Which sign indicates decreased muscle tone?

Explanation:
Muscle tone is the baseline resistance a muscle offers to passive movement. When tone is decreased, the muscles feel floppy and show reduced resistance to being moved, a finding called hypotonia. This often presents as limbs that are easily moved with little stiffness and may be accompanied by reduced reflex responses. Tremor refers to rhythmic shaking and does not reflect lower baseline muscle tone. Dysmetria is a coordination error in limb movement, typically from cerebellar dysfunction, not a change in tone. Nystagmus is involuntary eye movement, unrelated to muscle tone. So the sign that best indicates decreased muscle tone is hypotonia.
