Most commonly, foot drop is caused by an injury to the peroneal nerve. The peroneal nerve is a branch of the sciatic nerve that wraps from the back of the knee to the front of the shin.

The motor function of the common peroneal nerve is the dorsiflexion or “picking up” of the foot. Therefore, it can be responsible for a common but troubling motor condition called “foot drop”.

People with severe valgus deformities of the knee are at an increased risk for peroneal injury and resulting postoperative foot drop following total knee arthroplasty (TKA). The common peroneal ...

H.S. Dear H.S.: “Foot drop” is a simple name for a complex issue. It almost always involves damage to a nerve. The nerves to the muscles that hold up the foot come off the spinal column at L4 ...

The University of Houston researchers found that systolic blood pressure can be decreased by 10% in 60 minutes and 16% in 120 minutes after nerve stimulation. The results indicate that deep peroneal ...

“Our results indicate that DPNS consistently induces an immediate and reproducible arterial depressor effect in response to electrical stimulation of the deep peroneal nerve,” reports Romero-Ortega.

The nerves to the muscles that hold up the foot come off the spinal column at L4/L5, travel down the sciatic nerve and then branch off as the peroneal nerve. Foot drop can result from damage at ...

Everything I’m reading says that the quicker a drop foot is addressed (in terms of finding out the reason — a compressed or damaged nerve — and getting that dealt with medically), the better ...
