Abstract:
1. A passive motion device for rehabilitative treatment of an elbow or shoulder comprising: a frame transitionable between an operating configuration and a relatively more compact transport or storage configuration, said frame having an upper end and a lower end and further including, a spool rotationally displacable in a first direction or a second direction; a motor linked with said spool to effect motorized rotational displacement of said spool; a cord suspended from a point proximal to said second ends of said first and second uprights by a variable extension length increasing when said spool is rotationally displaced in said first direction and decreasing when said spool is rotationally displaced in said second direction; an arm harness associated with said cord; and a controller in communication with said motor maintaining said motorized rotational displacement of said spool within upper and lower rotational displacement limits corresponding to upper and lower operational limits of said motor.
