Instead, I would ask myself:
1. Is the wrist locked or not?
That is the question.
2. If the hand-wrist-forearm are locked in one straight pole, like a
rotisserie spigot, then use the Rotisserie Symbol (grin ;-)))
3. If your movement unlocks the wrist joint and some movement is from
the wrist (even if there is other movement from the elbow joint
too)...the MOMENT there is wrist movement involved with an "unlocked
wrist"...that takes WRIST MOVEMENT symbols.
