Muscles of the Shoulder01:23

Muscles of the Shoulder

9.4K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Stability of structures

677
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Degenerative Disc Disease I: Introduction

29
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

Degenerative Disc Disease ll: Pathophysiology

30
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

Muscles that Move the Arm01:31

Muscles that Move the Arm

5.5K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

40
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Summary
This summary is machine-generated.

Athletes with shoulder dysfunction exhibit poorer balance and core stability. Incorporating balance training into core stability programs can aid in the rehabilitation of overhead athletes with shoulder injuries.

Area of Science:

  • Sports Medicine
  • Orthopaedic Surgery
  • Rehabilitation Science

Background:

  • Overhead athletes frequently experience glenohumeral joint instability and injuries.
  • The link between core stability and shoulder dysfunction in athletes remains underexplored.

Purpose of the Study:

  • To compare core stability measures between healthy athletes and those with shoulder dysfunction.
  • To investigate the relationship between core stability and shoulder dysfunction metrics.

Main Methods:

  • NCAA Division III overhead athletes (n=61) were assessed.
  • Evaluated core stability using Single-Leg Stance Balance Test (SLBT), Double Straight Leg Lowering Test (DLL), Sorensen Test, and Modified Side Plank Test.
  • Assessed shoulder function with Kerlan-Jobe Orthopaedic Clinical Scale (KJOC) and QuickDASH sports module.

Main Results:

  • Athletes with shoulder dysfunction demonstrated significantly poorer performance on the Right SLBT compared to controls (p = .038).
  • A positive correlation was observed between DLL and KJOC (r = .394).
  • A negative correlation was found between Right SLBT and Quick DASH sports module (r = -.271).

Conclusions:

  • Balance deficits are evident in athletes experiencing shoulder dysfunction.
  • Increased shoulder dysfunction correlates with diminished balance and core stability.
  • Balance training should be integrated into core stability rehabilitation for athletes with shoulder dysfunction.
