It seems to be a medical skill,It's interesting. Shizune indeed moved the hair somehow. But I don't think Kishimoto intended to make it any sort of telekinesis.
Sakura did it with the Water, and to extract the poison from out of kankuros body.
I think she did it to pump naruto's blood through his body, though, she couldve used her strength.
Orochimaru did it with his sword. Idk if it was filler or not.
