Final answer:
The calcaneal frontal plane position in FP6 can be interpreted as pronated, supinated, neutral, or hyperextended based on the position of the heel bone.
Step-by-step explanation:
The calcaneal frontal plane position refers to the position of the heel bone in the front-to-back direction. In FP6, the possible interpretations are:
- Pronated: This means the heel bone is tilted inward, causing the foot to roll inward.
- Supinated: This means the heel bone is tilted outward, causing the foot to roll outward.
- Neutral: This means the heel bone is in a straight, upright position, neither tilted inward nor outward.
- Hyperextended: This refers to an abnormal position where the heel bone is tilted excessively backward.
To interpret the calcaneal frontal plane position in FP6, you would observe the alignment of the heel bone and determine whether it is pronated, supinated, neutral, or hyperextended based on the defined positions.
