Sorry hariharan but are you suggesting they persist with the altered pattern?

I would get this person walking as normally and as often as possible. No matter how long your treatent session is with them, it will never be as long as what they have to do when you are not there.

You have not mentioned any pain at all therefore i would pursue this line (make them walk).

You mention that she is young - how young is young?

Also, the more passive treatment you give her, the more she will think she needs you to help her.

To be honest, her symptoms sound like a typical stiff ankle following immobilisation. It just needs to get moving. Your role should be to give her the confidence she needs to use the ankle again.

Lastly, it is a fibular fracture - assuming no other damage like talar dome osteochondral lesion etc. Therefore get her going on it and make her do it. Get tough!

Hopefully this advice isn't too shocking. Obviously i don't have all the information or done an assessment but just getting her going as much as possible on it.

Good luck!
