Weakness, Atrophy


  Here is a dumb question.  Is Muscle Weakness due to a compressed nerve the same as Muscle Atrophy?  If not, what is difference?  Thanks!  Greg
========================================================================
Thanks for your question.  A nerve damaged by compression will result in weakness in the innervated muscle, and over a period of time one will observe atrophy of that muscle.  However, one can also observe muscle weakness in other neurological impairments, such as a stroke, where the peripheral nerve is actually intact.  Other mechanism for muscle weakness is a defect in the neuro-muscular junction, so that the communication between the nerve and the muscle is impaired, such as in Myasthenia Gravis.
I hope this information is useful.  Best of luck.
