OBJECTIVES: To determine the reliability of static scapular posture (SP), clavicular tilt angle (CTA) and the scapular dyskinesis (SD) assessments by expert and student therapists. DESIGN: inter-rater and intra-rater reliability study. SETTING: University level male rugby union club PARTICIPANTS: Four sport rehabilitation students and one experienced physiotherapist evaluated the position of the scapular and clavicle of male university-level rugby union players (inter-rater participants: session 1: n=17, session 2: n=12 and session 3: n=16; intra–rater participants: n = 12). MAIN OUTCOME MEASURESː Participants attended 3 testing sessions, each 1 week apart. Scapular orientation and motion were assessed in five planes of movement and using the Scapular Dyskinesis Test (SDT) respectively. RESULTSː Kappa coefficient values and percentage agreement ratings for students compared to the experienced therapist were: SP=poor to fair (-0.01-0.33), (27% - 94%); SDT=slight (0.16) (41%); CTA=fair (0.21) (59%). Test-retest (intra-rater) agreement was fair to moderate (0.22 – 0.44) (69% -95%), slight (0.12) (47%), and fair (0.39) (77%) for the SP, SDT, and CTA, respectively. CONCLUSIONSː Static and dynamic evaluation of the shoulder by students and an experienced therapist has poor to moderate reliability and should not be used to make clinical decisions based on observation alone.

AbstractObjectiveTo determine whether the literature filtering process, a vital initial component of a systematic literature review, could be successfully completed by nutrition professionals or non-professionals.DesignUsing a diet–disease relationship as the guideline topic, inter-rater agreement for the title and abstract filtering processes between and among professionals and non-professionals was assessed and compared with an expert reference standard. Predetermined eligibility criteria were applied by all raters to 185 titles and 90 abstracts. Filtering decisions were initially made independently and then revised after a within-pair consensus meeting.SubjectsThe raters were six dietitians (RD) and six nutrition graduate students (Grad). To assess inter-rater agreement (reliability), each group was divided into three pairs.ResultsWeighted and unweighted kappa statistics and percentage agreement were calculated to determine the inter-rater agreement within pairs. Sensitivity and specificity estimates were determined by comparing responses with those of an expert reference standard. Overall, Grad pairs demonstrated greater inter-rater agreement than RD pairs for title filtering (P < 0.05); no differences were observed for abstract filtering. Compared with the expert reference standard, every rater and pair had false-negative responses for both title and abstract filtering.ConclusionsAfter consensus meetings, both RDs and Grads were comparable in their agreement on title and abstract filtering, although important differences remained compared with the expert reference standard. This study provides preliminary findings on the value of utilising a non-expert pair in developing guidelines, and suggests that the literature filtering process is complex and quite subjective.

Background. Achieving reproducibility in research design is challenging when patient cohorts under study are inconsistently defined. Traditional Chinese medicine (TCM) diagnosis is one example where inconsistency between practitioners has been found. We hypothesise that the use of a validated instrument may improve consistency. Biochemical biomarkers may also be used enhance reliability.Methods. Twenty-seven participants with prediabetes were assessed by two TCM practitioners using a validated instrument (TEAMSI-TCM). Inter-rater reliability was summarised using percentage agreement and the kappa coefficient. One-way ANOVA and Tukey’s post hoc test were used to test links between TCM diagnosis and biomarkers.Results. The two practitioners agreed on primary diagnosis of 70% of participants. kappa = 0.56 (P<0.001). The three predominant TCM diagnostic patterns for people with prediabetes were Yin deficiency, Qi and Yin deficiency and Spleen qi deficiency. The Spleen Qi deficiency with Damp cohort had statistically significant higher fasting glucose, higher insulin, higher insulin resistance, higher HbA1c and lower HDL than those with Qi and Yin deficiency.Conclusions. Using the TEAMSI-TCM resulted in moderate interrater reliability between TCM practitioners. This study provides initial evidence of variation in the biomarkers of people with prediabetes according to the different TCM patterns which may suggest a route to further improving interrater reliability.

Abstract Background and Purpose. Previous research suggests that visual estimates of sacroiliac joint (SIJ) alignment are unreliable. The purpose of this study was to determine whether handheld calipers and an inclinometer could be used to obtain reliable measurements of SIJ alignment in subjects suspected of having SIJ dysfunction. Subjects. Seventy-three subjects, evaluated at 1 of 5 outpatient clinics, participated in the study. Methods. A total of 23 therapists, randomly paired for each subject, served as examiners. The angle of inclination of each innominate was measured while the subject was standing. The position of the innominates relative to each other was then derived. An intraclass correlation coefficient (ICC), the standard error of measurement (SEM), and a kappa coefficient were calculated to examine the reliability of the derived measurements. Results. The ICC was .27, the SEM was 5.4 degrees, and the kappa value was .18. Conclusion and Discussion. Measurements of SIJ alignment were unreliable. Therapists should consider procedures other than those that assess SIJ alignment when evaluating the SIJ.

ABSTRACT The aim was to describe trunk control in ambulant and non-ambulant patients with Duchenne muscular dystrophy (DMD). We conducted a cross-sectional analysis of a sample of 50 DMD patients, (M age = 16.7 years) who underwent the Segmental Assessment of Trunk Control (SATCo). A seven-level scale of trunk control was used (1: head control only; 7: control of entire trunk while unsupported). Static, active and reactive posture control were evaluated in ambulant and non-ambulant patients. Inter-rater reliability for all assessments was evaluated by calculating the kappa coefficient. More advanced disease (having higher Vignos scores), was associated with poorer trunk control. Ambulant patients showed better trunk control than non-ambulant patients (p = 0.003). There was strong inter-rater agreement for SATCo scale scores.

Abstract Background The reproducibility and reliability of the modified Rodnan’s Skin Score (mRSS) are debated due to investigator-related subjectivity. Here, we evaluate if durometry correlates with mRSS in patients with diffuse systemic sclerosis (SSc). Methods This cross-sectional study was conducted from December 2018 to June 2019, including 58 diffuse SSc patients. Two certified researchers, blind to each other’s scores, performed the mRSS, followed by durometry at 17 predefined skin sites. For durometry and mRSS, individual scores per skin site were registered. Durometry and mRSS results measured by each researcher, as well as scores from different researchers, were compared. Skin thickness measurements from forearm skin biopsies were available in a subset of the patients, for comparisons. Statistical analyses included Cohen’s Kappa Coefficient, Intraclass Correlation Coefficient, Kendall’s Coefficient and Spearman’s test. Results Mean (standard deviation, SD) patient age was 44.8 (12.9) years, and 88% were female. Inter-rater agreement varied from 0.88 to 0.99 (Intraclass correlation coefficient) for durometry, and 0.54 to 0.79 (Cohen’s Kappa coefficient) for mRSS, according to the specific evaluated sites. When data were compared with skin thickness assessed in forearm biopsies, durometry correlated better with skin thickness than mRSS. Conclusion Durometry may be considered as an alternative method to quantify skin involvement in patients with diffuse SSc. The strong inter-rater agreement suggests that the method may be useful for the assessment of patients by multiple researchers, as in clinical trials.
