“…Our study results show that limitations in shoulder external rotation and abduction are mainly active, whereas the restriction in shoulder internal rotation has both active and passive components. Although limitations in active shoulder external rotation and abduction are common in these patients, increased postural internal rotation in many tasks of upper extremity is also reported (Mahon et al., 2018). Limitation in active shoulder external rotation and abduction is a result of loss of strength due to denervation (Pons et al., 2017).…”

The aim of the study was to determine the differences in upper limb function and activity/participation levels between preschool children with Narakas Groups 2a and 2b obstetric brachial plexus injury; and to determine the significance level of the factors affecting upper limb functions in these patients. Sixty-seven children, aged 3 to 7, who had not had surgical intervention, were evaluated in terms of joint movements, modified Mallet classification, Raimondi hand classification, brachial plexus outcome measure, paediatric outcome data collection instrument and stereognosis. There were significant functional differences between the groups, in favour of Group 2a. The movements affecting total function of the upper limb were: hand to spine ( p < 0.001), global abduction ( p < 0.001) and hand to mouth ( p < 0.001), in descending order of significance. Passive internal rotation was the most important passive joint movement affecting shoulder function ( p < 0.001). The results of this study suggest that more emphasis should be placed on the shoulder internal rotation in treatment strategies. Level of evidence: III

“…The compensatory maneuvers of some patients with BPI, wherein a greater contribution by the trunk, scapulothoracic, and humeralthoracic joints is present to facilitate a movement normally achieved by primary contribution of the normal glenohumeral joint has been documented. 44,46,54,55 For example, Mosqueda et al 46 describes how patients with BPI would swing their arms around their backs to abduct their affected shoulders.…”

Introduction. Brachial plexus injuries (BPI) have devastating functional effects. Clinical outcomes of BPI reconstruction have been documented in literature; however, these do not use EMG and quantitative kinematic studies.Objective. This study aims to use a markerless motion analysis tool (KINECT) and surface EMG to assess the functional outcomes of adult patients with traumatic upper trunk BPI who have undergone nerve transfers for the shoulder and elbow in comparison to the normal contralateral limb.Methods. This is an exploratory study which evaluated three participants with BPI after nerve reconstruction. KINECT was used to evaluate the kinematics (range of motion, velocity, and acceleration) and the surface EMG for muscle electrical signals (root mean square, peak EMG signal, and peak activation time) of the extremities. The means of each parameter were computed and compared using t-test or Mann-Whitney U test.Results. Participant C, with the best clinical recovery, showed mostly higher KINECT and EMG values for the BPIextremity. There was a significant difference between the KINECT data of Participants A and B, with lower meanvalues for the BPI extremity. Most of the EMG results showed lower signals for the BPI extremity, with statisticalsignificance.Conclusion. The KINECT and surface EMG provide simple, cost-effective, quick, and objective assessment tools.These can be used for monitoring and as basis for formulating individualized interventions. A specific algorithm should be developed for the KINECT sensors to address errors in data collection. A fine needle EMG may be more useful in evaluating the muscles involved in shoulder external rotation.

“…Another approach is to use a three-dimensional kinematic analysis of the shoulder complex [ 12 , 21 , 22 , 23 ]. 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 ].…”

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.
