Which reference point should be Level and Balanced when viewing from the back?

• A. Level and Balanced Scapula
• B. Ears Level
• C. PSIS Level
• D. Knees Level

Answer: (A)

When you’re evaluating alignment from the back, the reference that should be level and balanced is the scapula region—the shoulder blades. Both scapulae should rest at the same height on either side of the spine and sit evenly against the rib cage, without tipping or winging. This balance indicates the shoulders and upper back are centered and the thoracic spine can maintain a neutral line during movement. Why this matters: level, balanced scapulae reflect proper shoulder girdle alignment and scapulothoracic rhythm, which are crucial for symmetrical arm function and overall upper-body posture. If the scapulae aren’t level, you can’t trust that the spine and shoulders are aligned correctly, and compensations may hide in the upper body. Other reference points like ears level, PSIS level, or knees level don’t assess the same upper-body balance from the back. Ears level tells head position more than shoulder symmetry; PSIS level and knees level speak to pelvis or leg alignment, which can be level even when the shoulders aren’t, making them less reliable indicators for back-view posture.
