Analysis of whole body coordination during walking:
quantitative mathematical analysis of the nature and degree of coupling between limbs and how it changes with speed of walking.
Balancing a stick on the finger:
a study of how the nervous system learns to control an inherently unstable object.
Coordination of limb segments and the whole body during pistol shooting:
an investigation of differences between novice and skilled shooters.
Kinetics of skilled and unskilled ball bouncing:
an analysis of how bouncing is determined by the contact forces between the ball and hand and between the ball and ground.
Muscle stretch reflexes at the wrist:
an analysis of how joint mechanics – stiffness, viscosity, resonant frequency – are determined by the magnitude and timing of the reflex response.
An analysis of patterns of chest and abdominal breathing movements in normal speakers and people who stutter.
Reproducibility/variability of lip and jaw movements in normal speakers and people who stutter:
are speech movements in people who stutter less stable than in normal speakers?
Asymmetry of movement at the mouth in normal speakers and people who stutter.
The movements of the mouth are naturally asymmetrical in normal speakers, with a bias toward greater movement on the right than the left side. Are speech movements in people who stutter similarly asymmetrical?
Inter-limb coordination in cerebral palsy.
Two-handed movements have been reported to be performed better that one-handed movements in hemiplegic stroke patients. Is this also true in hemiplegic cerebral palsy?
Control of force in cerebral palsy:
the normal human motor system is ‘noisy’ and the noise increases with the level of muscle force used in a task. Is the noise-force relation the same in cerebral palsy?
