Motor Nerve Hyperexcitability and Muscle Cramps in Machado-Joseph Disease

Arch Neurol. 2009;66(1):138-141. doi:10.1001/archneurol.2008.515

We read the article by França et al1 with great interest. We thank them for confirming our previous results regarding the high frequency of and disability associated with muscle cramps2 in a larger sample of patients with Machado-Joseph disease (MJD). We would like to raise some concerns regarding the authors' interpretation of the findings.
