What is the typical presentation of mixed tone?

• A. low tone proximally (Head & trunk control) and higher tone distally (extremities)
• B. high tone proximally and low tone distally
• C. symmetrical tone throughout body
• D. fluctuating tone with movement

Answer: (A)

Mixed tone means you see a mix of hypo- and hypertonia across different parts of the body. The most typical presentation is reduced tone in the proximal regions—head and trunk control—so the trunk is often floppy and posture unstable. At the same time, the distal portions (the arms and legs) can have higher tone, showing increased resistance to movement and stiffer extremities. This combination explains why someone might have poor head and trunk control while their hands and feet become rigid or awkward in movement. The other patterns—high tone in the trunk with low tone in the limbs, uniform tone throughout the body, or tone that fluctuates with movement—don’t match the common distribution seen in mixed tone.
