1. A continuous passive motion manipulation device for exercising a patient'"'"'s arm and shoulder comprising:
- patient seating means;
a motivator assembly attached to said seating means for synchronous manipulation of elevating and rotating the patient'"'"'s arm and shoulder wherein said motivator assembly comprises;
a first drive means for arm elevation connected between a first arm means for operatively connecting the patient'"'"'s upper arm and the seating means, and a second drive means for arm rotation connected between the first arm means and a second arm means for attaching the patient'"'"'s forearm such that the axis of rotation of the second drive means is aligned with the humerus of the patient;
a pivotable orthosis connected to said motivator assembly for holding the arm during said manipulation, andprogrammable means for controlling said arm elevation means and the arm rotation means, programmed to avoid physiologically incompatible combinations of arm elevations and arm rotations capable of producing arm or shoulder trauma.

Abstract
A continuous, passive motion device includes a chair to which a motivator assembly is attached for exercising the arm and shoulder of a patient seated therein. The assembly has two interconnected drive units, one of which provides elevation of the arm and the other its rotation when the arm is positioned in a connected pivotal orthosis. The drive units communicate with each other through a microcontroller programmable to avoid exercise physiologically incompatible with the patient'"'"'s proper range of movement, thereby avoiding exercise-induced trauma.

15. A continuous passive motion apparatus for exercising a patient'"'"'s arm and shoulder by synchronously elevating the arm about the shoulder joint and rotating the arm about the longitudinal axis of the humerous comprising:
-
a first drive means for arm elevation connected between a first end of an elevation pivot arm for operatively connecting the patient'"'"'s upper arm and a seating means, a second drive means for arm rotation connected between a second end of the elevation pivot arm and a first end of a rotation pivot arm for attaching the patient'"'"'s forearm such that the axis of rotation of the second drive means is aligned with the humerus of the patient, the arm cradle means being supported by at least one of said elevation and rotation pivot arms, and programmable means to coordinately control the first drive means and the second drive means. - View Dependent Claims (16, 17, 18)
