Ohm's Law states that an electrical circuit's current is directly proportional to its voltage, and inversely proportional to its resistance. So, if voltage increases, for example, the current will also increase, and if resistance increases, current decreases; both situations directly influence the efficiency of electrical circuits.
Lumbosacral Radiculopathy Definition. Lumbosacral radiculopathy is a broad term referring to a range of symptoms associated with the nerves of the lumbosacral plexus in the lower back. The lumbosacral plexus encompasses the nerves that exit the spinal cord at the lumbar, sacral and coccygeal regions of the spine.Radiculopathy occurs when an anatomical abnormality has caused one or more of these nerves to become irritated, pinched or impinged.he lumbosacral plexus encompasses the nerves that exit the spinal cord at the lumbar, sacral and coccygeal regions of the spine.

Syndromes associated with lumbosacral radiculopathies. Posterior sciatica. * pain which radiates along the posterior thigh and the posterolateral aspect of the leg is due to an S1 or L5 radiculopathy (nerve roots). When caused by S1 irritation it may proceed to the lateral aspect of the foot; pain due to L5 radiculopathy may radiate to the dorsum of the foot and to the large toe.
