Difference between reciprocal inhibition and regular muscle movement?
What is the difference between reciprocal inhibition and regular muscle movement?


Reciprocal inhibition is part of regular muscle movement. It is controlled by the stretch reflex controlled by the muscle spindle. It's an important part of a functioning muscle and spinal cord, and not pathologic at all. However, this same reflex, in an excessively tight muscle on one end of a joint, would cause an excessively loose muscle on another end of a joint. 

Here is an image showing this reflex, from Brust Practice of Neural Science, Chapter 6.


I can't give you any medical advice on this site, so I can't put that in context, but I think that answers your biology question.
