Best advice i've heard or passed on for people worried about outpatients is to draw up a simple problem list with what you've found eg weakness, lack of ROM etc, including there functional problems and treat what you find - if there's stiffness focus on movement, if there's weakness strengthen and if it's a functional task either practice it or practise components of it( eg walking after a # - get them to do it non or partial weight bearing in a pool and focus on technique
