One of the ways in which
neuromuscular function can be characterised is
through video-based measurement of a person's movement. There are four
subject groups that we are evaluating: (1) normal children, aged 12 to 48
months, who are acquiring locomotor skills: (2)
children with cerebral palsy who are undergoing various forms of treatment
(e.g. muscle strengthening or neurosurgery); (3) athletes who have suffered a
partial or complete tear of their anterior cruciate
ligament in the knee; and (4) normal subjects who are studied while
exercising to fatigue. This project has an important link with a research
group at University College Dublin in Ireland that is financed
by the Wellcome Trust.
