Hypotonia is often a condition of abnormally low muscle tone (the quantity of anxiety or resistance to motion in a muscle), often involving reduced muscle strength. Hypotonia is not a distinct medical disorder, but a potential manifestation of many different ailments and disorders that impact motor nerve manage through the mind or muscle strength. Recognizing hypotonia, even in earlier infancy, is frequently relatively straightforward, but diagnosing the underlying contribute to are usually difficult and often unsuccessful.
Hypotonia is often a medical phrase applied to describe decreased muscle tone (the quantity of resistance to motion in a muscle). its not the same as muscle weakness, while the two conditions can co-exist. Hypotonia could possibly be a result of trauma, environmental factors, or by genetic, muscle, or central nervous system disorders, including down syndrome, muscular dystrophy, cerebral palsy, Prader-Willi syndrome, myotonic dystrophy, and Tay-Sachs disease. sometimes it could possibly not be feasible to come across what causes hypotonia.
An infant with hypotonia exhibits a floppy quality or “rag doll” sensation when he or she is held. Infants with this problem lag behind in acquiring certain very good and gross motor developmental milestones that enable a baby to hold his / her mind up when positioned on the stomach, stability themselves or get into a sitting position and remain seated with out falling over.
Symptoms of Hypotonia
The most common symptoms of hypotonia involve troubles with mobility and posture, inhalation and speech difficulties, lethargy, ligament and joint laxity, and bad reflexes.
Infants who are hypotonic will allow their elbows and knees hang loosely instead of flexed as normal. The infant could possibly have bad or no mind control.
The extent and occurrence of distinct objective manifestations depends upon the age with the patient, the severity with the hypotonia, the distinct muscles affected, and sometimes the underlying cause. For instance, some hypotonics could possibly experience constipation, while others have no bowel problems.
Twitching could possibly occur in the tongue and in affected limbs. The individual could possibly experience muscle pain and muscle cramps. Some patients experience alot more difficulty swallowing saliva and liquids than solid food.
Since hypotonia is most often diagnosed during infancy, its also known as “floppy infant syndrome” or “infantile hypotonia.” Infants who suffer from hypotonia are often described as sensation and appearing as though they are “rag dolls” or perhaps a “sack of jello,” easily slipping through one’s hands.
Causes of Hypotonia
Hypotonia could possibly be a result of trauma, environmental factors, or by genetic, muscle, or central nervous system disorders.
Down syndrome happens when there is an extra duplicate of chromosome 21. This type of down syndrome is referred to as Trisomy 21. The extra chromosome causes troubles with the way the body and mind develop.
Hypotonia are usually a result of a variety of conditions including those that involve the central nervous system, muscle disorders and genetic disorders. Some common causes can contain but are not limited to down syndrome, Muscular dystrophy, Cerebral palsy, Prader-Willi Syndrome, Myotonic dystrophy, Marfan syndrome and Tay-Sachs disease.
A number of different genetic disorders are associated with hypotonia, and could possibly impact the nerves (and by extension the muscles), or even the muscles only. Most genetic conditions are generalized (affecting multiple muscle groups) and progressive. Some genetic conditions are hereditary.
Myasthenia gravis: a neuromuscular disorder characterized by varying weakness of voluntary muscles, which often increases with relaxation and worsens with activity. The condition is a result of an abnormal immune response.
