It sounds like an odd idea, but your brain can’t really tell the difference between thought and reality. This is why athletes visualize, to improve success with difficult-to-achieve movements.
Practice vivid visualizations of the movements you want to recover. Really use your imagination—see yourself moving with less pain, more ease.
Start with what you think is possible, and shoot for the moon as you get better at it. The more you practice, the better your skill. Once you succeed with imagination—with “seeing” yourself doing it with more ease—try imagining the sensations in your body, the feeling of your breath, as your body moves exactly the way you want it to.
