“…reachable workspace) and can differentiate glenohumeral and scapulothoracic joint motion. 4,5 Motion analysis yields a more accurate and nuanced assessment of shoulder function than can be obtained from a Mallet score. 5 Infants are followed up on a monthly basis to track their progress and to determine the necessity of microsurgical intervention.…”

The care of children with brachial plexus birth injuries (BPBI) is a complex multidisciplinary endeavor. At the Shriners Hospital for Children in Philadelphia, we have sought to elevate the quality of care delivered to patients through outcomes research and collaboration with colleagues around the world. Our approach to the management of this challenging pathology has evolved time and again. Here, we describe our current approach to patient assessment and operative management in patients with BPBI and its many sequelae.

“…Such methods have been used to identify deficient external rotation in the glenohumeral joint and the global movement of the shoulder in children with BPBI when performing tasks of the modified Mallet scale [ 12 , 24 ]. Further, a recent study evaluated a clinical tool that incorporates real-time visual feedback with three-dimensional optical motion capture to measure and analyze shoulder function in BPBI patients [ 25 ]. Optical motion capture, a gold standard technique, requires special movement laboratories [ 26 ], which makes it unsuitable for regular assessments of shoulder function.…”

The modified Mallet scale (MMS) is commonly used to grade shoulder function in brachial plexus birth injury (BPBI) but has limited sensitivity and cannot grade scapulothoracic and glenohumeral mobility. This study aims to evaluate if the addition of a wearable inertial movement unit (IMU) system could improve clinical assessment based on MMS. The system validity was analyzed with simultaneous measurements with the IMU system and an optical camera system in three asymptomatic individuals. Test–retest and interrater reliability were analyzed in nine asymptomatic individuals and six BPBI patients. IMUs were placed on the upper arm, forearm, scapula, and thorax. Peak angles, range of motion, and average joint angular speed in the shoulder, scapulothoracic, glenohumeral, and elbow joints were analyzed during mobility assessments and MMS tasks. In the validity tests, clusters of reflective markers were placed on the sensors. The validity was high with an error standard deviation below 3.6°. Intraclass correlation coefficients showed that 90.3% of the 69 outcome scores showed good-to-excellent test–retest reliability, and 41% of the scores gave significant differences between BPBI patients and controls with good-to-excellent test–retest reliability. The interrater reliability was moderate to excellent, implying that standardization is important if the patient is followed-up longitudinally.
