Motor Performance - Movement Time, Kinematic Analysis, Movement Subparsing, Force Production, Movement Variability And Coordination, Visual Monitoring

Research in motor control of aging humans has been centered around determining how motor performance is influenced by age, and around efforts to unravel the mechanisms that contribute to declines in motor performance. Changes are often characterized by slower and more variable movements, specifically slower initiation of movement, slower movement durations, declines in coordination of movement, reduced force production, coactivation of antagonist muscles during movement, and increased variability of movements (i.e., movements become inconsistent or varied from one use to the next). Specific examples of tasks that are linked to dimensions of motor control include goal-directed movements such as pointing, reaching and grasping, and aiming.
