Abstract : The thesis describes an experimental study which validates and extends a proposed model of position control in the human forearm. Comparisons are drawn between 'best-fit' theoretical curves, derived from the assumption of constant driving force, and actual distribution of phase trajectory data. At moderate to high velocities the data supports the assumption of constant driving force and optimal agonist-antagonist switching. Data of low variability is obtained t determine that the velocity feedback loop gain remains constant for all test conditions while the position feedback loop gain varies inversely with final position and directly with initial velocity signal.
