Sensory trick phenomenon improves motor control in pianists with dystonia: prognostic value of glove-effect.

Musician's dystonia (MD) is a task-specific movement disorder that causes loss of voluntary motor control while playing the instrument. A subgroup of patients displays the so-called sensory trick: alteration of somatosensory input, e.g.

Musician's dystonia in pianists: long-term evaluation of retraining and other therapies.
