In golf, the medicus company makes hinged clubs with 1 or 2 hinges. These are good for giving feedback concerning staying connected in the rotational component of the swing, However, the hinge can breakdown if the club/bat is swung too much out of a single plane.

Some high level golfers and many more high level hitters swing the club/bat out of plane to optimize loading (often early "THT" is applied out of plane/druing a smooth transition into the unloading/power plane) before the club/bat unloads in the 2D power plane.The hinge bat will interfere with learning what is an optimal loading method for many.
