老年人做完HIP手术后的康复运动

last time I reported that my dad, who is 80 year old and has parkinson, fell and broke his leg.

He eventually had HIP surgery on Jan 5, and got out of the hosiptal on Jan 15. He is doing fine. 

I would like to ask what kind of 康复运动 he has to do to help him be able to walk again. Any recommendations? tips? video? 

Thanks
