Investigation of Motor Functions

  • Aleksandr Romanovich Luria


Investigation of motor function for diagnostic localization involves an analysis of the complex forms of construction of voluntary movements known in clinical neurology as praxis. They may be disturbed by lesions of various divisions of the cerebral cortex. As mentioned (Part II, Section 4A and B), a disturbance of the complex forms of organization of the motor act cannot be sharply demarcated from a disturbance of the more elementary forms of movement. The investigation of motor functions should therefore begin with a short analysis of the state of the elementary components of the motor act with a view to ascertaining the degree to which they remain intact: this will facilitate the study of the more complex forms of voluntary movement.
