- Abstract
- (en) The representation of the longitudinal bodyaxis(LBA)is an impotant component of the body scheme, critical for controlling the erectstanc,hence has garnered much interest in basic and clinial neurosciences. LBA representation is a projection of the egocentric reference onto the coronal plane, complementary to the representation of the straight ahead, which is a projection of the egocentric reference onto the transverse plane. The clinical assessment of the LBA representation has been conceptualized in complete darkness and in the supineposition to accede to the component of the body scheme mainly based on somesthetic information and to be decorrelated from the interplay with gravity sensing. Participants indicate the orientation of an imaginary line going from the head to toe and passing through the “navel”, dividing the body into 2 symmetrical halves. This test isespecially relevant inindividual swith right hemisphere stroke, in whom a bias in the representation of the LBA partly underpins the wellknown weight-bearing asymmetry in standing and subsequent postural gait disorders.
