest that these children have a greater difficulty with general coordination and fine motor skills which may affect the development of their everyday activities.

    Becerra Bravo, Giancarlo; Retamal, Milagros; Segura, Eddy R.; Navarrete Vilca, Talia Brigitte (Universidad Peruana de Ciencias Aplicadas (UPC), 2017-06-28)
    Background: Hospital admission in the elderly has an impact on functional capacity and quality of life. This study aimed to identify the association between the degree of functional dependence and degree of dysmobility in the elderly adult patient. Methods: We reviewed 180 medical charts of subjects admitted within the november-december 2013 period. Functionality was assessed with the Katz and Barthel Indexes while the degree of dysmobility was assessed with the etapification of the dysmobility scale. We analyzed the dichotomized dysfunction as the outcome variable in a GLM Log-Poisson regression to calculate crude and adjusted Prevalence Ratios (PR). Results: 50,6% were women and the mean age was 79,5 years with an standard deviation of 8,3. A total of 46,7% were categorized as Katz G (completely dependent), while 3,9% had an 1A or 1B dysmobility staging (biped). Subjects with Katz C/D/E stages had an aPR: 23,9 [95%CI: 3,1-185,6] to exhibit 1/2 (biped) dysmobility stage, while subjects with Katz A/B had an aPR: 100,0 [95%CI: 14,9-670,5], in both cases compared to subjects with Katz F/G stages. Conclusion: There is an association between functionality and dysmobility among elderly hospitalized patients at admission. We recommend all health professionals take into account this relationship during the comprehensive physiotherapeutic evaluation of the elderly patient in order to better individualize their assessment and treatment.

    Introduction: To determine the association between patellar tendon angle (AITP) and the presence of anterior knee pain (DAR) and the prevalence of DAR in college athletes. Materials and methods: Cross-sectional study of college athletes. The presence of DAR was detected using the Anterior Knee Pain Scale by Kujala and AITP was calculated by analyzing a photograph of both legs with Kinovea program ®. Each knee was considered as a sample. The prevalence ratio between the DAR and the AITP was calculated using Poisson regression robust Results: 143 subjects were evaluated, therefore, 286 knees, where 176 (61.5%) had anterior knee pain (DAR). The AITP was ranked in quartiles. To analyze was joined second and third quartile so was obtained a midquartile (9° and 14°). It was found that AITP fewer than 9° is 1.34 (95% CI, 1.09 - 1.65) more likely to have DAR, and AITP greater than 14° is 1.35 (95% CI; 1,09- 1.69) more likely. Conclusions: Athletes with AITP fewer than 9 ° or greater than 14 ° are more likely to have DAR. It is recommended that the professional considers the inclination patellar tendon angle in the evaluation

    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.

    Aim: To determine the shoulder pain level and associated factors among wheelchair users. Material and Methods: A cross-sectional study was conducted among wheelchair users who attend a Rehabilitation Institute, at the Amputated and Spinal Cord Injury Departments. A census was conducted through a self-administered survey including the Wheelchair Users’ Shoulder Pain Index (WUSPI) questionnaire. For data analysis, multiple linear regression was used. Results: The population comprised 351 individuals, the mean age was 43.78 ± 14.17 years, 47.58% were female; 81.48 % had spinal cord injury. Shoulder pain prevalence was 100%. The adjusted model showed that “spinal cord injury” diagnosis, manual wheelchair; time spent in the wheelchair, where the chair was acquired and the number of transfers during the weekend—were statistically associated with the presence of shoulder pain (p<0.05). Conclusions: Shoulder pain is associated with medical diagnosis, type of wheelchair, hours spent in the wheelchair, where the patient acquired the chair and the number of transfers in the previous weekend. These findings may be useful to screen at-risk sub populations.
  • Asociación entre Tenosinovitis de Quervain y horas de uso de “Smartphone” en alumnos de la facultad de Negocios de la Universidad Peruana de Ciencias Aplicadas

    Universidad Peruana de Ciencias Aplicadas (UPC) (Universidad Peruana de Ciencias Aplicadas (UPC), 2017-02-02)
    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.
  • Cervicalgia, discapacidad cervical y factores asociados en estudiantes y músicos del Conservatorio Nacional de Música

    Universidad Peruana de Ciencias Aplicadas (UPC) (Universidad Peruana de Ciencias Aplicadas (UPC), 2017-02-02)
    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.
