Reliability of the Pediatric Specific Musculoskeletal Ultrasound Scoring Systems for the Elbow, Wrist, and Finger Joints.

ABSTRACT:

Objective

Musculoskeletal ultrasound (MSUS) is increasingly being used in the evaluation of pediatric musculoskeletal diseases. In order to provide objective assessments of arthritis, reliable MSUS scoring systems are needed. Recently, joint-specific scoring systems for arthritis of the pediatric elbow, wrist, and finger joints were proposed by the Childhood Arthritis and Rheumatology Research Alliance (CARRA) MSUS workgroup. This study aimed to assess the reliability of these scoring systems when used by sonographers with different levels of expertise.

Methods

Members of the CARRA MSUS workgroup attended training sessions for scoring the elbow, wrist, and finger. Subsequently, scoring exercises of B mode and power Doppler (PD) mode still images for each joint were performed. Interreader reliability was determined using 2-way single-score intraclass correlation coefficients (ICCs) for synovitis and Cohen [Formula: see text] for tenosynovitis.

Results

Seventeen pediatric rheumatologists with different levels of MSUS expertise (1-15 yrs) completed a 2-hour training session and calibration exercise for each joint. Excellent reliability (ICC > 0.75) was found after the first scoring exercise for all the finger and elbow views evaluated on B mode and PD mode, and for all of the wrist views on B mode. After a second training session and a scoring exercise, the wrist PD mode views reached excellent reliability as well.

Conclusion

The preliminary CARRA MSUS scoring systems for assessing arthritis of the pediatric elbow, wrist, and finger joints demonstrate excellent reliability among pediatric MSUS sonographers with different levels of expertise. With further validation, this reliable joint-specific scoring system could serve as a clinical tool and scientific outcome measure.

Project description:BackgroundElbow and wrist chronic conditions are very common among musculoskeletal problems. These painful conditions affect muscle function, which ultimately leads to a decrease in the joint's Range Of Motion (ROM). Due to their portability and ease of use, goniometers are still the most widespread tool for measuring ROM. Inertial sensors are emerging as a digital, low-cost and accurate alternative. However, whereas inertial sensors are commonly used in research studies, due to the lack of information about their validity and reliability, they are not widely used in the clinical practice. The goal of this study is to assess the validity and intra-inter-rater reliability of inertial sensors for measuring active ROM of the elbow and wrist.Materials and methodsMeasures were taken simultaneously with inertial sensors (Werium™ system) and a universal goniometer. The process involved two physiotherapists ("rater A" and "rater B") and an engineer responsible for the technical issues. Twenty-nine asymptomatic subjects were assessed individually in two sessions separated by 48 h. The procedure was repeated by rater A followed by rater B with random order. Three repetitions of each active movement (elbow flexion, pronation, and supination; and wrist flexion, extension, radial deviation and ulnar deviation) were executed starting from the neutral position until the ROM end-feel; that is, until ROM reached its maximum due to be stopped by the anatomy. The coefficient of determination (r 2) and the Intraclass Correlation Coefficient (ICC) were calculated to assess the intra-rater and inter-rater reliability. The Standard Error of the Measurement and the Minimum Detectable Change and a Bland-Altman plots were also calculated.ResultsSimilar ROM values when measured with both instruments were obtained for the elbow (maximum difference of 3° for all the movements) and wrist (maximum difference of 1° for all the movements). These values were within the normal range when compared to literature studies. The concurrent validity analysis for all the movements yielded ICC values ≥0.78 for the elbow and ≥0.95 for the wrist. Concerning reliability, the ICC values denoted a high reliability of inertial sensors for all the different movements. In the case of the elbow, intra-rater and inter-rater reliability ICC values range from 0.83 to 0.96 and from 0.94 to 0.97, respectively. Intra-rater analysis of the wrist yielded ICC values between 0.81 and 0.93, while the ICC values for the inter-rater analysis range from 0.93 to 0.99.ConclusionsInertial sensors are a valid and reliable tool for measuring elbow and wrist active ROM. Particularly noteworthy is their high inter-rater reliability, often questioned in measurement tools. The lowest reliability is observed in elbow prono-supination, probably due to skin artifacts. Based on these results and their advantages, inertial sensors can be considered a valid assessment tool for wrist and elbow ROM.

Project description:This article was updated on May 4, 2017, because of a previous error. The proximal line drawn in Figure 1 was different from the line described in the Materials and Methods section, which reads "The proximal line was drawn at the level of the radial tuberosity, and the distal line was made at the level of the top of the radial bowing (Fig. 1)." The correct figure is presented in this version of the article. An erratum has been published: JBJS Open Access. 2017 May 26;2(2):e0012ER.BackgroundWe conducted a retrospective cohort study to evaluate the normal value, range, reliability, and validity of measurement of the humerus-elbow-wrist angle, an index of valgus-varus angulation of the elbow, in healthy children. This measurement has been used to assess postoperative radiographic results.MethodsRadiographs of the elbow in 62 healthy children ranging from 2 to 11 years of age were reviewed by 6 examiners at 2 sessions. The mean value and the reliability of measurement of the humerus-elbow-wrist angle, the carrying angle, and the Baumann angle were assessed. Intraobserver and interobserver reliability were calculated with use of intraclass correlation coefficients (ICCs). To determine concurrent validity, the association between the humerus-elbow-wrist angle and carrying angle measurements was examined with use of Pearson correlation coefficients.ResultsThe mean humerus-elbow-wrist angle value was 12.0° (range, 1° to 24°), and the mean carrying angle was 14.6° (range, 4° to 28°). The ICCs for intraobserver measurements of the humerus-elbow-wrist angle were almost perfect for 4 examiners and were substantial for 2 examiners, with a mean value of 0.85 (range, 0.73 to 0.94). The ICCs for interobserver reliability with regard to the first and second measurements of the humerus-elbow-wrist angle were both substantial (0.76 and 0.78). A significant association between the humerus-elbow-wrist angle and the carrying angle was observed, with the Pearson correlation coefficients ranging from 0.74 to 0.90 (p < 0.001).ConclusionsMeasurement of the humerus-elbow-wrist angle demonstrated good reliability and validity. The humerus-elbow-wrist angle is a reliable radiographic measure of coronal alignment of the humerus and forearm.

Project description:BackgroundSeveral radiographic measurements of the humerus can be used to evaluate the treatment outcome of supracondylar fractures in children. Because of the cartilaginous nature of the immature elbow, interpretation of radiographs around this area is sometimes challenging and can be unreliable. This study was conducted to determine the inter-observer and intra-observer reliability of the six commonly used radiographic measurements of the distal humerus.MethodThe Baumann angle, humero-ulna angle, metaphyseal-diaphyseal angle, radial epiphyseal angle, shaft-condylar angle and lateral capitellohumeral angle of the humerus were measured by two observers on the radiographs of uninjured elbows from 58 children. The values between each measurement were compared and correlated using a Pearson coefficient of correlation to determine the inter-observer and intra-observer reliability.ResultsAll of the radiographic parameters showed excellent intra-observer reliability with the correlation coefficient values of the Baumann angle, humero-ulna angle, metaphyseal-diaphyseal angle, radial epiphyseal angle, shaft-condylar angle, lateral capitellohumeral angle as 0.945, 0.95, 0.909, 0.888, 0.961 and 0.975 (p < 0.001), respectively. The inter-observer reliability of the Baumann and humero-ulna angles were also found to be highly correlated at r = 0.843 (p < 0.001) and 0.878 (p < 0.001), respectively. The metaphyseal-diaphyseal angle had poor reliability with r = 0.136 (p = 0.291) while the radial epiphyseal angle, shaft-condylar angle, and lateral capitellohumeral angle demonstrated good reliability with r = 0.675 (p < 0.001), 0.747 (p < 0.001), and 0.686 (p < 0.001), respectively.ConclusionThe Baumann angle and humero-ulna angle measurements of distal humerus showed excellent inter- and intra-observer reliability. Both parameters represent repeatable and reliable methods for determining the outcome of supracondylar humeral fractures in pediatric population.
