Reliability of 3D upper limb motion analysis in children with obstetric brachial plexus palsy

Abstract

Results indicated poor reliability for spatiotemporal parameters and range. Moderate to excellent reliability at PTA was observed in 19/60 variables (ICC: 0.77-0.98; SEM: 3.5°-10.4°). The Abduction Task had the highest (ICC: 0.79-0.98; SEM: 3.5°-10.3°) with External Rotation the lowest reliability. Glenohumeral and thoracohumeral elevation had the most consistent reliability. Scapular protraction/retraction had consistently poor reliability (ICC: 0-0.72; SEM: 3.5°-10.2°) with axial rotation also poor (ICC: 0.00-0.91; SEM: 6.3°-32.8°). This study determined inconsistent test-retest reliability of 3D-ULMA, using AM, to track dynamic performance of functional tasks in children with OBPP. It is the first study to outline measurement error in this population. This information permits more reliable interpretation of future studies of kinematic patterns in children with OBPP.

Three-dimensional kinematics of shoulder function in stroke patients: Inter- and intra-rater reliability

“…Several studies have reported reliability estimates of 3D kinematic measures of scapula positions and movements in healthy populations and people with shoulder impingement syndrome (Roy et al, 2007), children with cerebral paresis (Jaspers, Feys, Bruyninckx, Harlaar, et al, 2011;Lempereur et al, 2012;Mahon et al, 2017) and stroke patients using static (Pain et al, 2018) or dynamic assessments in shoulder flexion and abduction (De Baets, Jaspers, et al, 2013;De Baets, Van Deun, et al, 2013).…”

Validity and Reliability of Wearable Motion Sensors for Clinical Assessment of Shoulder Function in Brachial Plexus Birth Injury

“…That is, the shoulder joint rotates substantially under the skin without the sensor following along which leads to a larger error compared to the error that arises during flexion/abduction of the upper arm where the sensor smoothly follows the movement. Moreover, due to anatomical differences and contractures, BPBI patients tend to have less control over rotational movement [ 2 , 15 ], something that may have influenced the reliability of the outcome scores from the BPBI group.…”

“…To analyze test–retest and interrater reliability, the intraclass correlation coefficient (ICC) was calculated. For both test–retest and interrater reliability, an ICC value below 0.50 was considered as low reliability, ICC between 0.50 and 0.75 was considered moderate, ICC between 0.75 and 0.90 was defined as good reliability, and ICC > 0.90 as excellent reliability [ 15 , 38 ]. To analyze test–retest reliability, a mean value from the five trials from each occasion was used.…”

“…Visual grading based on the Active Movement Scale [ 10 ] and modified Mallet score [ 11 ] was developed to facilitate long-term follow-ups for range of motion and muscle function in BPBI patients and is used extensively throughout the world [ 5 ]. The scales are efficient and easy to implement in clinic but have been criticized as too subjective and missing crucial functional deficiencies [ 12 , 13 , 14 , 15 , 16 ]. Further, these scales do not describe how the glenohumeral joint and scapulothoracic articulation contribute to global shoulder (i.e., thoracohumeral) shoulder motion.…”
