Stand up straight with your affected arm straight down by your side.
Hold a resistance band, or pulley, in your affected hand.
Stand sideways to the band with your affected arm nearest the attachment point, so that the band travels away from your body.
Ensure the other end is tied securely.
Stand firm with your core muscles activated.
Hold the resistance band and pull it down and across the front of your hips.
Slowly return to the starting position and repeat.
