Stand under your shoulder pulley device and hold on to the handles, with both arms in front of you.
Extend both arms in front of your chest.
Pull down slowly on the handle in front of your chest to assist you raising your opposite arm above your head.
Gently guide your arm back down by slowly raising your other hand back to the start position.
Either alternate the side you raise by pulling down on the opposite handle, or repeat this action on the desired side as guided by your physiotherapist.
