Force analysis of an electrically induced isometric contraction of the knee muscles as a technique for osteogenesis

The purpose of this study was to quantitatively measure the strain induced upon the bone by an electrically induced contraction of the muscles in order to analyse the potential of using Functional Electrical Stimulation (FES) as a method for targeted osetogenesis. With the force output of a joint during a contraction and anthropological measurements, we determined the force of the muscle contraction at the muscle origin and insertion points on the bone. We applied these internal force measurements to a femur model to determine the strain on the bone. The level of strain observed governs the amount of loading cycles required, and therefore the practicality for its use as therapy.
