Hi Kayelle...
ok... breathe... third year means you're not expected to know how to handle it all! Do you have a good rapport with your supervisor?? They would be the best person to approach about how you're coping. It's guaranteed that you're not the first student who's not sure on how to tackle the OPD, but your supervisor can help you with direction for patients, where to find information, and adapt your workload to suit... you need to be able to take on enough clients to get a feel for things but not so many that your brain explodes and you don't end up learning anything.
When in doubt... go back to basics. Know your anatomy (this is one of my soapboxes when I supervise students)... if you know what bits are where, and what they're meant to do, then you can figure out what isn't happening and how to perhaps start things doing what they're meant to!
Also think FUNCTIONAL... clients/patients are WAY more likely to be compliant with your programs if it's relevant to them and they can see/understand why they're doing something. if you can't justify what you want to do (either manual treatment or exercise plan) to the patient in a way they can understand... then have you chosen the right thing?? try selecting only 1 or 2 really functional exercises for the client to do that you can measure each week and they can feel/see results.
As far as information/treatment ideas goes, i'm not going to do your homework for you... make sure you know your anatomy, and what should be normal (joint mov't, gait, weightbearing, proprioception etc) and start there.... and do talk to your supervisor - you'll be looked upon far more favourably if you can recognise when you need guidance (but not spoon-feeding) and seek it appropriately.... we all do this still and it's a healthy reflection of practice.
Don't panic!
