Abstract

Introduction: Around 60-80% of individuals experience low back pain in their lifetime, often leading to disability. The Roland-Morris Disability Questionnaire (RMDQ) is a tool used to assess disability caused by low back pain, measuring its impact on daily activities. To ensure its effectiveness, it is crucial to test the questionnaire's validity and reliability in different cultural contexts. Methods: This study employed a descriptive survey method and a cross-sectional design with a purposive sampling technique, involving 124 subjects. Content validity was assessed through expert evaluation using the Content Validity Index (CVI), while construct validity was measured using Pearson Product-Moment Correlation. Reliability was evaluated through Cronbach’s Alpha to assess internal consistency. Results: The analysis revealed weak to moderate construct validity values (0.361–0.402) and excellent content validity index scores (S-CVI/Ave=1). Reliability analysis demonstrated good reliability with a Cronbach’s Alpha value of 0.725. Conclusion: The Indonesian version of the RMDQ questionnaire is valid and reliable for evaluating low back pain disability. It is suitable for use in clinical practice, enabling Indonesian patients to comprehend the questionnaire without losing the essence of the original version. Further research is needed to explore the onset and causes of low back pain disability in more depth.

Abstract

Introduction: Pencak silat is a traditional Indonesian martial art that has been an integral part of Indonesian culture for centuries. Among its various techniques, the T kick is known for its higher effectiveness compared to other kicks. To achieve a fast T kick, biomotor components such as flexibility and balance are essential. Methods: This observational analytic study employed a cross-sectional design. Subjects were selected through purposive sampling, consisting of male pencak silat athletes aged 15-18 years, with a total sample size of 116. The study included three variables: two independent variables (hamstring flexibility and balance) and one dependent variable (T kick speed). Data collection involved measuring hamstring flexibility, balance tests, and kick speed tests. The data were analyzed using the Spearman’s rho correlation test. The aim of this study was to determine the relationship between hamstring flexibility and balance with T kick speed in pencak silat athletes in Madiun City. Results: The non-parametric Spearman’s rho analysis showed a significant relationship between hamstring flexibility and T kick speed, with p=0.000 (p<0.05) and a correlation coefficient of 0.348. Additionally, a significant relationship was found between balance and T kick speed, with p=0.000 (p<0.05) and a correlation coefficient of 0.508. Conclusion: Based on these findings, it can be concluded that there is a relationship between hamstring flexibility and balance with T kick speed in pencak silat athletes in Madiun City.
