Background: Reliability refers to the precision of an assessment, so it is a critical topic to take the right decisions related to health management. People usually perform several tasks at the same time in their daily life. The aim of this study was to examine the reliability of the 30-s chair stand test in people with type 2 Diabetes Mellitus (T2DM) with test–retest, with and without dual-task (motor + cognitive task). Methods: Twenty-six subjects with T2DM and 30 subjects without T2DM performed the 30-s Chair Stand Test (30sCST) in which they must sit and stand as many times as possible in 30 s. They performed the test in the usual way (30sCST) and also with an additional cognitive task (30sCST-DT). A retest was conducted 7–14 days later. Results: Relative reliability was excellent in both groups (intraclass correlation coefficient > 0.9). In 30sCST-DT, relative reliability was high in the T2DM group (intraclass correlation coefficient > 0.7) and excellent in subjects without T2DM (intraclass correlation coefficient > 0.9). Conclusions: The 30sCST and the 30sCST-DT tests are reliable tools for people with T2DM to measure changes after an intervention. The smallest real difference was 15% and 20% upper in the T2DM group in the 30sCST and 30sCST-DT tests, respectively.

Background. Pathological activation of cytokines is one of the key links in the pathogenesis of diabetes mellitus (DM) and the development of its complications, in particular from the cardiovascular system. According to the vast majority of researchers, the imbalance of pro- and anti-inflammatory cytokines in patients with diabetes mellitus is a significant risk factor for mortality from cardiovascular disease. The purpose of the study was to determine the concentration of markers of a nonspecific inflammatory response (interleukin (IL) 6 and IL-10) in the blood of men with DM and their association with glycated hemoglobin levels and body mass index. Materials and methods. There were examined 46 men with type 2 DM and 28 men with type 1 DM. According to the results of the analysis of variance of the control group, type 2 DM and type 1 DM had significant differences in some indicators. Results. The correlation analysis of the obtained indicators of interleukin concentration showed that in men with type 2 DM under the age of 50 years, the indicators of IL-6 concentration significantly positively correlated with indicators of IL-10 concentration in blood (Spearman’s correlation coefficient 0.562, p < 0.031) and negatively with the duration of diabetes mellitus (Spearman’s correlation coefficient –0.508, p < 0.031). In the group of patients with type 2 DM aged 50 years and older, there was a positive correlation between the blood concentration of IL-6 with the blood concentration of IL-10 (Spearman’s correlation coefficient 0.509, p < 0.031), the blood concentration of IL-10 with glycated hemoglobin levels (Spearman’s correlation coefficient 0.391, p < 0.04) and the duration of diabetes mellitus (Spearman’s correlation coefficient 0.551, p < 0.005). In the group of patients with type 1 DM, there was a positive correlation of IL-6 in the blood with indicators of the blood concentration of IL-10 (Spearman’s correlation coefficient 0.707, p < 0.001) and a positive correlation between the concentration of IL-10 with the duration of DM (Spearman’s correlation coefficient 0.379, p < 0.039). Conclusions. Mean levels of IL-6 were significantly elevated in men with type 2 diabetes aged 50 years and older. Mean IL-10 levels were significantly elevated in men with type 2 diabetes regardless of the age of the patients. A significant positive correlation was found between the indicators of IL-6 and IL-10 in the examined patients with type 2 diabetes regardless of age also in patients with type 1 diabetes mellitus.

The present study aimed to: (1) analyze the test–retest reliability of the 30 s chair stand test and the 30 s arm curl test under dual-task conditions; (2) analyze the test–retest reliability of a new variable which assesses the total performance (cognitive + physical) in both tests. A total of 37 women with fibromyalgia participated in the study. Participants completed the 30 s arm curl test and 30 s chair stand test in both simple and dual-task conditions. These tests were repeated after seven days. In the 30 s chair stand dual-task test the reliability was low to good whereas that of the total performance variable was low to moderate. The reliability in both the 30 s arm curl dual-task test and the total performance variable were good to moderate. Both the 30 s chair stand test and 30 s arm curl test under dual-task conditions and the total performance variables had good test–retest reliability. However, it is necessary to consider the fluctuations of the intraclass correlation coefficient (ICC).

Test Retest Reliability

Background: Simple field tests such as the Timed Up and Go test (TUG) and 30 s Chair Stand test are commonly used to evaluate physical function in the elderly, providing crude outcome measures. Using an automatic chronometer, it is possible to obtain additional kinematic parameters that may lead to obtaining extra information and drawing further conclusions. However, there is a lack of studies that evaluate the test-retest reliability of these parameters, which may help to judge and interpret changes caused by an intervention or differences between populations. Thus, the aim of this study was to evaluate the test-retest reliability of the Timed Up and Go test (TUG) and 30 s Chair Stand test in healthy older adults. Methods: A total of 99 healthy older adults participated in this cross-sectional study. The TUG and the 30 s Chair Stand test were performed five times and twice, respectively, using an automatic chronometer. The sit-to-stand-to-sit cycle from the 30 s Chair Stand test was divided into two phases. Results: Overall, reliability for the 30 s Chair Stand test was good for almost each variable (intraclass correlation coefficient (ICC) >0.70). Furthermore, the use of an automatic chronometer improved the reliability for the TUG (ICC >0.86 for a manual chronometer and ICC >0.88 for an automatic chronometer). Conclusions: The TUG and the 30 s Chair Stand test are reliable in older adults. The use of an automatic chronometer in the TUG is strongly recommended as it increased the reliability of the test. This device enables researchers to obtain relevant and reliable data from the 30 s Chair Stand test, such as the duration of the sit-to-stand-to-sit cycles and phases.

Test Retest Reliability

BACKGROUND Performance tests are important to characterize patient disabilities and functional changes. The Osteoarthritis Research Society International and others recommend the 30-second Chair Stand Test and Stair Climb Test, among others, as core tests that capture two distinct types of disability during activities of daily living. However, these two tests are limited by current protocols of testing in clinics. There is a need for an alternative that allows remote testing of functional capabilities during these tests in the osteoarthritis patient population. OBJECTIVE Objectives are to (1) develop an app for testing the functionality of an iPhone’s accelerometer and gravity sensor and (2) conduct a pilot study objectively evaluating the criterion validity and test-retest reliability of outcome variables obtained from these sensors during the 30-second Chair Stand Test and Stair Climb Test. METHODS An iOS app was developed with data collection capabilities from the built-in iPhone accelerometer and gravity sensor tools and linked to Google Firebase. A total of 24 subjects performed the 30-second Chair Stand Test with an iPhone accelerometer collecting data and an external rater manually counting sit-to-stand repetitions. A total of 21 subjects performed the Stair Climb Test with an iPhone gravity sensor turned on and an external rater timing the duration of the test on a stopwatch. App data from Firebase were converted into graphical data and exported into MATLAB for data filtering. Multiple iterations of a data processing algorithm were used to increase robustness and accuracy. MATLAB-generated outcome variables were compared to the manually determined outcome variables of each test. Pearson’s correlation coefficients (PCCs), Bland-Altman plots, intraclass correlation coefficients (ICCs), standard errors of measurement, and repeatability coefficients were generated to evaluate criterion validity, agreement, and test-retest reliability of iPhone sensor data against gold-standard manual measurements. RESULTS App accelerometer data during the 30-second Chair Stand Test (PCC=.890) and gravity sensor data during the Stair Climb Test (PCC=.865) were highly correlated to gold-standard manual measurements. Greater than 95% of values on Bland-Altman plots comparing the manual data to the app data fell within the 95% limits of agreement. Strong intraclass correlation was found for trials of the 30-second Chair Stand Test (ICC=.968) and Stair Climb Test (ICC=.902). Standard errors of measurement for both tests were found to be within acceptable thresholds for MATLAB. Repeatability coefficients for the 30-second Chair Stand Test and Stair Climb Test were 0.629 and 1.20, respectively. CONCLUSIONS App-based performance testing of the 30-second Chair Stand Test and Stair Climb Test is valid and reliable, suggesting its applicability to future, larger-scale studies in the osteoarthritis patient population.

Background: Type 2 diabetes mellitus (T2DM) is a chronic, worldwide disease affecting more than 400 million people. This pathology involves several associated problems, such as diabetic neuropathy complications, obesity, and foot problems, both in terms of health and sensitivity. Objective: The objective of this study was to explore the relationships of the 30-s chair stand-up test with the Foot Health Status Questionnaire (FHSQ), the vibration perception threshold (VPT), and the 15-dimensional (15-D) questionnaire in T2DM people. Methodology: Ninety participants with T2DM were assessed in terms of fat mass percentage, VPT, foot health, health-related quality of life (HRQoL), and the 30-s chair stand-up test. Results: The 30-s chair stand-up test was found to exhibit a moderate relationship with “physical activity” (rho = 0.441; p ≤ 0.001) and “vigor” (rho = 0.443; p ≤ 0.001) from FHSQ. The 30-s chair stand-up test was also found to be weakly associated with foot pain (rho = 0.358; p = 0.001), 15-D total score (rho = 0.376; p ≤ 0.001), “sleeping” (rho = 0.371; p < 0.001), and “depression” (rho = 0.352; p = 0.001). Conclusions: The 30-s chair stand-up test is associated with “physical activity”, “vigor”, and “foot pain” from the FHSQ and the 15-D questionnaire total score and its dimensions “sleeping” and “depression” in type 2 diabetes mellitus patients. Therefore, following the results obtained, qualified clinicians can use the 30-s chair stand-up test as a good tool for monitoring and managing type 2 diabetes.

Background: India is one of the countries with highest number of diabetes patients. Patients of type 2 diabetes mellitus are usually dyslipidemic. The objective of the research was to study the pattern of dyslipidemia and to study the correlation of glycemic control with dyslipidemia in type 2 diabetes mellitus patients.Methods: A cross sectional observational study was performed on patients of type 2 diabetes mellitus over 6 months period. The study included 200 patients and the variables recorded were demographic profile, FBS, PPBS, HbA1C and lipid profile parameters. The patients were divided into 3 groups according to HbA1C level i.e. Group I (Good glycemic control HbA1C 6-7 gm%), group II (Fair glycemic control HbA1C 7.1-8.2 gm%) and group III (poor glycemic control, HbA1C >8.2 gm%).Results: The data showed that TG level was maximum in group III and was minimum in group I. Comparison between the group shows a significant difference between all the groups (P <0.001). A significant positive correlation (Correlation coefficient 0.67, P <0.001) was also observed between level of TG and HbA1C. Similarly, LDL level was also highest in group III with a significant difference with other two groups (P <0.05). Also, a positive correlation (Correlation coefficient 0.64, P <0.05) was observed between LDL and HbA1C. On the other hand, HDL was lowest in group III as compared to groups I and II (P <0.001) and a negative correlation (Correlation coefficient -0.716, P <0.001) was seen between HDL and HbA1C.Conclusions: Dyslipidemia is less prevalent in diabetics who have better glycemic control.

Introduction: Recent studies suggest that saliva could be functionally equivalent to serum in reflecting the physiological state of the body. Studies are being conducted to develop saliva as a tool for the screening and monitoring of chronic systemic diseases like Diabetes mellitus. Dyslipidaemia is most commonly assessed by laboratory lipid profile analysis in serum sample. This study is a step towards validation of saliva as a tool for the screening and monitoring of dyslipidaemia. Aim: To measure, compare and correlate the serum and salivary lipid profile parameters {Total Cholesterol (TC), High Density Lipoprotein (HDL) and Low Density Lipoprotein (LDL)} in Type 2 Diabetes mellitus patients and healthy individuals. Materials and Methods: The case control study was carried out for a period of one year i.e., from March 2019 to February 2020. The study comprised of 200 participants between the ages 31-70 years. The participants included 100 diabetic subjects with a history of diabetes for at least three years and 100 age matched subjects as controls. TC, HDL and LDL was estimated by using kits based on spectrophotometric principle. Statistical analysis was done on Statistical Package for Social Sciences (SPSS) Version 16.0. Mean, Standard deviation, Pearson’s correlation coefficient, along with regression analysis was carried out and compared between the groups. Results: There is a significant difference between the salivary TC, HDL and LDL levels in healthy individuals and diabetics. A strong and significant positive correlation of serum TC (Pearson correlation coefficient ‘r’=0.87 for controls, 0.66 for diabetics, p<0.01), HDL (Pearson correlation coefficient ‘r’=0.78 for controls, 0.88 for diabetics, p-value <0.01) and LDL (Pearson correlation coefficient ‘r’= 0.81 for controls, 0.87 for diabetics, p-value <0.01) levels with its respective salivary levels was obtained in all the participants (controls and diabetics) of the study. The regression coefficient was calculated and a formula was derived for prediction of serum lipid profile parameters using their respective salivary levels. Conclusion: Standardisation of the techniques for the estimation of salivary lipid profile parameters, including triglycerides and Very LDL (VLDL) and setting up a reference range will also make it useful in clinical practice.
