Hi I'm looking for info on a research project into the training effect after children have been given new orthotics/gait aids (either for the first time or a new design). The liturature shows a need to measure the child's physiological as well as anatomical affects of new orthotics/gait aids, but exactly how long after they begin to where them? Is there an immediate increase in effeciency(therefore decrease in heart rate?) when gait is corrected or is there a training effect? Have there been studies done? Am I reinventing the wheel?? thanks Beccy Rowse %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
