Abstract

Introduction: Knee osteoarthritis (OA) is a degenerative joint disease causing disability, especially in older adults. Flatfoot, marked by reduced medial arch height, alters lower limb biomechanics and may influence knee OA severity. Objective: To evaluate the association between foot arch, measured by Clarke’s angle, and knee OA severity based on the Kellgren-Lawrence (K-L) grading to provide clinical insight for guiding management decisions. Methods: A cross-sectional study of 57 knee OA patients at Siloam Karawaci Hospital was conducted. Clarke’s angle was measured using ink footprints, and K-L grading assessed radiological severity. Statistical tests included Kolmogorov-Smirnov, one-way ANOVA, and Kruskal-Wallis, with p < 0.05 considered significant. Results: Most participants were female (77.2%) with a mean age of 65.85 ± 9.69 years. OA severity was mostly mild to moderate (K-L 2 and 3). Flatfoot prevalence was 47.4%, and lower Clarke’s angles were significantly associated with higher K-L grades (p = 0.029). No significant differences in age or BMI were found across severity groups, though BMI trended higher with severity. Conclusion: Lower Clarke’s angle correlates with increased knee OA severity. Flatfoot may contribute to or result from OA progression. Further research is needed to clarify causation and inform management strategies.

Abstract

Background Piriformis syndrome (PS) is one causes of buttock and hip pain which is caused by pressure of sciatic nerves on piriformis muscle. PS is sometime misdiagnosed because of similar clinical signs and symptoms with other lower back pain diagnosis such as Hernia Nucleus Pulposus (HNP), Sacroiliac joint pain, facet joint pain. Gold standard diagnosis of PS is diagnostic block injection. However, provocative test and prolonged H reflex on EMG might be also standard diagnostic of PS.Aim Understand the sensitivity and specificity of provocative test and prolonged H reflex to diagnose PS.Method 72 patients with suspected PS who came to Neurology OPD in period of August- December 2017 were testing with physical examination (provocative test) and Electromyography test of H reflex. PS is diagnosed by positive diagnostic block injection. Data was proceeded with SPSS 20 version.Result 72 patients with buttock pain which diagnosed with PS were dominated by female gender than male with ratio 1:3 with housewives as majority of work. Most age groups were 48.6% elderly (age more than 60 years old). Provocative tests result of Freiberg, FAIR, Beatty, Pace Sign, Hip Abduction sensitivity were 52.30; 66.15; 53.84; 46.15; 55.32 and specificity were 100; 42.85; 71.42; 71.42; 57.14. While sensitivity and specificity of prolonged H reflex more than 1.86 msec were 69.23 and 28.59. Combination of 3 provocative tests (FAIR, Freiberg and Beatty) resulted highest sensitivity and specificity in this study as 71.42 and 100.Conclusion Provocative test and prolong H reflex can be supported diagnosis of PS. However both tests might not be comparable yet than diagnostic block injection as gold standard of PS. Combination of provocative test increased the sensitivity and specificity of provocative test than single test only.

Abstract

Background: Memory is a place where information is stored from the learning process or experience. There are several types of memory , one of them is short term memory. Declining sleep quality is directly proportional to the decrease in short-term memory. Poor sleep quality is often associated with medical student due to exams or vast amount of tasks. Therefore, researcher wants to see whether there is significant correlation between sleep quality and short-term memory function in students.Aim: To assess the association of the quality of sleep towards short term memory function of medical student of Pelita Harapan University.Methods: This study was conducted with a cross-sectional method, with taking sample using the method of a simple random sample. A total of 90 respondents at University of Pelita Harapan were taken. Data collected sorted out according to the inclusion and exclusion criteria. Quality of sleep assessed with PSQI questionnaire while short-term memory assessed by Digit span backward test. Results processed with SPSS version 24 and tested with Chi Square.Results: Data analyzed by Chi square test showed there are 33 students (58.9%) have poor sleep quality and short term memory function. There are also significant association between the quality of sleep and short term memory function (p value = 0.026)Conclusion: There is significant association between the quality of sleep and short term memory function of medical students of Pelita Harapan University.

Abstract

Background : Plantar fascia plays significant role in supporting the height and structure of Medial Longitudinal Arch (MLA). In flat foot, the MLA is depressed. There is thickening of plantar fascia reported in cases of plantar fasciitis in subjects with flat foot. Therefore, research needs to be done to investigate the relation between flat foot and plantar fascia thickness.Aim:  To understand the relationship between flat foot and plantar fascia thickness among medical students of Pelita Harapan University.Methods : This study was conducted using cross-sectional method with sampling method of non-random consecutive sampling. Data was collected through examinations performed and adjustments are made using inclusion and exclusion criteria. Flat foot was determined using navicular drop test and plantar fascia thickness was assessed using ultrasonography measurement. Results were analyzed using SPSS 22.0 and statistically tested using Spearman’s rho test.Result : The analysis of the relationship between flat foot and plantar fascia thickness showed positive correlation with correlation coefficient of 0.634 on the right foot and 0.443 on the left.Conclusion : There is moderate and strong positive relationship between flat foot and plantar fascia thickness among medical students of Pelita Harapan University.
