Was that really 3 point non-weight bearing? Is it not supposed to be the crutch on the injured side (non weight bearing foot) going forward first followed by the crutch on the functional side then finally the uninjured foot moving to or through.
I suspect you know this but demonstration down the first step did include some weight bearing on the affected side: I suspect you were trying to have her be NWB as she was in subsequent steps?
The section on toe touch weight bearing is wrong - the patient in this video is doing is more partial weight bearing / heel touch. This is not toe touch weight bearing
