  Hypotonia is another term for low muscle tone. Low muscle tone is not the same thing as muscle weakness-instead, it means that the muscles have decreased tension or resistance to movement. Hypotonia is not a single condition-it's actually a symptom that can be caused by a variety of things. Causes of hypotonia range from genetic disorders to environmental factors to traumatic brain injury. Because of its variety of causes, hypotonia can affect people of any age in a variety of ways.

  A Spotsylvania Regional Medical Center answered

  Treatment of hypotonia begins with a thorough diagnostic evaluation, including an assessment of motor and sensory skills, balance and coordination, mental status, reflexes, and functioning of the nerves. Diagnostic tests, such as a CT scan of the brain, an EMG to evaluate nerve and muscle function, or an EEG to measure electrical activity in the brain may also be necessary. Once a diagnosis has been made, the underlying condition is treated first, followed by symptomatic and supportive therapy for the hypotonia. Physical therapy can improve fine motor control and overall body strength. Occupational and speech-language therapy can help breathing, speech, and swallowing difficulties. Therapy for infants and young children may also include sensory stimulation programs.
