stand with swiss ball between back and wall, squat down while maintaining ball contact, then return to start.
Stand facing against the wall with feet apart, place a swiss ball between wall and trunk and rest your back on it, and cross arms over the chest. With maintaing the contact with ball slide down and bent your knee same as squat and return to starting position and repeat it.
Nothing here is a prescription. Your physiotherapist decides which of these are yours, and when.
