Hi Sandie,

Thanks for your comment.



By no means should this be considered a full-blown analysis using the most appropriate scientific method - that is not what is being claimed. It is an interesting application of the VMG technology that demonstrates how much promise this modality hold for serious research. Especially when compared to electromyography, VMG offers a way to directly measure the mechanical impact of a muscle - not an inference derived from electrical impedance - so it eliminates some of the most irritating constraints that EMG imposes. This posting was made as a result of our investigations of protocols that will mimic the kind of inward rotational stress that is often associated with non-contact ACL tears and the sartorius appears to play an important role in maintaining stability in the knee. We were not specifically focusing on long-distance running, though we do believe it is relevant. Significantly more research has been done evaluating the vastus lateralis to biceps femoris as opposed to the sartorius, which is one reason why we were interested in looking at the contribution of the sartorius.
