A look at Ideal Posture from the side and from the rear
Posted Aug 26 2008 12:32pm
One of the key indicators of poor health can be a person's posture. Today I want to go over proper posture and what it really means. From the side and from the back (see below Figure A and Figure B)- what should you look like if you have perfect ideal posture- that is the key question.
When in a standing position, muscles are not activated to maintain proper posture especially if standing straight.
According to Kendall and McCreary* there are certain points on our bodies that are key to determine if we have ideal posture. From the side position, as shown in Figure A, a line drawn from the head to the toes (also known as a plumb line) will pass the following target points:
midway through the shoulder joint
midway through the trunk
through the greater trochanter (see figure C below)
slightly in front of the lateral malleolus (see figure D below)
Figure C: Greater Trochanter
Figure D: Lateral Malleolus
If we look at an individual from the rear aspect as in Figure B, the plumbline should fall directly in the middle of the body, and we should see the shoulder and the pelvis align on the right and left. The head should be in a neutral position, the hips should be aligned and the feet should be turned outward slightly.
