How about you nail your foot to the floor (well, the less painful way is to put it under the couch) and then dorsiflex and see what happens, eh? Or since you're still likely to confuse it with weight, how about you nail it to the ceiling and then dorsiflex and see what happens, eh? I leave it to you to find a less painful experiment along the same lines.
p.s. Do you see where using too many misunderstood anatomical terms leads us to? And if you still think the misunderstanding is on our side (i.e. the 3-4 that you keep contradicting) we're still not in a better place.
The definition of dorsiflexion I used perfectly fits the definition of flexion you are giving me right now... Moreover, on that same wikipedia page you just posted they are giving a very clear and concise definition of dorsiflexion --> Dorsiflexion where the toes are brought closer to the shin. This decreases the angle between the dorsum of the foot and the leg. For example, when walking on the heels the ankle is described as dorsiflexion.
Everything has become pretty clear in the end right? At least I think I am understanding what everyone has been trying to say so far.
no, see, you inssist on getting in backwards.
the definitions in the article I quoted are, in order:
describes a bending movement that decreases
the angle between a segment and its proximal segment. For example, bending the elbow
, or clenching a hand into a fist, are examples of flexion. When sitting down, the knees are flexed. When a joint can move forward and backward, such as the neck and trunk
Those are all, 4 of them in sequence, examples where either side of the joint, or both, move. That is flexion.
Dorsiflexion and plantar flexion refers to extension or flexion of the foot at the ankle.
Where dorsiflexion is clearly defined as flexion. See flexion above.
These terms refer to flexion between the foot and the body's dorsal surface, considered the front of the leg, and flexion between the foot and the body's plantar surface, considered the back of the leg.
Again, either part of the joint can move, since flexion refers to a joint.
And only then do they give an example, which in your mind, somehow, became the definition:
where the toes are brought closer to the shin
. This decreases the angle between the dorsum of the foot and the leg
For example, when walking on the heels
the ankle is described as dorsiflexion.
And to be crystal clear, again, they immediately give a definition and examples for plantar flexion:
is the movement which decreases the angle between the sole of the foot and the back of the leg. For example, the movement when depressing a car pedal
or standing on the tiptoes can be described as plantar flexion.
Note that they are both movements that increase or decrease angles.
p.s. flexion in english means: https://en.wiktionary.org/wiki/dorsiflexion
Nothing to do with pulling the toes up - that's a different movement altogether.
