Using an Apple Watch on ankle.
I have a disability that I can’t use my upper body, my arms or my hands so I use my feet for everything.
is there a way to track my sleep patterns and movements on a Apple Watch?

Technically you can if you can find an appropriate band to wear it there but Apple doesn’t actually suggest the watch for anywhere other than the wrist. No guarantee that readings will be accurate. You may want to reach out to Apple directly though to discuss this and make your decision from there.
