Evaluation of body posture
Alterations of body posture can result from Central Nervous System (CNS) and Peripheral Nervous System (PNS) lesions causing a regulatory loss of body control,
but can certainly also be caused by pain. Such discom- fort associated alterations of body posture may originate from CNS or PNS disease (for example disc herniation and brachial plexus neoplasm associated pain) or from conditions outside the CNS/PNS such as for example acute trauma with fracture or cruciate ligament rupture, organ disease such as acute pancreatitis and acute Neu- romuscular disease and metabolic non-neurological disease can cause general weakness and associated alterations of body posture.
Test
CNS/PNS structures involved
Body posture
Examine the patient standing
Evaluate head position: Abnormal  ndings might be a lowered head indicating neck pain or weakness - or head tilt indicating vestibular disease
Evaluate position of the limbs (abnormal  ndings might be a broad based stance indicating balance problems and vestibular disease)
If the patient is non-ambulatory examine the cause for this further
The lesion must be localized to speci c structures of the CNS or PNS by performing a full neurological examination
Certain body postures are strong indicators of involve- ment of speci c neuroanatomical structures. One very common change of body posture is head tilt which is associated with vestibular disease (central or peripheral).
A number of very characteristic abnormal body positions are listed below in table 1.
