You could track points on the arms to control the motion of a shape layer with a row of points or short strokes on it, then apply the **echo** effect. How well that would work would depend on the speed the arms move.

You could also apply the tracking to some nulls, and copy their motion paths onto a shape layer's path property, or the path property of a write-on effect.
