The study of myology is relevant for both functional understanding and distinguishing different species. The pine marten (Martes martes) is a small carnivore found in Europe and Western Asia and belongs to the Mustelidae family. For the purpose of this study, fresh a carcass which was found in the hunters' trap, was brought to the anatomy hall of veterinary faculty, for anatomical studies. Afte...

BACKGROUND A substantial number of children with an obstetric brachial plexus lesion (OBPL) will develop internal rotation adduction contractures of the shoulder, posterior humeral head subluxations and glenohumeral deformities. Their active shoulder function is generally limited and a recent study showed that their shoulder muscles were atrophic. This study focuses on the role of shoulder musc...

BACKGROUND Strength improvement of the shoulder muscles is a major goal in rehabilitation or athletic conditioning programs. The purpose of this study was to determine the effect of shoulder core exercises on the isometric torque of glenohumeral joint movements. METHODS A total of 36 healthy females with no history of shoulder injury enrolled in this study. Subjects were randomly assigned int...

[Purpose] The purpose of this study was to compare the upper, middle, and lower trapezius muscles' activity in the different planes of shoulder elevation. [Subjects] Twenty male subjects volunteered for this study. [Methods] Surface electromyographic (EMG) activity for each of the three regions of the trapezius muscles in the three different planes of elevation were collected while the particip...

The purpose of this study was to determine if a difference existed in the rate of fatigue of select shoulder muscles during isometric shoulder elevation and if the measured rate of fatigue was consistent from day to day. Shoulder muscle fatigue has been associated with alterations in joint mechanics and possibly contributes to shoulder dysfunction. While research exists, there is limited inform...

 Postural disorders disrupt muscle activity and lead to joint dysfunction. Maintaining the function of the shoulder joint requires precise coordination and on-time action of muscles, and its dysfunction lead to change in the level of muscle activity, movement disorder. This study aimed to measure the effects of corrective exercise program with kinesiotaping and physio-ball and durability of the...

Patients with hemiplegia usually have weak muscle selectivity and usually perform strength at a secondary joint (secondary strength) during performing a strength at one joint (primary strength). The abnormal strength pattern between shoulder and elbow joint has been analyzed by the maximum value while the performing process with strength changing from 0 to maximum then to 0 was a dynamic proces...

Prior work has shown that cerebellar subjects have difficulty adjusting for interaction torques that occur during multi-jointed movements. The purpose of this study was to determine whether this deficit is due to a general inability to generate sufficient levels of phasic torque inability or due to an inability to generate muscle torques that predict and compensate for interaction torques. A se...

STUDY DESIGN This study used a prospective, single-group repeated-measures design to analyze differences between the electromyographic (EMG) amplitudes produced by exercises for the trapezius and serratus anterior muscles. OBJECTIVE To identify high-intensity exercises that elicit the greatest level of EMG activity in the trapezius and serratus anterior muscles. BACKGROUND The trapezius and...

The aim of this presentation is to discuss the current literature and opinions on the biomechanics of the rotator cuff and relate this to the clinical relevance in rotator cuff tears. I intend to cover: Relate Biomechanics to Clinical Relevance 1. Cuff Mechanics 2. Tendon Anatomy – layers, microanatomy, blood supply 3. Pathomechanics of cuff tears The shoulder complex comprises 30 muscles. Thes...
