Motor control

Motor control (Hagbarth, Axelsson): For many years research was focused on spinal reflexes and control mechanisms important for normal movement. These control mechanisms may be disturbed in patients with different types of movement disorders. Of special interest was research amied at defining the function of muscle spindles and the fusimotor system. In later years the project have been concentrated on investigating the mechanisms of muscle thixotropy. Thixotropy means ”changed by touch”. A thixotropic substance acts like a semisolid gel but becomes more fluid and compliant when mechanically disturbed. It returns to its previous more solid state after a certain time of rest. Human skeletal muscles posseses thixotropic properties. The stiffness or mechanical resistance of both intra- and extrafusal muscle fibres is depending on the immediate preceding mechanical history of the muscle. Studies have shown that the motor control system must adjust for thixotropy dependant changes in extrafusal muscle stiffness.
