A scoping review of tendon transfer surgeries and postsurgical physical therapy interventions in individuals with massive rotator cuff tears.

Objective: To identify tendon transfer surgeries and postsurgical physical therapy interventions in people with massive rotator cuff (RC) tears.

Methods: The literature search was conducted in the MEDLINE, Science Direct, Scopus, Web of Science, and PEDro databases from inception to September 2022. Studies with patients diagnosed with massive RC tears undergoing tendon transfers that reported physical therapy interventions after surgery were included.

Structural and functional brain changes in people with knee osteoarthritis: a scoping review.

Background: Knee osteoarthritis is a highly prevalent disease worldwide that leads to functional disability and chronic pain. It has been shown that not only changes are generated at the joint level in these individuals, but also neuroplastic changes are produced in different brain areas, especially in those areas related to pain perception, therefore, the objective of this research was to identify and compare the structural and functional brain changes in knee OA healthy subjects.

Methodology: Searches in MEDLINE (PubMed), EMBASE, WOS, CINAHL, SCOPUS, Health Source, and Epistemonikos databases were conducted to explore the available evidence on the structural and functional brain changes occurring in people with knee OA.

Electromyographic analysis of the serratus anterior and upper trapezius in closed kinetic chain exercises performed on different unstable support surfaces: a systematic review and meta-analysis.

Background: Multiple investigations have compared the electromyographic (EMG) activity of the scapular muscles between stable and unstable support surfaces during the execution of closed kinetic chain exercises. However, these comparative analyses have grouped different unstable surfaces (wobble board, BOSU, therapeutic ball, and suspension equipment) into a single data pool, without considering the possible differences in neuromuscular demand induced by each unstable support surface. This study aimed to analyze the individual effect of different unstable support surfaces compared to a stable support surface on scapular muscles EMG activity during the execution of closed kinetic chain exercises.

Optimal activation ratio of the scapular muscles in closed kinetic chain shoulder exercises: A systematic review.

Background: Muscle synergies contribute to scapular position during arm movement. The trapezius and serratus anterior (SA) muscles are the main stabilizers and are therefore the main target muscles of therapeutic exercises.

Objective: To systematically review the current literature investigating the optimal activation ratio of the scapular muscles during a range of closed kinetic chain exercises.

Influence of adiposity and fatigue on the scapular muscle recruitment order.

Background: Several authors have indicated that excess body weight can modify the electromyographic (EMG) amplitude due to the accumulation of subcutaneous fat. This accumulation of adipose tissue around the muscle would affect the metabolic capacity during functional activities. On the other hand, some authors have not observed differences in the myoelectric manifestations of fatigue between normal weight and obese people.
