This definition, unlike the previous definition, does include people with dystonia who have muscle contractions that are not sustained but alternate with periods of normal or even reduced tone (thus the name dys-tonia). Unfortunately, this definition is not easy to apply and is not specific. The definition applies to all forms of tremor, and there are symptoms consisting of sustained contractions that are not considered dystonia. 9 They include splinting to reduce pain (atlantoaxial subluxation, painful neck and back 28 Hyperkinetic Movement Disorders tumors, back pain for other reasons), neuromuscular causes of muscle spasm, and others—see Table 3–2.
It is not known whether this is the coincidence of a common disease (ET) with an uncommon symptom (dystonia) or evidence of an etiologic or genetic relationship. Also, because the amplitude of ET depends in part on the mass of the shaking body part, some people with ET will tighten all the muscles of the arm while writing to increase the mass that is shaking and dampen the tremor. This sustained muscle tightening can resemble writer’s cramp (brachial dystonia), and in some people with ET this trick is automatic and hard to voluntarily suppress.
People with CD sometimes have superimposed brief, painful spasms that are usually very disabling. Finally, embarrassment is disruptive for many people. A peculiar feature of CD is that patients occasionally have spontaneous remissions! 16 Some patients can have multiple remissions and relapses. Equally amazing is that some patients who remit may have a different head position if they relapse. Patients with severe chronic CD are at risk for radiculopathy and myelopathy. 17 The significance of this is not known, but it suggests that mild scoliosis may be a manifestation of dystonia.
