I am not sure about research on hand movements helping you concentrate, but this reminds me of a therapy which people use for Post-Traumatic Stress Disorder, called Eye movement desensitization and reprocessing (EMDR).
This therapy involves people tracking eye the therapist’s hand moving while they recount their traumatic experience – supposedly the repetitive motion of the eye watching the hand helps them concentrate, and somehow erases the traumatic memory. I don’t know a lot about it, but the theory is that the repetitive motion allows them to concentrate on, and then extinguish the traumatic memory.
I often find that doing something repetitive like drawing or sewing helps me concentrate – I wouldn’t be surprised if by devoting some amount of our cognitive resources to a hand movement, it means you have less available for your mind to wander off and be distracted by other things!
