How does Down syndrome affect the joints?

How does Down syndrome affect the joints?

The most common musculoskeletal effects of Down syndrome include weak muscle tone (hypotonia) and ligaments that are too loose (ligament laxity). This leads to excessive joint flexibility.

Are Down syndrome people double jointed?

Trisomy 21 Program This is one reason they are so flexible and are often referred to as “double jointed.” They don’t actually have double joints, but have excessive movement and ligamentous laxity. Babies are especially flexible because their muscles, joints and bones have not developed to provide additional stability.

What are 3 characteristics of Down syndrome?

In Down syndrome, there are three copies, either complete or partial, of chromosome 21. The characteristics of Down syndrome include low muscle tone, short stature, a flat nasal bridge, and a protruding tongue. People with Down syndrome have a higher risk of some conditions, including Alzheimer’s disease and epilepsy.

What are 5 features recognized in a Down’s syndrome individual?

Facts about Down Syndrome

• A flattened face, especially the bridge of the nose.
• Almond-shaped eyes that slant up.
• A short neck.
• Small ears.
• A tongue that tends to stick out of the mouth.
• Tiny white spots on the iris (colored part) of the eye.
• Small hands and feet.
• A single line across the palm of the hand (palmar crease)

What parts of the body are affected by Down syndrome?

Organs affected by Down Syndrome

• Heart.
• Gut.
• Ears.
• Eyes.
• Thyroid gland.
• Brain.
• Spine.
• Miscellaneous.

How does Down syndrome affect physical?

Children with Down Syndrome tend to have quite floppy muscles (hypotonia or low muscle tone). This makes it harder for them to move and can affect all aspects of their physical development.

What body parts does Down syndrome affect?

Do people with Down syndrome have weaker bones?

Persons with Down syndrome (DS) have shown diminished levels of bone mass compared with those without DS [1–4]; therefore, DS population might be considered as a population at higher risk of suffering bone fractures and osteoporosis.

What part of the body does Down syndrome generally affect?

Down syndrome, the most common chromosome-related genetic condition in the U.S., affects development of the brain and body.

What is the main problem of Down syndrome?

Potentially serious complications — The most serious complications of Down syndrome include heart defects, blood disorders that can include leukemia (cancer of the blood), and immune system problems. Heart defects — Approximately half of all babies with Down syndrome are born with (often repairable) heart defects.

At what age do Down syndrome babies walk?

For example the average age for walking in typically developing children is 13 months and the range is 9-17 months, while the average age for walking in children with Down syndrome is 24 months and the range is 13-48 months.

What is the most common cause of death in Down syndrome?

Heart and lung diseases are the leading causes of death for persons with Down syndrome. Pneumonia and infectious lung disease, congenital heart defect (CHD) and circulatory disease (vascular diseases not including CHD or ischaemic heart disease) account for ∼75% of all deaths in persons with Down syndrome.

Which is the most common congenital anomaly associated with Down syndrome?

ATRIOVENTRICULAR SEPTAL DEFECT (AVSD) AVSD is the most frequently diagnosed congenital heart condition in children with Down syndrome. Various studies place the incidence rate between 30 and 47 percent of CHDs in children with Down syndrome, according to the book Advances in Research on Down Syndrome.

What are the musculoskeletal effects of Down syndrome?

The most common musculoskeletal effects of Down syndrome include weak muscle tone (hypotonia) and ligaments that are too loose (ligament laxity). This leads to excessive joint flexibility. Joint Instability Children with Down syndrome may have hip, knee, and other joints that slip out of place or become dislocated. Hip instability.

What kind of joint instability does Down syndrome have?

Joint Instability. Children with Down syndrome may have hip, knee, and other joints that slip out of place or become dislocated. Hip instability. The hip is a “ball-and-socket” joint. In a normal hip, the ball of the upper end of the femur (thighbone) fits firmly into the acetabulum (socket).

How does Down syndrome affect posture control?

People with Down syndrome have more joint mobility than the average. The enlarged joint mobility may contribute to the lack of posture control. Together with the failure of co – contraction, it will affect the joint stability.

What is joint hypermobility syndrome (JMS)?

This may be a sign of what is known as joint hypermobility syndrome (JMS) or, more recently, hypermobility spectrum disorder (HSD). Hypermobile joints are a feature of genetic connective tissue disorders such as hypermobility spectrum disorder (HSD) or Ehlers–Danlos syndromes (EDS).
