Beckers muscular dystrophy is very similar to Duchennes, however the dystrophin gene is less severely affected and maintains some of its function. The clinical course is less predictable than Duchennes. Symptoms only start to appear around 8 – 12 years. Some patient require wheelchairs in their late 20s or 30s . Others able to walk with assistance into later adulthood. Management is similar to Duchennes.
myotonic dystrophy
Myotonic dystrophy is a genetic disorder that usually presents in adulthood. Typical features are:
Progressive muscle weakness
Prolonged muscle contractions
Cataracts
Cardiac arrhythmias
TOM TIP: The key feature of myotonic dystrophy to remember is the prolonged muscle contraction. This may present in exams with a patient that is unable to let go after shaking someones hand, or unable to release their grip on a doorknob after opening a door. When doing an upper limb neurological examination always shake the patients hand and observe for difficulty releasing their grip

A classic initial symptom is sleeping with their eyes slightly open and weakness in pursing their lips. They are unable to blow their cheeks out without air leaking from their mouth.

It typically presents with bilateral ptosis, restricted eye movement and swallowing problems. Muscles around the limb girdles are also affected to varying degrees
Limb girdle MD
Limb-girdle muscular dystrophy usually presents in teenage years with progressive weakness around the limb girdles (hips and shoulders)
