TL;DR: The Korean version of the Tinetti mobility test showed excellent validity and reliability for gait and balance and had high sensitivity and specificity for predicting falls among patients with Parkinson’s disease.
Abstract: Objective Postural instability and gait disturbance are the cardinal symptoms associated with falling among patients with Parkinson's disease (PD). The Tinetti mobility test (TMT) is a well-established measurement tool used to predict falls among elderly people. However, the TMT has not been established or widely used among PD patients in Korea. The purpose of this study was to evaluate the reliability and validity of the Korean version of the TMT for PD patients. Methods Twenty-four patients diagnosed with PD were enrolled in this study. For the interrater reliability test, thirteen clinicians scored the TMT after watching a video clip. We also used the test-retest method to determine intrarater reliability. For concurrent validation, the unified Parkinson's disease rating scale, Hoehn and Yahr staging, Berg Balance Scale, Timed-Up and Go test, 10-m walk test, and gait analysis by three-dimensional motion capture were also used. We analyzed receiver operating characteristic curve to predict falling. Results The interrater reliability and intrarater reliability of the Korean Tinetti balance scale were 0.97 and 0.98, respectively. The interrater reliability and intra-rater reliability of the Korean Tinetti gait scale were 0.94 and 0.96, respectively. The Korean TMT scores were significantly correlated with the other clinical scales and three-dimensional motion capture. The cutoff values for predicting falling were 14 points (balance subscale) and 10 points (gait subscale). Conclusion We found that the Korean version of the TMT showed excellent validity and reliability for gait and balance and had high sensitivity and specificity for predicting falls among patients with PD.

TL;DR: MBI has good validity and reliability as well as sensitivity in assessment of ADL of Chinese stroke patients and was more sensitive than BI in majorities of its items and its total scores as well.
Abstract: Objective To study the validity,reliability and sensitivity of the simplified Chinese version of modified Barthel index (MBI) in evaluation of activities of daily living(ADL) of Chinese stroke patients. Methods Forty Chinese stroke patients (26 males and 14 females,aged 59.65±11.68 years) participated in the study.The duration of the disease averaged 21.20±19.44 days.All the patients were evaluated for three times with MBI.Barthel Index (BI) and the motor component of Functional Independence Measure (M-FIM)independently by twophysiatrists.Spearman correlation coefficients between MBI and Barthel index (BI),between MBI and M-FIM were used to test the validity of MBI.Intraclass correlation coefficients (ICC) were used to test both interrater and intra rater reliability of MBI.Sensitivity of MBl was analyzed with the Wilcoxon signed rank test and paired t-test.Results MBI was highly correlated with BI in each item and total score(r=0.816~1.000,P<0.01),and with M-FIM in total score(r=0.935~0.981,P<0.01).There were high reliability with MBI in the results collected by same assessor and different assessors(ICC=0.866~0.997).Furthermore,MBI was more sensitive than BI in majorities of its items and its total scores as well.Conclusions MBI has good validity and reliability as well as sensitivity in assessment of ADL of Chinese stroke patients.

TL;DR: In this study, the medical record review for detecting adverse events showed intermediate to good level of inter-rater and intra- rater reliability.
Abstract: Objectives The purpose of this study was to assess the inter-rater reliability and intra-rater reliability of medical record review for the detection of hospital adverse events. Methods We conducted two stages retrospective medical records review of a random sample of 96 patients from one acute-care general hospital. The first stage was an explicit patient record review by two nurses to detect the presence of 41 screening criteria (SC). The second stage was an implicit structured review by two physicians to identify the occurrence of adverse events from the positive cases on the SC. The inter-rater reliability of two nurses and that of two physicians were assessed. The intra-rater reliability was also evaluated by using test-retest method at approximately two weeks later. Results In 84.2% of the patient medical records, the nurses agreed as to the necessity for the second stage review (kappa, 0.68; 95% confidence interval [CI], 0.54 to 0.83). In 93.0% of the patient medical records screened by nurses, the physicians agreed about the absence or presence of adverse events (kappa, 0.71; 95% CI, 0.44 to 0.97). When assessing intra-rater reliability, the kappa indices of two nurses were 0.54 (95% CI, 0.31 to 0.77) and 0.67 (95% CI, 0.47 to 0.87), whereas those of two physicians were 0.87 (95% CI, 0.62 to 1.00) and 0.37 (95% CI, -0.16 to 0.89). Conclusions In this study, the medical record review for detecting adverse events showed intermediate to good level of inter-rater and intra-rater reliability. Well organized training program for reviewers and clearly defining SC are required to get more reliable results in the hospital adverse event study.

TL;DR: Consistent outcomes between raters and by individual raters at different time points confirm the reliability of the décolleté grading scales, indicating that they will be a valuable tool for use in clinical research and practice.
Abstract: Background Decollete aging includes skin dyspigmentation, laxity, and visible wrinkling. The development of globally accepted scales for the assessment of decollete aging is essential for aesthetic research and patient evaluation. Objective To develop a set of grading scales for the objective assessment of decollete aging criteria and establish the reliability and validity of these scales. Materials and methods To describe age-related changes to the decollete, 3 photonumeric grading scales were created and validated: decollete wrinkles-at rest, decollete wrinkles-dynamic, and decollete pigmentation-at rest. Thirteen aesthetic experts rated photographs of the decollete of 50 women at rest and at dynamic "hand-to-elbow" positions in 2 validation sessions. Responses were analyzed to assess interrater and intrarater reliability. Results Interrater and intrarater reliability were both "almost perfect" (≥0.81, intraclass correlation coefficient and weighted kappa) for decollete wrinkles-dynamic, summary score for decollete, and estimated age. Reliability was "substantial" (0.61-0.80) for all other decollete assessments. There was high correlation between all decollete scales, estimated age, and estimated aesthetic treatment effort. Conclusion Consistent outcomes between raters and by individual raters at different time points confirm the reliability of the decollete grading scales, indicating that they will be a valuable tool for use in clinical research and practice.
