Quantitative assessment of head and shoulder posture.

摘要: Abstract Posture of the head, neck, and shoulders has long been recognized as a factor contributing to onset perpetuation cervical pain dysfunction syndromes. Treatment regimens frequently include exercises instruction for postural correction. Clinical assessment posture, however, tends be subjective in nature. The purpose this study was determine reliability new objective technique posture measurement establish normal standards technique. This used computer-assisted slide digitizing system called Postural Analysis Digitizing System (PADS) characteristic values head shoulder girdle range motion protraction-retraction sample able-bodied young men. PADS is modification two-dimensional developed measuring trunk motion. Twenty male subjects were photographed neutral position, maximally protracted retracted position scapula. Ten evaluated once, ten twice. photographs analyzed using system. Well-defined anatomic landmarks angular relationships shoulders. tested by calculating an intraclass correlation coefficient, student t -test, percent error each position. positions considered reproducible, adequate analysis. Mean 28.48°, 51.97°, 62.09° protraction, retraction, respectively. Shoulder measurements 131.08°, 98.53°, 67.49° average 33.62° from 63.58°
