Summary: This study aimed to investigate whether there are differences in scapular muscle performance during plyometric shoulder exercises when the demand on the kinetic chain is changed. The results from electromyography (EMG) measurements showed that the muscle ratio of upper trapezius to serratus anterior was lower under high demand on the kinetic chain. Additionally, the prone position resulted in higher activity of scapular and trunk muscles compared to the side and standing positions.

Summary: This study explored the activity of deeper-layer scapular muscles and related ratios during 4 shoulder exercises. It suggests performing side-lying external rotation and side-lying forward flexion exercises to strengthen the middle and lower trapezius, even in cases of hyperactivity of the pectoralis minor. However, caution should be taken when prescribing the 4 exercises to patients with hyperactivity in the levator scapulae and/or rhomboid major.

Summary: This study analyzed the muscle contribution to the static body-weight wall-squat exercise and found that shifting the center of pressure from the forefoot to the rearfoot increased the activity of the vastus medialis, vastus lateralis, and tibialis anterior. Maximizing lumbar muscle activity was achieved by shifting the center of pressure at the forefoot, placing the center of pressure exerted by the wall on the back at the scapular zone, and keeping the feet far from the wall. This exercise is suitable for patients with low back pain and limited lumbar muscle endurance, or quadriceps weakness and inhibition secondary to a knee injury.

Summary: This study compared the effects of isometric horizontal abduction (IHA) during wall push-up plus (WPP) and wall slide (WS) exercises in individuals with scapular winging (SW). It was found that IHA increased the activity of shoulder stabilizers and decreased pectoralis major (PM) activity. WS exercises were more effective in increasing the activity of lower trapezius (LT). These exercises can enhance the activity of shoulder stabilizers and prevent overactivation of PM.

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 reported 4 clinical cases of isolated DSN compression and proposed a specific rehabilitation protocol. DSN neuropathy was confirmed by electroneuromyographic testing, with partial correction of scapular winging and residual pain observed in some patients. In one patient who underwent rehabilitation, signs of muscle denervation improvement were observed during follow-up.

Summary: This study compared the use of HRUS and EDX in diagnosing patients with scapulae alatae. The findings showed that HRUS could help identify muscle atrophy and nerve diameter enlargement, supplementing EDX in the diagnostic workup.

Summary: This study compared the effects of four exercises with shoulder elevation below 90 degrees on the EMG activity of four shoulder girdle muscles, while considering sex effects. The side lying external rotation and the wall slide exercises produced the highest peak EMG activation for the lower trapezius, both 33% and 29% lower than the Y prone. In terms of the ratio between upper trapezius and lower trapezius, the side lying external rotation had the lowest value, followed by the Y prone and wall slide (53% and 59% respectively higher). Therefore, side lying external rotation and the wall slide are recommended for targeting the lower trapezius muscle during early rehabilitation.

Summary: The aim of this study was to identify predictive factors and their interactions in discriminating positive and negative Scapular Assistance Test results in individuals with shoulder pain during arm elevation. The study found that the angular onset of pain, scapular dyskinesis, pain catastrophizing, serratus anterior and lower trapezius muscle strength were the main predictors. Disability of the upper limbs did not contribute to the test results.

Summary: This study synthesized existing literature and found that using unstable surfaces for push-ups doesn't necessarily increase the activity of all scapular stabilizer muscles. The amount of muscle activity depends on the type of push-up rather than the type of support base. If an unstable surface is used, the push-up plus exercise appears to be the most effective modality for improving training quality, performance, and preventing scapular dyskinesis due to increased activity of the middle trapezius and serratus anterior muscles.

Summary: There is no difference in upper limb muscle electromyographic (EMG) activity between subjects with and without scapular dyskinesis during bench-press and dumbbell fly exercises. Inserting unstable surfaces did not modify EMG activity.

Summary: This study assessed the surgical and patient-based outcomes of open reduction and internal fixation for displaced scapula fractures, following predefined operative indications. The results showed that good functional outcomes and low complication rates could be achieved with this treatment approach.

Summary: Injuries to the spinal accessory nerve can result in shoulder pain and restricted mobility, with physical therapy being a potential treatment option. Further research is needed to establish evidence-based guidelines for managing shoulder dysfunction secondary to spinal accessory nerve injuries.
