Which term describes a combination of low proximal tone and high distal tone?

• A. Dystonia
• B. Mixed Tone
• C. Tone
• D. Strength

Answer: (B)

Pattern of muscle tone can vary across a limb, with some regions more tense and others looser. When the shoulder and upper arm show low tone while the forearm or hand shows high tone, you’ve got a mix of tone levels within the same limb. That combination is described as mixed tone. It captures that not all muscles share the same amount of resistance to passive movement. Dystonia involves abnormal movements or postures due to sustained or intermittent muscle contractions, which goes beyond just describing a proximal-distal tone pattern. Saying tone simply isn’t specific enough to describe a pattern, and strength refers to how much force muscles can generate rather than how tense they are or how that tension is distributed.
