Ergonomics and the physiotherapist: a report on a research project on working postures

In a series of lectures on biomechanical principles, Professor E. R. Tichauer, an authority on man-machine-task systems, stated: "Only a few years ago, the physical work load imposed on the individual employee was much heavier than is the case today, but it was, in many occupations, fairly evenly distributed over the entire musculo skeletal system. Today, the total energy demanded from man in the performance of an industrial task has often been reduced, but stress is concentrated on individual and small components of the worker's anatomy," The techniques for combating these new stresses are found in the science of ergonomics (Hopkins 1966).
