SUPPORTS (?) YOUR

" ...it may be

CAVEAT - IT IS WIKIPEDIA

ALSO CAVEAT ...

Quoting "Schulz, Brian W." :

> I friend of mine recently ruptured his plantaris muscle in his one leg
> and subsequently started to hyperextend his knee on that side during
> gait. His orthopedic surgeon dismissed the plantaris rupture as a
> possible cause for this hyperextension out of hand as the plantaris is
> "a vestigial structure". While the plantaris may be far smaller and
> weaker in humans than in cats and non-human primates, it may be
> important in proprioception, but I have not been able to find any
> evidence of its utility. Does anyone know of any evidence for the
> importance of plantaris proprioception in gait or any possible
> mechanism, neural or mechanistic, why plantaris rupture could result in
> knee hyperextension during gait?
