Atony means a decrease in the normal tone of an organ. This term is mainly used in connection with the muscles and defines a deficit in the strength of muscle contractions. Each muscle can be affected, those under voluntary control, but also the smooth muscles. Thus, for example, intestinal atony leads to a decrease in the speed of digestion and progresses to constipation. Atony is a symptom whose cause must be investigated and corrected to allow recovery of normal muscle tone. Forster's syndrome or atony-astasia is a congenital disease (present at birth) characterized by generalized muscle atony which causes major movement disorders.
