I'm currently doing physio rehab for a sprained ankle so thought I'd chime in. The exercises I'm doing rn are all of the above plus the following.
Seated calf raises. Sit down with your knees bent 90 degrees and just lift your heels with your toes on the floor, you'll feel a stretch through your calves. 3 sets of 7, or however many you're comfortable with.
Standing in front of a bench or high table that you can rest your hands on, take turns balancing on one foot, taking as much weight off as you need to, just with your finger tips. Alternate between feet, starting with 10 seconds each, 3 sets. When you can get to 60 seconds each side without needing to use your hands, start trying to do it with your eyes closed. If you can do 25-30 seconds without using your hands, you're doing great, but don't over do it, and don't fall over.
"opening the clam"
Lie on your side, knees bent 90 degrees, head on a pillow, with your feet together. With your hips rolled forward, try and lift your top knee as far as you can without your toe or heel lifting away from the other foot, like your legs are the mouth of a clamshell opening and closing. Start with 3 sets of 7 and build from there.
Some of these exercises are to build strength in your ankle and some are to build strength in other parts of your legs. Your hips, knees, calves and ankles all work in tandem, so strengthening the other parts of your legs takes pressure off your ankles.
Hope some of these help. I'm still early on in recovery, so if you want me to keep you updated with new exercises as I'm given them let me know.
