Spatial versus temporal inhibition in dystonia

Dystonia is a motor disorder characterized by involuntary muscle contractions, frequently causing twisted postures. A pathophysiological hallmark of dystonia is reduced motor inhibition at multiple levels of the central nervous system including the spinal cord, brainstem and cortex. In addition, it is widely accepted that the sensory system is involved in dystonia. A well-known and fascinating phenomenon is the sensory trick. Touching a body part, usually at a location close to where dystonia occurs such as the neck or face in cervical dystonia or blepharospasm, alleviates dystonia symptoms.
