Pusher Behaviour
A neurological phenomenon where patients actively push away from their unaffected side toward their paralyzed side.
Full Definition
Pusher behaviour, also known as contraversive pushing, is a disorder of postural control that occurs in some stroke patients, particularly those with right hemisphere lesions. Patients actively resist any attempt to move their body toward the unaffected side and instead push toward their paralyzed side, even when this creates instability. This behaviour significantly impacts rehabilitation outcomes and fall risk. The condition is distinct from simple postural asymmetry and requires specific therapeutic interventions. Assessment typically involves the Burke Lateropulsion Scale or similar standardized measures.
Usage
Usage note: Note the distinction between 'pusher behaviour' and 'pusher syndrome' - the former is more precise terminology.
