Myotonic Dystrophy

What is Myotonic Dystrophy?

Myotonic Dystrophy (DM) is a muscle weakening disorder which is inherited. It is abbreviated to DM because the Latin name for this condition is 'Dystrophia Myotonica'. In DM, a defective gene causes progressive muscle weakness accompanied by delayed relaxation of muscles after contraction which is called myotonia. It is a multi-systemic disorder, this means that  the effects are not limited to the voluntary muscle system, but can also affect tissues and organs throughout the body. Primarily the muscles of the face, neck, hands, forearms and feet are affected, although DM can have a wide range of different effects on different individuals.

Some of the information is not relevant to MDANZ members but the condition information is really good and well worth a look. There is reference to a Health Passport in this resource and this is available in NZ here or by contacting us on 0800 800 337 or email [email protected]

This diagram shows the location of the genetic error which causes Myotonic Dystrophy.
One copy of the gene with an error is enough to cause the condition.
Type 1 is caused by an error in the DMPK gene on chromosome 19 and Type 2 is caused by an error in the CNBP gene on chromsome 3.

  • Care Considerations for people with MD - These recommendations are intended to help standardize and elevate care for people with myotonic dystrophy and reduce variability in clinical trial and study environments.

  • MDF Anaesthesia Guidelines - The use of anesthesia raises special risks to DM patients, which include heightened sensitivity to sedatives and analgesics. Serious complications are most common in the post-anesthesia period when risk of aspiration and other complications are increased.
  • User Guide: Care Pathway Toolkit for MD - The integrated care pathway tool for the myotonic dystrophy type 1 clientele (DM1-ICP) was developed to be used within the nursing practice for individuals with a late or adult DM1 phenotype. This tool can be used for initial evaluation and regular follow-up at neuromuscular disease clinics and homecare visits. The DM1-ICP is a tool that was designed to support the nursing practice but does not replace nurse autonomy or critical judgment. It was developed to respond to several needs, including: 1) The need to review the services offered to ensure better use of professional resources; 2) The need to integrate evidence-based data within the nursing practice.
