How does dystonia affect my bones?

Dystonia does not have a primary effect on bones, but because of the abnormal postures that result from dystonic spasms, unusual mechanical stress may be placed on bones. For instance, if someone has a severe dystonia that involves a very sustained posture in one position, he or she may get a shortening of the ligaments and tendons so that the joint becomes "contracted" and can no longer move freely through a full range of motion. With time, this might be expected to cause excessive wear on the affected bones. Even short of a contracture, some bones may experience excessive wear because of such abnormal mechanical stresses. Bone changes, however, are not usually symptomatically important to people with dystonia. It is more often the case that doctors are concerned about dystonia's effect on muscles and related supportive tissues as they influence posture.
