How does DMD affect movement?

DMD is characterized by weakness and wasting (atrophy) of the muscles of the pelvic area followed by the involvement of the shoulder muscles. As the disease progresses, muscle weakness and atrophy spread to affect the trunk and forearms and gradually progress to involve additional muscles of the body.

Which nerve is damaged in waddling gait?

superior gluteal nerve lesions
Bilateral superior gluteal nerve lesions often result in a waddling gait. The gluteus medius is a thick, fan-shaped muscle originating from the outer aspect of the ilium superiorly from the iliac crest, the middle gluteal nerve inferiorly and the gluteal line posteriorly.

Can DMD patients walk?

What to Expect. As your child gets older, their muscles will become weaker and they most likely won’t be able to walk. Many boys with DMD will need a wheelchair by the time they are 12 years old to help them get around.

What causes waddling gait in muscular dystrophy?

Waddling Gait in Muscular Dystrophy It’s one of four conditions caused by a change in a protein called dystrophin, which helps keep muscle cells together. Children with DMD walk with a waddling gait by the time they are school age.

When do the first symptoms of Duchenne muscular dystrophy occur?

Duchenne Muscular Dystrophy It usually starts when a child is between ages 2 and 5. Symptoms of Duchenne muscular dystrophy include: Muscle weakness that begins in the hips, pelvis, and legs. Difficulty standing.

What is the difference between muscular dystrophy and Duchenne muscular dystrophy?

Both Duchenne and Becker muscular dystrophy are caused by mutations in a protein called dystrophin. In Duchenne muscular dystrophy, functioning dystrophin is completely absent in muscle, while in Becker muscular dystrophy, there is some dystrophin present, although not enough for completely normal muscle function.

What causes Duchenne gait?

Introduction. Duchenne muscular dystrophy (DMD) is an X-linked recessive disorder caused by a lack of dystrophin, and has an overall incidence of 1 in 4700 male births. The progressive character of the disease is due to muscle wasting and its replacement by connective tissue.

What causes walking like a duck?

Walking like a duck or a pigeon can stem from alignment problems in the hip and lower leg. Depending on how the knees and feet are aligned and function mechanically, will determine how severely the toes turn outwards or inwards and the overall impact the condition has on a patient’s function.

What causes waddling gait in DMD?

Waddling Gait in Muscular Dystrophy Duchenne m uscular d ystrophy (DMD) is a genetic condition that causes muscle weakness that becomes more severe over time. It’s one of four conditions caused by a change in a protein called dystrophin, which helps keep muscle cells together.

What is a waddling gait in toddlers?

Waddling Gait in Toddlers A waddling gait is normal in children under the age of 3. When your child is just learning to walk, they walk with their feet wide apart and turned out. This helps them keep their balance as they take a lot of short steps.

What is the gait pattern of Duchenne muscular atrophy?

Duchenne Gait Pattern. Gait Posture 29 (1): 36-41 Muscle wasting in the quadriceps is affecting the knee movement in loading response, when patients trying to avoid flexion of the knee. Furthermore, the knee hyperextension later in stance might be due to an attempt to keep the body stable while compensating for the weak quadriceps.

What is the Duchenne gait in LCP?

The Duchenne gait in LCP, Becker and other similar conditions is characterized by: A trunk lean toward the affected stance limb. The pelvis is either level or elevated on the swinging limb side, during the single stance phace. A reduced hip abductor moment, producing a hip-unloading effect.
