In a normal person, when a muscle tendon is tapped briskly, the muscle immediately contracts due to a two-neuron reflex arc involving the spinal or brainstem segment that innervates the muscle. The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon organ associated with the muscles; the efferent neuron is an alpha motoneuron in the anterior horn of the cord. The cerebral cortex and a number of brainstem nuclei exert influence over the sensory input of the muscle spindles by means of the gamma motoneurons that are located in the anterior horn; these neurons supply a set of muscle fibers that control the length of the muscle spindle itself. Hyporeflexia is an absent or diminished response to tapping. It usually indicates a disease that involves one or more of the components of the two-neuron reflex arc itself. Hyperreflexia refers to hyperactive or repeating (clonic) reflexes. These usually indicate an interruption of corticospinal and other descending pathways that influence the reflex arc due to a suprasegmental lesion, that is, a lesion above the level of the spinal reflex pathways.

ost of us come across this particular sign quite often. Of course, you can just jump to the numerous investigations and one after another, rule out the possible causes, finally getting to the diagnosis. For me, that’s no fun at all. Although I still don’t know whether I am going to become a surgeon or not (embarassing for me, since I’m going to be done with med-school this year), its pretty fascinating. If I were to work in a country whether investigations aren’t that expensive, I would definitely just perform a small examination and take a short history, sending off my patient to get a myriad of investigations, reporting to me after a while, with the diagnosis in his reports.
