How does muscular dystrophy affect walking?
How does muscular dystrophy affect walking?
By school age, children may walk on their toes or the balls of their feet with a slightly waddling gait and fall frequently. To try to keep their balance, they may stick out their bellies and pull back their shoulders. Children also have difficulty raising their arms.
What muscles would be involved in walking on the toes?
- Gastrocnemius muscle. This is the larger calf muscle. Its two parts form the bulge that is visible beneath the skin.
- Soleus muscle. This smaller, flat muscle lies underneath the gastrocnemius muscle.
Why do DMD patients walk on their toes?
In DMD, lower-extremity muscles progressively weaken as they degenerate and are replaced by fibrous tissue. Toe walking results from the relatively greater weakening of the dorsiflexors of the foot as compared with the plantarflexors. Toe walking also develops to compensate for the weakening quadriceps muscle.
What muscles are weak in toe walking?
Children who walk on their toes can develop tight calf muscles on the backs of their legs and have decreased movement of their ankles. In addition, the muscles on the front of their legs may become weak. If there is tightness and weakness, your child will have difficulty walking on their heels.
What is toe walking indicative of?
Typically, toe walking is a habit that develops when a child learns to walk. In a few cases, toe walking is caused by an underlying condition, such as: A short Achilles tendon. This tendon links the lower leg muscles to the back of the heel bone. If it’s too short, it can prevent the heel from touching the ground.
When do DMD stop walking?
In the “tween” and teen years there is a continuous progression of muscle weakness. By about 12 years of age, most people with Duchenne are unable to walk and need to use a power wheelchair on a regular basis.
Why does my 7 year old walk on his tiptoes?
Typically, toe walking is a habit that develops when a child learns to walk. In a few cases, toe walking is caused by an underlying condition, such as: A short Achilles tendon. This tendon links the lower leg muscles to the back of the heel bone.
Can you walk on Your Toes with Duchenne muscular dystrophy?
Walking on the toes is one of the hallmark signs of Duchenne muscular dystrophy, and it can also occur in Becker muscular dystrophy. In addition, patients with limb-girdle muscular dystrophy sometimes experience difficulty lifting the front of their foot from the ground. This leads to both tripping and toe-walking.
Can a person with muscular dystrophy drop their feet?
A muscular dystrophy patient may experience problems with the muscles in the foot responsible for lifting the front of the foot when walking. When the muscle fibers in these muscles become damaged and subsequently repaired by scar tissue, the muscle will not be able to contract and relax properly. This impairment can result in foot drop.
What are the main symptoms of muscular dystrophy?
Muscle weakness is one of the main symptoms found in all subtypes of muscular dystrophy. Every form of muscular dystrophy includes progressive weakening of the muscles and muscle atrophy. However, the groups of muscles affected vary from case to case.
What causes a Trendelenburg gait in muscular dystrophy?
A Trendelenburg gait is caused by weakness in the hip muscles, and while it can be a sign of multiple subtypes of muscular dystrophy, but it isn’t always. Other conditions that can cause a Trendelenburg gait are nerve damage, osteoarthritis, cleidocranial dysostosis, and poliomyelitis.
What causes a person to walk on their toes?
Cerebral palsy. Toe walking can be caused by a disorder of movement, muscle tone or posture caused by injury or abnormal development in the parts of the immature brain that control muscle function.
What are the symptoms of myotonic muscular dystrophy?
Myotonic. This is characterized by an inability to relax muscles following contractions. Facial and neck muscles are usually the first to be affected. People with this form typically have long, thin faces; drooping eyelids; and swanlike necks.
What kind of muscles are affected by muscular dystrophy?
Hip and shoulder muscles are usually affected first. People with this type of muscular dystrophy might have difficulty lifting the front part of the foot and so might trip frequently. Onset usually begins in childhood or the teenage years.
What are the symptoms of Becker muscular dystrophy?
Becker muscular dystrophy. Signs and symptoms are similar to those of Duchenne muscular dystrophy, but tend to be milder and progress more slowly. Symptoms generally begin in the teens but may not occur until the mid-20s or even later.
