: Hello. I posted earlier complaining of clonus. Last night after dancing for 3 hours, my calves had severe clonus. They shook like crazy. There was no weakness, just severe shaking if shifted my weight to the balls of my feet. I was out with a doctor friend who said it was exercise induced clonus. Is that a genuine diagnosis? I mean why would exercise cause clonus? I have always been a runner and never had to deal with this before, but now after running 4 miles, the same thing happens. He said not to worry about it since I have no associated weakness, but I can't help but wonder/worry what brought this all on suddenly. I am 26 now, and when I was 14 I had a pretty bad sledding accident where I landed on my back on a cement parking lot and lost feeling in my legs for a few minutes. Could this be related to an accident that happened 12 years ago??? My back doesn't bother me at all though. Also, the clonus is worse on the right side. What would cause this? Does clonus ever resolve itself? Can it get any worse? I had a nerve conduction study/EMG in July for fasciculations which was completely normal. Is this test enough to rule out a serious cause for the clonus? I am such an active/physical person, and this scares me! Any help would be certainly appreciated. Thanks so much for this forum!
Hi, Robin,
Your symtoms seem to be more like muscle cramps than clonus in the medical terms. This kind condition is acturally quite common. The level of tolerance of muscles to exercise varies significantly from person to person. Exercise causes ischemia in muscles. Most people dont have problems with a benign transient ischemia, and they recover with rest. However, certain neurological diseases are related to muscle cramps. Such patients have a much lower threshold to exercise induced muscle ischemia, reflecting the abnormal underlying biochemical status. I can not be sure which catagory your condition belongs to without a thorough evaluation. EMG is usually helpful of telling abnormal muscle electricity at the neuromuscular junction level. However, EMG is not 100% sensative to every abnormality. In addition, to be certain about your clonus, you need a full neurological visit. If you like such evaluation to be done here at the Clinic, do not hesitate to call (800) CCF-CARE ext. 45559.
