shoulder movements are a complex motor act, controlled by many muscles attached to thescapula and the vertebral column. these muscles are innervating by motoneurons (mns) located in theventral horn of the spinal cord. motoneurons of the ventral horn are arranged such that several groups ofmns can be distinguished in a transverse section through the spinal cord. the anatomical or functionalimpli...

Previous studies have indicated that in 2 muscles of the adult rat, the anterior serratus and the diaphragm, the rostrocaudal axis of the motoneuron pool projects topographically onto the rostrocaudal axis of the muscle. In the present work we have asked whether this orderly topography emerges as a function of postnatal synaptic rearrangement or whether this pattern is already established at bi...

OBJECTIVES/HYPOTHESIS Review the literature on the use of the serratus anterior free flap in the head and neck reconstruction and describe new applications of the serratus anterior free flap. STUDY DESIGN Case series with retrospective chart review and literature review. METHODS A PubMed literature review was performed using the search terms "serratus free flap," "serratus skull base," "ser...

 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...

The purpose of this study was to document the electromyographic activity and applied resistance associated with eight scapulohumeral exercises performed below shoulder height. We used this information to design a continuum of serratus anterior muscle exercises for progressive rehabilitation or training. Five muscles in 20 healthy subjects were studied with surface electrodes for the following e...

[Purpose] This study investigated upper-extremity muscle activities in natural, ideal, and corrected head positions. [Subjects and Methods] Forty subjects with a forward head posture and rounded shoulder were recruited and randomly assigned to the natural head position group (n = 13), ideal head position group (n = 14), or corrected head position group (n = 13). Muscle activities were measured ...

At present, the putative clinical use of the musculocutaneous and ostomusculocutaneous serratus anterior flaps has been compromised by the risk of partial or total necrosis of the skin overlying the lower part of the serratus anterior muscle. Therefore, the aim of this study was to delineate a skin area vascularized by perforant musculocutaneous branches of arteries stemming from the lower segm...

INTRODUCTION Myositis ossificans usually occurs in the vicinity of the elbow, knee joints, or hip joints, following obvious trauma or surgery. This is the first report on myositis ossificans of the serratus anterior. CASE PRESENTATION In this report we present a case of myositis ossificans within the serratus anterior which developed as a complication due to long-term nape massage. The patien...

[Purpose] The present study compared the muscle activity of the upper trapezius with those of the serratus anterior and the lower trapezius when slings, unstable surfaces, were laterally vibrated, to examine the effects of vibration during sling exercises on shoulder stabilization muscles. [Methods] The subjects performed push-up exercises on a sling and maintained isometric contraction in the ...

An in vitro brainstem-spinal cord preparation from adult turtles was used to test the hypothesis that descending synaptic inputs to multifunctional spinal motoneurons (i.e., involved in respiration and locomotion) express activity-dependent depression or potentiation. The tissue was placed in a chamber that allowed for separate superfusion of the brainstem, spinal segments C(2)-C(4), and C(5)-D...
