It all also depends on how much space you have, in which you can take on patients at a time. i normally take 4-5 patients at a time. Assessments take 45 minutes. Treatment normally take 30-40 minutes, sometimes longer. Iam into private practice in Mumbai, India,& in order to reduce the waiting period for an initial appointment, I prefer to have physios at various levels. The juniormost starts with assessments. Conclusion to the assessment is normally done by myself or the physios at the top of the hirarchy. Those who have been with me for some years normally would only review or give specific manual therapy techniques.This gives me the time to review every patient's progress, build relations, get maximum results in minimum sittings. i also tend to keep one physio extra so that the running is smooth even if some one reports sick. Hence although the number of patients you see in a day would differ due to various factors, to do a good job, anywhere in the world it would take you 45 min for assessment & minimum 30 min for the followup's. Neurodevelopmental treatment normally take about 45min's-1 hour. Hospitals here private as well as government, tend to have a huge load of patients & they are always complaining of being understaffed.
