A client raises an arm sideways to shoulder height. Which plane primarily describes the movement?
- AFrontal plane
- BTransverse plane
- CScapular plane
- DSagittal plane
Show answer and explanations
Answer
A
Raising the arm directly out to the side is shoulder abduction, which occurs in the frontal plane about an anteroposterior axis.
B
The transverse plane describes rotation and horizontal movements, such as horizontal abduction.
C
The scapular plane lies about 30° anterior to the frontal plane (scaption); straight sideways raising is frontal.
D
The sagittal plane contains forward and backward motions such as flexion and extension.

Raising the arm directly out to the side is shoulder abduction, which occurs in the frontal plane about an anteroposterior axis.
