What is repetitive exercise dystonia?

Repetitive exercise dystonia is a type of dystonia that is characterized by muscle spasms and involuntary movements that occur during or immediately after repetitive or sustained muscle contractions. This type of dystonia most commonly affects athletes or individuals who engage in repetitive physical activity, such as musicians, dancers, or keyboard typists.

Symptoms of repetitive exercise dystonia can include cramping, tremors, and abnormal postures in the affected muscles. These symptoms can appear during the activity and persist even after the activity has ceased. Over time, the symptoms of repetitive exercise dystonia can worsen, making it difficult or impossible for individuals to continue engaging in the affected activity.

The exact cause of repetitive exercise dystonia is unknown, but it is believed to be related to a combination of genetic, environmental, and lifestyle factors. Treatment for repetitive exercise dystonia can include physical therapy, medications, and in severe cases, surgery. In some cases, adjusting the activity or changing the way it is performed may also help manage symptoms.
