Õlaaduktsioonis

Õlaaduktsioonis, often translated as shoulder abduction, refers to the movement of raising the arm away from the body's midline. This motion is primarily facilitated by the deltoid muscle, with significant assistance from the supraspinatus muscle, particularly in the initial phase of abduction. The range of motion for shoulder abduction is typically around 180 degrees, though this can vary between individuals.

The process involves the scapula (shoulder blade) rotating upwards and outwards, and the clavicle (collarbone) elevating and rotating posteriorly. This coordinated movement allows for a wide arc of motion. Abduction is crucial for numerous everyday activities, such as reaching for objects on a high shelf, putting on a jacket, or swimming.

Injuries or conditions affecting the shoulder joint, rotator cuff muscles, or nerves can impair abduction. Common causes of limited abduction include rotator cuff tears, impingement syndrome, frozen shoulder (adhesive capsulitis), and nerve damage. Rehabilitation exercises often focus on restoring full and pain-free shoulder abduction. The angle of abduction can be further described, for example, "abduction to 90 degrees" or "full abduction."
