Patent ID: 7621857

Claim:
An apparatus for use in exercising the shoulder, comprising: a motion assembly having a stacked arrangement of first, second and third stages with (i) said first stage being coupled to said second stage to permit relative one-dimensional straightline motion therebetween, and (ii) said third stage being coupled to said second stage to permit relative in-plane rotational motion therebetween, said motion assembly further including means for selectively limiting said relative one-dimensional straightline motion and said relative in-plane rotational motion; an arm having first and second ends, said first end being coupled to said second stage of said motion assembly, and said second end being adjustably positioned relative to said first end; means for padding said second end; a handle coupled to said third stage and adapted to be grasped by a user; and a base assembly coupled to said first stage of said motion assembly for positioning said motion assembly at a selected vertical height, a selected pitch position, and a selected yaw position, and for fixing said motion assembly in at least said selected vertical height.
