What describes hypotonia?

Hypotonia is characterized by weak, floppy muscles, which affects an individual's overall muscle tone and strength. This condition can influence a person's ability to maintain posture, perform movements, and engage in everyday physical activities. Muscles display reduced resistance to passive stretching, which can lead to difficulties in coordination and balance. In contrast, the other options describe conditions or symptoms that do not align with the definition of hypotonia. Severe muscle rigidity pertains to hypertonia, which involves excessively tight or stiff muscles, while poor sensory perception and the development of muscle spasms relate to different neurological or muscular conditions. Therefore, the description of weak, floppy muscles accurately captures the essence of hypotonia.
