DIFFERENTIAL DIAGNOSIS OF THE NEUROMUSCULOSKELETAL SYSTEM
Differential diagnosis is used to differentiate between one or more conditions, diseases or injuriesa patient is suffering from and complaining of by systematically comparing and contrasting theirsigns and symptoms.
The process of a differential diagnosis may involve a combination of clinical diagnosis, physicaldiagnosis, pathological diagnosis, a provocative diagnosis, laboratory diagnosis, and diagnosticimaging.
To perform a differential diagnosis, the examiner must have a good basic knowledge of pathologyand the process of tissue healing. As well, background knowledge in conditions and theirpathology, and signs and symptoms axe a definite asset.
To provide a systematic examination process to arrive at a differential diagnosis, the assessmentwill be described under the following headings:

Slow or sudden onset?
Has it occurred before?
How long has it been present?
What affects it?

The observation is the "looking" part of the examination. It primarily involves looking at theposture and noting any asymmetry.

EXAMINATION
The examination involves movement testing combined with ligament testing and other provactivetests to enable one to differentiate between inert tissue, contractile tissue and nervous tissue,between nerve root symptoms and peripheral nerve symptoms, functional assessment, betweenjoint problems and surrounding structures. Mso included is palpation and diagnostic imaging.

Apply overpressure with care Repeat or sustain movements if history !ndicates Do resisted isometric movements in a resting position With passive movements and ligamentous testing, both the degree and quality of opening
axe important With ligamentous testing, repeat with increasing stress Myotome testing must be held for 5 seconds

On active movements, note:
When and where during each of the movements the onset of pain occurs
Whether the movement increases the intensity and quality of the pain The reaction of the patient to pain

Table 15. Rules for Joint Play Testing
The patient should be relaxed and fully supported
The examiner should be relaxed and use a firm but comfortable grasp
One joint should be examined at a time One movement should be examined at a time
The unaffected side should be tested first
One articular surface is stabilized while the other surface is moved
Movements must be normal and not forced
Movements should not cause undue discomfort
