Denervation

Posted By George on November 26, 1998 at 20:07:04:








1. In relation to ALS being progressive,  if EMG shows denerving of a muscle, how soon would symptoms develop in that muscle, ie weakness, fasiculations, atrophy etc.obviously we are not talking exact times, but are we talking, fairly quickly, or can the denerving be there for months/years prior to any symptoms.
2. If an EMG picks up muscle denervation, does this mean that the muscle is denerving or has denerved?
In relation to ALS do symptoms develop during denerving or after denerving of a muscle. Ie Do fasiculations occur as muscle is denerving or after the muscle has denerved.
3. Can one increase muscle size to muscles that are apparently showing signs of denervation. Eg weight lifting. running etc.
Thank you.
