The Verbal Numerical Rating Scale and Faces Pain Scale-Revised for Children With Acute Pain: A Comparative Study for Determining the Need for Analgesia.

Introduction The primary complaint in all age groups of patients, including children, is pain, which drives the patient to the hospital. A good assessment of pain severity is necessary to determine the right therapy for this primary complaint. Pain scales, especially in children, are given little importance in all hospitals in India. We need more data about its effectiveness. As a result, we conducted this study to compare the effectiveness of two pain scales in an admitted patient. Methods An observational study was conducted on pediatric patients aged 8-17 admitted to a tertiary care unit in pediatric wards included in the study. The study team identified the participants with painful and nonpainful conditions by asking patients of the above age group if they had "any pain" or "any hurt." The verbal numerical rating scale (vNRS) was determined by asking, "On a scale of zero to 10, where zero signifies no pain and ten means severe pain." The child was advised to select from among the six faces using the faces pain scale-revised (FPS-R), showing increasing levels of pain intensity (from left to right), with score options 0, 2, 4, 6, 8, and 10 demonstrated below each face. Result We enrolled 140 children, of which 22 of vNRS and 15 of FPS-R were removed from the study as these children did not understand vNRS and FPS-R. The two-tailed t-test revealed that the p-value was 0.9144. By conventional criteria, in the context of statistical analysis, conventional criteria typically refer to commonly accepted thresholds for determining statistical significance. The most common threshold for significance is a p-value of 0.05 or less. In the provided scenario, the two-tailed t-test resulted in a p-value of 0.9144. By conventional criteria (i.e., using the threshold of 0.05), this p-value is considered not significant. This means that there is not enough evidence to reject the null hypothesis, which suggests that there is no significant difference between the two groups being compared (in this case, the efficacy and reliability of the two scales). Therefore, based on conventional criteria, the difference in efficacy and reliability between the two scales is considered not significant, indicating that they are likely to be equally effective and reliable. This difference is considered not significant. Hence, it is suggestive of equal efficacy and reliability on both scales.  Conclusion Pain scales are a practical guide for managing and recognizing pain in children. It needs to be considered in identifying children's pain. They can provide a valuable outcome for measuring pain, which, when practiced regularly, can save time and extra burden on health staff. In the present study, both pain scales (vNRS and FPR-R) have equal efficacy.

Reliability and validity of the Chinese revised version of the pectus excavatum evaluation questionnaire in children with pectus excavatum.

OBJECTIVE: This study aims to translate the Pectus Excavatum Evaluation Questionnaire(PEEQ) into Chinese, and to comprehensively assess subjective outcomes in quality of life of children with pectus excavatum. METHODS: The PEEQ was translated from English to Chinese as according to the PRO translation guidelines. Structural validity and reliability of the questionnaire were examined by validated factor analysis and Cronbach's alpha coefficient analysis respectively. RESULTS: The results of the validation factor analysis for the Chinese PEEQ parent's and child's questionnaires demonstrated that the fit indicators for each dimension met the required criteria. The overall Cronbach's alpha coefficient of parent's and child's questionnaires were 0.840 and 0.854. Both the item-level content validity index (I-CVI) and scale-level content validity index (S-CVI) of each sub-questionnaire were 1. CONCLUSION: The Chinese version of the PEEQ parent's questionnaire is suitable as a proxy assessment for patients with PE, but the child's questionnaire needs further adjustments.

Development, Reliability and Validity of the Medication Literacy Scale for Parents of Children with Epilepsy.

Purpose: This study aimed to develop a medication literacy scale for parents of children with epilepsy (MLSPCE) and to test the reliability and validity of the scale. Patients and Methods: The pilot scale was formulated based on the concept of medication literacy, the knowledge-attitude-practice model, and relevant literature reviews. It was formed through two rounds of expert consultations using the Delphi method. A survey of 657 parents of children with epilepsy, who were admitted to the neurology department or examined in the neuro-electrophysiological outpatient department of Guangzhou Women and Children Medical Center, using the pilot scale was conducted from October 2021 to January 2022 to test the reliability and validity of the scale questionnaire. The content validity of the scale questionnaire was assessed by consulting 20 neurology nursing, neurology clinician, and nursing education experts. Numbers, percentages, t-test, correlation analysis, Cronbach's alpha reliability coefficient and factor analysis were used for data analysis. Results: The MLSPCE included 34 items in four dimensions. Ten factors were drawn from the explorative factor analysis, with a cumulative variance contribution rate of 62.32%. The content validity index of each item on the 34-item scale was between 0.81 and 1.0, and the scale-content validity index/ average was 0.97. The correlation coefficient between each item and its dimension was between 0.399 and 0.760, the correlation coefficients between dimensions were between 0.150 and 0.382, and the correlation coefficients between each dimension and the total scale were between 0.390 and 0.845. Differences for all comparisons were statistically significant (P < 0.05). Cronbach's alpha coefficient for the total scale was 0.864, and the split-half reliability of the total scale was 0.923. Conclusion: All the statistical procedures performed in the validity and reliability stages of the study showed that MLSPCE is a valid and reliable tool for measuring medication literacy among Chinese parents of children with epilepsy.

Reliability of the DSS-Swe Questionnaire.

BACKGROUND: Symptomatic postbariatric hypoglycemia (PBH) is a known complication that can occur a few years after Roux-en-Y gastric bypass (RYGB). There is currently no established rating scale for PBH-associated symptoms developed for use in Swedish populations. The aim of the study was to translate an already existing questionnaire into Swedish and to test its reliability. METHODS: The study included forward and backward translations of the original Dumping Severity Scale (DSS) questionnaire with 8 items regarding symptoms of early dumping and 6 items regarding hypoglycemia, with each item graded on a 4-point Likert scale. The reliability of the Swedish translated questionnaire (DSS-Swe) was estimated using internal consistency and test-retest methods. RESULTS: A total of 200 patients were included in the study. Good internal consistency was demonstrated regarding the items related to early dumping symptoms, with a Cronbach's alpha coefficient of 0.82, and very good agreement in terms of test-retest reliability, with an overall intraclass correlation coefficient (ICC) of 0.91 (95% CI 0.88-0.93). The items related to hypoglycemia yielded a good Cronbach's alpha coefficient of 0.76 and an ICC of 0.89 (95% CI 0.85-0.91). CONCLUSION: The DSS-Swe questionnaire shows good reliability regarding both internal consistency and test-retest performance for use in Swedish populations.

Indonesian Translation and Cross-Cultural Validation of Pediatric Anesthesia Parent Satisfaction (PAPS) Questionnaire.

BACKGROUND: Many questionnaires have been widely used to assess patient satisfaction. One of them is the Pediatric Anesthesia Parent Satisfaction (PAPS) questionnaire. However, in Indonesia, the parent satisfaction of pediatric patients undergoing surgery has never been studied. Knowing patient satisfaction can provide feedback to improve the quality of anesthesia services. Furthermore, the PAPS questionnaire has never been used in Indonesia, so it needs to be translated and tested for validity and reliability before being implemented in Indonesia. AIM: to validate the Indonesian version of the PAPS questionnaire Method: This study uses a descriptive-analytic method with a cross-sectional design. The PAPS Questionnaire was translated into Indonesian version with the following steps (1) forward translation, (2) establish an expert committee, and (3) backward translation. After that, pilot testing and FGD with the expert were conducted to obtain the final questionnaire. Pearson's correlation and confirmatory factor analysis (CFA) were employed for the validity test. Sampling measurement before CFA was carried out with Keyser-Meyer-Olkin (KMO) and Bartlett's test. Cronbach's alpha determined the reliability test evaluation. RESULT: Total number of subjects is 125 subjects. The PAPS questionnaire in the Indonesian version was obtained with help from INCULS and an anesthesiologist expert. Pearson's correlation found that all items ranged from r = 0.531-0.796 with p < 0.001. The CFA showed two factors that explained 65% of the total variance, with KMO being 0.937 (X2=1283.452, p < 0.001). Cronbach's alpha coefficient was 0.937. CONCLUSION: Indonesian version of the PAPS questionnaire is valid and reliable for assessing parents' satisfaction with the anesthesia services their child received.

Diagnostic Accuracy and Agreement Between Inter- and Intra-Observers in the Absence of Clinical History for Liquid-Based Preparation of Gynecology Specimens.

Context: The clinical history in cytology is the best source of information to ensure the accuracy of diagnosis, facilitating a slide observer to interpret and relate their findings in screening gynecology slides. Aims: This study aims to evaluate the performance of slide observers to screen-blinded gynecology slides without providing any information on clinical history. Setting and Design: A correlational study design was conducted at the cytology laboratory, Universiti Teknologi MARA Selangor, Puncak Alam Campus. Methods and Materials: Fity-seven liquid-based preparation slides from gynecology specimens were screened blindly by five slide observers among Medical Laboratory Technology students who completed the enrollment of the cytology course. Statistical Analysis Used: The inter- and intra-observer reliability testing was measured using the kappa value of Fleiss' and Cohen's kappa value, respectively, while the diagnostic accuracy without a clinical history was determined by the receiver operating characteristic (ROC) curve. Results: The value of Fleiss' kappa (κ) was 0.221-this represents a fair strength of agreement between inter-observers. An intra-observer reliability test for each slide observer was analyzed using Cohen's kappa statistic and revealed that the kappa value varied between 0.116 and 0.696, indicating slight-to-substantial agreement between intra-observers. Additionally, the sensitivity value of 94.28%, specificity value of 72.40%, a positive predictive value (PPV) of 37.28%, a negative predictive value (NPV) of 72.40%, a likelihood ratio of 14.43, and the diagnostic accuracy of 75.09% were recorded. Conclusions: In conclusion, the students (slide observers) from the Centre of Medical Laboratory Technology Studies who took part in this study were able to interpret, classify, and diagnose the LBP gynecologic cytopathological cases into several categories (NILM and ECA) based on the 2001 Bethesda System reporting guideline.

Reliability Study of the Items of the Alberta Infant Motor Scale (AIMS) Using Kappa Analysis.

PURPOSE: We evaluated the interrater and intrarater reliabilities of the Korean version of the Alberta Infant Motor Scale (K-AIMS). METHODS: For the interrater reliability test, six raters participated in the K-AIMS evaluation using video clips of 70 infants (aged between 0 and 18 months). One rater participated in an intrarater reliability test. Among 70 infants, 46 were born preterm and 24 were born full term. A total of 58 AIMS items were evaluated for supine, prone, sitting, and standing positions. A reliability analysis was conducted using ICC and Fleiss' kappa. RESULTS: The highest Fleiss' kappa was found for the 4-7 months group for sitting (K = 0.701-1.000) and standing (K = 0.721-1.000), while the lowest K was the 3 months or under group for standing (K = 0.153-1.000). We found higher Fleiss' kappa statistics when all infants were evaluated without grouping for the three positions (K = 0.727-1.000), except standing (K = 0.192-1.000), for the interrater analysis. CONCLUSION: Our results demonstrate the good reliability for the Korean version of the AIMS for Korean infants (preterm and full term).

A Microtester for Measuring the Reliability of Microdevices in Controlled Environmental Conditions.

A miniaturized reliability test system for microdevices with controlled environmental parameters is presented. The system is capable of measuring key electrical parameters of the microdevices while controlling the environmental conditions around the microdevices. The test system is compact and thus can be integrated with standard test equipment for microdevices. By using a feed-forward decoupling algorithm, the presented test system is capable of generating a temperature range of 0-120 °C and a humidity range of 20-90% RH (0-55 °C), within a small footprint and weight. The accuracy for temperature and humidity control is ±0.1 °C and ±1% RH (30 °C), respectively. The functionality of the proposed test system is verified by integrating it with a piezo shaker to test the environmental reliability of an electromagnetic vibration energy harvester. The proposed system can be used as a proof-of-technology platform for characterizing the performance of microdevices with controlled environmental parameters.

Based on the relationship between failure characteristics and clinical application data, a complete set of closed-loop implementation methods from reliability index requirements to reliability design and verification are discussed.

Recovering Reliable Idiographic Biological Parameters from Noisy Behavioral Data: the Case of Basal Ganglia Indices in the Probabilistic Selection Task.

Behavioral data, despite being a common index of cognitive activity, is under scrutiny for having poor reliability as a result of noise or lacking replications of reliable effects. Here, we argue that cognitive modeling can be used to enhance the test-retest reliability of the behavioral measures by recovering individual-level parameters from behavioral data. We tested this empirically with the Probabilistic Stimulus Selection (PSS) task, which is used to measure a participant's sensitivity to positive or negative reinforcement. An analysis of 400,000 simulations from an Adaptive Control of Thought-Rational (ACT-R) model of this task showed that the poor reliability of the task is due to the instability of the end-estimates: because of the way the task works, the same participants might sometimes end up having apparently opposite scores. To recover the underlying interpretable parameters and enhance reliability, we used a Bayesian Maximum A Posteriori (MAP) procedure. We were able to obtain reliable parameters across sessions (intraclass correlation coefficient ≈ 0.5). A follow-up study on a modified version of the task also found the same pattern of results, with very poor test-retest reliability in behavior but moderate reliability in recovered parameters (intraclass correlation coefficient ≈ 0.4). Collectively, these results imply that this approach can further be used to provide superior measures in terms of reliability, and bring greater insights into individual differences.

New Classification and Its Value Evaluation for Atlantoaxial Dislocation.

OBJECTIVE: To introduce the TOI classification system (the Traction reduction type [T type], Operation reduction type [O type], and Irreducible type [I type] classification system) and to determine the interobserver and intraobserver reliability of the TOI classification system. METHODS: Based on the characteristics of atlantoaxial dislocation (AAD), AAD was divided into Traction reduction type (T type), Operation reduction type (O type), and Irreducible type (I type). The analysis of interobserver and intraobserver agreements was done using kappa statistics. From July 2016 to January 2019, 213 AAD patients were retrospectively studied at four hospitals. Plain radiographs including extension and flexion views and three-dimensional CT images were obtained. Twenty independent observers, including eight experienced spine specialists and 12 orthopaedic fellows from four different residency training hospitals, completed the survey. RESULTS: The classification of the TOI system was based on etiology, the course of the disease, flexion-extension X-rays, three-dimensional CT reconstruction, and curative effects of skull traction. Flexion-extension X-rays demonstrating a successful reduction of the dislocated atlantoaxial joint and three-dimensional CT images showing osseous fusion of atlantoaxial facet joints and cervical traction reveal characteristics of T-type. Furthermore, this type can be divided into two subtypes, T1 and T2, according to the etiology and course of the disease. Unsatisfactorily reduction after 1-2 weeks of strict cervical traction, no reduction shown on flexion-extension X-rays, and no destruction or boneless fusion of atlantoaxial facet joints demonstrated in three-dimensional CT images are characteristics of type O. Atlantoaxial facet joint showing bone fusion or failure of reduction after cervical traction or three-dimensional CT images showing failure of surgical release are characteristics of type I. Interobserver and intraobserver reliability of the TOI classification system were moderate (κ = 0.543) and substantial (κ = 0.658), respectively. Interobserver and intraobserver reliability of the treatment choice were moderate (κ = 0.568) and substantial (κ = 0.675), respectively. There were no significant differences in the interobserver and intraobserver reliability between experienced spine specialists and fellows for all κ-values (P > 0.05). CONCLUSIONS: The TOI classification system had satisfactory reliability and, therefore, can be applied clinically and used by less experienced surgeons. We believe TOI can help surgeons choose appropriate treatment strategies.

Investigation of Electrical Properties and Reliability of GaN-Based Micro-LEDs.

In this paper, we report high-performance Micro-LEDs on sapphire substrates, with pixel size scaling to 20 µm and an ultra-high current density of 9902 A/cm2. The forward voltages (VF) of the devices ranged from 2.32 V to 2.39 V under an injection current density of 10 A/cm2. The size and structure-dependent effects were subsequently investigated to optimize the device design. The reliability of Micro-LED devices was evaluated under long-aging, high-temperature, and high-humidity conditions. It was found that Micro-LED devices can maintain comparable performance with an emission wavelength of about 445 nm and a full width at half maximum (FWHM) of 22 nm under extreme environments. Following this, specific analysis with four detailed factors of forward voltage, forward current, slope, and leakage current was carried out in order to show the influence of the different environments on different aspects of the devices.

Development and Validation of a Questionnaire on Consumer Psychological Capital in Food Safety Social Co-governance.

Consumers play an important role as one of the main actors in food safety social co-governance. To create a pattern of food safety social co-governance, the active and effective participation of consumers is critical. To encourage consumers to participate in food safety social co-governance voluntarily and positively, we attempted to develop and preliminarily validate a multidimensional questionnaire on consumer psychological capital that could be used to measure the degree of consumer participation in food safety social co-governance. The aim of the initial sample (N = 170) and test sample 2 (N = 204) was to investigate the factor structure of a preliminary measure of consumer psychological capital. A 4-factor model with 23 items explained 61.05% of the total variance in item scores. The aim of test sample 3 (N = 30) was to measure the retest reliability. Test sample 4 (N = 1,076) was randomly allocated to the modeling sample (N = 538) and validation sample (N = 538) to verify questionnaire reliability and validity. Convergent validity, discriminant validity, and the internal inconsistency coefficients of the questionnaire were assessed in the modeling sample. While processing CFA, we deleted 9 items with small standardized factor loadings. The remaining 14 items in the final revised 4-factor model included self-efficacy, resilience, hope, and optimism. The fit indices of the revised four-factor model and second-order factor model in the modeling sample revealed an acceptable model fit. The convergent validity and discriminant validity of the revised model were good and acceptable, respectively. A cross-validation procedure confirmed the appropriateness of the revised four-factor model and second-order factor model in the validation sample. The cross-validation results confirmed that the fit indices of the revised four-factor model fitted the data well and the second-order factor model in the validation sample reached acceptable values. We concluded that the questionnaire developed in this study had good reliability and stable and acceptable construct validity. It could provide a theoretical basis for measuring psychological capital in food safety co-governance.

Accelerated Reliability Growth Test for Magnetic Resonance Imaging System Using Time-of-Flight Three-Dimensional Pulse Sequence.

A magnetic resonance imaging (MRI) system is a complex, high cost, and long-life product. It is a widely known fact that performing a system reliability test of a MRI system during the development phase is a challenging task. The major challenges include sample size, high test cost, and long test duration. This paper introduces a novel approach to perform a MRI system reliability test in a reasonably acceptable time with one sample size. Our approach is based on an accelerated reliability growth test, which consists of test cycle made of a very high-energy time-of-flight three-dimensional (TOF3D) pulse sequence representing an actual hospital usage scenario. First, we construct a nominal day usage scenario based on actual data collected from an MRI system used inside the hospital. Then, we calculate the life-time stress based on a usage scenario. Finally, we develop an accelerated reliability growth test cycle based on a TOF3D pulse sequence that exerts highest vibration energy on the gradient coil and MRI system. We use a vibration energy model to map the life-time stress and reduce the test duration from 537 to 55 days. We use a Crow AMSAA plot to demonstrate that system design reaches its useful life after crossing the infant mortality phase.

A Comparison of 3 Quantitative Radiographic Measurement Methods for Root Development Measurement in Regenerative Endodontic Procedures.

INTRODUCTION: The outcomes of an immature tooth with necrotic pulp treated with regenerative endodontic procedures (REPs) were assessed clinically and radiographically. Root maturation is an important outcome of REPs, and several radiographic measurement methods have been used to measure this. The aim of this study was to compare radiographic measurement methods, measuring root maturation in immature teeth with necrotic pulp treated with REPs. METHODS: Seventy-one radiographic images of REP cases were measured and compared using 3 radiographic measurement methods described by Bose et al (2009), Alobaid et al (2014), and Flake et al (2014). The intraclass correlation coefficient values were evaluated using the intra- and interobserver reliability test and the effect of the stage of root development. RESULTS: The intra- and interobserver reliability for Alobaid et al's method and Flake et al's method were slightly higher than Bose et al's method as quantified by the intraclass correlation coefficient without a significant difference (P > .05). The stage of root development did not affect the reliability of the measurement methods. A high level of agreement was found among the 3 stages of root development for all 3 quantitative radiographic measurement methods. CONCLUSIONS: All 3 quantitative radiographic measurement methods exhibited high agreement regarding reliability. The stage of root development did not have an impact on the reliability of the measurement methods.

Accurate FDG PET tumor segmentation using the peritumoral halo layer method: a study in patients with esophageal squamous cell carcinoma.

BACKGROUND: In a previous study, FDG PET tumor segmentation (SegPHL) using the peritumoral halo layer (PHL) was more reliable than fixed threshold methods in patients with thyroid cancer. We performed this study to validate the reliability and accuracy of the PHL method in patients with esophageal squamous cell carcinomas (ESCCs), which can be larger and more heterogeneous than thyroid cancers. METHODS: A total of 121 ESCC patients (FDG avid = 85 (70.2%); FDG non-avid = 36 (29.8%)) were enrolled in this study. In FDG avid ESCCs, metabolic tumor length (ML) using SegPHL (MLPHL), fixed SUV 2.5 threshold (ML2.5), and fixed 40% of maximum SUV (SUVmax) (ML40%) were measured. Regression and Bland-Altman analyses were performed to evaluate associations between ML, endoscopic tumor length (EL), and pathologic tumor length (PL). A comparison test was performed to evaluate the absolute difference between ML and PL. Correlation with tumor threshold determined by the PHL method (PHL tumor threshold) and SUVmax was evaluated. RESULTS: MLPHL, ML2.5, and ML40% correlated well with EL (R2 = 0.6464, 0.5789, 0.3321, respectively; p < 0.001) and PL (R2 = 0.8778, 0.8365, 0.6266, respectively; p < 0.001). However, ML2.5 and ML40% showed significant proportional error with regard to PL; there was no significant error between MLPHL and PL. MLPHL showed the smallest standard deviation on Bland-Altman analyses. The absolute differences between ML and PL were significantly smaller for MLPHL and ML40% than for ML2.5 (p < 0.0001). The PHL tumor threshold showed an inverse correlation with SUVmax (σ = - 0.923, p < 0.0001). CONCLUSIONS: SegPHL was more accurate than fixed threshold methods in ESCC. The PHL tumor threshold was adjusted according to SUVmax of ESCC.

Is the two-dimensional computed tomography scan analysis reliable for coracoid graft positioning in Latarjet procedures?

BACKGROUND: The aim of the study was to develop a computed tomography (CT)-based measurement protocol for coracoid graft (CG) placement in both axial and sagittal planes after a Latarjet procedure and to test its intraobserver and interobserver reliability. METHODS: Fifteen postoperative CT scans were included to assess the intraobserver and interobserver reproducibility of a standardized protocol among 3 senior and 3 junior shoulder surgeons. The evaluation sequence included CG positioning, its contact area with the glenoid, and the angle of its screws in the axial plane. The percentage of CG positioned under the glenoid equator was also analyzed in the sagittal plane. The intraobserver and interobserver agreement was measured by the intraclass correlation coefficient (ICC), and the values were interpreted according to the Landis and Koch classification. RESULTS: The ICC was substantial to almost perfect for intraobserver agreement and fair to almost perfect for interobserver agreement in measuring the angle of screws in the axial plane. The intraobserver agreement was slight to almost perfect and the interobserver agreement slight to substantial regarding CG positioning in the same plane. The intraobserver agreement and interobserver agreement were both fair to almost perfect concerning the contact area. The ICC was moderate to almost perfect for intraobserver agreement and slight to almost perfect for interobserver agreement in analyzing the percentage of CG under the glenoid equator. CONCLUSION: The variability of ICC values observed implies that caution should be taken in interpreting results regarding the CG position on 2-dimensional CT scans. This discrepancy is mainly explained by the difficulty in orienting the glenoid in the sagittal plane before any other parameter is measured.

Development and Validation of a Questionnaire to Assess Knowledge, Threat and Coping Appraisal, and Intention to Practice Healthy Behaviors Related to Non-Communicable Diseases in the Thai Population.

Non-communicable diseases (NCDs) are important issues in Thailand and health sectors are now focusing on modifiable risks that include cognitive, affective and behavioral factors. This study aimed to develop and validate a questionnaire to assess knowledge about NCDs, threat appraisal, coping appraisal and intention to practice based on protection motivation theory. Content validity was determined by the mean of the item content validity index (I-CVI) from five experts. The questionnaire was pilot tested for difficulty of knowledge items and reliability test using the Kuder-Richardson (KR)-20 and Cronbach's alpha coefficient among 30 Thai adult subjects in the health office for two sub-districts. The mean I-CVI ranged from 0.90-1.00 and difficulty of knowledge ranged from 0.3-0.9. The reliability test of knowledge by KR-20 ranged from 0.648-0.799, while Cronbach's alpha coefficients of threat and coping appraisal and intention to practice ranged from 0.70-0.843. We compared sociodemographic data, knowledge about NCDs, threat appraisal, coping appraisal and intention to practice between 50 diabetic type 2 cases and 50 controls. T2DM cases had higher age, knowledge scores on diabetes and hypertension, threat appraisal scores on hypertension and cardiovascular disease when compared with control (p < 0.05). The questionnaire was valid and sufficiently reliable to use for data collection.

Shoulder and elbow kinematics during the Mallet score in obstetrical brachial plexus palsy.

BACKGROUND: The physical signs of obstetrical brachial plexus palsy range from temporary upper-limb dysfunction to a lifelong impairment and deformity in one arm. The aim of this study was to analyze the kinematics of the upper limb and to evaluate the contribution of glenohumeral and scapulothoracic joints of obstetrical brachial plexus palsy children. METHODS: Six children participated in this study: 2 males and 4 females with a mean age of 11.7years. Three patients had a C5, C6 lesion and 3 had a C5, C6, C7 lesion. They were asked to perform five tasks based on the Mallet scale and the kinematic data were collected using the Fastrak electromagnetic tracking device. FINDINGS: The scapulothoracic protraction and posterior tilt were significantly increased in the involved limb during the hand to mouth task (p=0.006 and p=0.015 respectively). The scapulothoracic Protraction/glenohumeral Elevation ratio was significantly increased in the involved limb during the hand to neck task (p=0.041) and the elevation task (p=0.015). The ratios of scapulothoracic Tilt on the three glenohumeral excursion angles were significantly increased during the hand to mouth task (p≤0.041). The scapulothoracic Mediolateral/glenohumeral Elevation ratio was significantly increased in the involved limb during the elevation task (p=0.038). The glenohumeral elevation excursion was significantly decreased in the involved limb during the hand to neck task (p<0.001) and the elevation task (p=0.0003). INTERPRETATION: This study gives us information about the greater contribution of the scapulothoracic joint to shoulder motion for affected arm of obstetrical brachial plexus palsy patients compared to their unaffected arm. Kinematic analysis could be useful in shoulder motion evaluation during the Mallet score and to evaluate outcomes after surgery.
