I agree with Alophysio, You cannot really set a number. In my organization the administration expects us to see upto 24 patients within our 8 hours work shift... meaning 3 patients per hour. Ofcoarse, clinically it is not so, I see about 7 to 14 patients a day. treatment time varies greatly, if it is an exercise patient, then i give them an hour session... where as a patient requiring electrotherapy as well as exercise therapy gets 30 minutes a session.
But then again, here poeple never stick to their appointment timings so i always end up hopping around like a bunny rabbit...
