Most antenna rotators have two parts, the rotator unit and the controller.
Hence, restricted external rotation can encourage adaptive shortening and thickening of the internal rotators of the shoulder principally the teres major and subscapularis.
The supraspinatus is most commonly involved in a rotator cuff tear.
The intrinsic muscles of the scapula include the muscles of the rotator cuff- the subscapularis, teres minor, supraspinatus, and infraspinatus.
The posterior capsule is a band of fibrous tissue that interconnects with tendons of the rotator cuff of the shoulder.
Traumatic rotator cuff changes are often located antero-superior, meanwhile degenerative changes more likely are supero-posterior.
The kicked rotator approximates systems studied in the fields of mechanics of particles, accelerator physics, plasma physics, and solid state physics.
The combination of a precision rotator and a digital camera allows the photographer to take rectangular slices of any scene (indoors or outdoors).
