[Star Wars] Are hand movements and gestures needed to use the Force or are they just a way to focus it?

The hand gestures are a bit like a meditation tool or pose, giving the user something to focus on to help them concentrate and center themselves. It also has a bit of a placebo effect. Reaching out your hand makes someone believe that they can lift a rock with the Force which actually helps them.

All that's really needed to use the Force is to stretch out with your feelings.
