Abstract

Background: Surfing is a sport that requires alternating high, medium, and low intensity at one time. Surfing combines three phases, namely paddling, pop-up, and wave-ride. The surf pop-up phase is characterized by a change from a paddling position to a standing position on the surfboard in one dynamic motion. During this transition, a surfer must move 75% of his body weight in less than one second. Pop-up movement is a unique challenge for the human motor system because it must be done quickly, with sufficient strength, on a moving and unstable surface that requires the readiness of the bio motoric component to avoid injury. This study aimed to see the relationship between core muscles, leg arches, hamstring, and lumbar flexibility on pop-up ability among surfers. Methods: The research uses analytic observational with a cross-sectional approach. The number of samples was 80 people with inclusion criteria, men aged 20-40 years and at least one year of surfing experience. Core muscles were measured using the curl-up test, the footprint test measured leg arches, hamstring flexibility by the sit and reach test, lumbar flexibility by the modified Schober's test, and pop-up ability using the time to pop-up. The research was conducted in Badung regency. Results: This study showed a significant and strong relationship between core muscles (r= 0,57, p-value< 0.001), leg arches (rs= 0.33-0.43, p-values= 0.009 - <0.001), hamstring and lumbar flexibility (rs= 0.31-0.50, p-values= 0.013 - <0.001) on pop-up ability among surfers. Conclusion: There were significant relationships between the core muscles, leg arches, hamstring and lumbar flexibility on pop-up ability among surfers.

Abstract

Background: In recent years, backpack use has drastically increased, especially among elementary school students. This has led to an increase in musculoskeletal complaints, such as shoulder pain, due to the duration of use and the weight of the backpacks. This study investigated the correlation between the duration of use and the weight of backpacks on shoulder pain complaints in grades IV-VI elementary school students. Methods: This study employed an analytical observational research design with a cross-sectional study design. The inclusion criteria for this study were students aged 10-12 years old, using backpacks with shoulder straps, walking to and from school. In contrast, the exclusion criteria were injuries in the shoulder region. The sampling technique employed in this study was probability sampling, specifically simple random sampling. The research was conducted at Islamic Elementary School 1 and 2 in Karangasem, Bali. The sample size was calculated using the Lameshow formula, resulting in 106 samples. Results: Based on bivariate analysis using Pearson’s Correlation Coefficient (r), the p-value obtained was 0.000 (p< 0.05) for both independent variables, with correlation coefficients of r = 0.570 for the duration of use variable and r = 0.709 for the backpack weight variable. Based on multivariate analysis using Multiple Linear Regression in the F-test or simultaneous test, the p-value obtained was 0.000 (p < 0.05). Conclusion: Based on the research results, it can be concluded that there was a correlation between the duration of use and the backpack's weight on shoulder pain complaints, both partially and simultaneously.

Abstract

Background: Low back pain is a musculoskeletal disorder caused by incorrect ergonomic conditions at work. It is located at the inferior gluteal fold and the coastal border and lasts more than 24 hours. This study aimed to determine the prevalence of low back pain complaints in handcrafters. Methods: This research used an observational analytic design with a cross-sectional approach. The sampling technique used was purposive sampling. The inclusion criteria for this study were handcrafters of serati banten aged 45-55. In contrast, the exclusion criteria were injuries in the lower back region. The total number of respondents who participated in this study was 50 people. The research location was in Gianyar, Bali. Data was collected from January to October 2023. Data were collected by measuring VAS and REBA. VAS measured the severity and relief of pain, while the REBA questionnaire analyzed work posture. Results: The results of research regarding the prevalence of low back pain in handcrafters of serati banten in Gianyar Regency based on internal factors showed the majority experienced low back pain of mild intensity (60%), and external factors showed that the majority of pain incidents occurred in respondents with a working period of >5 years (52%), working in a sitting position (56%) with moderate risk working postures (64%). Conclusion: The frequency of low back pain occurrences due to external factors was dominated by respondents with less than five years of working experience who worked in a sitting position with a medium-risk work posture.

Abstract

Background: This study aimed to examine the psychometric performance of the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) version Indonesia used in pre-elderly and older adults in Indonesia with knee osteoarthritis and hip osteoarthritis. Methods: This study obtained samples from 124 pre-elderly and elderly individuals affected by knee and hip osteoarthritis in the Denpasar, Badung, and Gianyar areas to check the reliability and validity of the Indonesia WOMAC from Karsten et al. (2019). Knee and hip osteoarthritis were examined using the American College of Rheumatology (ACR) clinical criteria. Results: The Indonesian WOMAC was valid with a score of (0.809-0.964) for knee osteoarthritis, (0.870-0.982) for hip osteoarthritis, and (0.744-0.944) for knee osteoarthritis and hip osteoarthritis. It is reliable with Cronbach’s alpha score of (α = 0.992) for knee osteoarthritis, (α = 0.996) for hip osteoarthritis, and (α = 0.980) for knee osteoarthritis and hip osteoarthritis in pre-elderly and elderly patients. Conclusion: Based on the research results, the Indonesian WOMAC was valid and reliable for knee and hip osteoarthritis and is used in pre-elderly and elderly patients.
