This involves measurement of human response to single impacts and cumulative impact exposure, including spinal accelerations, internal pressure, emg activity, subjective tolerance and fatigue. A biodynamic model of the human response to impacts is under development, which will be integrated with cumulative dose and injury risk models to assess health effects. This involves computer generation of 3-dimensional limb shapes from anthropometric measures of the patient, and the alignment and blending of the cosmetic limb shape with the socket and foot shapes to create a single entity. I am also interested in the analysis of muscle and joint forces during human locomotion. Recent studies have investigated the load transmission across the fracture callous of long bones.
Research is in progress to develop a microprocessor alignment coupling for below knee prostheses.
