First -- what are your symptoms in the legs that prompted this study? And where exactly are your symptoms (calf, shin, top vs bottom of the foot)?

Well, what this test is telling us is that there are some problems in your nerve conduction in the legs.

There is probably an issue with nerve damage, and this may be due to issues with the myelin covering of the nerve -- and it seems to be affecting the nerves in the lower leg.

So - this is telling you that there is a "neuropathy" -- which may be causing the symptoms of numbness or pain you are having in your lower legs. What exactly is the cause, however, is not able to be known from the results of the test, but it does help your doctors in showing that there is a problem with nerve conduction and neuropathy in the legs.
