This may be far too late to help, but it may come in useful another time, you need to be able to give them quantitative things to compare, so by what degree is movement limited in flexion,extension, etc, something they can use to compare to what they are seeing now, it gives a base line of where the patient is and it is therefore more accurate to see progression, also it is important to say what position the movement is being measured in, e.g there may be decreased hip flexion in standing, but unless you say that it was measured in sanding they may look at it in supine lying, in which case the rom may be different due to the different positional factors affecting the joint,muscles,etc... oh well hope this helps, i do blabber on i'm afraid,i hope you get the jist.
