How deep are you willing to take your gait understanding ?
“In conclusion, these data suggest that the gait and balance deficits in higher level gait disorders (HLGD) mainly result from the lesion or dysfunction of the network linking the primary motor cortex and the mesencephalic locomotor region (MLR), brain regions known to be involved in the control of gait and balance, whereas cognitive and ‘appendicular’ hypokinetic-rigid signs mainly result from deep white matter lesions (DWML) that could be responsible for a dysfunction of the frontal cortico-basal ganglia loops.”
