Hyporeflexia is the opposite condition to hyperreflexia and is characterized by under-active reflexes. This condition can come as a result of a spinal cord injury directly affecting the lower and/or upper spine area.
Hyperreflexia is a condition characterizing over-responsive reflexes. Spasms and twitches can be signs of this condition. Unlike hypoflexia, hyperreflexia generally affects higher centers of the human body – upper motor neurons.
Areflexia is known as the absence of reflexes and is often tested using a reflex hammer. This term is often associated with hyporeflexia, which is characterized by below average reflexes. This condition often affects the spine and associated muscles. The opposite of hypoflexia is hyperflexia – also covered here in Dr. Leone’s Knowledge Center.
