All of these are possible postural deviations in the frontal plane EXCEPT (Multiple answers can be correct. Select all that apply):
A) Genu valgus
B) Hip drop
C) Genu Recurvatum
D) Toe out
E) All are in the frontal plane
To determine which of the given options are possible postural deviations in the frontal plane, we need to understand what the frontal plane is and the potential deviations that can occur within it.
The frontal plane, also known as the coronal plane, divides the body into front (anterior) and back (posterior) halves. It runs vertically from side to side, perpendicular to both the sagittal plane (which divides the body into left and right halves) and the transverse plane (which separates the body into upper and lower halves).
Now, let's examine each option:
A) Genu valgus: This refers to a deviation at the knee joint where the lower leg angles inward towards the midline of the body. Genu valgus is a possible postural deviation in the frontal plane.
B) Hip drop: This is a downward drop or tilt of one side of the pelvis when standing or walking. Hip drop is also a possible postural deviation in the frontal plane.
C) Genu Recurvatum: This is an excessive backward curvature of the knee joint, causing the knee to extend beyond a neutral position. It occurs in the sagittal plane rather than the frontal plane, so Genu recurvatum is not a possible postural deviation in the frontal plane.
D) Toe out: This refers to an external rotation of the feet where the toes point outward instead of straight ahead. Toe out is a possible postural deviation in the frontal plane.
Based on the explanations above, the correct answer is:
C) Genu Recurvatum
Therefore, all the other options (A) Genu valgus, B) Hip drop, and D) Toe out) are possible postural deviations in the frontal plane.
