PARATONIA Meaning and
Definition
-
Paratonia is a medical term used to describe a condition characterized by abnormal or involuntary resistance to passive movement of the limbs. It is typically observed in individuals with neurological disorders, such as dementia or Parkinson's disease. This form of resistance differs from the rigidity associated with Parkinson's disease, as it is not constant but rather fluctuates depending on the individual's cognitive state or level of arousal.
The term "paratonia" is derived from the Greek words "para," meaning alteration or deviation, and "tonus," which refers to the tension or firmness of a muscle. Paratonia is often seen as a manifestation of impaired motor control caused by neurological damage or dysfunction.
Clinically, paratonia is characterized by an inability to fully relax the muscles during passive movement. When an examiner attempts to move a patient's limb, there is resistance and increased muscle tone, giving the impression of "against" movement. This resistance may vary and can be either an increase in tone during attempted bending or extending of a limb.
In addition to neurological conditions, paratonia can also be associated with other factors such as anxiety, emotional stress, or pain. The presence of paratonia can significantly affect daily activities, as it can cause difficulties in mobility, transfers, and certain therapeutic interventions.
Treatment options for paratonia may vary, depending on the underlying cause and severity of the condition. Physical therapy, stretching exercises, and range-of-motion activities are commonly employed to improve muscle flexibility and motor control. Additionally, medication management and behavioral interventions may also be utilized to address any underlying neurological or psychological issues contributing to paratonia.
