Sometimes you can’t move your arm on your own because it is too weak, painful, or maybe you are not allowed to actively move your shoulder from a surgery. This video will show you some passive range of motion exercises for your shoulder.
Take a stick of some sort. Broom sticks work well. You are going to do all the movement with your good arm. The “bad” or injured arm is just going along for the ride! First, hold the broom stick straight out in front of you with your good side. Place the other hand on the stick. Lift the stick with the good side slowly, and try to relax the other arm so it does not actively move. Take it as high as you comfortably can, and slowly come back down. Then, put the hand of the bad side on the end of the broomstick. Slowly push the arm out to the side and up, and slowly come back down. Finally, put your elbow by your side with your hand straight out at a 90 degree angle. Put the hand of the bad side on the end of the stick again. Keeping your elbow at your side, push outward slowly until you feel a stretch, and then bring it back in. Do all these 10 times.
