 The functional type of the popliteal vessel compression was first described by Rignault et al.in 1985 and labeled by Levien as type VI of the popliteal vessels entrapment syndrome.Exercise induced lower leg pain includes chronic exertional compartment syndrome, unresolved muscle strain (this classically occurs at the musculotendinous junction of the medial head of gastrocnemius), medial tibia stress syndrome, fibular and tibial stress fractures, fascial defects, nerve entrapment syndrome, vascular claudication (atherosclerotic or popliteal artery entrapment syndrome) and referred pain from lumbar disc herniation.
