Hi, Last June I Completely Severed My FHL Tendon And

Hi, last June I completely severed my FHL tendon and never got it repaired. I am walking fine and am able to do everyday activities but I am wondering what I can do to become stronger. I am not longer able to move my big toe. I have been doing a little yoga, mostly sun salutations, but am not wanting to strain myself and would like some advice on whether or not I will be able to do things as I was able to do before severing my tendon.
