Dr. Van Emmerik's research is in the area of motor control and coordination.
In his research, he applies principles from complex and nonlinear dynamical
systems to the study of posture and locomotion. The particular emphasis
in his research is on mechanisms of stability and adaptability in movement
coordination. An important research focus is the role of variability
in the control of movement. He has extensive experience in the area
of balance and gait disorders due to aging and neurological disease,
such as Parkinson's disease and Multiple Sclerosis.

Motor Control and Coordination Changes and Movement Stability
in Locomotion and Posture in Learning,
Movement Disorders, and Development
Current research projects involve (1) the effects of fatigue on balance
and postural control in Multiple Sclerosis. (2) Assessment of changes
in balance control in Parkinson's disease and older individuals with
and without a tendency of falling. (3) The development of postural and
manual control in young children, with a particular focus on how the
interaction between these systems develops and changes across the life
span. (4) The role of eye-head and trunk coordination in stability and
adaptability of gait, and changes in these coordinative patterns due
to aging and disease. 5) The integration of locomotion and respiration
during walking, assessing the dual role of the trunk in respiration
and maintaining postural stability during locomotion.
