Muscular Dystrophies (MD) are a group of inherited genetic conditions that gradually cause muscles to weaken, according to the NHS.
MD is a progressive condition, meaning it worsens over time.
There is no cure for MD. However, treatment can help manage many of the symptoms.
More than 70,000 children and adults in the UK have MD or a related condition.
