简要总结
Writer's cramp (WC) is a task specific dystonia that occurs from the moment patient starts writing. It leads to partial or complete inability to use the hand only during the handwriting gesture. It is characterized by the appearance of cramps or spasms of certain muscles of the hand and/or forearm.
Clinical scales currently use for the assessment of WC fail to accurately reflect changes in the characteristics of handwriting in response to treatments (Botulinum Neurotoxin injections and / or retraining therapy).
The Zigzag Tracking Task (ZZTT), easy to use in current practice provides useful information in terms of speed and precision of handwriting gesture. This timed handwriting test is to follow with a pen a zigzag path beset with obstacles to avoid. It permits to evaluate the time in seconds required to carry out the zigzag path and count the number of errors (output path and contacts with obstacles). The investigators propose to validate the ZZTT for the assessment of the handwriting gesture of WC.
