Which of the following is a symptom associated with hypertonia?

Hypertonia is characterized by increased muscle tension and stiffness, which results in greater resistance to passive movement. This condition often leads to muscle contractions, where the muscles are excessively tight or rigid. The presence of muscle contractions can interfere with normal movement and can cause discomfort or pain.

In contrast, symptoms like weak floppy muscles are indicative of hypotonia, which is a different condition characterized by decreased muscle tone. Poor coordination and loss of balance can arise from various conditions, including neurological disorders or muscle weakness, but they are not definitive symptoms of hypertonia on their own. The hallmark of hypertonia is the presence of those increased muscle tensions and contractions that significantly restrict movement and affect physical capabilities.
