The subtalar calcaneal angle: A novel angle for evaluation of displaced calcaneal fractures – A retrospective study

ObjectivesThe radiological measurement of the Böhler angle (BA) and the critical angle of Gissane (CAG) is used not only to diagnose and corroborate the suspicion of the presence of calcaneal fractures but also to assess the prognosis of different injury patterns and to evaluate the operative reduction of calcaneal fractures. Notwithstanding, many previous studies indicated the poor intra- and interobserver reproducibility of both angles. In this retrospective study, we present the subtalar calcaneal angle (SCA) as an additional diagnostic tool -to BA and CAG-which can be applied on pre- and postoperative radiographs to assess calcaneal fractures involving the posterior facet. DesignRetrospective Study. MethodsTwo retrospective groups were established, a ‘CF-group’ including radiographs of patients diagnosed with a calcaneal fracture and underwent operative treatment in the authors' traumatology department, and a ‘control group’ with 50 lateral calcaneal radiographs clear of skeletal lesions. Initially, the SCA, BA, and CAG were measured in both groups by three examiners. Those measurements were repeated one month later. The intra- and intertester reliabilities of all three angles were tested by determining the intraclass correlation coefficient (ICC). A paired t-test was used to prove the statistically significant difference between the SCA values for the pre- and postoperative groups, while the significant difference between the SCA values for the control and preoperative groups was tested through an independent-samples t-test. ResultsThe intra- and interobserver reliability of the SCA and the BA was in close proximity. The values of the SCA in both the control and postoperative groups were significantly different compared to the measurements of the preoperative group. The CAG showed poor intertester reliability. ConclusionThe subtalar calcaneal angle is a new instrument with proven reliability in estimating the prognosis of displaced calcaneal fractures and the postoperative alignment of the posterior facet. Level of clinical evidenceDiagnostic, Level III.

Well-being evocative places: validating the conceptual model of an evocative place based on the inter-rater reliability test

ABSTRACT An evocative place is defined as a place that evokes emotions, memories and images. Well-being evocative places are places that enable people to recharge and feel at peace. Data about well-being evocative places and their descriptions was collected in a series of mapping experiments in Hamburg (Germany), Ames (Iowa), and Vitória (Brazil). The Conceptual Model of an Evocative Place (CMEP) was designed based on the collected data in these three cities. It conceptualizes descriptions of evocative places as expressed in words by the participants. The model stresses the value of tangible and intangible attributes of evocative places described by their characteristics, experience, senses and values. The main goal of this article is to present the CMEP and the methodology for its validation accomplished with the help of a new set of data collected in the cities of Vienna (Austria) and Grinnell (Iowa). The inter-rater reliability (IRR) test provided a framework for its validation. Two raters used newly collected data and the categories proposed in the CMEP. The content analysis and the calculated IRR served as the basis for the changes and improvements of the CMEP. The article concludes with a discussion of the main results and future research directions.

Inter-tester and intra-tester reliability of physical examination test used to measure positional faults of the shoulder girdle in healthy individuals

Introduction Sustained, repetitive, prehensile activities that require precision and stability, necessitate a sustained static shoulder girdle posture over long periods of time, which can result in abnormal activation of the shoulder girdle musculature and consequent scapular misalignments. Aim, Aim of this study was to establish test-retest and inter-tester reliability of six (6) clinical tests commonly used to measure parameters related to shoulder girdle positional faults and or asymmetries. Material and Methods A convenience sample of 100 healthy 18–25-year-old, male college students were evaluated on the following tests: Pectoralis minor index, Lateral scapular slide test, Posterior capsular tightness, Forward shoulder posture, cervical range of motion, and shoulder muscle Isometric strength. Result Intra-class correlations (ICC) were calculated across trials (test-retest) and across testers (inter-rater) in a repeated measure ANOVA.Test-retest ICC for forward shoulder posture (0.998), Cervical range of motion (0.987 to 0.999), Isometric shoulder strength (0.986-0.997), Pectoralis minor index (0.982 to 0.984), Lateral scapular slide test (0.997- 0.969) and Posterior Capsular Tightness (0.967 to 0.974) was found to be excellent but Inter-rater and reliability values were in the poor to moderate ranges.

Inter-rater and Intra-Rater Reliability Test with Goodenough-Harris Drawing Test

Introduction:There are various methods to measure intelligence in children, one of them is by drawing method. Goodenough-Harris Drawing Test (GHDT) is the first cognitive measurement tool developed based on drawing. Giving quantitative scores in drawing methods has been a challenging task, especially in controlling the level of subjectivity. It requires psychometric reliability evidence to make sure the result is free from bias.Methods:Drawings of 799 children (kindegarten/4 to 6 y.o= 412, primary school/7 to 9 y.o= 387 ; boys= 388, girls= 411) were examined to investigate inter-rater and intra-rater reliability in GHDT scoring. Data are scored by two raters who have been given special training on the scoring system based on the manual book. Pearson correlation is used to analyzed drawing reliability.Results:Significant correlation between the scores of two rates were 0.840 (p<.001) for the man drawing, and 0.844 (p<.001) for the woman drawing. In addition, intra-rater reliability ranged from 0.880 to 0.963.Conclusion:The study showed that GHDT has a high-reliability score by raters who trained based on a manual book GHDT scoring system. In addition, these results also showed scoring criteria were applied consistently.

An evaluation of temporal and club angle parameters during golf swings using low cost video analyses packages

The purpose of this study was to compare swing time and golf club angle parameters during golf swings using three, two dimensional (2D) low cost, Augmented-Video-based-Portable-Systems (AVPS) (Kinovea, SiliconCoach Pro, SiliconCoach Live). Twelve right-handed golfers performed three golf swings whilst being recorded by a high-speed 2D video camera. Footage was then analysed using AVPS-software and the results compared using both descriptive and inferential statistics. There were no significant differences for swing time and the golf phase measurements between the 2D and 3D software comparisons. In general, the results showed a high Intra class Correlation Coefficient (ICC > 0.929) and Cronbach’s Coefficient Alpha (CCA > 0.924) reliability for both the kinematic and temporal parameters. The inter-rater reliability test for the swing time and kinematic golf phase measurements on average were strong. Irrespective of the AVPS software investigated, the cost effective AVPS can produce reliable output measures that benefit golf analyses.

Assessing the Content Validity of the Revised Health of the Nation Outcome Scales (HoNOS 2018).

The Health of the Nation Outcome Scales (HoNOS) comprises 12 scales that cover the kinds of problems that may be experienced by working-age adults in contact with specialised mental health services. Drawing on 20 years’ experience in clinical practice, a collaborative, international review of the HoNOS was undertaken and a revised measure (known as the HoNOS 2018) was published. In this study, 32 experts from Australia, England and New Zealand completed an anonymous web-based survey to assess the relevance, comprehensiveness and comprehensibility (aspects of content validity) of the HoNOS 2018. The experts rated 11 of the 12 HoNOS 2018 scales as ‘important’ or ‘very important’ for determining the overall clinical severity (item-level content validity index or I-CVI ≥ 0.75). Evaluations of the scales’ ability to capture change, comprehensiveness and comprehensibility were more variable, but generally positive. Experts’ comments provided further insights into this variability; for example, they noted that some scales combine multiple phenomena, which can result in ambiguity in item wording and assessment challenges. Results from this study suggest that the revisions have not altered the importance of the scales. Given the measure’s breadth of content, training remains important for ensuring rating fidelity. Inter-rater reliability and utility testing are indicated.

Algorithmic Assessments in Deciding on Voluntary, Assisted or Involuntary Psychiatric Treatment.

The challenges in assessing whether psychiatric treatment should be provided on voluntary, assisted or involuntary legal bases prompted the development of an assessment algorithm that may aid clinicians. It comprises a part that assesses the incapacity to provide informed consent to treatment, care or rehabilitation. It also captures the patient’s willingness to receive these treatments, the risk posed to the patient’s health or safety, financial interests or reputation and risks of serious harm to self or others. By following various decision paths, the algorithm yields one of four legal states: a voluntary, assisted, or involuntary state or that the proposed intervention should be declined. This study examined the predictive validity and the reliability of this algorithm. It was applied 4052 times to 135 clinical case narratives by 294 research participants. The legal states yielded by the algorithm had high statistical significance when matched with the gold standard (Chi-squared = 6963; df = 12; p < 0.001). It was accurate in yielding the correct legal state for the voluntary, assisted, involuntary and decline categories in 94%, 92%, 88% and 86% of the clinical case narratives, respectively. For internal reliability, a correspondence model accounted for 99.8% of the variance by which the decision paths clustered together fittingly with each of the legal states. Inter-rater reliability testing showed a moderate degree of agreement among participants on the suitable legal state (Krippendorff’s alpha = 0.66). These results suggest the algorithm is valid and reliable, which warrant a subsequent randomised controlled study to investigate whether it is more effective in clinical practice than standard assessments.

The Timed Water Swallow Test (TWST): Normative data on swallowing capacity for healthy people aged 60 years and older

Purpose To provide normative data on swallowing capacity (mL/s) in people older than 60 years using the Timed Water Swallow Test (TWST), stratified by sex. Intra- and inter-rater reliability for swallowing time in TWST was further investigated. Method A total of 165 participants, aged 60 years and above, were included in the study. The time taken to consume 150 mL of tap water and the swallowing capacity (mL/s) was observed in a clinical context using the TWST. Video recordings of the performances were collected for 118 of the 165 participants for inter-rater reliability testing, of which a random set of 25 performances were assessed for intra-rater reliability. Analysis of the agreement between TWST rated by an in-person clinician and rated from a video recording was further evaluated. Result There were significant age and sex effects observed for swallowing capacity. The average reduction in swallowing capacity in the investigated age range (60–92 years) was 8.8 and 7.3 mL/s, for women and men respectively. The results showed high inter-and intra-rater reliability and agreement between the clinical assessment and the video recording. Conclusion The presented measurements indicate a clear effect of age on swallowing capacity and that women may be expected to have lower capacity scores than men when tested using TWST. The provided norms can be used as reference points in the clinical identification of people at risk of dysphagia in the older population.

Quantifying the stiffness of lumbar erector spinae during different positions among participants with chronic low back pain.

ObjectiveThe purposes of this study were to (1) detect the intra- and inter-reliabilities of the lumbar erector spinae stiffness by MyotonPRO among participants with chronic lower back pain (CLBP); (2) compare the muscle stiffness between pain and non-pain sides during different positions; (3) explore the correlation between intensity of pain and muscle stiffness.DesignTwenty participants with CLBP were recruited and the stiffness measurements were carried out by two experienced physiotherapists (operators Ⅰ and Ⅱ). Each participant was evaluated by the operatorⅠ in different postures (static prone and sitting). After a 5-day interval, the same participant was reassessed by the operatorⅠ in the static prone posture. For the inter-rater reliability test, each participant was quantified by both operators once, with 30 minutes between the measurements on the same day. The intensity of pain was evaluated using a 0–10 visual analog scale (VAS).ResultsThe intra- and inter-rater reliabilities were excellent (ICC = 0.88–0.99). The MDC values ranged from 25.03 to 86.26 N/m. Examples of Bland-Altman plots showed good agreement. The erector spinae stiffness on the painful sides was higher with a marked increase in the sitting position (P < .05) when compared with the non-painful side. However, there was no significant difference in the prone position (P > .05). The intensity of pain among adults with CLBP was not associated with muscle stiffness of the lumbar erector spinae muscle.ConclusionsOur findings indicated that the MyotonPRO is a feasible device in quantifying the stiffness of the lumbar erector spinae muscle in patients with CLBP. Meanwhile, the erector spinae stiffness on the painful sides was higher in the sitting when compared with the non-painful side.

Developing Student Creative Problem-Solving Skills (CPSS) Using Online Digital Storytelling

This study set out to research and evaluate the needs in developing creative problem-solving skills (CPSS) of undergraduate students through developing and evaluating a digital storytelling process using Padlet. The sampling process used simple random sampling to select 332 teachers from 83 schools in Bangkok. The data was collected using a needs assessment questionnaire, training course questionnaire, and satisfaction questionnaire. Descriptive statistics used for the analysis included frequency, percentage, mean ( , and standard deviation (SD). The data collected were mean scores of expert validity testing and student inter-rater reliability testing. The assessment evaluated student satisfaction toward the CPSS training course using 30 students in the Computer Education Program at Dhonburi Rajabhat University's Faculty of Education in Thailand. The findings revealed that of the four aspects identified for developing undergraduate CPSS, elaboration was at the top of the priority of needs (PNIModified = 0.20). This was followed by originality and flexibility (PNIModified = 0.19). Finally, was fluency (PNIModified = 0.18). Also, analysis of the prospective condition was ranked ‘high’ across all four aspects with an average of = 4.38 SD = 0.06. Further analysis of the real condition showed that all four aspects had an average of = 3.67, SD = 0.06. The study contributes to the literature in that it demonstrated that correctly developed and implemented undergraduate student CPSS can increase significantly. This fact is critical in knowing as a nation’s future depends on its workforce and leaders having CPSS.

Reliability and Validity of the ActivForce Digital Dynamometer in Assessing Shoulder Muscle Force across Different User Experience Levels.

BackgroundCurrently available hand-held dynamometers (HHD) offer a more objective and reliable assessment of muscle force production as compared to a manual muscle test (MMT). Yet, their clinical utility is limited due to high cost. The ActivForce (AF) digital dynamometer is a new low-cost HHD with unknown psychometric properties, and its utilization may benefit clinical practice.Hypothesis/PurposeThis study aimed to determine the AF intra- and inter-tester reliabilities, standard error of measurement (SEM), minimal detectable change (MDC), and criterion validity for assessing shoulder isometric force as compared to the microFET2 (MF2) across testers with different experiences.DesignDescriptive observational study.MethodsA convenience sample of 29 healthy adults were assessed twice by each of three testers (two experienced clinicians and a novice PT student) on shoulder external rotation (ER), internal rotation (IR), and forward elevation (FE) using both the AF and MF2 devices. Tester, HHD, and shoulder motion assignment orders were randomized. All testing was performed in a standardized seated position. ER and IR were tested with the shoulder fully adducted. FE was tested at 45° at the scapular plane. All testing and rest periods between testers and tested motions were standardized and monitored via a stopwatch.ResultsBoth devices had high intra- [ ER (.95-.98), IR (.97 - .99), FE (.96 - .99)] and inter-tester [ ER (.85-.96), IR (.95 - .97), FE (.88 - .95)] intraclass correlation coefficient (ICC) with comparable intra- (1.68-1.80) and inter-tester (2.36-2.98) SEM, and intra- (4.64-4.97) and inter-tester (6.50-8.24) MDC values across all motions. Tester experience did not affect these values. High (.89-.93) statistically significant Pearson correlations were found between HHDs for all shoulder motions.ConclusionBoth the AF and MF2 HHDs were found to have high reliability levels across all shoulder motions regardless of tester clinical experience. The AF was also found to be valid for measuring shoulder isometric force production compared to the criterion standard device, the MF2. Its low-cost and electronic accessibility features may promote better compliance for clinicians using dynamometry to objectively assess and store muscle force data in a cost-effective manner.Level of Evidence3

Intra-Rater and Inter-Rater Reliability of Muscle Length Test for Extensor Digitorum Longus

Background A short extensor digitorum longus (EDL) is associated with limited ankle dorsiflexion, toe deformities (such as hammer toe and claw toe), and diabetic plantar ulcers. Therefore, measurement of EDL is important for the evaluation of patients with foot dysfunction. Purpose The aim of this study was to evaluate the intra- and inter-rater reliability of the muscle length test for EDL. Study design Repeated measures for intra- and inter-test reliability. Methods Thirty participants were recruited. Two physical therapists evaluated EDL length based on the difference in passive ankle plantar flexion angle between relaxed and flexed toe positions. Each examiner measured it in each participant three times. The intraclass correlation coefficient was used to assess the intra- and inter-rater reliability of the muscle length test for EDL. Results The intra- and inter-rater reliability values were 0.83 and 0.75, respectively. The standard error of measurement was 1.93° and the minimum detectable change was 5.35°. Conclusions The muscle length test is a reliable method for measuring EDL length in clinical practice.

Media coverage of Canadian Veterans, with a focus on post traumatic stress disorder and suicide

BackgroundA large corpus of research indicates that the media plays a key role in shaping public beliefs, opinions and attitudes towards social groups. Some research from the United States indicates that military Veterans are sometimes framed in a stereotypical and stigmatizing manner, however there is a lack of research on Canadian media coverage of Veterans. As such, the overarching aim of this study is to assess the tone and content of Canadian media coverage of military Veterans, with a focus on PTSD and suicide. The first objective is to document and analyze common themes, content and temporal patterns in Canadian media coverage of Veterans per se. The second objective is to examine common themes and content in the sub-set of articles having PTSD as a theme. The third objective is to assess adherence to responsible reporting of suicide guidelines in the sub-set of articles having suicide as a theme.MethodsWe used validated and systematic methods including use of key words, retrieval software and inter-rater reliability tests to collect and code news articles (N = 915) about Veterans from over 50 media sources during a 12-month period, with specific coding of articles about PTSD (N = 93) and suicide (N = 61).ResultsAnalysis revealed that the most common theme is ‘honour or commemoration of Veterans’ which occurred in over half of the articles. In contrast 14% of articles focused on danger, violence or criminality. In the sub-set of articles with PTSD as a theme, over 60% focused on danger, violence or criminality, while only around 1 in 3 focused on recovery, rehabilitation, or health/social service intervention. In the sub-set of articles about suicide, there was generally strong adherence to responsible reporting guidelines, though less than 5% gave help-seeking information. Moreover, most reporting on PTSD and suicide focused on a single anomalous murder-suicide incident, with few articles about suicide prevention, helpful resources and modifiable risk factors.ConclusionsThe results reveal some encouraging findings as well as a need to diversify media coverage of Canadian Veterans. This could be achieved through targeted educational outreach to help Canadian journalists responsibly report on Veterans and their mental health issues.

The development of a clinical screening tool to evaluate unilateral landing performance in a healthy population

ObjectivesTo develop a clinical tool to evaluate unilateral landing quality in a healthy population. The reliability of the novel tool was evaluated, and the influence of gender and leg-dominance was investigated. DesignAn experimental study for developing a test protocol, scoring criteria, and scoring method, based on observable landing errors, for the novel Unilateral Landing Error Scoring System (ULESS). SettingControlled lab environment. ParticipantsHealthy participants (25♂ and 25♀) performed the ULESS. Main outcome measuresThe ULESS was scored with video analysis. Unilateral landing performance, measured with the ULESS, was compared to bilateral landing performance. ResultsSixteen items to assess trunk, pelvic, and lower limb movement patterns during a unilateral landing task resulted in a composite score on an interval scale. Moderate to excellent intra- and inter-tester reliability (ICC(2,1) = 0.77–0.90) was determined. The ULESS was able to identify moderate to poor unilateral landing quality in subjects with good to excellent bilateral landing quality. No main effect of gender (p = 0.19) or leg-dominance (p = 0.65) on ULESS scores was found. ConclusionModerate to excellent reliability can be expected when using the newly developed protocol and scoring method. The ULESS is feasible to perform with limited materials.

The DoCTRINE Guidelines: Defined Criteria To Report INnovations in Education.

Reporting guidelines assist authors in conducting and describing their research in alignment with evidence-based and expert-determined standards. However, published research-oriented guidelines do not capture all of the components that must be present in descriptions of educational innovations in health professions education. The authors aimed to create guidelines for educational innovations in curriculum development that would be easy for early-career educators to use, support reporting necessary details, and promote educational scholarship. Beginning in 2017, the authors systematically developed a reporting checklist for educational innovations in curriculum development, called Defined Criteria To Report INnovations in Education (DoCTRINE), and collected validity evidence for its use according to the 4 inferences of Kane's framework. They derived the items using a modified Delphi method, followed by pilot testing, cognitive interviewing, and interrater reliability testing. In May-November 2019, they implemented DoCTRINE for authors submitting to MedEdPORTAL, half of whom were randomized to receive the checklist (intervention group). The authors scored manuscripts using DoCTRINE while blinded to group assignment, and they collected data on final editorial decisions. The final DoCTRINE checklist consists of 19 items, categorized into 5 components: introduction, curriculum development, curriculum implementation, results, and discussion. The overall interrater agreement was 0.91. Among the 108 manuscripts submitted to MedEdPORTAL during the study period, the mean (SD) total score was higher for accepted than rejected submissions (16.9 [1.73] vs 15.7 [2.24], P = .006). There were no significant differences in DoCTRINE scores between the intervention group, who received the checklist, and the control group, who did not. The authors developed DoCTRINE, using systematic approaches, for the scholarly reporting of educational innovations in curriculum development. This checklist may be a useful tool for supporting the publishing efforts of early-career faculty.

The effect of extraction of the lower first permanent molar on the developing third molar in children

To find the effect of extraction of the lower first permanent molar in children (aged 8-11 years) on the position and angle of the developing third molar. Retrospective radiographic analysis. Two cohorts of participants were identified: an extraction group, who had extraction of one or more first permanent molars aged 8-11 years; and a non-extraction group, who retained all mandibular teeth. Both cohorts previously had panoramic radiographs taken at mean ages of 9.7 years (T1), before extraction, and 12.12 years (T2). In total, there were 61 third molars with an associated extracted first permanent molar and 60 third molars with an associated retained first permanent molar. A digital radiographic analysis was carried out on the panoramic radiographs to measure the movement of the third molar, vertically and horizontally, and its angle. The magnification of the T1 and T2 radiographs was calibrated. Reliability of the radiographic analysis was confirmed via intra- and inter-rater reliability tests. The extraction and non-extraction groups were compared via independent sample tests. The third molar moved significantly more mesial in the extraction group (P < 0.001) and the angle uprighted significantly more than the non-extraction group (P < 0.001). Vertically, the third molar moved inferiorly in both cohorts with no significant difference. In the developing dentition, extraction of the lower first permanent molar encouraged mesial movement and uprighting of the developing third molar. This may improve the likelihood of future eruption of the third molar.

The Effects of Active Range of Motion on Upper Trapezius’ Fasciae Displacement among Individuals with and without Myofascial Pain Syndrome

Aim: This study determined the differences in upper trapezius' superficial and deep fascia slides among MPS and non-MPS participants after performing cervical active range of motion (AROM). The association between the fascia slides, age, sex, occupation, clinical diagnosis, and symptoms’ chronicity were determined. Methods: This retrospective study constituted a reliability and case-control study. Three hundred participants (174 MPS: 126 non-MPS) were included. For each fascia level, six physiotherapy interns read 19 MSUS videos. Bland Altman Plot and Single Measures Intraclass Correlation Coefficient (ICC) determined the physiotherapy interns' intratester and intertester reliability. Twelve physiotherapy interns quantified the fascia slides in 3,600 MSUS videos. MPS and non-MPS groups were compared against differences in fascia slides using independent samples t-test. A p-value of &lt;0.05 indicated significant differences in fascia slides. Multiple regression analyses determined fascia slides and independent variables’ relationship. Results: Intertester reliability in tracking the superficial and deep fasciae was very good (ICC = 0.90 to 1.00). Intratester reliability showed minimal to no individual bias (95% CI). A significant difference in superficial fascia displacement between groups was only observed during active cervical extension (p&lt; 0.05). No difference in cervical AROM was reported in deep fascia displacement between groups (p&gt; 0.05). No associations were found between superficial fascia slides and independent variables (p &gt;0.05). Sex was the only variable associated with deep fascia slide difference (p &lt;0.05). Conclusion and Implications: Limited fascia slide is not a characteristic of individuals with MPS. There is no association between differences in fascia slides and independent variables.
