Summary: This study used magnetic inertial measurement units (MIMUs) to analyze scapulothoracic movements in stroke patients. The scapulohumeral rhythm (SHR) was found to be impaired in the paretic shoulders, with decreased scapular tilt during maximum arm flexion and arm abduction. The study also found a correlation between the Fugl-Meyer Assessment (FMA) scores and scapular anterior-posterior tilt during shoulder abduction at 60 and 90 degrees.

Summary: Assessment of scapulothoracic and glenohumeral contributions to shoulder function during baseball pitching is challenging due to difficulties in accurately measuring dynamic scapular orientation. A new individualized linear model approach shows promise in estimating scapular orientation and may improve upon current methods like the acromion marker cluster. The study found that the linear model method accurately estimates static scapular orientation throughout a pitching motion, with smaller root mean square error values compared to the acromion marker cluster method.

Summary: This systematic literature review explores the use of wearable systems with magneto-inertial measurement units (M-IMUs) to estimate 3D scapular movements. The results indicate high heterogeneity among studies regarding calibration procedures and sensor placement techniques, highlighting the need for a universal protocol to reduce variability.

Summary: This study evaluated the accuracy of the linear model and D-AMC approaches in estimating scapular orientation in children with BPBI at functional arm postures. The results showed that the D-AMC was similar to palpation in all positions and scapular axes, while the linear model differed from palpation in some instances. Despite the D-AMC outperforming the linear model, both methods still produced clinically meaningful errors.

Summary: The study found evidence of altered muscle activity and shoulder kinematics in individuals with multidirectional shoulder instability (MDI) compared to healthy controls. MDI individuals showed increased or prolonged activity of certain rotator cuff muscles and decreased activity of muscles that move or accelerate the arm, as well as less upward rotation and more internal rotation of the scapula during arm elevation in the scapular plane. Additionally, MDI individuals demonstrated increased translations of the humeral head relative to the glenoid surface.

Summary: This study aimed to improve the accuracy of scapular kinematic estimates in a closed-loop multibody kinematic optimization by optimizing weight sets applied to scapular markers. The results showed that optimizing the weight sets significantly improved the scapular orientation and the optimized sets were participant- and movement-specific.

Summary: This study compared the three-dimensional kinematics of individuals with subacromial shoulder pain (SSP) and a control group during shoulder flexion-extension and abduction-adduction movements. It was found that the SSP group demonstrated specific kinematic alterations during motion, suggesting a need for individualized assessment and treatment approaches for SSP patients.

Summary: This study focused on the kinematic variables involved in functional mobility of the shoulder during scaption motion to distinguish between healthy and diseased shoulders. It found that scapular mobility and velocity are key variables in shoulder assessment. The study highlights the importance of shoulder kinematics, particularly scapular mobility and velocity, in discriminating between patients suffering from shoulder damage and asymptomatic subjects.

Summary: This study developed and assessed new procedures for estimating scapular kinematics by combining closed kinematic chain optimization and double calibration. The results showed that coupling double calibration (using either linear or logarithmic correction) to a closed-loop multibody kinematic optimization is an efficient and fast method for improving scapular kinematic estimates.

Summary: In this study, 3-dimensional shoulder kinematics were compared between breast cancer survivors with and without AWS 5 years postoperatively. The results showed that women with AWS had decreased scapular upward rotation at 120 degrees of arm elevation, which may increase their risk of shoulder pain. These findings can guide rehabilitation programs for breast cancer survivors to facilitate pain-free upper extremity function after treatment.

Summary: For patients undergoing reverse total shoulder arthroplasty (RTSA), limited shoulder abduction is associated with the glenohumeral joint contribution, not scapulothoracic mobility. Good to excellent shoulder abduction requires increasing postoperative abduction strength and improving the glenohumeral joint contribution.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: The existing methods for predicting hip and lumbosacral joint centres in Japanese adults are biased and differ between sexes. We propose new regression equations that consider soft-tissue thickness, sex differences, and a height-directional measure, and validate them using leave-one-out cross-validation.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
