In health care, the physical examination is a "systematic and thorough inspection of the patient for physical signs of disease or abnormality."[1]
Components of the physical examination
- For links to more information, see: Physical examination: Subtopics
It is usually wise to take the patient's history before performing the physical examination. Knowing the patient's chief complaint, and significant previous history, will guide the examination. If the examiner knows that one of the patient's eyes is prosthetic, it is not necessary to use the opthalmoscope to inspect the (nonexistent) internal eye structures. If a patient is complaining of knee pain, more attention should be given to that area and related topics such as observing the patient walk than, for example, examining the scalp.
Review of systems
There are several ways to perform a basic review; the important aspect is that there should be complete coverage. A common approach is "regional", in which the patient is placed in a series of positions and examining techniques best done in that position are done. [2] Another approach can be slower but sometimes preferable, especially when the examination is focused on a specific system, is to move from position to position looking at aspects of one system at a time.
Regional method
An examination often begins with taking the height and weight if this has not been done; this also gives the examiner to observe the patient's walking gait, apparent balance, and other movement-related signs.
A wide number of observations will be taken in a seated position. Depending on the layout of the examining room, the preference of the examiner, and the comfort of the patient, it may be useful to do some of these while the patient is in a chair, perhaps after the history has been taken from the comfortably seated patient. Some procedures, however, are best done when the patient is seated on the edge of the examining table, so it is simple to move between the patient's front and back.
In the chair, a starting point is taking basic vital signs, [3], inspection of the face including fundoscopic viewing of the eyes and otoscopic viewing of the ears, etc.
Auscultation of the chest is usually easier with the patient sitting on the table, since the examiner will listed from the front and back. Examples of other tests conveniently done in this position include the patellar reflex, examination of the feet and ankles (e.g., skin state, edema, skin sensitivity such as testing for stocking and glove paresthesia).
When the patient is supine, this is the usual time to palpate the abdomen, testing the effect of leg raising in terms of range of motion and specific reactions such as Kernig's and Brudzinski's signs, etc.
Research on the accuracy of the physical examination
Guidelines have been proposed for conducting research on the physical examination.[4]
