Elastic arc anatomical shoulder pulley system

Abstract

An Elastic Arc Anatomical Shoulder Pulley System for use in rehabilitation of various shoulder conditions. The device provides a means that a user can employ to produce passive shoulder motion that approximates the normal arc the shoulder describes during active movement. A door unit is included that allows for a convenient attachment site of a pulley. An arc that has elastic properties is routed through a pulley that is located above the user's head. Handles are attached to the elastic arc. The user pulls down on one handle to accomplish upward movement of an injured arm. The arc shape of the elastic arc insures that the movement produced corresponds to the normal arc shaped movement of the shoulder that is produced during active movement.

1 . An Elastic Arc Anatomical Shoulder Pulley System for producing passive movement of a user's shoulder in an anatomical arced fashion consisting of:
 a. a door unit with means of attaching said door unit to a standard door   b. a pulley and pulley height adjuster that are attached to said door unit   c. an elastic arc   d. upper and lower handles   
   
   
       2 . The device of claim one wherein said elastic arc is formed of material allowing elastic deformation of said elastic arc and return to the original shape. 
   
   
       3 . The upper and lower handles of claim one wherein said upper and lower handles are flexibly and detachably connected to said elastic arc. 
   
   
       4 . The pulley and pulley height adjuster of claim one wherein said pulley height adjuster provides a means of adjusting the vertical height of said pulley.
