title: Why the upper limbs move during human walking.
abstract: It has long been held that the movement of the upper limbs during walking counteracts the rotation of the shoulders about the longitudinal axis of the body. Alternative theories of the need for upper limb movement are discussed, and it is shown that controlled upper limb movement produced under the control of centres within the spinal cord is a necessary component of smooth non-jerky locomotion.
