Stand upright facing a wall.
Take a resistance band and step on it with one foot to create some tension.
Hold onto the band at the opposite end in your affected hand.
Place a ball between your hand and the wall.
Start with your arm bent by your side, elbow by your hip hand by your shoulder.
Raise your arm up, straightening your elbow.
The ball will travel from your hand to your elbow during this movement.
Make sure you do not hunch your shoulders as you lift the arm against the resistance.
Control the movement back down to the starting position and repeat.
