Abstract
High speed motion analysis techniques in 3-D are used to demonstrate that the magnitude of the corrective forces made by a finger of a trained individual during stick balancing are self-similar and in particular are described by a truncated Levy flight (TLF). The presence of scaling in a balancing task requires that current theories of motor control be re-evaluated.
