Muscular hypotonia is a loss of muscle tone. The causes of this condition can be either pathological or not. Certain diseases, such as Huntington's disease
, hemiplegia, or Parkinson's disease
can cause muscular hypotonia. This condition can also be induced by medicinal drugs
, such as neuroleptics
. It is the opposite of muscular hypertonia
, which induces an increase in muscle tone.
