What is Hypotonia?
Hypotonia, marked by diminished muscle tone and weakness, is a condition where individuals may display reduced resistance to passive movement, resulting in floppy or limp muscles. It can manifest at birth or emerge during infancy, and infants with hypotonia often present a limp appearance, grappling with the challenge of sustaining bent knees and elbows.
Why Does Hypotonia Occur?
- Neurological Disorders: Conditions affecting the nervous system, such as cerebral palsy, brain malformations, or genetic disorders, can lead to hypotonia.
- Muscular Disorders: Some muscle diseases, like muscular dystrophy, can cause weak muscle tone.
- Metabolic Disorders: Certain metabolic conditions, such as mitochondrial disorders, may contribute to hypotonia.
- Genetic Factors: In some cases, hypotonia may be associated with genetic factors or syndromes.
How to Identify Hypotonia?
- Poor Muscle Control: Infants with hypotonia may have difficulty holding their heads up, sitting, or reaching developmental milestones.
- Floppy Appearance: Children or adults with hypotonia may appear floppy, with poor muscle tone and coordination.
- Speech and Motor Delays: Hypotonia can contribute to delays in speech development and motor skills.
- Fatigue: Individuals with hypotonia may tire easily due to increased effort required for movement.
